◆ DecoderNeedsReset()

bool MythVDPAUContext::DecoderNeedsReset ( AVCodecContext *  Context)
overridevirtual

Report whether the decoder is known to be errored.

This is used to determine whether the VDPAU display has been preempted. FFmpeg does not deal with preemption so we need to detect it ourselves in the interop class. We do not necessarily have a frame at this point, so need to access the interop through AVHWFramesContext.

Note
May be called without a current AVCodecContext to confirm any previous reset request.
