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

Hi,
It fails fate source guard header tests,
The headers should be changed from AVFILTER_DNN_BACKEND_xxx to

BTW I think we should have an ffmpeg controlled repo hosting the
