Is there some GPU resource limit that affects how many parallel
processes can be in use? Is it possible to check it and more
importantly, inform user in case we reach that limit 'you ran out of gpu,
please call your local dealer' ?
This might come just from me not being that familiar with internals of
gpu encoding stuff, but I don't really know how they internally allocate
things between multiple processes trying to do gpu encoding. So is it
depending on amount of parallel encodes, or profiles/resolutions tried
to encode in parallel or some other factor?
There is an innocence in admiration; it is found in those to whom it
has not yet occurred that they, too, might be admired some day.
