decoder: h264: add support for missing second field. Interlaced H.264 video frames always have two fields to decode and display. However, in some cases, e.g. packet loss, one of the field can be missing. This perturbs the reference picture marking process, whereby the number of references available in DPB no longer matches the expected value. This patch adds initial support for missing field within a decoded frame. The current strategy taken is to find out the nearest field, by POC value, and with the same parity. https://bugzilla.gnome.org/show_bug.cgi?id=745048

decoder: h264: improve DPB bumping process for MVC. While invoking the DPB bumping process in presence of many views, it could be necessary to output previous pictures that are ready, in a whole. i.e. emitting all view components from the very first view order index zero to the very last one in its original access unit; and not starting from the view order index of the picture that caused the DPB bumping process to be invoked. As a reminder, the maximum number of frames in DPB for MultiView High profile with more than 2 views is not necessarily a multiple of the number of views. This fixes decoding of MVCNV-4.264.

h264: simplify reference picture marking process. ... to build the short_ref[] and long_ref[] lists from the DPB, instead of maintaining them separately. This avoids refs/unrefs while making it possible to generate the list based on the actual picture structure. This also ensures that the list of generated ReferenceFrames[] actually matches what reference frames are available in the DPB. i.e. short_ref[] and long_ref[] entries are implied from the DPB, so there is no risk of having "dangling" references.

But since the commits landed, it doesn't drop P-frame and does try to decode it continuously because active_sps is still alive. See ensure_sps function. But there are prev_frames and prev_ref_frames reset already, then it causes assertion.

h264: fix activation order of picture and sequence parameters. Delay ensure_context() until we actually need a VA context for allocating new VA surfaces, and then GstVaapiPictures, but also when a real activation of a new picture parameter set occurs, thus also implying an activation of the related sequence parameter set. The most important thing was to drop the global pps and sps pointers since they may not have matched the currently activated picture parameter or sequence parameter sets at the specified decode point. Anoter positive side-effect is that this cleans up all occurrences of decode_current_picture() to only keep those useful in decode_picture(), before a new picture is allocated, or in decode_sequence_end() when an end-of-stream or end-of-sequence condition occurred.

The relevant part from the H264 spec is: > Decoders that conform to one or more of the profiles specified in Annex A rather than the profiles specified in Annexes G or H shall ignore (remove from the bitstream and discard) the contents of all NAL units with nal_unit_type equal to 14, 15, or 20. To eliminate side effects from the offending units: - PPS's with a broken seq_parameter_set_id (referring to dropped subset SPS's) are ignored. - The NAL parsing is skipped and their flags are set to GST_VAAPI_DECODER_UNIT_FLAG_SKIP. - Prefix units are not stored in prev_pi.

decoder: h264: add support for missing second field. Interlaced H.264 video frames always have two fields to decode and display. However, in some cases, e.g. packet loss, one of the field can be missing. This perturbs the reference picture marking process, whereby the number of references available in DPB no longer matches the expected value. This patch adds initial support for missing field within a decoded frame. The current strategy taken is to find out the nearest field, by POC value, and with the same parity. https://bugzilla.gnome.org/show_bug.cgi?id=745048

decoder: h264: fix activation of picture and sequence parameters. At the time the first VCL NAL unit of a primary coded picture is found, and if that NAL unit was parsed to be an SPS or PPS, then the entries in the parser may have been overriden. This means that, when the picture is to be decoded, slice_hdr->pps could point to an invalid (the next) PPS entry. So, one way to solve this problem is to not use the parser PPS and SPS info but rather maintain our own activation chain in the decoder. https://bugzilla.gnome.org/show_bug.cgi?id=724519 https://bugzilla.gnome.org/show_bug.cgi?id=724518

To eliminate side effects from the offending units: - PPS's with a broken seq_parameter_set_id (referring to dropped subset SPS's) are ignored. - The NAL parsing is skipped and their flags are set to GST_VAAPI_DECODER_UNIT_FLAG_SKIP. - Prefix units are not stored in prev_pi.

libs: humongous code style fix As part of the upstreaming process of gstreamer-vaapi into the GStreamer umbrella, we need to comply with the project's code style. This meant to change a lot of code. It was decided to use a single massive patch to update the code style. I would like to apologize with the original developers of this code because of the history breakage.

libs: decoder: h264: decode SVC base layer only Drops non-base NALs when the base-only property is set to TRUE. This modifies the behavior for MVC streams with base-only too: All the non-base units are dropped before they are decoded instead of dropping the non-base frames. The relevant part from the H264 spec is: > Decoders that conform to one or more of the profiles specified in Annex A rather than the profiles specified in Annexes G or H shall ignore (remove from the bitstream and discard) the contents of all NAL units with nal_unit_type equal to 14, 15, or 20. To eliminate side effects from the offending units: - PPS's with a broken seq_parameter_set_id (referring to dropped subset SPS's) are ignored. - The NAL parsing is skipped and their flags are set to GST_VAAPI_DECODER_UNIT_FLAG_SKIP. - Prefix units are not stored in prev_pi. Otherwise, parse_slice() would use them even if they are flagged to be skipped. Subset SPS's and slice extension units are not stored there either. https://bugzilla.gnome.org/show_bug.cgi?id=732266 Signed-off-by: Sreerenj Balachandran <sreerenj.balachandran@intel.com>
