Re: [FFmpeg-user] Query

You'll have to do this in two steps. here is the audio step. Replace the *.wav files here with the actual path and filenames. (also, if the wav files are 24 bit you'll have to add -acodec pcm_s24le in front of the file names) ffmpeg -i front_left.wav -i front_right.wav -i front_center.wav -i lfe.

Re: [FFmpeg-user] Query

should those six separate audio tracks become a 5.1 audio file, or should they be pasted one after the other in a line? if the latter you're talking about concatanation; if the former, you'ree talking about merging the files. I'm not even going to get into the problems with your video question. __
