* avformat/utils: Fix undefined NULL + 0Andreas Rheinhardt2021-02-14
| | | | | | | | | | | This is undefined behaviour in C, so use data = len ? data + len : data instead of data += len. GCC optimizes the branch away in this case; Clang unfortunately doesn't.

* avdevice/avdevice: Deprecate AVDevice Capabilities APIAndreas Rheinhardt2021-02-14
| | | | | | | | | | | | | | It has been added in 6db42a2b6b22e6f1928fafcf3faa67ed78201004, yet since then none of the necessary create/free_device_capabilities functions has been implemented, making this API completely useless. Because of this one can already simplify avdevice_capabilities_free/create and can already remove the function pointers at the next major bump; given that the documentation explicitly states that av_device_capabilities is not to be used by a user, it's options can already be removed (save for the sentinel).

* avcodec/hevcdec: check that the local context list was allocated before ↵James Almer2021-02-11
| | | | | | | | | | | | | | | | | | | dereferencing it Since the decoder is not flagged as init cleanup capable, hevc_decode_free() is being called manually if the hevc_decode_extradata() call fails at the end of hevc_decode_init(). In a frame threading scenario, however, if AVCodec->init() returns an error, ff_frame_thread_free() will be called regardless of the above flag being set or not, resulting in hevc_decode_free() being called a second time for the same context. Workaround this by ensuring pointers are not dereferenced if they are NULL, and set the decoder as init cleanup capable while at it. Fixes ticket #9099. Signed-off-by: James Almer <jamrial@gmail.com>

* avutil/common: Move everything inside inclusion guardsAndreas Rheinhardt2021-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libavutil/common.h is a public header that provides generic math functions whereas libavutil/intmath.h is a private header that contains plattform-specific optimized versions of said math functions. common.h includes intmath.h (when building the FFmpeg libraries) so that the optimized versions are used for them. This interdependency sometimes causes trouble: intmath.h once contained an inlined ff_sqrt function that relied upon av_log2_16bit. In case there was no optimized logarithm available on this plattform, intmath.h needed to include common.h to get the generic implementation and this has been done after the optimized versions (if any) have been provided so that common.h used the optimized versions; it also needed to be done before ff_sqrt. Yet when intmath.h was included from common.h and if an ordinary inclusion guard was used by common.h, the #include "common.h" in intmath.h was a no-op and therefore av_log2_16bit was still unknown at the end of intmath.h (and also in ff_sqrt) if no optimized version was available. Before a955b5965825631986ba854d007d4e934e466c7d this was solved by duplicating the #ifndef av_log2_16bit check after the inclusion of common.h in intmath.h; said commit instead moved these checks to the end of common.h, outside the inclusion guards and made common.h include itself to get these unguarded defines. This is still the current state of affairs. Yet this is unnecessary since 9734b8ba56d05e970c353dfd5baafa43fdb08024 as said commit removed ff_sqrt as well as the #include "common.h" from intmath.h. Therefore this commit moves everything inside the inclusion guards and makes common.h not include itself. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
