CRACKED H.264 VGA video recording with excellent quality! [Tested on Touch pro2]

First, as you all known, Touch pro2 can't record VGA video in H.264 format(the resolution is limited to 352x288), it's really a pity. And if you want a VGA res, you just can use a MPEG4 format and finally get a video full of noise and blocks...... After I buy my Touch Pro2, I always try to find a way to enhance the video recording quality. And finally found it!
If you have the software "BsB tweaks" in your ROM, you can see it has such two tweaks：
Video Format--Enable hidden video recording format
(Add H.264, Motion JPEG,3GPP2 to the format list)
Video BitRate--Improves Video recording in MPEG4
I should tell you that, this two tweaks is not useful on Touch Pro2 (I don't know if they have any effects on other phones).The first one makes you could record in H.264 format, but only with a resolution up to 352x288. The second one has no use at all.
But from BsB tweaks, I know that there're some Reg keys handle the video recording parameters, So I spend whole night on these keys, and find many interesting things
1.Enlarge video recording Bitrate and Framerate:
Value function
"HKLM\SOFTWARE\HTC\Camera\Recparam\<...>\<Bitrate;VSBitRate;FrameRate>"
These Reg Values control the video recording Bitrate and FrameRate, if you want to enhance the quality, you can write down a bigger number.
For example, change
"HKLM\...\Recparam\H264Large\BitRate" to 600000(dec)
"HKLM\...\Recparam\H264Large\VSBitRate" to 600000(dec)
"HKLM\...\Recparam\H264Large\FrameRate" to 20(dec)
(Tips: Large equals to CIF, Medium equals to QVGA, etc...)
then when you set the Capture format to H.264 and Resolution to CIF(352x288),finally you will get a *.3gp video at 600kbps(VBR)@20fps.
Now a new question comes out: what's the upper limit Bitrate of Touch pro2 to record a H264 video?
I have done the test and find out that you could record a H.264 video as high as [email protected](352x288) ! Maybe you have thought that MSM7200 couldn't be so powerful to encode 1000kbps H.264, but it really works fine！
So，if MSM7200 could support 1000kpbs bitrate，then it should have enough power to record a VGA H.264 video! Go next！
2.Crack H.264 VGA video record limitation on Touch Pro2:
Don't wasting time on the HTC video recording program, whatever you do finally you just can use the resolution no more than CIF(352x288) when H.264 format is selected.
Now the way out is here:"HKLM\SOFTWARE\HTC\Camera\P2\"
When I delete it, the HTC video recording program can't start anymore. Now you know, this Reg Key has the Values to decide which format and resolution the recording program should use
Value function
"HKLM\SOFTWARE\HTC\Camera\P2\CaptureFormat"
When set to "10(hex)", the video format is MPEG4 (*.mp4 V:MPEG4, A:AAC);
When set to "2000(hex)", the video format is H.264 (*.3gp V:H.264, A:AAC);
Other value not tested.
"HKLM\SOFTWARE\HTC\Camera\P2\MainCamCaptSize"
When set to "20(hex)", the video resolution is 352x288;
When set to "1000(hex)", the video resolution is 640x480;
Other value not tested.
PS: Check if there is a Key "H264VGA" in "HKLM\SOFTWARE\HTC\Camera\Recparam\", if you can't find it, please create it manually and copy all Values from "H264Large", set BitRate & VSBitRate to 1000000(dec) and FrameRate to 20(dec).
When you set CaptureFormat=2000(hex) and MainCamCaptSize=1000(hex),then start HTC Video Recording, you'll get a VGA H.264 video with great quality!
3.Try 1000kbps VGA MPEG4 video recording:
Besides H.264 format, you can also enlarge the BitRate (in HKLM\...\Recparam\MPEG4VGA) of MPEG4 formate to get a excellent quality MPEG4 video.
Compare between MPEG4(1000kbps,VGA,20fps) and H.264(1000kbps,VGA,20fps), I find that MPEG4 has a better quality on rapid motional scene, because it's variable bitrate is up to 1600kbps, and H.264 is limited to 1000kbps. MPEG4 also has a higher average famerate, act more smooth than H.264. On the other hand, H.264 has a strong advantage on slow motional scene. Altogether, MPEG4 has a surprising better quality than H.264 at 1000kbps VGA mode.
4.Attention:
1.Don't set the bitrate more than 1000000, if you set it as 1100000, you could find that the actual bitrate break down to 128kbps! That is why the BsB tweaks didn't work, it tweaks the MP4VGA bitrate to 4194304(dec) !
2.Don't set the framerate more than 20, or you'll get a less framerate.
3.MSM7200 handles MPEG4 and H.264 recording in HW mode, so lowering the bitrate is useless to get a smoother video. You just need to keep the bitrate less than 1000kpbs then MSM7200 will work best enough.
4.When you decide to record a VGA H.264 video, a overclock is recommonded. Just use WiMoSpeed to oc to 710MHz!
5.Don't open HTC Camera's setting panel in video recording mode, that will lock the H.264 VGA mode again and the resolution goes back to CIF!
6.Only tested on T-Mobile Touch Pro2 with EnergeRom, other MSM7200/7201 phones should work too.
===========================
Cab and Reg files for this topic:
Enable MPEG4 & H.264 VGA recording at 1000kbps: MSM7200_H264VGA_Tweaks.cab
Unlock the H.264 VGA limitation: vgaunlock.reg (included in MSM7200_H264VGA_Tweaks.cab, but if you click out the HTC Camera's setting panel and the resolution go back to 352x288, you may need it to turn on VGA again.)

