* lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.

* lavf: Check the return value of strftimeMartin Storsjö2014-10-26
| | | | | | | | If the buffer provided to strftime is too small, the buffer contents are indeterminate - it does not guarantee actually null terminating the buffer. Signed-off-by: Martin Storsjö <martin@martin.st>

* mxf: Support AACLuca Barbato2014-08-17
| | | | | | | Update mxf_set_audio_pts to use the container-provided information. The UL is marked as "to be changed in the future", but the current samples in the wild do use it.

* mxf: Lowercase UL stringsLuca Barbato2014-03-19
| | | | The specification uses lower case most of the time.
* mxf: Override faulty PreviousPartition entriesLuca Barbato2014-03-19
| | | | | | | | | | Some files set the PreviousPartition field to point to its own offset. If we are parsing forward the Previous partition is immediately known and its value could be used, otherwise we can safely point to the header. Reported-By: Jean Baptiste Kempf <jb@videolan.org>

* mxfdec: Validate parameters to strftimeMartin Storsjö2014-03-10
| | | | | | | | | | | | The MSVCRT version of strftime calls the invalid parameter handler if the struct values in struct tm are invalid. In case no invalid parameter handler is set for the process, the process is aborted. This fixes fate failures on MSVC builds since 570af382. Based on a patch by Hendrik Leppkes.
