[John Donoghue]

Follow-up Comment #6, bug #56985 (project octave):

Something like:

With the above change in fedora, I then get to:


AVHandler.cc: In member function ‘int AVHandler::setup_read()’:
AVHandler.cc:246:29: error: ‘CODEC_CAP_TRUNCATED’ was not declared in this
scope; did you mean ‘AV_CODEC_CAP_TRUNCATED’?
  246 |   if (codec->capabilities & CODEC_CAP_TRUNCATED)
      |                             ^~~~~~~~~~~~~~~~~~~
      |                             AV_CODEC_CAP_TRUNCATED


Which is mentioned on bug #53801
