Video Encoder - Sound in sync??

I spend quite a lot of time travelling, and find my HD2 has an ideal sized screen for watching films on when on the move.
Previously I had the Touch HD - which was also great.
I've been using a program which I found on here called MP4forHD - which works great - but all the videos are slightly out of sync. I'm processing them on a quad core 2.83ghz PC with 8gb or RAM, so I don't think its the PC thats the problem. When I check them on my PC once they've converted - they're already out of sync - so its not the phone.
The program converts directly from a DVD or file - which is exactly what I want.
Prior to MP4forHD, I was using another tool I found on here which was just called Encoder. It only did files, so I had to use DVD Decryptor, then VOB joiner to make a file that it could re-encode. I've tried it just now, and its also out of sync.
Both these programs have a setting for HTC Touch HD - so they encode at the correct resolution. I've tried fiddling with settings, but no matter what I do, it always seems to be out of sync.
What programs are folk using to get a good video file - and what settings? I'm away tomorrow morning on holiday and have a pile of out of sync films to watch! I hope I can get some suggestions so that I can re-encode a couple of them to be in sync
Cheers...

I just use the standard Manilla player as its the only one that utilises the GFX chip on the phone. I do have Core Player, but it doesn't play the movies any better.

I've just been hunting through Core Players advanced options and realised that there is an A/V offset - which if I set it to about -0.3 seconds works perfectly!
Ideally I'd still like the films encoded in sync, so if anyone has any magical programs / untilites then please let me know. At least I'll manage to watch in Core Player in sync on my flight tomorrow

I use avidemux, which is good because it has lots of options and is free. I hear handbrake also works well, and microsoft even has their own, which worked well for me the one time I've used it
Microsoft Expression Encoder: http://www.microsoft.com/Expression/products/Encoder_Overview.aspx

Handbrake: http://handbrake.fr/
On a side note: If you have the time, could you see how high you can get the bitrate on a h.264 WVGA video before it starts stuttering?

android .amr audio format probs ...

Just noticed (taken me 3 days) that my desire seems to record all audio in .amr format. This is fine on the device but as soon as it goes anywhere else there are problems.
The stock voice recorder does what i need quite well - but it records in amr format so although the "share" option makes it easy as pie to email someone a voice note, chances are they're not going to be able to open in at their end.
Same seems to be true for Evernote - I record a voice note but I can't listen to it on my PC. Opening a voice note through their web interface (firefox/win7 32) requires a plugin that cannot be found and installing their desktop software doesn't help either - it won't play any audio files.
Am I missing something fundamental here?
Know a good audio note app that records in MP3 or WAV with an easy "share" feature?
With evernote, how do you listen to audio notes on your PC?
Many Thanks, M

Loads on media players can play .amr, even if it is a slightly annoying format to be recording in. It is, however, the standard format for mobile phone recording since it's good at recording speech.
VLC will play it, so will Media Player Classic these are pretty standard audio players.
If you want to convert the files just shove 'amr to mp3' into google, there are loads of converters (some open source).
Probably the best bet is to use Audacity (free audio editor) and ffmpeg (codecs) to open and re-encode files. You can also edit the files to your liking (remove noise etc.)

Well that may be the view from the leading edge but NONE of the 12 people I sent audio notes to (before I realised they were recording as amr) were able to open them and they're certainly not going to download a 3rd party app to accommodate me.
And I certainly don't want to bugger about with transcoding on the desktop - I want to share straight from my mobile - but I can't find a single app that does something as simple as record to an MP3 file on Android. Any suggestions?
While there is a lot to love about this device / platform I am becoming increasingly aware of this sort of niggle as I scratch the surface.

Recordoid allows you to choose a few options like the format (between .3gp and. wav). I tend to use the app as a dictaphone. It has no sharing options though but I found it best for my purpose.

Thanks for the tip - will give it a go.
If I can get a wav or mp3 to a directory I can set up an Astro shortcut to it that will make sharing easy enough.

Well, I can only offer some notes from a different usage;
Recordoid records to /sdcard/dictaphone/ both through the widget and the app in .3GP and .WAV
HiFiCorder records to /sdcard/HiFiRecordings/ in .MP3 and .OGG (including very high quality)
Rehearsal Assistant records to /sdcard/urbanstew.RehearsalAssistant// in .3GP and .WAV
Virtual Recorder records to /sdcard/VirtualRecorder/ in .PCM
Voice Recorder (by Mamoru Tokashiki) records to /sdcard/com.tokasiki.android.voicerecorder/ in .3GP
Simple Note records to /sdcard/simplenote/ in .3GP
VoiceTask records to /sdcard/VoiceTask/ in .AMR
Voice Recorder [default] records to /sdcard/My Documents/My Recordings/ in .AMR
Most of them if not all feature options directly in the app to send through mail. Try them and see which suits you best. They are each positioned for slightly different uses.

