* avformat/aadec: Replace strncpy by av_strlcpyAndreas Rheinhardt2021-03-05
| | | | | | | | | | | While this usage of strncpy is correct, said function nevertheless has the disadvantage of not automatically ensuring that the destination string is zero-terminated. So av_strlcpy should be preferred. This also removes a -Wstringop-truncation warning from GCC (it doesn't matter whether the buffer is truncated, as long as it can fit all the names of the supported codecs).

* aadec: improve seeking in mp3 contentKarsten Otto2018-07-14
| | | | | | | | | | | | 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 embedded id3 tags, it will mispredict the correct offset, and at worst skip an extra frame. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* aadec: add chapters and seekingKarsten Otto2018-07-09
| | | | | | | | | | | | | | | 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 timestamp to position conversion. Then in read_seek, find the chapter containing the seek position, calculate the nearest chunk position, and reinit the read_seek state accordingly.

* aadec: improve eof detectionKarsten Otto2018-07-08
| | | | | | | | | 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. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
