[SOLVED] Specify which streams to convert in ffmpeg

penyuan · 09-20-2013, 06:42 AM

Hello,

I am converting (using ffmpeg version 2.0-0988709) a file from m4v to webm using my usual routine. But this time I got the following error:

Quote:

Stream mapping:
Stream #0:0 -> #0:0 (h264 -> libvpx)
Stream #0:1 -> #0:1 (aac -> libvorbis)
Stream #0:2 -> #0:2 (? -> ?)
Encoder (codec none) not found for output stream #0:2

I don't care about Stream #0:2, how do I tell ffmpeg to only convert streams #0:0 and #0:1??? Thanks!

You could try passing the map option to ffmpeg.

-map 0:0 -map 0:1

This tells ffmpeg to process only streams 0:0 and 0:1

If 0:2 is a subtitle stream, you can pass the -sn option to ignore the stream.

If the above fails, try different programs like Handbrake and VLC to convert the videos.

Seemed to work, thank you!!
