Current default is 256kbps, which produces inconsistent
results (too high for low-res, too low for hi-res).
Use CRF instead, which will adapt.

SDL_WINDOWEVENT_SIZE_CHANGED should be used instead of SDL_WINDOWEVENT_RESIZED

Purely out of curiosity, what other codes does this affect?

Per matroska spec, v_quicktime contains the complete stsd atom, after
the mandatory size + fourcc. By properly parsing the hvcc sub-atoms of
the track, it becomes possible to demux/decode mp4/mov tracks stored as is
in matroska containers.
Also dvh1 in stsd in matroska is more likely hevc codec
Hi All,
when remuxing some of the mp4 files into the mkv container, not all
video codecs can be properly represented. As such, to make the codec
configuration complete, mkvtoolnix muxes in the full stsd box.
I also switched "detecting" DVH1 in a v_quicktime track in an mkv file, as a
HEVC
LGTM.
Should push soon.
BTW I just noticed that the tensorflow backend is failling to load SR
filter models.
$ python tools/python/convert.py sr_models/srcnn.pb
$ ./ffmpeg -i input.jpg -vf
sr=model=srcnn.model:dnn_backend=tensorflow out_srcnn_tf.png
The above command fails.
It seems commit
