 Note:
-------

The linux versions need the libs from gtk-3.10, gtk-4.6
  or higher versions of them, and if not statically linked,
  the libs from FFmpeg-7.0
The i386 are 32-bit, and x86_64 are 64-bit versions
The 'cutterff-1.3-linux-*-static-gtk?.tar.bz2' versions
  have the libraries of FFmpeg-7.0 and the encoders
  'libx264' and 'libx265' statically linked. The supported
  hardware accelerators are 'vaapi' and 'vdpau', and the
  shared libraries 'libva', 'libva-drm' and 'libvdpau' must
  be installed.
The win32 version has the libs from gtk-2.24 statically
  linked, and the FFmpeg-7.0 libaries and the encoders
  'libx264' and 'libx265' as 'dll' included. The supported
  hardware accelerators are 'd3d11va2' and 'dxva2'.
  Tested with Windows-7 (32-bit) and Windows-11 (64-bit)

 ChangeLog
-----------

version 1.3 (Jul 13 2024)
-----------

* gui.c
    + in 'cff_gui_file_selection_new_gettext' the
      filechooser gets a combo-box for selecting a
      hwaccel. A tooltip shows available decoders
    + in 'cff_gui_file_save' a tooltip shows the
      available (but disabled) encoders

* ffmpeg.c
    + works with FFmpeg version 7.0
    + memory leak in 'cff_ffmpeg_program_open',
      'vframe.tmppkt' only unrefed, not freed. Now
      this is okay, see below
    + in 'cff_ffmpeg_file_open' the temporary packet
      and frames were allocated once, avoids allocating
      and freeing them in other functions
    + added 'vframe.has_keyframe', which is set in
      'cff_ffmpeg_get_frame_dts'. If no keyframe was
      found, I-Frames was treated as keyframes.
    + if in 'cff_ffmpeg_get_frame_dts' a frame with
      no (unknown) picture type will return an error
    + in function 'cff_ffmpeg_get_frame' entering
      'drain_mode' and storing the packet data (dts+pos)
      in 'video->vframe.pktlist' have been changed.
      Also rewind and searching again if the first
      packet after seeking has not at least a distance
      of seven frames to the next frame was removed
    + function 'cff_ffmpeg_copy_softcut_position_index'
      was removed in CutterFF-1.1, now it's back
    + decoding 'vp9' with multi-threading wasn't working.
      Setting the frame-type to 'slice' works.
    + encoding 'mpeg2' fails due invalid timebase. Fixed!
    + flushing the encoder in 'cff_ffmpeg_copy_softcut'
      was removed
    + removed 'kCFFStreamFlagBsfInit', copying the
      parameters from bsf to codec already done in
      'cff_ffmpeg_copy_open'
    + in 'cff_ffmpeg_get_bitstream_filter_names' the
      filter is only shown if the stream has a codec
      for it
    + saving a cut list adds 'LastFrame', this is the
      dts of the last video frame. Needed if loading
      with a different decoder to calculate the offset
    + the function 'cff_ffmpeg_get_encoder_names' returns
      a negative value if encoding should be disabled

* gprop.c
    + added item 'kPropStrFileHWAccel'
