TP2's Multimedia capabilities - Camera, Audio and Video...?? - Touch Pro2, Tilt 2 Windows Mobile General

Folks,
First off I realise that the TP2 is a business mobile so it has to make compromises and reading the reviews especially on GSM Arena I have picked up that the Camera is OKish with funny colouring, The Video is less good with low framerate ie 15fps as opposed to 30fps and the sound quality is average ie for MP3s.
Perhaps some of these will be improved via firmware or software.....???
I also appreciate that the market is splitting in personal/mulimedia devices and business smartphones like the TP2.
I would appreciate any comments from current users on their views/experience of the above.
Thanks,
Sam

Rhodium Video Performance?

I`m a Kaiser Owner, and looking at the Rhodium as a possible upgrade, but like many others here I`m sure, I`m concerned about iffy video performance. HTC really seem to have dropped the ball on this one, my experiences of the Kaisers video have made me wary.
Anyone heard any feedback on this topic? Anyone with a pre-production model give us a heads up?
For example, could the Rhodium play a 640*480 WMV video without dropping frames?
Same processor as the old TP must mean same video issues, right?
I had Kaiser, and with the right encoding & software video was absolutely fine! I don't know what all the complaints were about.
The Xperia can handle full resolution video pretty well if encoded correctly, and I'm sure this will be the case with the TP2 as well, as the hardware should be powerful enough to do it.
I can't comment on the Touch Pro, as I haven't used one. The TP2 has quite a high-res screen, but I'm sure it'll be fairly easy to get a decent video experience from it.

I think they made the drivers for the touch pro better didnt they? the 3d ones? so if they did yeah it will be VERY good if they do that for this to which I bet they will if they did for the old one
Won't be burned again!

To my knowledge nothing has been improved with the drivers for the touch pro. I have a Sprint TP and video sucks on it. Some ppl have messed around with 3d drivers with various levels of success, but nothing official has been done. There's a whole sticky thread at PPCGeeks on TP video playback tips:
http://forum.ppcgeeks.com/showthread.php?t=57282
So far I haven't really got anything to work for me reliably. What ppl fail to realize is that having a bigger/better screen is only going to make things worse if the hardware/drivers aren't improved. 320x200 video played fine on my Touch and probably would be fine on my TP, but going to 640x400 is 4x the resolution.
Unless HTC improves the 3d/video drivers, the TP2 is going to be as bad or worse than the TP because it is the same stinking hardware. I was so disappointed that the TP2 is just a rehashed TP which really has no better hardware than the Touch--just better screens w/o the greater horsepower to drive them.
I hope I am wrong about this and the TP2 video and graphics are awesome, but I certainly will not upgrade to it until I am certain the situation is improved.

Thanks for pointing that out. I am going to try them and they will probably help some, but I had already heard about it and for the most part they only address part of the problem.
If, and it's a BIG IF, HTC fully optimized ALL the drivers for the TP2, then it could be quite a bit better than the TP. Given HTC's crappy history I would have to have it thoroughly proven to me before I would believe it. However I am hoping against experience that it will be the case.
Maybe this is one of the big reasons why they stuck with much of the same hardware. So they could optimize everything. Hopefully.

Hello, I would have to say that the video quality is 100% better than the TP. I have been watching full videos with NO quality loss in sound or video. I was using the Sprint Touch Pro and was not very happy, but the TP2 is perfect. I can even get 2 full movies out of one charge!!! I have been watching a lot of DivX movies the same ones I watch on my PC, with no issues (well, except each one takes up about 700MB.)
The set up I have been using is, CorePlaer and the D3D Driver. DivX player works well also, but the text gets very small due to the resolution. Hope this helps!
Core player
Video quality is great with core player. Watched 2 movies on my TP2 today and it was very good with great frame rate. And I could use higher res mp4 movies if i wanted to and still keep 100% playback so i havent even pushed it yet. Totally recommended.
I can play a 800x480 AVC encoded movie with aac+ audio at ~1.2Mbit without any hiccups through HTC's video player. Coreplayer on the otherhand can't come anywhere near handling this. Looks damn good too! I used MEGUI with AVC Zune settings to make the video from a bluray movie. It's about 1GB in size.
curious
Just curious why the video player thats built in will play only some of my mp4 files? Thats one of the reasons why I went with coreplayer was because most of my mp4 movies would play a green screen with audio on the built in player and wmp.
Anyone know if TP2 has the same qtv video hardware acceleration?
I'm surprised nobody has posted anything about qtv.
http://forum.ppcgeeks.com/showthread.php?t=57282
I have a TP and mp4 video plays flawlessly through HTC album because it has the proper qtv drivers. My problem has been with playing divx in coreplayer with the reverse engineered qtv driver. I was hoping that HTC would drop qtv in the TP2 so that I could play divx in a player with proper video drivers. Does anyone know if HTC still uses qtv in the TP2?

