Tsutomu Seki	9b445663a5	avfilter/opencl: Fix program_opencl for source code larger than 64kB The condition (pos < len) is always true and the rest of the OpenCL program code would not be read, while the maximum number of "rb" is "len - pos - 1", and then, the maximum number of the "pos" is "len - 1".

Niklas Haas	3cc3f5de2a	avcodec/hevcdec: apply H.274 film grain Similar in spirit and design to `66845cffc3`, but slightly simpler due to the lack of interlaced frames in HEVC. See that commit for more details. For the seed value, since no specification for this appears to exist, I semi-arbitrarily decided to base it off the POC id alone, since there's no analog of the idr_pic_id in HEVC's I-frames. This design is stable across remuxes and seeks, but changes for adjacent frames with a period that's typically long enough not to be noticeable, which makes it satisfy all of the requirements that a film grain seed should have. Tested with and without threading, using a patch to insert film grain metadata artificially (for lack of real files containing film grain).	3 years ago

Andreas Rheinhardt	f626a3d0e0	Revert "avfilter/vf_idet: reduce noisyness if the filter has been auto inserted" This reverts commit `723c37d3b7`. Said commit was in preparation for auto-inserting the idet filter. This has never happened; even if it did, the code is wrong, because it segfaults if the filter instance doesn't have a name (having one is not mandatory). Furthermore, it is documented for libavfilter to not assign any semantics to the name, which this check violates. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago

Mark Reid	716b396740	avfilter/vf_lut3d: add x86-optimized tetrahedral interpolation I spotted an interesting pattern that I didn't see before that leads to the implementation being faster. The bit shifting table I was using before is no longer needed, and was able to remove quite a few lines.

Marton Balint	9420f7e095	avformat/mpegts: fix max_packet_size in mpegts payload parsing The maximum allowed useful PES payload data was set to PES_packet_length, but it is in fact smaller by the length of the PES header. This changes how corrupt streams are packetized: - If PES header length is bigger than PES_packet_length then the PES packet payload will be handled as an unbound packet - PES packets with payload across multiple MPEGTS packets will always be splitted if with the next chunk of data the payload should exceed PES_packet_length, previously a PES_header_length amount of excess was allowed.

Marton Balint	aeea2ad0e4	avformat/mpegts: rename PES total_size to PES_packet_length This renames PESContext->total_size to PESContext->PES_packet_length and keeps it 0 for unbound packets, so its name and semantics will match the standard.
