[FFmpeg-devel] Error Decoding Stream (AAC)

[Marcus Frasier]

Here is a quick output of what I'm running. This is the second pass:

The first pass runs fine, and that command is:

ffmpeg -y -i southernman.mp4 -threads 2 -pass 1 -an -vcodec libx264 -b 
600000 -r 30 -s 480x368 -bf 3 -qcomp 0.7 -g 300 -keyint_min 30 -refs 5 
-loop 1 -flags +4m v -cmp 256 -coder 0 -me_range 16 -sc_threshold 40 
-i_qfactor 0.71 -level 30 -qmi n 10 -qmax 51 -qdiff 4 -subq 1 -me_method 
hex -partitions 0 -trellis 0 mixed_refs southernmanredone.mp4

So I assume it's because I'm telling it to use libfaac in the second 
pass. Other videos convert just fine, but as this is for a video 
uploading community, I want to make sure I test with a broad range of files.
