* lavc/h264_ps: always include the stop bit in [s|p]ps->datarcombs2022-06-01
| | | | | | | | The VideoToolbox hwaccel needs the entire NAL (including the stop bit), but ff_h2645_packet_split may remove it. Detect this case by looking for bit counts divisible by 8 and insert a stop-bit-only 0x80 byte. Signed-off-by: rcombs <rcombs@rcombs.me>

* libavcodec/qsvenc: expose only supported optionsDmitry Rogozhkin2022-05-25
| | | | | | | | | | | | | | vp9, hevc, avc, mpeg2 QSV encoders inherit common list of options (QSV_COMMON_OPTS) while bunch of options is not actually supported by current qsv code. The only codec which supportes everything is avc, followed by hevc, while vp9 and mpeg2 significantly fall behind. This creates difficulties for the users to use qsv encoders. This patch fixes options list for encoders leaving only those which are actually supported.

* avcodec/mpegvideoenc: Remove ineffective optionsAndreas Rheinhardt2022-05-24
| | | | | | | | | | | | | | | | This commit removes the ineffective FF_MPV_DEPRECATED_ options, namely mpeg_quant (this is only an option for MPEG-4), a53cc (this is only an option for MPEG-2), force_duplicated_matrix (applies only to MJPEG) and b_strategy, b_sensitivity and brd_scale (these options only make sense for encoders supporting B-frames, which currently means the MPEG-1/2 and MPEG-4 encoders). Given that these options never changed the outcome of encoding, they are removed at once. Notice that the options for the encoders for which it made sense are not affected by this.

* avcodec/pthread_frame: Don't update the first thread ctx before freeingAndreas Rheinhardt2022-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, ff_frame_thread_free() uses the last worker thread to updates the first worker thread via update_context_from_thread() immediately before freeing all these worker threads. This is a remnant of the time in which the first worker was special. (E.g. the first worker shared its AVCodecInternal with the public AVCodecContext.) But these times are over (none of the uses of is_copy matter for ff_frame_thread_free()); nowadays the only thing that update_context_from_thread() does is referencing a few buffers/frames and replacing them with other references instead. These new references will then be freed immediately thereafter when the first worker thread is freed. Ensuring that the code is free of double-frees is achieved by using reference-counted structures (or in case of AVChannelLayouts: by giving each worker its own copy). Some archaeology: a) Updating the first worker thread from the last one used has been done since frame-threading was added in 37b00b47cbeecd66bb34c5c7c534d016d6e8da24. b) The precursor to ff_mpv_common_end() checked for is_copy before freeing pictures (i.e. it only freed them for the first worker thread). c) Commits c2dfb1e37cc72bf144545c4410a4621cbff5c4b1 and e33811bd2686411233cb0eb4a4ee45eb99d7e736 modified the update_thread_context function of the H.264 decoder so that it could fail before calling ff_mpeg_update_thread_context(). d) This led to a double free/an assert violation with a H.264 sample for which ff_mpeg_update_thread_context() is not reached for the final update_context_from_thread(). Commit a6e4796fbf0aa9b13451a8ef917ecc4e80d1d272 added code to fix this sample. e) This issue was fixed (even with the last mentioned commit reverted) when the H.264 decoder was deMpegEncContextized in commit b7fe35c9e50e1701274364adf7280bf4a02b092b (merging commit 2c541554076cc8a72e7145d4da30389ca763f32f). f) mpegvideo.c stopped using is_copy when it was switched to refcounted frames in 759001c534287a96dc96d1e274665feb7059145d. g) 1f4cf92cfbd3accbae582ac63126ed5570ddfd37 removed the init_thread_copy callbacks; now no FFCodec.close callback checks for is_copy at all any more.

* avcodec/internal: Hide stuff only used by the core decode APIAndreas Rheinhardt2022-05-12
| | | | | | | | | | | | | | | | | | | | | | The general decoding API uses bitstream filters and an AVFifo and therefore AVCodecInternal contains pointers to an AVBSFContext and to an AVFifo and lavc/internal.h includes lavc/bsf.h and lavu/fifo.h. Yet actually, only two files are supposed to use these, namely avcodec.c and (mainly) decode.c. For all the other files, it should be an opaque type that they should not touch and that they need not know anything about. This can be achieved by not including these headers and using the structs instead of the corresponding typedefs. This also forces translation units that really use the BSF and the FIFO APIs themselves to include the relevant headers directly instead of relying on indirect inclusions (up until now, even avcodec.c and decode.c relied on fifo.h to be included by internal.h). Of course, it also avoids unnecessary rebuilds when bsf.h or fifo.h change. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
