* hwcontext_vulkan: wait and signal semaphores when transferring to CUDALynne2020-12-05
| | | | | Same as when downloading. Not sure why this isn't done, probably because the CUDA code predates the sync mechanism we settled on.

* avcodec/av1dec: Fix leak in case of failureAndreas Rheinhardt2020-12-05
| | | | | | | | | | | | | A reference to an AV1RawFrameHeader and consequently the AV1RawFrameHeader itself and everything it has a reference to leak if the hardware has no AV1 decoding capabilities or if some other error happens. It happens e.g. in the cbs-av1-av1-1-b8-02-allintra FATE-test; it has just been masked because the return value of ffmpeg (which indicates failure when using Valgrind or ASAN) is ignored when doing tests of type md5.

* avcodec/utils: Remove ff_codec_open2_recursive()Andreas Rheinhardt2020-12-04
| | | | | | | | | | | | | | | This function existed to enable codecs with non-threadsafe init functions to initialize other codecs despite the fact that normally no two codecs with non-threadsafe init functions can be initialized at the same time (there is a mutex guarding this). Yet there are no users of this function any more as all users have been made thread-safe (switching away from ff_codec_open2_recursive() was required for this as said function requires the caller to hold the lock to the mutex guarding the initializations and this is only true for codecs with the FF_CODEC_CAP_INIT_THREADSAFE flag unset); so remove it.

* avcodec: Fix invalid uses of ff_codec_open2_recursive()Andreas Rheinhardt2020-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally no two codecs with FF_CODEC_CAP_INIT_THREADSAFE unset can be initialized at the same time: a mutex in avcodec_open2() ensures this. This implies that one cannot simply open a codec with a non-threadsafe init-function from the init function of a codec whose own init function is not threadsafe either as the child codec couldn't acquire the lock. ff_codec_open2_recursive() exists to get around this limitation: If the init function of the child codec to be initialized is not thread-safe, the mutex is unlocked, the child is initialized and the mutex is locked again. This of course has as a prerequisite that the parent AVCodecContext actually holds the lock, i.e. that the parent codec's init function is not thread-safe. If it is, then one can (and has to) just use avcodec_open2() directly (if the child's init function is not thread-safe, then avcodec_open2() will have to acquire the mutex itself (and potentially wait for it), so that it is perfectly fine for an otherwise thread-safe init function to open a codec with a potentially non-thread-safe init function via avcodec_open2()). Yet several of the users of ff_codec_open2_recursive() have the FF_CODEC_CAP_INIT_THREADSAFE flag set; this only worked because all the child codecs' init functions were thread-safe themselves so that ff_codec_open2_recursive() didn't touch the mutex at all. But of course the real solution to this is to directly use avcodec_open2(). Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
