[FFmpeg-devel] [RFC] fftools/ffmpeg and libavdevice/sdl issue

I have not read that. If that is true, maybe he could start with
refraining from using expressions like “horrible hacks”.

> Of course it's also objectionable for SDL to be modelled as a muxer,

Sigh. Do we have to explain this once again? Devices have to present as
muxers and demuxers in order to be usable transparently by applications
designed for plain files. And anyway, the manner frames enter or leave a
device is orthogonal to the implementation of said device, so bringing
this question in the discussion is irrelevant.

No. Or [citation needed].

It is less than standards-compliant and portable, but it is doable.

This is something that should be fixed, do you not think?

I called them “threading infrastructure”, you called them “main-loops”.
Can we stop nitpicking on words and make an honest attempt at
understanding what the other is saying or is it too much to ask?
