transcoding bug with MPEG2 video in M2TS container
Posted: Tue Apr 29, 2014 9:53 am
I'm having problems creating an MPEG2 video in M2TS container.
At roughly 20 seconds, I start to hear audio and video glitches. At 25 seconds, I start to hear audio that I heard at the beginning of the file and video rendering is completely frozen. I'm using VLC 2.1.3 Rincewind for playback. I suppose it's plausible that VLC has the bug, but neither Win8's xbox video nor WindowsMediaPlayer apps seem to render MPEG2-TS container content, so it's difficult for me to blame VLC for the issue.
I am using MediaCoder Premium x64 Version 0.8.29 build 5608, Edition: vod
Here's a description of my preset.
[Video tab] VideoBitrate:20000 RateMode:CBR Format:MPEG2 Encoder:FFmpeg/Auto Source:MEncoder/Auto
[Audio tab] Format: AC-3 Bitrate:320kbps Encoder:FFmpeg/Auto Source:Default/Auto Resample:Original BitDepth:16
[Container] Container:M2TS Multiplexer:TSMuxer
[Picture] Resize:1920x1080 FrameRate:60.000 ColorSpace:I420 AspectRatio:KeepDisplayAR Crop:Disable Effects:SourceFilter
The input video file is freely available. It's the 2D/4K/60fps version of Big Buck Bunny, available here: http://bbb3d.renderfarming.net/download.html
Starting with the broken preset, I tried some derivative presets that seem to work.
-Format=H.264 Encoder=x264/Auto Source=MEncoder/Auto, Multiplexer:TSMuxer
-Format=H.264 Encoder=x264/Auto Source=MEncoder/Auto, Multiplexer:FFmpeg
-Container:MPEG-TS, Multiplixer:FFmpeg
-Container:MPEG-TS, Multiplixer:TSMuxer
Starting with the broken preset, I also tried this derivative preset that immediately results in a MediaCoder error: 009
-Container:M2TS, Multiplixer:FFmpeg
I tried to upload the preset, but the website said .txt and .xml files were not permitted. Here is the preset in the message.
