Author: Kostya Shishkov <[email protected]> Committer: Kostya Shishkov <[email protected]> Date: Thu Mar 29 12:08:07 2012 +0200 mp3dec: perform I/S and M/S only when frame mode is joint stereo. Looks like some LAME versions produce dual stereo mode MP3s with flags for intensity and middle stereo set. In this mode those flags should be ignored like the reference decoder and derived ones do. --- libavcodec/mpegaudiodec.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/libavcodec/mpegaudiodec.c b/libavcodec/mpegaudiodec.c index 6ed124b..0ab87e1 100644 --- a/libavcodec/mpegaudiodec.c +++ b/libavcodec/mpegaudiodec.c @@ -1533,7 +1533,7 @@ static int mp_decode_layer3(MPADecodeContext *s) huffman_decode(s, g, exponents, bits_pos + g->part2_3_length); } /* ch */ - if (s->nb_channels == 2) + if (s->mode == MPA_JSTEREO) compute_stereo(s, &s->granules[0][gr], &s->granules[1][gr]); for (ch = 0; ch < s->nb_channels; ch++) { _______________________________________________ libav-commits mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-commits
