      WIP: h265parse: Don't push NALs before we have HEADERS · cd11a069
      Nicolas Dufresne authored 
      Otherwise we may endup pushing incomplete caps.

This patch isn't ready yet, as it will merge PPS/SPS/VPS in the same
GstBuffer. This is valid as per current definition of alignment=nal,
but is also a behaviour change. It's also weird, since it only merge
these for the first set.

      h26xparse: Handle the case we already parsed the frame · ffa80239
      Nicolas Dufresne authored 
      As we no longer accumulate 2 NALs before producing any data, we may
endup with the case where we have completly parsed the frame data and
then get called on handle_frame(). This was triggering the assertion
current_off < size, as the current offset was equal to the size.
Handle this just like we'd do in other case, like broken NAL etc.

      h265parse: Differentiate PREFIX SEI from SUFFIX · 13837f3a
      Nicolas Dufresne authored 
      There is some code to fixup broken stream that uses the SEI location,
this code is meant to locate SUFFIX SEI only. This should prevent
unwanted side effect if SUFFIX SEI is used.

      h265parse: Add AUD insertion · f2aed343
      Nicolas Dufresne authored 
      This add a feature that existed in h264parse already, which is the
insertion of AUD NAL whenever these are missing. This simplify the
detection of frame start and also allow producing valid MPEG TS files.

      h265parse: Don't add latency when not needed · a25ba128
      Nicolas Dufresne authored 
      We no longer add latency when doing AU->AU, AU->NAL and NAL->NAL
parsing.

      h265parse: Don't wait for next NAL if input is aligned · 40ad4931
      Nicolas Dufresne authored 
      Waiting for the next NAL increases the latency. If alignment=nal/au
has been negotiated, assumes the the buffer contains a complete
NAL and don't except a second start-code. This way, nal -> nal,
au -> au and au -> nal no longer introduce latency.

As a side effect, the collect_pad() function was not able to poke at the
following NAL. This call is now moved before processing the NAL, so
it's looking at the current NAL before it's ingested into the parser
state in order to dermin if the end of an AU has been reached. The AUD
injection state as been adapted to support this.

      h265parse: Set PTS/DTS and DISCONT on crafted NAL · d3f15f2e
      Nicolas Dufresne authored 
      When we inject a NAL in the bitstream before another one, make
sure to pass both DTS and PTS. Also make sure to transfer the
DISCONT flag properly.
