      codecs: h264decoder: let print_ref_pic_list_b print the correct list name. · f9d7b708
      He Junyan authored
      The print_ref_pic_list_b now not only needs to trace the ref_pic_list_b0/1,
      but also need to trace the ref_frame_list_0_short_term. We need to pass the
      name directly to it rather than an index to refer to ref_pic_list_b0/1.

      kmssink: Fix fallback path for driver not able to scale scenario · d2a7b763
      Devarsh Thakkar authored
      When driver return error on update plane request, kmssink
      disables the scaling and retries plane update.
      While doing so kmssink was matching the source rectangle dimensions
      to the target rectangle dimensions which were calculated
      as per scaling but this is incorrect, instead what we want here is
      that target rectangle dimensions should match the source rectangle
      dimensions as scaling is disabled now and so we match result
      rectangle dimensions with source rectangle dimensions.
      While at it, also match the result rectangle coordinates for
      horizontal and vertical offsets with source rectange coordinates,
      as since there is no scaling being done so no recentering is

      videoparsers: vp9: Need to process the first frame even not key. · e9d0d19f
      He Junyan authored
      Some cut VP9 streams begin with a non key frame. The current code
      just bail out the parse_process_frame() if not a key frame. Because
      of this, we do not set the valid caps before we push the data of the
      first frame(even this first frame will be discarded by the downstream
      decoder because it is not a key frame).
      The pipeline such as:
      gst-launch-1.0 filesrc location=some.ivf ! ivfparse ! vp9parse !
        vavp9dec ! fakesink
      will get a negotiation error and the pipeline can not continue. The
      correct behaviour should be: the decoder discard the first frame and
      continue to decode later frames successfully.
      So, when the parse does not have valid stream info(should be the first
      frame case), we should continue and report caps.

      Some programs specify a PCR PID but don't actually store any PCR values, or are
      way too far apart.
      In order to gracefully handle those situations, we will queue up to a certain
      amount of pending buffers before deciding to give up on that PCR PID and not use
      any (i.e. using DTS/PTS values as-is)

      He Junyan authored
      In low_latency mode, try to bump the picture as soon as possible
      without the frames disorder:
      1. We can directly output the continuous non-reference frame.
      2. Consider max_num_reorder_frames, which is special useful for
         I-P mode.
      3. Consider the leading pictures with negative POC.
      4  Output small POC pictures when non-reference frame comes.
      4. Output the POC increment<=2 pictures. This is not 100% safe,
         but in practice this condition can be used.

      codecs: h264dec: Modify the DPB need bump check. · f1df1207
      He Junyan authored
      Accord to spec, we should not add the current picture into the DPB
      when we check whether it needs to bump, so the checks of the IDR and
      the "memory_management_control_operation equal to 5" are no needed.
      And the spec also says that the DPB only needs to bump when there is
      no empty frame buffer left(We handle the IDR cases in other places).
      We need to follow that and the max_num_reorder_frames is useless.
      We also minus 1 in has_empty_frame_buffer because the current frame
      has not been added yet.

      * If we have an index table for non-framed essence, we can handle it
      * The demuxer has a state which indicates whether it will next fetch a KLV or
      data contained *within* a KLV.
      * The position on Essence Tracks always correspond to the next entry to fetch,
      demuxer offset will be skipped accordingly whenever we switch between
      partitions (in case of resyncs). A copy of the main clip/custom KLV for that
      partition is kept to track the position within the essence of that partition.
      * For clip/custom-wrapped raw audio, if the edit rate is too small (and would
      cause plenty of tiny buffers to be outputted), specify a minimum number of edit
      units per buffer.

      mxfdemux: Refactor index table and offset handling · ac483b23
      Edward Hervey authored
      * Streamline offset <=> entry handling. Historically the demuxer didn't support
      information from index tables and stored the discovered information in an array
      per track. When index table support was added, a parallel system was setup for
      that relationship. This commit unifies this into one system with the
      `find_edit_entry()` and `find_entry_for_offset()` functions.
      * By extension, per-track offset entry tables are only created/used if no index
      table is present for those tracks.
      * Use index table information as-is. The index table system from MXF is quite
      complex and there are various ways to use the information contained
      within. Instead of converting that information we store the data from the tables
      as-is and extract the needed information when needed.
      * Handle index tables without entries (i.e. all content package units are of the
      same size).
      * Allow collecting index table segments as we go instead of only once if a
      random-index-pack is present. This also improves support of some files in
      * When searching for keyframe entries, use the keyframe_offset if
      present (speeds up searching).
      * For interleaved content (i.e. several tracks in the sample essence container),
      we use a system to be able to identify the position of each track in the delta
      entries of index tables.
      * Handle temporal offset only on tracks which *do* need it (as specified in the
      delta entries of the index tables). If present, those offsets are stored in a
      pre-processed table which allows computing PTS from DTS with a simple offset.
      * Add a quirk for files which are known to be have wrongly stored temporal
      * Overall opens the way to handle more types of MXF files, especially those with

      mxfdemux: Handle temporal reordering shift · dfee771a
      Edward Hervey authored
      This is similar to how the same issue was handled in qtdemux.
      In order for the "DTS <= PTS" constraint to be respected, we calculate the
      maximum temporal reordering that can happen (via index tables).
      If there is a non-0 temporal reordering, we:
      * Shift all outgoing PTS by that amount
      * Shift segment for that stream by that amount
      * Don't modify DTS (i.e. they might end up having negative running-time, before
      the start of the segment)
      Also ensure all entries have a valid PTS set, previously this wouldn't be set
      for entries with a temporal offset of 0.
      Fixes gstreamer/gst-plugins-bad#584

      dash: Store entire ContentProtection node in protection event data · bc09d8cc
      Philippe Normand authored
      Some manifests use the ContentProtection node to store additional information
      such as the license server url. Our MPD parser used to process the
      ContentProtection node, extracting Playready PSSH boxes. However for other DRM
      systems, only the `value` attribute was passed down to the protection event, so
      for example, Widevine data was not parsed at all and "Widevine" was passed to
      the event, which is not very useful for decryptors that require a PSSH init
      Parsing should now be done by decryptors which will receive the entire
      ContentProtection XML node as a string. This gives more "freedom" to the
      decryptor which can then detect and parse custom nodes as well.

      The VP9 streams have the ability to change the resolution dynamically

      So we need to check the resolution change for each frame and do the

      Some insaned stream may play in resolution A first and then dynamically
      changes to B, and after 1 or 2 frames, it use a show_existing_frame to
      repeat the old frame of resolution A before. So, not only new_picture(),