MP4 is a file format that supports a few different video codec. Mostly like the green screen means the video codec isn't supported by the player. I would highly recommend these days to encode the video with H.264 as the video codec. This codec is the standard supported by all major companies these days, Apple, Adobe, MS, etc. Some video cameras like the Sanyo Xacti also captures video natively as MP4 (H.264) so there is no need to encode the video.
And TP2 plays MP4 (H.264) video well both in HTC Album and WMP.

Possibility of a ROM producing better 720p video?

Okay, so I know absolutely nothing about ROMs, so this is mostly a question of if this is possible:
Currently, the EVO's 720p video recording is lackluster. I find that the biggest reason for this is the bitrate of the video used. I imagine that the bitrate used on the video was to accommodate the included microSD card's Class 2 write speed.
Is it possible to increase the bitrate used for encoding of this video, to something ~5mbps, to which a Class 6 microSD could handle just fine? Ideally this could even be implemented as an option in the camera app, so that those who don't have/can't afford a class 6 microSD could still use the ROM.
If that is possible, what are the chances of having the video also record using a different audio codec? The current codec used is pretty much impossible to play back in anything except Quicktime (VLC's latest release candidate just added support, but it still sounds awful, like a pack of hyenas on top of the track). I'm really not particular on what audio codec is actually used; be it mp3, ogg, etc, as long as it's more easily played.
The best case scenario, the DREAM EVO ROM for camera capability for me, would be:
1. At least double the bitrate (4-5mbps) for the 720p video with an option to use old settings.
2. A better audio codec using higher quality settings (minimum 64kbps mp3/ogg/similar) that is playable in many more programs.
3. A more compatible container format like mp4/m4v.
Am I dreaming or would this be possible in a custom ROM?
Don't forget it will also be limited to how fast the hardware can encode the video. Someone with the right skills will have to push the hardware encoder to see how high they can push the bitrate without exceeding real time.

Yes, there might be hardware limitations, that's sort of what I'm asking; if this is something that can be "fixed" in a ROM or if we're stuck.
I think as long as it can handle the bandwidth though, I don't see why the chip would be incapable of higher bitrates. I'm not an expert on the matter, but I thought that the less compression/higher bitrate something is, the less power was required to make it happen.
well im pretty sure this is possible, if a dev puts the time and effort into such a large project. i only say this cause the nexus one recently got 720p video recording, something it didnt have from the start. and i think its known that htc made the video recording compressed, so i think theoretically if we lift this compression and use a different form of compression, we can get higher bitrates from the video.
Yeah, I'm hoping a developer can investigate this thoroughly. Even if it takes a while, it'd be nice to know someone is at least looking into it.
And to make it worth their while, I'd be more than willing to pitch some donation funds towards such a project when it becomes successful. I doubt I'd be the only one as well.
I was wondering this also. I'm not up on the technical aspects of this, but I was also wondering if the 720p could be improved through software fix/ROM development? I agree also that I'm sure a lot would be willing to donate for such a fix.
I'm sure eventually we will get a better cam, i mean look at the how the nexus got 720p video
You can easily get 720p at 60FPS... The snapdragon can support it.
i would most certainly donate for this improvment
yup i would donate as well
we just dont have as lively a development community as the nexus yet, but we will in time - we;re gaining momentum fast

Go look at the Nexus One forum... They've got up to 1080p capture.
Realistically though, it seems silly to rely on our phones to capture HD video. I have a G9 that does that task quite handily.
All I could find was 720p capture at 20fps and a max bitrate of 12Mb, which is plenty.
This is interesting, I'd like to see this happen as well.
I'll do what I can in terms of research.
Better low-light pictures too, if at all possible

Your 720 Experience

Hi I want to start this post so everyone can post their experience with the new 720 Recording Feature on the HTC Desire!
Please post Like this:

Rom used
I'll start:
http://www.youtube.com/watch?v=NxxPdPd8ea4
Description:
Me being very concentrated while playing the Drums... new song Bad Lighting hard sound situation (way too loud for this little Phone ) so worst case
Problems:
I see constant drops in FPS, or more likely a stuttering ever few seconds video playback just kida stops, audio is fine though! I did not have this Problems with other Roms so I think its not my SD card acting up?
FPS: 5-11 not very constant at all, although lighting was very constant (although very bad)
ROM used: LeeDroid 7.1b
Before official update:
http://www.youtube.com/watch?v=ugjI5ygsXzQ
Average/good lighting
20fps
Can't remember the rom, I think MCR v5, it was before the official update.
Not a lot of stuttering that I can notice, but the lens cover was a bit smudged and so the video came out a bit opaque.
After the update:
http://www.youtube.com/watch?v=S6KuPCn6_2M [quality should improve in a bit]
Probably a tad better lighting conditions
23fps
ieftm semi-stock rom
This is the best sample of three, one was ok, but the last one was stuttering quite a bit, as I think some background program was accessing the sd card heavily. Also lens here was a bit dirty
by the way, youtube quality doesn't render properly, linking videos should be better.

