Hi,

I have a mezzanine file in which I have 8 different audio streams, and I'm trying to mix the audio into stereo mix aac and map it into the second stream of an mp4 in a video, but for some reason ffmpeg keeps placing the audio in the first stream and the video in the second. Any help on mapping would be great. Thanks!

Output:

/ffmpeg -i '/media/local-trans02/GV-16/compress/extract-sound/ayahuasca-vine-of-the-soul-feature-1080p2997.mov' -map 0:v:0 -vcodec libx264 -b:v 1500k -filter_complex amerge=inputs=3 -ac 2 -acodec libvo_aacenc -b:a 128k -t 30 '/media/local-trans02/BLANK01-STG/gravitas-12-16/compressed-files-gravitas/needs-sound/ahay-test.mp4'
