Hi,
There is no point of having these output devices as all the
functionality is contained in the 'ffplay' tool. If people wanted to
integrate these devices in their own programs instead of using the
ffmpeg tool then they are far too constrained for proper control, not to
mention output devices have been quick hacky in libavdevice for a long
time. There are three patches attached to deprecate the SDL2, OpenGL,
and libcaca devices.
