* avcodec/pthread_slice: Don't reinitialise initialised mutexAndreas Rheinhardt2022-07-01
| | | | | | | | | | | | | | It results in undefined behaviour. Instead initialize the mutexes and condition variables once during init (and check these initializations). Also combine the corresponding mutex and condition variable into one structure so that one can allocate their array jointly.

* avcodec/libx265: make X265 CSP selection pixel format independentJan Ekström2022-06-27
| | | | | | | | Currently the format listing misses the J formats completely, yet they are marked as supported in the encoder. Thus to make the logic support them while not explicitly listing them, make the logic utilize chroma subsampling information in both width and height available through the pixel format descriptor.

* avcodec: fix time reporting for DFPWM streamsJack Bruienne2022-06-26
| | | | | | | | | | This adds the exact bits per sample for DFPWM to av_get_exact_bits_per_sample. Previously, the DTS and PTS were set to 0 because the codec never reported them, but adding this allows libavformat to automatically set DTS and PTS from the byte position of the stream.

* avcodec/x86/h264_qpel: Remove unused functionsAndreas Rheinhardt2022-06-26
| | | | | | | | | | Forgotten in 4011a76494a5ff6844312813bc753aae8e54c2f0. The reason for this is that these functtions are marked as av_always_inline and GCC does not emit warnings if such functions are unused, so this went unnoticed. Yet Clang does, so this commit removes them. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| | | | | | | | | | | Whether an ICC profile is present or not, the libjxl encoder wrapper should now properly read colorspace tags and forward them to libjxl appropriately, rather than just assume sRGB as before.

Add AV1 VDPAU to list of hwaccels and supported formats Added file vdpau_av1.c and Modified configure to add VDPAU AV1 support. Mapped AV1 profiles to VDPAU AV1 profiles.

* avcodec/hevc_sei: Fix check for SEI endAndreas Rheinhardt2022-06-24
| | | | | | | | | | | | | | The intention behind the current check seems to be to check for the rbsp_trailing_bits() syntax structure which is always 0x80 for valid SEI messages. Yet this is wrong: These trailing bits are not part of the GetBitContext -- they have already been stripped in ff_h2645_packet_split(). And it is harmful, as 0x80 is a legal SEI message payload type (namely for Structure of pictures information SEI messages). We ignore this type of SEI, but because of this bug we also ignored every SEI message in the same NALU following it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/h2645_parse: Only trim RBSP trailing padding if it existsAndreas Rheinhardt2022-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It does not exist for NALUs for which the SODB is empty; it also does not exist for NALUs for which not even the complete header is present. The former category contains end of sequence and end of bitstream units. The latter category consists of one-byte HEVC units (the ordinary H.264 header is only one byte long). This commit therefore stops stripping RBSP trailing padding from the former type of unit and discards the latter type of unit altogether. This also fixes an assertion failure: Before this commit, a one-byte HEVC NALU from an ISOBMFF packet could pass all the checks in hevc_parse_nal_header() (because the first byte of the size field of the next unit is mistaken as containing the temporal_id); yet because the trailing padding bits were stripped, its actually had a size of less than eight bits; because h2645_parse.c uses the checked bitstream reader, the get_bits_count() of the GetBitContext is not 16 in this case; it is not even a multiple of eight and this can trigger an assert in ff_hevc_decode_nal_sei().
