* doc/protocols: Remove third party serverDerek Buitenhuis2022-12-12
| | | | | | | | | | | | We do not endorse or recommend specific third party servers or companies that users' data will be funneled through. It is also incorrectly describing how FFmpeg currently works. Should have been part of 412922cc6fa790897ef6bb2be5d6f9a5f030754d but was missed.

* avcodec/mjpegdec: Only use receive_frame for SMVJPEGAndreas Rheinhardt2022-12-10
| | | | | | | | | | | | | | | | | Only one codec using mjpegdec.c actually creates multiple frames from a single packet, namely SMVJPEG. The other can use the ordinary decode callback just fine. This e.g. has the advantage of confining the special SP5X/AMV code to sp5xdec.c. This reverts most of commit e9a2a8777317d91af658f774c68442ac4aa726ec; of course it is not a simple revert: Way too much has changed; furthermore, outright reverting the sp5xdec.c changes would readd a stack packet to sp5x_decode_frame() which is not desired. In order to avoid this without modifying the given AVPacket, a variant of ff_mjpeg_decode_frame() with explicit buf and size parameters has been added.

* avcodec/mjpegdec: Restrict AVID MJPEG to non-SMVJPEGAndreas Rheinhardt2022-12-10
| | | | | | | | | | | | AVID content is not supposed to be SMVJPEG; given that both these codecs involve manipulating image dimensions and cropping dimensions, it makes sense to restrict the AVID codepaths to non-SMVJPEG codecs in order not to have to think about what if SMVJPEG happens to have a codec tag indicating AVID.

* lavu/pixdesc: handle xv30be in av_[read|write]_image_linePhilip Langdale2022-12-08
| | | | | | | | | | | | | | | | | | | | xv30be is an obnoxious format that I shouldn't have included in the first place. xv30 packs 3 10bit channels into 32bits and while our byte-oriented logic can handle Little Endian correctly, it cannot handle Big Endian. To avoid that, I marked xv30be as a bitstream format, but while that didn't produce FATE errors, it turns out that the existing read/write code silently produces incorrect results, which can be revealed via ubsan. In all likelyhood, the correct fix here is to remove the format. As this format is only used by Intel vaapi, it's only going to show up in LE form, so we could just drop the BE version. But I don't want to deal with creating a hole in the pixfmt list and all the weirdness that comes from that. Instead, I decided to write the correct read/write code for it. And that code isn't too bad, as long as it's specialised for this format, as the channels are all bit-aligned inside a 32bit word.

* lavu/hwcontext_vaapi: Skip 'vgem' driverBrian Norris2022-12-08
| | | | | | | | | | | | | | | | | | | There can be more than one available render node, and it's not guaranteed the first node we come across is the correct one. In particular, 'vgem' devices are common, and are never VAAPI-enabled and thus not valid here. We have a 'kernel_driver' arg already for specifying a single driver we *do* want, but it doesn't support a negation, nor a list. It's easier just to automatically skip 'vgem' anyway, to avoid foisting this burden on users. This has precedent in libva-utils already: bfb6b98ed62a exclude vgem node and invalid drm node in vainfo https://github.com/intel/libva-utils/commit/bfb6b98ed62ac14a840ba62639ab902a23912258 Signed-off-by: Brian Norris <briannorris@chromium.org>

* libavfilter/qsvvpp: Change the alignment to meet the requirement of YUV420P ↵Wenbin Chen2022-12-08
| | | | | | | | | | | | | | | | | | | | format When process yuv420 frames, FFmpeg uses same alignment on Y/U/V planes. VPL and MSDK use Y plane's pitch / 2 as U/V planes's pitch, which makes U/V planes 16-bytes aligned. We need to set a separate alignment to meet runtime's behaviour. Now alignment is changed to 16 so that the linesizes of U/V planes meet the requirment of VPL/MSDK. Add get_buffer.video callback to qsv filters to change the default get_buffer behaviour. Now the commandline works fine: ffmpeg -f rawvideo -pix_fmt yuv420p -s:v 3082x1884 \ -i ./3082x1884.yuv -vf 'vpp_qsv=w=2466:h=1508' -f rawvideo \ -pix_fmt yuv420p 2466_1508.yuv Signed-off-by: Wenbin Chen <wenbin.chen@intel.com>

* Revert "avcodec/decode: use a packet list to store packet properties"James Almer2022-12-07
| | | | | | | | | | | | | | The idea behind last_pkt_props was to store the properties of the last packet fed to the decoder. Any sort of queueing required by CODEC_CAP_DELAY decoders that consume several packets before they start outputting frames should be done by the decoders in question. An example of this is libdav1d. This is required for the following commits that will fix last_pkt_props in frame threading scenarios, as well as maintain its contents during flush.
