[issue2651] fftruehd mixes up channels on 7.1 file.
New submission from shadowofdarkness shadowofdarkn...@gmail.com: I got a hold of a 7.1ch TrueHD channel check file from www.demo-world.eu and when I play it using the fftruehd decoder some channels are messed up whereas if I do a pass through it works right which means it is in the decoder. When decoding on my laptop the back left gets swapped with surround back left and back right gets swapped with surround back right When I do a hdmi passthrough by making a .spdif file with ffmpeg and playing it with aplay all channels are correct. The file I used is available at http://www.demo-world.eu/trailers/high-definition-trailers.php and is named Dolby TrueHD Channel Check (Lossless) -- messages: 13836 priority: normal status: new substatus: new title: fftruehd mixes up channels on 7.1 file. type: bug FFmpeg issue tracker iss...@roundup.ffmpeg.org https://roundup.ffmpeg.org/issue2651

So, the buffer that should contain the quantized spectrum coefficients is zero.
Where is it allocated? I can only find:
aacenc.c: 601:
for (j = 0; j chans; j++) {
s-cur_channel = start_ch + j;
s-scoefs = cpe-ch[j].ret;
encode_individual_channel(avctx, s, cpe-ch[j],
cpe-common_window);
}
But this won't be reached before the search_for_quantizers runs.
This is a (completely breaking!) regression introduced by commit 2790d7. It
should probably be reverted.
