Summary of the bug:
I am stitching 2 videos side by side together into 1 output video (using
libavfilter, the -vf flag). Each source video is mpeg2, the output is
.mp4 (libx264).
I have tried many ways to get the audio to map from an input to the
output, including adding: -c:a libfaac -ac 2 -map 0:v -map 0:a:0 -map
0:a:1
and
-acodec libfaac -ac2 -map 0:1 -map 0:2
I always get the error: "[aresample @ 0x7fdd626023e0] [SWR @
0x7fdd638c2e00] Input channel layout isnt supported"
When I go back to a macports build of ffmpeg (0.7.8) the following command
string: ffmpeg -i /Users/danielpcoffey/Desktop/nate.mov -b 500k -t
00:01:00 -acodec libfaac -ab 64k -vcodec libx264 -r 29.97 -pass 1 -s
1280x720 -vf "movie=/Users/danielpcoffey/Desktop/tommy.mov, setpts=PTS-
STARTPTS [tommyhandle]; [in] pad=1280*2:720 [natehandle]; [tommyhandle]
scale=1280:720 [tommyhandle]; [natehandle][tommyhandle] overlay=1280:0
[out]" ~/Desktop/sidebyside720r500k.mp4
FFMPEG 0.7.8 does function as I expect (joins 2 videos and uses the audio
from the first input). When I do the same exact command string in ffmpeg
0.11.1, I get the error: "[aresample @ 0x7fdd626023e0] [SWR @
0x7fdd638c2e00] Input channel layout isnt supported"
Am I doing something wrong? I'd like to stitch 2 videos together side by
side and use the audio from the first (or alternatively the second or a
mix of both). Please let me know if I can do anything else! Thank you!!