No, I think it was me that turned contrast a bit too high and the fact that without optical zoom or camera lens optics you can get lose details in the distance on such high resolution
I gave up 720p, it is not good. Jumpy, low fps and especially ****ty voice quality.
I use 480p, but it is also not good, not too jumpy ... still ****ty voice quality.
I have 2.2 rom from here and 720p keeps freezing every few seconds.
720p is ok for me. Is it possible that its to do with the internal memory available? I have 60mb or more free, I know some people are down to low numbers. my card is a class2 too. I think the clips look better played on the PC in VLC lpayer than when I upload them to youtube. I think youtube might be introducing some of the negative aspects seen... maybe?

720p is crap, its just upscale from lover res., dont use it.
more info:
The data rate of 720p is over 4 times greater than 800x480. 6000kb/sec versus 1200kb/sec. It's not purely upscaled at all. I made two sample videos of a page of text and compared.
There was ALOT more detail in the 720p video. Even when I zoomed up the 800x480 one. I agree it's not as good as "true 720 HD" but its certainly not 100% upscaled.

1200:6000 it's 5 times more. Yes it's not true 720 hd, but I can perfectly live with that quality if we get a couple of fps more
I've taken two short videos of a label, took screenshots from video player, cropped them, resized the 480 to fit the same size as the 720 one. It's very blurry compared to the normal 720p. See the hour in the fake pda, you can't read it in the upscaled one.
Video upscalers tend to do a better job than a simple photo resize and they do introduce more data leading to a larger file size. The disire may truly just upscale the video after all. In any case, its a shame that video capture on this device is as poor as it is. I dislike Apple and their iphone, but i'll give them this; all aspects of the software work very well from go and if not, a fix/upgrade is provided in a reasonably short time.

Given the current state of their last shiny toy, I think it's a bit funny to say so.
Anyway, I've done some more tests and I can take the screen captured from a 480 video and upscale it with any tool with best quality or other algorythms and you always end up with a lot less detail than 720p, especially when there is a lot of light (unlike that test above). I don't think the desire has the processing power to do a better upscale than what I'm trying and while there might be a bit of upscaling given you have a tiny lens, it's not all there.
Also any tiny lens without zoom is pointless when taking videos from the distance anyway.
I can only get 15-16 fps... anyone can do higher?
I can easily get 25 average, outside in. good lighting, with a class 6 sd

I talked to some iPhone engineers about how the iPhone can archive 30Fps ... its because all the decoding of pictures delivered by the camera is handled by the GPU... for Android its all done on the CPU! so we need to find a way to decode the video stream using the Desires GPU, but I think the iP4's GPU is far better than the Desires... i am a hardware engineer... i am in no way able to code anything like that! What Makes me curios is file size comparison between an iP4 and the Desire.
Also: Desire running a non sense rom (AOSP) just like the Nexus gives much better 720 Quality!!! so I guess its in the software

SInce I am NEITHER a hardware nor software engineer, I am useless here, other than to ask obvious questions. Your apple access to methodology of iP4's video capture is itself useful information -- something that if I were a software engineer working on the various test projects here at XDA, I would want to know. Maybe that's something they could infer, or maybe its published somewhere, or maybe it's one of those "Geez, it's so obvious do i really need to be told that?" points.
That then gets blurred and muddied by the REAL armchair knowitalls (*I* disclose that I know nothing) who pounce on a pronouncement by someone here and say "That's impossible, or that's bullcrap, look here at my image, it proves you wrong, end of story" -- only to often find --- NOT end of story and that person got it wrong.
All i know is -- my experience has told me never presume -- because this site is SO HUGE, it is actually quite often that the right hand doesn't know what left hand is up to.
I wish there were a better means of coordinating the total knowledge holders of XDA site on this 720p issue regarding TOTAL CAPABILITY, software and hardware, so there is 100% collaboration. In the end, there is only one answer: Yes, desire can meet or exceed iphone4 720 p in every measure of resolution, or not.

Which is bigger? what is your initial inference? larger file size = higher rez?
thank you
roufianos cooked a Rom that achieved 29-30 fps but the phone restarted after 50 seconds of recording. Was that due to overheating of the processor? I don't know. His phone gave up spirit and he is waiting for a replacement so the development of his Rom is on pause at the moment.

