I am planning on getting a Sprint Galaxy Nexus (have too many unused upgrade lines lol). And I was wondering how it performs on 720p 10bit video. From what I read it is able to play on MX Player, BS Player, Dice Player but I am more worried about performance. Some devices I hear have issues playing 10bit high action scenes so I want to know how it does. And if anyone has any experience with this?
I don't know but the nexus decodes 1080p video at the hardware level due to its chipset, not software like many phones. So it handles video playback like a champ.

I don't think any phone can do hardware decoding of 10bit video. 8bit video even a 1ghz single core hummingbird can play back 1080p with hardware decoding. But I am more particularly interested in 10bit which is more then likely decoded via software.

Can you point someone to where they can download a 10bit video and test it for you? (Maybe just a short clip?)

try vlc beta or mx player. H/W decoding might not work with these files but software playback could be fine in theory.
MX Player can decode 720p 10-bit (Hi10P) files using its software decoder but it's very slow. You'd better off reencoding them using Handbrake.
PS: Even without action scenes, 10-bit files lag on the GNex.

Well I am able to play back 10bit 720p on my Droid Charge so as far as playback it should be able to do it, the problem is performance. the droid charge isn't powerful enough unfortunately.

Well if I am going to transcode then it kind of eliminates some of the purpose. Have you tried in MX Player to set it to use both cores? fast mode? 16 bit color depth? overclocking the phone? None of the above would help?
10-bit H.264 is pointless. The screen (most likely 6-bits per channel with dithering) can't even display that many colors.

There are other benefits to 10-bit. The compression gives higher quality and smaller file sizes. Also the screens last I checked are not crappy TN panels. Super AMOLED is more then capable of displaying all colors. Even the IPS screens on phone these days are Super IPS (not to be confused with eIPS) and should be capable of displaying 10bit color.
That the format of the video is what it is and transcoding is not an option. Hence why I am interested in performance.
Don't expect anything but horrible performance. 10-bit H.264 streams can't be hardware decoded by anything on the market and probably never will.
Most S-IPS panels are also 6-bit per channel with dithering. Very few are actually 8-bit. Now, as far as monitors go, unless you're willing to spend 10 times the price for a non-consumer model, you will not find anything that supports 10-bits per channel natively. The story holds true for phones, too. I don't believe there are any 10-bit screens and I'm sure there won't be any for years to come (again, unless you're spending thousands for a phone).

First of all Super AMOLED has full color support because its not an LCD. The only thing you need to do is calibrate the screen so its not saturated. If you take OLED decay asside OLED can give you perfect color reproduction batter then the best IPS screens. Of course overall 10bit ends up being converted to 8bit because the hardware needs to support it like ATI Firepro
Now for SIPS, name me one monitor that is 6bit. The low end monitors that are 6bit are eIPS which use FRC. S-IPS is at minimum 8bit.
But we are getting off topic here..all I want to do is playback 10bit content. I am well aware of the limitations and that the decoding will be software which goes back to my question. Is the nexus powerful enough for the job.
Just tried one of the sample vids with MX and VLC. VLC was stuck on the first frame and MX played it but what seemed like 1FPS. I overclocked my phone to 1812MHz and have FrancoKernel with 512MHz GPU. Set my governor to performance and still no go. Tweaked settings on MX and still no go.
Sorry OP but I'm pretty sure the GNex can't play it.

With those Specs sounds like you're trying to cook your phone lol. Higher isn't always better. Example, I installed Batman to my Transformer which was overclocked to 1400mhz and it lagged like crazy. Once I put it down to 1100 it ran a lot better. Maybe you might have to find the sweet spot for your phone.

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.

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.
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
All the video samples from the G2 I have seen on Youtube so far have not been impressive. Most disturbing about these videos is the sound quality, it is pretty bad. I have a Nexus One (hacked with Cyanogenmod's 720p recording feature) and it also isn't that great so I'm guessing this is a 'feature' of HTC phones. Compared to the Galaxy S (from Samsung) the HTC phones (G2, N1 and even the EVO) seem to suck in the video / audio department.
In a recent post I read that the audio codec for a HD recording off the G2 is this:
AMR (samr), Mono, 8k, 32 bits per sample
Could this be the problem and can this be changed?
AMR == Adaptive Multi-Rate Audio Codec. Dunno what the "s" in "samr" is all about tho.
I see a comparison with the nokia 8 and there is a definite sound quality difference. (Be sure to watch this in 720p)
Wonder if the sample rate is adjustable by firmware/settings or if it's set in hardware. Strangely wikipedia lists 14 modes, none of which are at the "8k" (rate?) you reported... I see AMR_7.95 tho.
Anyway, my g2 is on the way....

Idle thought- I wonder if the codec is set to a low bandwidth to accommodate slower SD card speeds. I think the g2 comes with a class 2, and this thread suggests that there is stuttering when playing back at the HD setting.
This is just idle speculation.

Agreed. Audio isn't stellar and playback has stuttering. In fact, I've already experienced a weird situation where the video wouldn't actually play - just showed a blank screen with the audio playing.

One more thought... This is an old issue. If you doubt the potential the video camera COULD have, take a look at this audio comparison linked from the thread. At least on the n1, the microphone is capable of way better sound than the camera app currently offers. The g2 has a faster processor-- it should be able to encode better sound.. AAC? Ogg?
Update: It's not the camera app's fault. It's Android's. There is an open issue for this. It looks like Android itself doesn't support anything better. The good news is this isn't a hardware limitation. As someone suggested, a WebM encoder seems like an obvious thing to add.