I have never been able to record in H.264 or MOTION JPEG. I can select them but everytime I wanna record my phone freezes. It has been this way no matter which rom I use. How do I get these two formats workin? Is it common for for these formats not to work?

OC to 768MHz？ I think this is too high for your phone, MSM7200 use HW mode to encode video, It's video DSP maybe unstable even while your CPU works fine.
If you have tried without OC, I would say that your phone really need a repair
And you could depress the clock lower than 518MHz,for example:400MHz then try again, maybe it works.
PS: Did you try EnergyROM?

Thanks!!! could you please post some video tests on YouTube?

I really want to do this, but there is a Great FireWall in my country which makes us can't visit YouTube, Twitter or Facebook, because there're many "disharmonious" information on such sites and we're "protected" by the Goverment...
But I could show you two video captures(my Laptop's desktop),left one on H.264 and right one on MPEG4, both has a 640x480 resolution and the bitrate as high as 1000kbps, I promise there're video's captures but not photos

From day 1 the hidden formats have never worked. I use BSB TWEAKS to show them but they just freeze my camcorder. This happens whether i am overclocking or not. Yes i have tried ENERGY roms but still nothing. Could I be doing something wrong with BSB TWEAKS? I ask because my friend has the same settings and these formats do not work on her device either. It would be great if I had the reg entries for HKLM/SOFTWARE/HTC/CAMERA so I could compare them to my registry.

Oh, the Default format of HTC Camera really sucks, here is my Camera.reg, pls flash the newest EnergyROM and import it then try again.
By the way, what's the version of your TP2? Mine is T-Mobile without the front Camera, maybe there is something wrong with your front camera Reg setting.
Check the Value "2ndCamCaptSize" under "HKEY_LOCAL_MACHINE\SOFTWARE\HTC\Camera\P2", try set it as 10(hex) or 20(hex).
Or hard reset your TP2, then only change the value "HKEY_LOCAL_MACHINE\SOFTWARE\HTC\Camera\P2\EncodeFormat" to 7FFFFFFF(hex), which add H.264, Motion JPEG and 3GPP2 to you format list (do not use BsB tweaks), and try again.
And, if you really can't use H.264 whatever you do, why not try a 1000kbps MPEG4, it has even better quality that H.264 in VGA mode.

So... what's the way to go?
install the CABs, do the reg edits, both?

Just install the CAB that's OK.
And you could also do the reg edits if you want to adjust the recording parameters yourself
The vgaunlock.reg is used to set the recording format back to H.264 VGA when you:
1.want to try another format (for example, MPEG4), then you want to use H.264 again;
2.click out the HTC Video Recorder's setting panel by mistake, this would pull down the H.264 recording resolution to 352x288.

AAC enable in Froyo?

Hi all,
Is there any way to get AAC encoding working in Froyo? So it can be used for video recording?

AAC stands for 'Advanced Audio Codec' and it is used to encode the audio stream in Froyo too. The bad news is that the codec settings in 2.2 where pushed too low and that's the reason the sound in video clips to be such low quality. I don't think that there is a way of changing the settings.

According to the media_profiles.xml file in system/bin, video recording actually uses amrnb codec for audio, which is a terribly low quality sound. From what I have been able to find out so far, AAC isn't actually enabled in Froyo at all. I tried editing the media_profiles file to enable AAC for video but it doesn't seem to make any difference...

This is what MediaInfo says about a video I shot while Gingerbread wasn't released yet.

As you can see both the bitrate and the sample rate are higher which results in better quality, but the codec is virtaly the same.

You're right
Thanks for that tkolev - very interesting. I guess I should have checked that myself first. You're quite right, it is indeed very low quality AAC.
So question is, how to change the AAC encoding settings in Froyo. Doesn't seem to be in that media profiles file, because AAC encoding isn't even mentioned in there...

I don't think you can do that. Upgrade to GB is the only way I know of to get better sound in videos.
EDIT: Actually the stupidity of limiting the sample rate to 8 khz led me to believe that HTC used a microphone with a very low frequency response because that's the only logical reason they might have in using such low settings. Fortunately this is not the case.

