[issue2551] DTS reencode to AAC 2ch/AC3 6ch
New submission from mt m...@nef.wh.uni-dortmund.de: When I try to reencode some DTS audio track first to AAC 2 channel and AC3 6 channel, I get an error Resampling with input channels greater than 2 unsupported. Can not resample 6 channels @ 48000 Hz to 2 channels @ 48000 Hz. First AC3 6 channel and then AAC 2 channel works. AFAIK some devices like AppleTV require the AAC track first. ffmpeg -i input.mkv -y -map 0:0 -vcodec copy -map 0:1 -acodec aac -ab 128k -ac 2 -strict experimental output.m4v -map 0:1 -acodec ac3 -ab 448k -ac 6 -newaudio produces the error. ffmpeg -i input.mkv -y -map 0:0 -vcodec copy -map 0:1 -acodec ac3 -ab 448k -ac 6 output.m2v -map 0:1 -acodec aac -ab 128k -ac 2 -strict experimental -newaudio works. -- messages: 13452 priority: normal status: new substatus: new title: DTS reencode to AAC 2ch/AC3 6ch type: bug FFmpeg issue tracker iss...@roundup.ffmpeg.org https://roundup.ffmpeg.org/issue2551

Carl Eugen Hoyos ceho...@rainbow.studorg.tuwien.ac.at added the comment: You can either wait until issue 185 is fixed or just use an additional call to ffmpeg to encode audio prior to encoding video and muxing.

[issue2547] H.264 decoder x86 asm bug
Ronald S. Bultje rsbul...@gmail.com added the comment: I was wrong, it was the 16x16, there was an overflow in one of the functions. Attached patch fixes it. I've rearranged the calls a little so that it hopefully doesn't get slower. I haven't benchmarked the change, but effect should be minimal (if any).
