* avcodec/hevcdec: Add VDPAU to list of supported formatsManojGuptaBonda2020-07-09
| | | | | | | | | | | | | | Added VDPAU to list of supported formats for HEVC10 and 12 bit formats also added 42010 bit to surface_parameters and new VDP chroma formats to VDPAUPixFmtMaps Add HEVC 420 10/12 Bit and 444 10/12 Bit support for VDPAU YUV444P10 is defined as the 444 surface with 10bit valid data in LSBs but H/w returns Data in MSBs Hence if we map output as YUV444p16 it is filtering out the LSB to convert to p10 format.

* pthread_frame: change the criterium for updating thread contextsAnton Khirnov2020-07-07
| | | | | | | | | | | Currently the next thread's context is updated from the previous one's if the codec descriptor is not marked as intra-only. That is not entirely correct, since that property does not necessarily imply anything about how a specific decoder implementation behaves. Instead, use the presence of the update_thread_context() callback to decide whether an update should be performed. Fixes races in CFHD, should cause no behaviour change in any other decoders.

* avfilter/vf_edgedetect: properly implement double_threshold()Valery Kot2020-07-06
| | | | | | | | | | | | | | Important part of this algorithm is the double threshold step: pixels above "high" threshold being kept, pixels below "low" threshold dropped, pixels in between (weak edges) are kept if they are neighboring "high" pixels. The weak edge check uses a neighboring context and should not be applied on the plane's border. The condition was incorrect and has been fixed in the commit.

* avcodec/h26[45]_metadata_bsf: Use separate contexts for reading/writingAndreas Rheinhardt2020-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, both bsfs used the same CodedBitstreamContext for reading and writing; as a consequence, the state of the writer's context at the beginning of writing a fragment is exactly the state of the reader after having read the fragment; in particular, the writer might not have encountered one of its active parameter sets yet. This is not nice and may lead to invalid output even when the input is completely spec-compliant: Think of an access unit containing a primary coded picture referencing a PPS with id id (that is known from an earlier access unit/from extradata), then a new version of the PPS with id id and then a redundant coded picture that is also referencing the PPS with id id. This is spec-compliant, as the standard allows to overwrite a PPS with a different PPS in between coded pictures and not only at the beginning of an access unit. In this scenario, the reader would read the primary coded picture with the old PPS and the redundant coded picture with the new PPS (as it should); yet the writer would write both with the new PPS as extradata which might lead to errors or to invalid data being output without any error (e.g. if the two PPS differed in redundant_pic_cnt_present_flag). The above scenario does not directly translate to HEVC as long as one restricts oneself to input with nuh_layer_id == 0 only (as cbs_h265 does: it currently strips away any NAL unit with nuh_layer_id > 0 when decomposing); if one doesn't the same issue as above can happen. If one also allowed input packets to contain more than one access unit, issues like the above can happen even without redundant coded pictures/multiple layers. Therefore this commit uses separate contexts for reader and writer. Reviewed-by: Mark Thompson <sw@jkqxz.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
