avcodec/mp3: fix skipping zeros Commits 43bc5cf9 and c5371f77 add code for skipping initial zeros in mp3 packets. This code forgot to report to the user that data was skipped at all. Since audio codecs allow partial packet decoding, the user application has to rely on the return value. It will remove the data reported as consumed by the decoder, and feed it to the decoder again. This resulted in the mp3 frame after the zero region to be decoded over and over again, until the zero region was finally skipped by the application. Fix this by including the amount of skipped bytes to the number of consumed bytes returned by the decode call. Fixes trac ticket #4890. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=cb1da9fb8d71bb611a7b0028914c97afc3f5711d --- libavcodec/mpegaudiodec_template.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/libavcodec/mpegaudiodec_template.c b/libavcodec/mpegaudiodec_template.c index b7b9dbd..0f32ac7 100644 --- a/libavcodec/mpegaudiodec_template.c +++ b/libavcodec/mpegaudiodec_template.c @@ -1657,9 +1657,11 @@ static int decode_frame(AVCodecContext * avctx, void *data, int *got_frame_ptr, uint32_t header; int ret; + int skipped = 0; while(buf_size && !*buf){ buf++; buf_size--; + skipped++; } if (buf_size < HEADER_SIZE) @@ -1714,7 +1716,7 @@ static int decode_frame(AVCodecContext * avctx, void *data, int *got_frame_ptr, return ret; } s->frame_size = 0; - return buf_size; + return buf_size + skipped; } static void mp_flush(MPADecodeContext *ctx) _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog
