Enforce the restart of VideoToolbox when a data / codec error happens.
Usually, it was triggering a fallback (typically on avcodec) every time
an error happened within the played stream, which can happen when
corrupting the input stream.
It was done to protect the decoder against non-playable files for which
the decoder would announce the support but would not be able to decode a
single frame ever. VideoToolbox seems to behave correctly on those files
now so we can make it a default.
The encoder is able to process CVPixelBuffer (chroma CVP*) as input.
Note that this encoder will asynchronously signal its codec extradata at
the first i-frame encoded.
It currently disable B-frame generation since VideotoolBox requires
reordering to happen in the output too, moving the enabling to another
merge request.
