[FFmpeg-devel] [PATCH v4 0/3] libavformat/aadec: seek support

A patch series adding seek support to libavformat/aadec. This fourth version of the series addresses some more comments from the mailing list: Patch 2/3 now uses avpriv_set_pts_info(). Otherwise, it is still based on skipping through the content to collect chapter boundaries. This is not optimal,

[FFmpeg-devel] [PATCH v4 1/3] aadec: improve eof detection

Remember the end position of audio content in the file and check it during read_packet. There always seems to be other data beyond it, which could be misinterpreted as more audio. Also add some extra avio_read error checks, to bail early in case of a broken/truncated file. --- libavformat/aadec.c

[FFmpeg-devel] [PATCH v4 3/3] aadec: improve seeking in mp3 content

MP3 frames may not be aligned to aa chunk boundaries. When seeking, calculate the expected frame offset in the target chunk. Adjust the timestamp and truncate the next packet accordingly. This solution works for the majority of tested audio material. For some rare encodings with mp3 padding or emb

[FFmpeg-devel] [PATCH v4 2/3] aadec: add chapters and seeking

read_packet reads content in chunks. Thus seek must be clamped to valid chunk positions in the file, which in turn are relative to chapter start positions. So in read_header, scan for chapter headers once by skipping through the content. Set stream time_base based on bitrate in bytes/s, for easy t

[FFmpeg-devel] [PATCH] libavcodec/mpegaudiodecheader.c : prevent reserved id misinterpretation

Check the MPEG version ID for the reserved bit pattern 01, and abort header parsing in that case. This reduces the chance of misinterpreting arbitrary data as a valid frame start, and prevents the resulting audio artifacts. --- libavcodec/mpegaudiodecheader.c | 5 +++-- 1 file changed, 3 insertion