VoiceTask - send your recording via mail in MP3 format
VoiceTask - application is a simple and handy voice recorder with possibility of sending recordings to any E-mail inbox in MP3 format. Application is designed for easy summarization of phone conversations and any other audio recordings.
The app is recording in the .amr format, but when you send the recording to mail, it is transocded into MP3.
Files are send to one email address (which you input on setup - no additional configurations needed).
And best of all... App is FREE!

Interesting, thanks - will take a look ..
Your app I presume?

I think it has potential - UI not too responsive (took me a few taps to start/stop recording).
Really needs some options on quality setting (as default is poor) and as some some else has commented I would prefer it to exit cleanly rather than running in background.

VoiceTask 1.1 (bugfixes, sending to multiple addresses) is out!!

Yes, I am developer of that app...
On my phone responsiveness is o.k.
Application doesn't exit cleanly like you said... This thing could be fixed..
I hope I'll have time to fix this until next release...

Thanks for the details, will test.

[Q] ROM with working h.264 playback

Can anyone tell me which ROM out there has working h.264 playback other than the original AT&T Tilt 2 ROM? Depending on the encoding program I use, I either get no audio or no video.
I've posted on this a dozen times, but no one has a fix. I've tried the latest Energy ROMs (start menu up top) and the new AT&T ROM, but no go. I've even put a trouble ticket in with HTC (they say it's not a known issue, but are looking into it).
Before you blame my phone or my videos, I've got a Tilt 2 and a T-Mobile Touch Pro 2. Both show the same problem. If I take the very same videos, that don't work on my Tilt 2 with Energy or the latest AT&T ROM, and downgrade to the original ROM, they work! Also, the videos play with
I'm hoping someone knows of a ROM based on a working ROM that I can load on both my AT&T Tilt 2 and T-Mobile Touch Pro 2.

You need 3 .dll files from the original Tilt2 ROM to make it work.
qccmquery.dll
QTV.dll
qtv_mp4_decoder.dll
I don't know for sure that you have to have all 3 of the files, but I do know it works if you do have all 3.

Where should they be placed (in what folder)?

I tried placing them in the \Windows folder. I rebooted and now I have audio, but no video. So close, but yet so far. Any other suggestions?

Yes, they go in the Windows folder. You may have to use Total Comander or something like that in order to actually overwite the ROM files and you will probably have to do a soft reset after placing the files on the device.
Also, I just use the Full screen player to view the videos. I don't use WPM or anything like that, but the other players should work also.

Yup. I used Total Commander and did a Soft Rest. I'm just using the HTC player, and now no video on any of the h.264 videos, but sound. Before I had some with video and no sound and some with sound and no video.
I've looked around and found a few different versions of those files, also some references to htcmdp.dll, so I'll try swapping a couple of them in.
Also, what ROM are you using. I like the Energy ROMs, but I'm not married to them, so if yours works...

It's my own home brew.

All the ROMs that I have used so far, from the original Telstra stock ROM to the my current Energy 21907 ROM all played mp4 (H.264 and AAC) video files correctly. Frame rate may not be ideal depending on the bitrate and file sizes. But at least they play without me having to do anything.

Which ROM specifically? I'll load it today. I'm currently using the August 25th, 21914 Sense 2.5 ROM. I'm not a big fan of the Cookie Home Tab, but if it works, I'll give it a shot.
Also, what player are you using? TCPMP works for the h.264 videos, but really jerky. Windows Mobile and the HTC player used to be perfectly smooth on the h.264 videos, but now no video at all, or at least not in any newer ROM I've tried.

Assuming your signature means Energy Cookie Home Tab 21907, I just did a Task 29 and loaded the latest Energy CHT 21914 from August 28th. I opened Total Commander and clicked on a MP4 file that was h.264 and AAC encoded (which launches HTC Player). Videos from MP4forHD and the Video Encoding GUI have no audio (video plays smooth). Videos from AVS, Nero, and Xilisoft have audio, but no video.
So the search continues...

Why don't you try a mediaplayer alternative like TCPMP ?

I do and have. TCPMP cannot keep up with the frame rates of h.264 files unless you severely reduce the bit rate. I've tested frame rates of 23.97 and 29.97 at bit rates of 500k to 2000k and they don't play smoothly in TCPMP, or CorePlayer (which I've purchased). If you take a look at the Video Encoding GUI http://forum.xda-developers.com/showthread.php?t=467112 it will tell you not to use CorePlayer as it does not support hardware acceleration.
The fun thing is I have a bunch of videos that I converted to h.264 so that my 2 1/2 year old son can watch videos upon request. On my Fuze, everything worked fine. He dropped my Fuze, so AT&T replaced it with a Tilt2. I didn't like the ROM, so I upgraded to an Energy ROM (which are great). Unfortunately, I have not found a ROM other than the original AT&T TilT2 ROM to play h.264 videos. Having to re-encode them is a ridiculous solution.

I simply have the mp4 video at my SD card. The HTC Album recognises that and I can play from there. Again, it depends on the file size and bitrate. I have a 640x480 video with a data bitrate of 1 Mbps and it plays well on TP2. I have other that are 1280x720 and bitrate of 9 Mbps and it would be a few sec per frame. But then you really need a laptop to play that kind of video.
Now I think you need to make sure the video is encoded properly. I use Adobe Media Encoder to encode my videos. The 1280x720 video I refer to above, however was straight from my Sanyo Xacti camcorder as it captures H.264 AAC video directly.

Just one more thing you can try. The TP2 camera can captue H.264 video. (You would need to set the format at the advanced video camera settings there.) Then try playback the capture video. If it doesn't play back that video, then there definitely is something wrong with the ROM you have.

How could there be something wrong with just about every ROM I've tried, on two different phones. Also, I've put in a support incident with HTC and they've verified it's an issue. Below is a list of ROMs I've tried.
These ROMs will play h.264 videos made with Video encoding GUI or Mp4ForHD apps here on XDA:
AT&T Stock Tilt2 ROM
Josh's Black 1.8b_Sense_2.5_2012_Norm
These ROMs don't correctly play h.264 videos. When playing video encoded with Video Encoding GUI or Mp4ForHD, there's video, but no sound. When playing videos from AVS, Nero, or Xilisoft, there's audio, but no video:

Hi,
This is something I too am actually searching for...
I have discovered that agent47's Valkyrie Roms do play, with sound and video, the mp4s that I had encoded for my Touch HD. Link is http://forum.xda-developers.com/showthread.php?t=569507
Now why they do, and what makes them different, are some extra drivers present, that I would love to know...
Do try them ou and let me know your experience.
And, for those that suggest always to try TCPMP or Core player, these two great softwares do not, however, take advantage of the machine's hardware, unlike Album or Media Player. By using the two latter ones to play the mp4 files, the experience is much more fluid and with correct fps...

Sorry to say, that after doing Task 29 and loading tp2_firestorm_v7.3.21914-FX that it's actually worse than all the others I've tried. Using the HTC Player, it freezes upon loading the video. Using Media Player, the program loads and as soon as it stops loading, it closes. I'll add it to my list of the non-workings.

Now that is strange...
I have not yet tried the new version 7.3 of the rom, as my previous tryout was with version 7.0.23123-xt, link here http://valkyrie.htc-files.com/downl...restormLEO/v7.0/tp2_firestorm_v7.0.23123XT.7z
With this one, after task 29, I had perfect results, both sound and video, of mp4s encoded with projection's video encoding gui (link http://forum.xda-developers.com/showthread.php?t=467112 )...
I wonder if the new rom version has somehow broken the previous mp4 compatibility... and this would not be pleasant at all.
I will have to try the new version, after I finish with the energy rom (so far also not compatible, sound wise...)
In the meantime, do try the previous version mentioned, and let me know if it works for you.

P

Just one more thing you may want to try. The way your phone is connected to PC (USB to PC setting):
1. ActiveSync
2. Disk Drive
Try the disk drive option. It won't modify the file as it get copied onto the phone.

Okay... I've tried the following Valkyrie ROMS-
tp2_firestorm_v7.0.23123XT
tp2_firestorm_v7.3.21914-FX
tp2_firestorm_v7.3.23134-FX
The 7.0.23123XT version plays h.264 videos that were encoded with MP4ForHD or the Video Encoding GUI just fine. It only plays audio from h.264 videos encoded with AVS, Nero, or Xilisoft.
The two 7.3 versions don't work at all. They crash when trying to load any h.264 video.
At least I've got a few ROMs now that work. I'll try and take a look at the files to see what's different.

