* 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.

* Use gmtime_r instead of gmtime and localtime_r instead of localtimeMartin Storsjö2014-10-26
| | | | | | | | | | | gmtime isn't thread safe in general. In msvcrt (which lacks gmtime_r), the buffer used by gmtime is thread specific though. One call to localtime is left in avconv_opt.c, where thread safety shouldn't matter (instead of making avconv depend on the libavutil internal header).

* 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>

* wtv: Seek by sector properlyLuca Barbato2013-10-18
| | | | | | | | | Use an helper function to seek by sector to avoid possible mistakes due shifting by WTV_SECTOR_BITS a 32bit integer. Contrary to common intuition, a 32 bit integer left shifted by a 64 bit integer does not promote the 32 bit integer to 64 bit before shifting.

* lavu: replace int/float punning functionsMans Rullgard2011-12-11
| | | | | | | | | | | | | | | | | | The existing functions defined in intfloat_readwrite.[ch] are both slow and incorrect (infinities are not handled). This introduces a new header with fast, inline conversion functions using direct union punning assuming an IEEE-754 system, an assumption already made throughout the code. The one use of Intel/Motorola extended 80-bit format is replaced by simpler code sufficient under the present constraints (positive normal values). The old functions are marked deprecated and retained for compatibility. Signed-off-by: Mans Rullgard <mans@mansr.com>

| | | | | | | | Manual replacements are done in this commit. In many cases, the id is some constant made up number (e.g. 0 for video and 1 for audio), which is then not used in the demuxer for anything. Those ids are removed.

* handle malloc failures in ff_get_wav_headerMax Horn2011-04-14
| | | | | | | | | | | ff_get_wav_header is reading data from a WAVE file and then uses it (without validation) to malloc a buffer. It then proceeded to read data into the buffer, without verifying that the allocation succeeded. To address this, change ff_get_wav_header to return an error if allocation failed, and adapted all calling code to handle that error. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
