Can you use ffmpeg to encode Vorbis audio?
It can be very time consuming to re-encode the correct stream. FFmpeg can help with this situation: This command copies the video stream from input.webm into output.mkv and encodes the Vorbis audio stream into a FLAC.
When does FFmpeg start writing to the output?
When transcoding audio and/or video streams, ffmpeg will not begin writing into the output until it has one packet for each such stream. While waiting for that to happen, packets for other streams are buffered. This option sets the size of this buffer, in packets, for the matching output stream.

ffmpeg -i input.mp3 output.ogg. This command takes an MP3 file called input.mp3 and converts it into an OGG file called output.ogg. From FFmpeg’s point of view, this means converting the MP3 audio stream into a Vorbis audio stream and wrapping this stream into an OGG container.
How does FFmpeg select stream in out1.mkv?
out1.mkv is a Matroska container file and accepts video, audio and subtitle streams, so ffmpeg will try to select one of each type. For video, it will select stream 0 from B.mp4, which has the highest resolution among all the input video streams. For audio, it will select stream 3 from B.mp4, since it has the greatest number of channels.
