* avformat/mxfenc: Never set codec_ul UID to NULLAndreas Rheinhardt2021-02-16
| | | | | | | | | | | | | | | | | mxf distinguishes codec profiles by different UIDs and therefore needs to check that the input is actually compatible with mxf (i.e. if there is a defined UID for it). If not, then sometimes the UID would be set to NULL and writing the (video) packet would fail. Yet the following audio packet would trigger writing the header (which has been postponed because the UID is not known at the start) and if the UID is NULL, this can lead to segfaults. This commit therefore stops setting the UID to NULL if the input is incompatible with mxf (it has initially been set to a generic value in mxf_write_header()). Fixes #7993.

* avcodec/frame_thread_encoder: Avoid allocations of AVFramesAndreas Rheinhardt2021-02-16
| | | | | | | | | | | | | | | | Up until now, when using frame threaded encoding, an AVFrame would be allocated for every frame to be encoded. These AVFrames would reach the worker threads via a FIFO of tasks, a structure which contained the AVFrame as well as an index into an array which gives the place where the worker thread shall put the returned packet; in addition to that, said structure also contained several unused fields. This commit changes this: The AVFrames are now allocated during init in the array that is up until now only used to return the packets. The contents to be encoded are put into the AVFrame in the same array element that is also used to return the packets. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avcodec/frame_thread_encoder: Avoid allocations of AVPackets, fix deadlockAndreas Rheinhardt2021-02-16
| | | | | | | | | | | | | | | | | | | | | Up until now, when doing frame thread encoding, each worker thread tried to allocate an AVPacket for every AVFrame to be encoded; said packets would then be handed back to the main thread, where the content of said packet is copied into the packet actually destined for output; the temporary AVPacket is then freed. Besides being wasteful this also has another problem: There is a risk of deadlock, namely if no AVPacket can be allocated at all. The user doesn't get an error at all in this case and the worker threads will simply try to allocate a packet again and again. If the user has supplied enough frames, the user's thread will block until a task has been completed, which just doesn't happen if no packet can ever be allocated. This patch instead modifies the code to allocate the packets during init; they are then reused again and again. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/frame_thread_encoder: Fix segfault on allocation errorAndreas Rheinhardt2021-02-16
| | | | | | | | | | | Fixes a segfault from av_fifo_size(NULL) that happens in ff_frame_thread_encoder_free if the fifo couldn't be allocted; furthermore the mutexes and conditions that are destroyed in ff_frame_thread_encoder_free are not even initialized at this point, so don't call said function.

* 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).
