* avcodec/opus: always use ambisonic layout for mapping family 2James Almer2022-03-20
| | | | | | | | | | | No need to use a Custom layout when the non diegetic channels can be described as a standard mask. This fixes: 45684/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_LIBOPUS_fuzzer-5039410989629440 Signed-off-by: James Almer <jamrial@gmail.com>

* lavc/bsf: add general documentationAnton Khirnov2022-03-19
| | | | Also, place the BSF api docs in their own doxygen group.
* avcodec/flashsv2enc: Avoid opening and closing z_streamAndreas Rheinhardt2022-03-19
| | | | | | Instead initialize a z_stream during init and reset it when needed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/lclenc: Use ff_deflate_init/end() wrappersAndreas Rheinhardt2022-03-19
| | | | | | | | | They return nicer error messages on error; furthermore, they also use our allocation functions. It also stops calling deflateEnd() on a z_stream that might not have been successfully initialized. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/pngenc: Use ff_deflate_init/end() wrappersAndreas Rheinhardt2022-03-19

* avcodec/zmbvenc: Use ff_deflate_init/end() wrappersAndreas Rheinhardt2022-03-19
| | | | | | | They emit better error messages (it does not claim that inflateInit failed upon an error from deflateInit!) and uses our allocation functions. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/zlib_wrapper: Add wrapper for deflateInit()Andreas Rheinhardt2022-03-19
| | | | | | | | | | | The rationale is the same as for the wrappers for inflateInit(), although the case for it is admittedly not so strong because there are less users of deflateInit(). Also remove an unnecessary inclusion of config.h in libavformat/protocols.c in order to trigger a request for reconfigure (which is needed for CONFIG_DEFLATE_WRAPPER to take effect).

* avcodec/pngenc: Don't use deflateInit2() with default parametersAndreas Rheinhardt2022-03-19
| | | | | | Use deflateInit() instead. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/pngdec: Don't open and close z_streams unnecessarilyAndreas Rheinhardt2022-03-19
| | | | | | | | Instead reuse and reset a single z_stream. Also use FFZStream in decode_zbuf(), because it has nicer error messages. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/flashsv: Use ff_inflate_init/end()Andreas Rheinhardt2022-03-19
| | | | | | | This fixes the problem of potentially closing a z_stream that has never been successfully initialized. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/lcldec: Use ff_inflate_init/end(), cleanup genericallyAndreas Rheinhardt2022-03-19
| | | | | | | | | Returns better error messages in case of error and deduplicates the inflateInit() code and also allows to cleanup generically in case of errors as it is save to call ff_inflate_end() if ff_inflate_init() has not been called successfully. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/zlib_wrapper: Add wrappers for zlib inflateInit, inflateEndAndreas Rheinhardt2022-03-19
| | | | | | | | | | | | | | | | | It is not documented to be safe to call inflateEnd() on a z_stream that has never been successfully been initialized by inflateInit(), but just zeroed. It just happens to work and several codecs rely on this (they have FF_CODEC_CAP_INIT_CLEANUP set and even call inflateEnd() when inflateInit() failed or has never been called). To avoid this, other codecs recorded whether their zstream has been initialized successfully or not. This commit adds wrappers for inflateInit() and inflateEnd() that do what these other codecs do; furthermore, they also take care of properly setting up the zstream before inflateInit() and emit an error message in case of error.

* avcodec/pngenc: Avoid potentially truncating integersAndreas Rheinhardt2022-03-19
| | | | | | | | | So use 64bits for max_packet_size instead of size_t which might be 32 bits; this is consistent with ff_alloc_packet(). Also remove a redundant size check (ff_alloc_packet() already checks for that). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* Keep including the full version.h when headers are included externallyMartin Storsjö2022-03-19
| | | | | | | | | This avoids unnecessary churn and build breakage for users, by making sure the whole version.h is included like it has been so far, while keeping the benefit of not needing to rebuild most files in the ffmpeg tree on minor/micro bumps.

* libavcodec: Split version.hMartin Storsjö2022-03-16
| | | | | | | | | | | | | | This avoids including version.h in all source files, avoiding unnecessary rebuilds when the version number is bumped. Only version_major.h is included by the main header, which defines availability of e.g. FF_API_* macros, and which is bumped much less often. This isn't done for libavutil/version.h, because that header needs to be included essentially everywhere due to LIBAVUTIL_VERSION_INT being used wherever an AVClass is constructed.
