The FFmpeg internal V4L2RequestDescriptor type is not meant to be used by applications, instead applications should treat the returned frames as if a AVDRMFrameDescriptor was returned, as defined by the DRM_PRIME pix fmt. Remove the custom implementation of GetRequestBuffer and use the base GetDRMBuffer function instead. Signed-off-by: Jonas Karlman <jonas@kwiboo.se>
av_hwdevice_ctx_init() is already called internally by FFmpeg function av_hwdevice_ctx_create(), and is not meant to be called a second time. Remove the unneeded av_hwdevice_ctx_init() to simplify the code. Signed-off-by: Jonas Karlman <jonas@kwiboo.se>