Ive managed 26fps @ 720p with my Desire running official unbranded 2.2. Im using a Class 4 card, so that might help over your Class 2.

I just compared the youtube clip to the original on my PC (i scaled the VLC window down to the same size as playing the youtube clip in its 'expanded' size) and there is definatly a small quality difference. The details on the original are noticable finer, so even @ 720p on youtube the bitrate must take a small hit.
Here is a screenshot of the comparison.

Just got my LX2. People confuse the extra features for inferior features as far as connectivity goes. Remember: it would be a blind, viewfinder-less, device that required you to return to a PC to manage content if it were not for the Bluetooth link to a smartphone. The quality if the streaming viewfinder is great compared to not having it at all! Though comparisons to bulletcams and action camcorders are inevitable, it's not at all the same thing. It can't perform it's unique function, being a wearable always-recording DVR that's built-in to your smartphone, if it was big enough to have a built in display/viewfinder or with a large enough battery to power it. I'll wear it to capture the things I didn't expect or intend to record, like the guy who forces my motorcycle off the road because he "didn't see me." I'll use a Contour or Go Pro if I want to do any moto-vlogging in higher quality.

High-Quality Audio Recording

I have a question for the developers (im not one):
Though the KF doesnt have a built-in mic, it supports an external one for audio recording. Ive been using Android devices for a little over two years, and have tried a number of audio recoring apps on them.
There are a number of stereo microphones available (from Belkin, Tascam, Blue, etc) that allow high-quality stereo recording on ipods and iphones. There are a number of apps available for recording on Android, but the quality of the recordings is not great. Why is that? Is there something inherent in the Android platform that does not permit hi quality recording?

This link might enlighten you a bit. Along with extremely poor audio-latency it would seem that audio recording is also problematic. Strange to find this in an audio device such as a phone eh?
Thanks; I actually used to use the Rehearsal Assistant app. I posed this same question to the developer of J4T, which is a very cool Android multitrack recording app, and I just got his response:
"One reason might be that the best recording quality that is supported by most Android phones is mono, 16-bit pcm, with samplerate 44100. So to make sure a recording app runs on most most android phones, the developer should probably use those numbers and not go any higher.
But it also means it's possible to have android phones that can record at much higher quality, and maybe they are out there. But that capacity may go unused, because the apps are developed for the 'average' phone.
Perhaps on other platforms the 'average phones' have higher bitrates and samplerates.
There are actually 2 ways to do audio recording on Android, but I'm not familiar with the other way (where you can record to AAC or AMR format). Perhaps the quality using those codecs is better than PCM, I don't know.
Please don't take this as a definite answer - this is just a guess from my perspective, maybe a manufacturer (or the Android team) would give a different answer."
I've been using a Belkin Tundtalk stereo microphone with a 3rd-generation ipod nano to make reharsal recordings of my rock band; the quality is actually very good. It records in wav format, stereo, 16-bit pcm, with samplerate 44100. So, outside of the fact that Android records in mono, not stereo, the potential for decent quality is there. The lousy quality must have a lot to do with the cheesy microphones used in the Android phones. If I could find a decent quality mic that would work with my Android phone (or with the Fire), I imagine it would make a big difference.
Yeah, from what I know about Android audio going the other way, the audio-latency issues, Google really managed to screw up on a bunch of levels. The audio app market on the iPhone is pretty big and they just haven't stepped up to the plate for developers from what I can see. I see a few apps coming out like AudioSketch that claim to have custom low-latency audio drivers, but that one isn't available for the Kindle Fire so I really can't say. But, sorry, I am digressing. I'd be curious as to see what results you get from your experiences.

This man doesn't now a thing about sound encoding. PCM is uncompressed audio format so it have smallest use of CPU and it has best quality. Only problem is that is space-hungry in comparison with other codec's.
In audio, whole system is good as the weakest thing in it. You need good MIC, you need good MIC input, you need good audio driver and you need good recording app. If one link in this chain is inadequate resulting sound quality is on level of that poor part.
Hey, just a thought but you might be able to turn your question into a free Kindle Fire if you were so inclined.

Now that you've brought it to my attention, I AM so inclined! That's for letting me know.
I posted my question there, and after about an hour it was Closed as "not constructive" lol.
As I said, I'm not a developer. Even before I posted the question here I googled the subject and haven't been able to come up with a definitive answer as to why this is so. I would think there would be a huge market for after-market microphones for people to use on their Android phones (as there is for iphone and ipod). If I was an iphone fanboy, this would be my first argument against Android - crappy audio recording!