LGCamera
Just as an update to this. I found the solution to the sound quality problem in video in froyo roms. A camera app called LGCamera. You can set everything the way you want it, including bitrate for the video, and file format (eg MP4 rather than 3gp), and also crucially AAC sample rate and bitrate for audio. Very nice. Video quality seems to be at least as good as stock app, possibly slightly better. This is at 8mb bitrate, haven't tried the higher bitrates yet....

does aac work on lgcamera on froyo?

[Q] Playing MKV 720p Movies

Hi All,
Tried to play MKV 720p files at my Desire HD but i have some problems
1 - Can't find MKV Files in Video The defult player for the device
2 - VPlayer Is so lagy and can't watch the video
3 - RockPlayer Works Only Smoothly With Hardware Decoding but No Sound !!
4 - QQPlayer Same as VPlayer
5 - mVideoPlayer Can't run MKV !!
Any idea how to solve this and play MKV 720p files smoothly without convert it ?!

It isn't possible thanks to HTCs crappx video drivers.

Same Problem With MP4 720p
So I Have To Convert All To Avi to get it works good

Dice player or Moboplayer you could try.

Its the same with all players. Some use software decoding (cpu renders, vplayer, rockplayer, mobo, ...) or hardware decoding (gpu renders, stock video player, rockplayer, mobo, ...)
They all use the same methode to decode a video so there won't be significant improvements as long as there are no good drivers/codecs for it.

Any suggestion to get both audio and Arabic subtitle ?!

Hellooooooooooo
Sent from my Desire HD using XDA App

Okay, here's some suggestion for now:
[*] For the audio problem, try DicePlayer and then;
[*] Same way you encode the srt into Unicode, or US-ASCII, or ISO 8859-6 and set the player subtitle encoding accordingly (if diceplayer doesn't read your current sub).
[*] Wait for updates of Soulmovie player.
It is worth doing a little extra job to enjoy the whole movie doesn't it?

Probably not what you want to hear, but you'll save yourself a LOT of aggro by encoding it to something more usable, or downloading it as such.

convert it to mkv, play with stock vid player

BS Player seems to do better with files it has to use the SW renderer on than MX player in my experience, you can try that to see if it helps at all.

Thanks for the tip. BS Player was much better than MX player. I had no need to encode again.

[Q] 4k - UHD video playback on SGTS

Hi everybody,
I have a question.... I have a Galaxy Note 3 and I have recorded some videos in 4k to see how they work on my new Galaxy tab S
but the stock video player can't open these videos and the only player on the market that runs these videos is MX player but the video frame rate is poor and the audio is out of sync....
Could you tell me a video player or a way to convert UHD video from my Note 3 to the Galaxy Tab S ?
Thanks

SGTS can neither record nor play 4k videos as its not a 4k tablet.

The SGTS can't record UHD and It can't play 1:1 4K video ... and this is obvious because its screen is not UHD ... but My question was:
There is a way to play smoothly UHD video with this tablet? with a specific player or with a converter (pc side)

How does that work then? My Note 3 is not UHD and it plays the 4k videos it records just fine, at a lower resolution obviously

"it doesn't play 1:1 4K" means exactly what you have wrote... The display of Note 3 is "only" Full Hd ..and the SGN3 downscales the UHD content to the native panel resolution... I think... or I Wish that SGST could use the same way with 4K / UHD videos... but till today the only player that runs UHD video on SGTS is MX player but the video aren't smooth..

UHD Videos...
The UHD Videos from my S5 worked on my Tab Pro 8.4 but don't work on my Tab S 8.4..... I'm starting to like this tablet less and less..

Before I open a thread with the exact same question I give this one a bump. Spoiler: I managed to play 4k video with Samsung Galaxy Tab S 10.5 chagallwifi T800 with downloaded 4k video samples.
I've recently tried several custom ROMS, some MM, some Nougat to figure out differences. I use mx player, bs player and a noname videoplayer (com.ab.videoplayer). VLC player performed poorly with all ROMs so i'm not using it. The players behave differently. While mx+bs players are somewhat identical (dropping videoframes while playing audio correct), the noname video player drops video frames (stutter) but plays audio correctly.
The source video+audio codec also matters. Only some UHD material plays spotless while the size of the media stream is comparable. I was able to audit + tweak CPU+GPU performance to max with deadly audiutor. Tweaking would not make much difference. I observed CPU+GPU would not stress to 100% even without tweaking. So what would be the reason for dropping frames in audio or video? In the windows world I would look for the codecs the material was coded in and search for a capable player. In android the functionality of players is not so well documented. So maybe the wise can figure, what the reason for poor 4k performance is or rather give tips how to avoid it.

I could not find info doing a search for 4k nor UHD in https://forum.xda-developers.com/galaxy-tab-s. Thanx in advance for helping out.