I just starred the issue (they look at that don't they?)... I recorded some video at a concert last night and while the video wasn't terrible, the sound is absolutely unbearable. Makes the videos pretty much worthless
I keep wondering if it's possible to stuff our own codec in there. I mean, some of the android phones have higher quality audio, right? If so, how do they do it? Why are those codecs commented out in the video camera code for...?
Doesn't cyanogenmod have FLAC support? Couldn't other codecs be added to the phone app, even if they're in java?
You're right, the current audio situation sucks.
Okay, so I have been watching videos from the full YouTube site and they work perfectly on 720p. When I play the videos on 1080p, the videos lags, giving me something like 1 FPS.

I just checked it myself. I have the same problem. Maybe the device doesn't support 1080p playback. Which is odd, I thought it recorded in 1080p.
1920x1080 runs just fine on mine

YouTube 1080p runs in flash..what's you expect..also..why in the world would you watch a 1080p video on a 480p screen?
Try a different browser

Before we had root in the first days of the sgs2, i was able to watch 1080 videos wonderufully on YT also, epicmealtime fyi. I tried it today and the stock browser lags. =/
Why? Why do you need to see 1080P videos on a screen that only does 480P? And of course it'll lag it's running on flash on a website not optimized for mobile. Geez this is a phone not a desktop gaming rig.
It's not your phone it's youtube it's self. Youtube has always lagged on 1080p videos. My desktop has problems with it and I have 8 gig ram. Intel i7 sandy bridge with AMD Radeon HD 6990. Ever since youtube upgraded their interface it has been plagued with problems. My connection is 20 down 5 up.
The phone can run hi 10bit 1080p blue ray h.264 mkv videos with the lowest and highest encode possible with out losing frames. Which looks better than anything you can possibly stream. There is nothing on youtube worth watching in 1080p most videos are upscaled anyway. Which really isn't 1080p anyway.

I watch 1080p videos because they look much clearer and less grainy than both 720p and 420p. I have tried different browsers but the same problem arises.

I think you need a quad core processer in order to watch 1080p videos.., my tab 10.1 can`t play 1080p videos...... it has the screen for it which leads me to believe it`s the processer

that's your brain talking.
I bet if I had 3 identical gsIIs one displaying 480 video, 720, and 1080 you wouldn't be able to pick which one is which.

I think many of us are spec whores because we want a mobile desktop experience/replacement/all-in-one mega device and I don't think you picked up your GS2 without thinking the same.
I bet i could jesse james. How bout you run a vid on all three options and take a screenie and post. Im not looking to start something, i just want to prove a point

Never mind. My logic was wrong but I watch CoD vids mostly so I can only tell the difference in such videos. But i hope you get my point. I want to maximize my phone's use.

Hi, does Xiaomi Redmi Note 5 Pro (Snapdragon 636) support hardware decoding H.265 10bit videos ?
thanks.
Yes it does.
Sure ? for a video 10bit ?
Because a Snapdragon 625 can't play HEVC 10bit video with HW decode.
ARM CPUs doesn't support hardware decoding of HEVC files. You will have to rely on software decoding.
Be careful with what you say. Technically no CPU does hardware decode of video VPUs take care of that (and GPUs but sometimes the VPU is included in the GPU as a separate sector). SoCs do hardware decode of hevc.
The Qualcomm flagship SoCs have had ten bit hardware decode since the 820. Mediatek had it on many of its chips, both flagship and mid-range (and I think low-range too) but not all of them and they stopped advertising which ones do and which don't. Kirin 960 doesn't but I don't know if the 970 does.
The mid-range Qualcomm chips are confusing. The 625 and 650 don't but the 660 does. So it should be safe to assume that anything newer above the 660 does but who knows about newer chips that are lower on the spectrum.
I know this does not answer whether the 636 supports it but it does show it's possible and we should wait for someone who can actually test it.

Yes, it is capable to. I have tried Jellyfish video, 120 Mbps 4K UHD HEVC 10 bit. This is a super deadly combo. SD636 plays it smoothly using H/W or H/W+ decoder in MX Player (1.9.24). At the 140 Mbps 4K UHD HEVC 10 bit with TrueHD 5.1 sound, only H/W+, H/W not supported (seems missing audio codec). As long as one decoder works, it is playable.
At SD625 (RN4), even the lowest 3 Mbps HD HEVC 10 bit video there, already lag and dropped to S/W, can't decode in H/W nor H/W+. This is also something that SD820 can't do in its time. SD820 is capable (hardware), but a lot of vendor messed it up and don't put the proper software/codec to decode it.
In SD636, finally we have the hardware and software/codec enough to basically decode any video. (I haven't tried 4:4:4 video though) It should hold up for quite long until the new video standard (AV1) becomes mainstream. And by that time, you probably have upgraded to newer phone.
Additional info :
Same 120 Mbps video, switch to S/W, immediately black screen. So the VPU/DSP is powerful enough, but the CPU is not capable to pull the 4K. But S/W still can play 90 Mbps FHD HEVC 10 bit, not smooth though. And you don't want to play video using S/W, it will kill your CPU and battery. (At my previous phone test, H/W or H/W+ gives 8 hours but S/W only 3 hours playtime.) I don't try any bitrate above that, since we rarely have content with such a very high bitrate. At that kind of bitrate, we would run out of storage first. (30 seconds video already 500 MB; 2 hours movie will be 120 GB!!!)
Other RN5 users are welcomed to do the test. To get the sense on whether it is smooth or lag, try the same video at other SD625/SD820 phone. Or at RN5, try FHD video below 90 Mbps and switch to S/W decoder. Other SD636 phone should be capable the same, but I only tried at RN5.