I either use the Disk Drive mode to transfer videos, or I pop the MicroSD car into an SD adapter and put it right in my laptop. I don't believe there's a setting issue at play as that wouldn't explain why different ROMs work and don't work.

[Q] HD Video Playback and Framerate

Before I start, let me clarify that this is about playback of stored videos files (avi, mp4, wmv, mov, etc), not recording frame rate or the playback of recorded videos from the phone. Searching yielded hundreds of results, but none of them fit the scope of my question as far as I could tell. If there is something out there, please link and excuse this question.
So, my question and issue is pretty straight forward: whenever I try to play video files I have (IE: downloaded mp4 files), I get really really poor frame rates. Poor meaning 7-13 frames per second.
So the video sucks, and plays in a fairly smooth slow motion. The sound is fine, causing the video to go out of sync, and once the audio timeline ends the video file closes. The built-in player won't even load them, but RockPlayer does. I think I tried xyplayer as well. I figure this is just a codec / software issue, but all lower resolution video files (same format) play fine, so it seems to be unrelated to the applications I'm using. 800x640 video files, no problem; 1280x720 video files, not gonna happen. The videos play fine on a computer, obviously, and my buddy's Windows Phone 7 plays them fine as well (Zune software).
Any ideas?

what bitrate are the videos that skip?

I don't have many on my phone right now, but one of them is 741Kbps, about one third larger than another video that plays perfectly fine, albeit at a lower resolution. Admittedly I know very little about video encoding and all of that.

What rom are you using?

Currently Burnt Droid (1.4), but I've had the same problem on other roms (sense). I recall having this issue on an AOSP rom once, but I can't say that with complete confidence.

Bump; is this really not an issue for people? I can try and grab a sample video if that helps? I figured this would be a more global thing, not just me. The main reason I need (or want) this to work is because all of my online class lectures are recorded in this format and being able to watch the lectures on the go would be extremely beneficial.

Hmm, ok, so it took that sentence for me to realize I'm an idiot. I've tried hardware mode with every video file I have put on my phone (avi, mp4, wmv), but wasn't surprised when they didn't play-- if they did, couldn't I just use the stock video player?-- but my school files for example are .mp4, which should play, but I guess the system player doesn't support whatever encoding/bitrate these videos are made with? Does this mean I won't get this to work unless I re-encode / convert the files I have into a new mp4 the phone will support natively?
Excuse my ignorance on the issue; I guess my understanding of the application and android system is more limited than I initially thought.

Html5 video tag doesn't work in Android with local video files

Hi everyone.
I am not able to reproduce local video files, using video tag of Html5 in an Android application, even developing an Android cross walk application, the video Html5 tag only works fine with videos located in a http server, with local files includes in the application only works in full screen mode, otherwise only the audio is played, the video is showed as a black screen.
I think the issue could be related to the Web browser for Android, I tested the application in the latest version of the chrome Mobile browser and the behaviour is exactly the same.
Anyone know how to solve this issue?
By the way, the Android version where I am trying is 4.1
Thanks a lot in advance.
Regards
David

the issue is not with browser.its with the video. i too had the same issue when playing mp4 videos locally in webview. i tried different versions/ encoders when converting video and it worked without any code changes. just try converting the mp4 to different encoder or better try with a 3gp format. it will work

Thanks si much, I did some tests just related to you mean, but it doesn't work for me, may be if you could me the encoder, format, bitrate, etc. I will able to solve as you did.
Do you remember the combination you used.
Thanks a lot
Regards
David

I was able to execute correctly the app in other device, with mp4 and with webM video format, but in the initial device doesn't work fine, there, the video only works in full screen mode or if the video is located in Internet, if the video is located locally it only is reproduced if I tap the full screen icon of the Html5 video tag controls.
For this reason, I am not sure that the problem is related to the video, but with the Web browser, or may be with the device, the app works fine in other device with Android 4.2 and Android 4.4.
Any idea about how to try to solve for Android 4.1?
Thanks a lot in advance.
Regards
David

The problem is that the local files have "file://" protocol so they can't be played by just using the video tag, you need to use a video cordova plugin like:
https://github.com/moust/cordova-plugin-videoplayer
https://github.com/nchutchind/Streaming-Media-Cordova-Plugin
Hope I helped

Suggestion
I would suggest checking that the local file exists.
Perhaps a popup-box or console log that displays the url, and manually navigate to the URL.
This is almost always the issue for me -- other than file corruption it's self.
