• fate/jpeg2000dec : add support for p0_10.j2k

  16 juin 2024, par Pierre-Anthony Lemieux

  fate/jpeg2000dec : add support for p0_10.j2k
  p0_10.j2k is one of the reference codestreams included in Rec. ITU-T T.803 | ISO/IEC 15444-4.
  
  Adding this test was made possible by commit 6f4a95cfb8e6ed97fdd1027251181caded44860f.

• lavu/pixdesc : handle xv30be in av_[read|write]_image_line

  4 décembre 2022, par Philip Langdale

  lavu/pixdesc : handle xv30be in av_read_image_line
  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.

• avformat/avformat : Avoid including codec.h, frame.h

  2 septembre 2023, par Andreas Rheinhardt

  avformat/avformat : Avoid including codec.h, frame.h
  AVCodec is only ever used as an incomplete type (i.e. via a pointer
  
  to an AVCodec) in avformat.h and it is not really part of the core
  
  of avformat.h or libavformat ; almost none of our internal users
  
  make use of it (and none make use of hwcontext.h, which is implicitly
  
  included). So switch to use struct AVCodec, but continue to include
  
  codec.h for external users for compatibility.
  Also, do the same for AVFrame and frame.h, which is implicitly included
  
  by codec.h (via lavu/hwcontext.h).
  Also, remove an unnecessary inclusion of <time.h>.
