* mpegaudiodec_template: add ability to check CRCLynne2020-05-26
| | | | | | A lot of files have CRC included. The CRC only covers 34 bytes at most from the frame but it should still be enough for some amount of error detection.

* | avcodec/mp3: fix skipping zeroswm42015-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * mp3: enable packed main_data decoding in MP4nu7742015-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 14496-3 suggests packing main_data of MP3 that is usually scattered into multiple frames due to bit reservoir. However, after packing main_data into a access unit, bitrate index in the MPEG audio frame header doesn't match with actual frame size. In order to accept this, this patch removes unnecessary frame size checking on mp3 decoder. Also, mov demuxer was changed to use MP3 parser only on special cases (QT MOV with specific sample description) to avoid re-packetizing. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
