This commit actually enables subtitle filtering in ffmpeg by
sending and receiving subtitle frames to and from a filtergraph.
The heartbeat functionality from the previous sub2video implementation
is retained and applied to all subtitle frames (bitmap, text, ..).
The other part of sub2video funct
- overlaytextsubs {VS -> V)
Overlay text subtitles onto a video stream.
- textsubs2video {S -> V)
Converts text subtitles to video frames

Root commit for adding subtitle filtering capabilities.
In detail:
- Add type (AVMediaType) field to AVFrame
Replaces previous way of distinction which was based on checking
width and height to determine whether a frame is audio or video
- Add subtitle fields to AVFrame
- Add new struct AVSubt
v14 Update:
- FEATURE-COMPLETE
Fixes:
- get_subtitle_buffer: set extended data
- overlaygraphicsubs: copy time base from input
- subtitle_heartbeat: Fix pts when re-sending
- subtitle_heartbeat: only beat on video stream timing
- subtitle_heartbeat: propagate beat over all input files
- overlay t

You're right, this could break on systems with 32-bit int.

Use the external libjxl library to add decoding for JPEG XL
images, and add the appropriate image2 muxers and demuxers
to read/write JPEG XL image files.

This fixes linking errors where variables cannot be correctly linked in
from an external shared library such as with msvc (requires dllimport which
is not used by libaom). Instead just call the function that returns the

The IMF demuxer accepts as input an IMF CPL. The assets referenced by the

If -asset
bit_rate is not a critical field, and we shouln't hard fail if we
can't caluclate it due to a large timebase - it needlessly breaks
valid files.
