* avcodec/avcodec, avpacket: Return blank packet on av_packet_ref() failureAndreas Rheinhardt2020-03-28
| | | | | | | | | | | | Up until now, it was completely unspecified what the content of the destination packet dst was on error. Depending upon where the error happened calling av_packet_unref() on dst might be dangerous. This commit changes this by making sure that dst is blank on error, so unreferencing it again is safe (and still pointless). This behaviour is documented.

* avcodec/avpacket: Always treat dst in av_packet_ref as uninitializedAndreas Rheinhardt2020-03-28
| | | | | | | | | | | | | | | | | | av_packet_ref() mostly treated the destination packet dst as uninitialized, i.e. the destination fields were simply overwritten. But if the source packet was not reference-counted, dst->buf was treated as if it pointed to an already allocated buffer (if != NULL) to be reallocated to the desired size. The documentation did not explicitly state whether the dst will be treated as uninitialized, but it stated that if the source packet is not refcounted, a new buffer in dst will be allocated. This and the fact that the side-data as well as the codepath taken in case src is refcounted always treated the packet as uninitialized means that dst should always be treated as uninitialized for the sake of consistency. And this behaviour has been explicitly documented. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* lavc/pthread_frame: Update user context in ff_frame_thread_freeLinjie Fu2020-03-27
| | | | | | | | | | | | | | | | | | | | | | Resolution/format changes lead to re-initialization of hardware accelerations(vaapi/dxva2/..) with new hwaccel_priv_data in the worker-thread. But hwaccel_priv_data in user context won't be updated until the resolution changing frame is output. A termination with "-vframes" just after the reinit will lead to: 1. memory leak in worker-thread. 2. double free in user-thread. Update user context in ff_frame_thread_free with the last thread submit_packet() was called on. To reproduce: ffmpeg -hwaccel vaapi(dxva2) -v verbose -i fate-suite/h264/reinit-large_420_8-to-small_420_8.h264 -pix_fmt nv12 -f rawvideo -vsync passthrough -vframes 47 -y out.yuv Signed-off-by: Linjie Fu <linjie.fu@intel.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>

* avcodec/bsf: Beautify log messages from bitstream filtersAndreas Rheinhardt2020-03-21
| | | | | | | | | | | | | | | | Up until now, the name of every AVBSFContext for logging purposes was "AVBSFContext", so that the default logging callback produced output like "[AVBSFContext @ 0x55813bae92c0] Extradata". This has been changed to "[trace_headers @ 0x60a000000700] Extradata" by adding an item_name- function to the AVClass for bitstream filters. Furthermore, the correct category has been set so that the introductory part before the actual message (everything before "Extradata" in the above examples) are displayed in a different colour than the rest.
