aacsbr: Turnoff in the event of over read. Aliased compressed AAC bytes are almost certainly not meaningful SBR data. In the wild this causes harsh artifacts switching HE-AAC streams that don't have SBR headers aligned with segment boundaries. Turning off SBR falls back to a default set of upsampling parameters that can function as a sort of error concealment. This is consistent with how the decoder handles other sorts of errors. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=2c8a3aa985acc906ecab37357f2798da7cb9822d --- libavcodec/aacsbr_template.c | 1 + 1 file changed, 1 insertion(+) diff --git a/libavcodec/aacsbr_template.c b/libavcodec/aacsbr_template.c index cf8621e..750131c 100644 --- a/libavcodec/aacsbr_template.c +++ b/libavcodec/aacsbr_template.c @@ -1137,6 +1137,7 @@ int AAC_RENAME(ff_decode_sbr_extension)(AACContext *ac, SpectralBandReplication if (bytes_read > cnt) { av_log(ac->avctx, AV_LOG_ERROR, "Expected to read %d SBR bytes actually read %d.\n", cnt, bytes_read); + sbr_turnoff(sbr); } return cnt; } _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog
