ffmpeg: video file played OK on Ubuntu, but no sound on XP
- by Andy Le
I created a video clip using ffmpeg (vcodec: mpeg2video, acodec: AC3 5.1).
The file can be played normally on Ubuntu, but when I play it on an XP machine, there is no sound. I can play AC3 files and other movies with AC3 sound. I already tried many codec packs and many players.
When I compare the MediaInfo tab of the Properties window of the file with another playable movie, I see that the Audio Identifier of the audio stream in my file is 0x80 while it is 0x02 in the other movie.
So I guess that's why players on XP can't recognize the audio codec. When I use an MKV container instead of MPEG (still mpeg2video codec), then the result is OK on both Ubuntu and XP (with the correct Audio ID). I really need MPEG though.
Any idea?
This is the command I used:
~/ffmpeg/ffmpeg/ffmpeg -loop_input \
-t 97 -r 30000/1001 -i v%4d.tga -i final.ac3 \
-vcodec mpeg2video -qscale 1 -s 400x400 -r 30000/1001 \
-acodec copy -y out6.mpeg 2
This is the output of mediainfo (on Ubuntu):
