Some encoders (e.g., libx264) dump encoder configuration as user
data unregistered SEI message. This option try to print it as
ascii character when possible.

The loop iterates over the length of the vector, not the order. This is
to avoid reloading the same data for each lag value. However this means
the loop only works if the maximum order is no larger than VLENB.
The loop is roughly equivalent to:
for (size_t j = 0; j < lag; j++)
autoc[j

Why?

FFmpeg doesn't support tv-range RGB throughout most of its pipeline, so
we should keep the warning. However, in case something does support it
we should at least keep it tagged properly. Additionally, the encoder
writes this tag if the space is tagged as such so this makes a round
trip work as it s

And OpenGL, since it depends on SDL for its stand-alone setup.

Now it's time to talk about the libavdevice/sdl issue.
SDL output is broken with ffmpeg multithread refactor. SDL 'muxer' write_header
and write_packet must be run in the same thread. And to make it work portable
and reliable, SDL 'muxer' must be run in main thread. It's a common requirement

The correct way to te
Added the change to the documentation and added error checking on `strtol`,
according to the stdlib documentation.
The documentation for `strtol` says that on error, 0 is returned. This makes it
impossible to specify a window handle of 0 (the whole desktop), but that case
is already covered by
