[FFmpeg-devel] [PATCH][RFC] avcodec: add AV_HWACCEL_CODEC_CAP_EXPERIMENTAL flag

[James Almer]

This flag replaces the deprecated, non-prefixed HWACCEL_CODEC_CAP_EXPERIMENTAL
one.

No HWAccel uses HWACCEL_CODEC_CAP_EXPERIMENTAL at all. I wonder if we
shouldn't instead just not bother replacing it and consider adding it
once and if an hwaccel is ever committed in an unfinished way.
