vtdec: expose kVTDecodeFrame_1xRealTimePlayback
Submitted by Ilya Konstantinov
Link to original bug (#752882)
Description
In an RTC pipeline, it might be beneficial to set the kVTDecodeFrame_1xRealTimePlayback flag on the decoded frames.
From the VT headers:
"kVTDecodeFrame_1xRealTimePlayback -- A hint to the video decoder that it would be OK to use a low-power mode that can not decode faster than 1x realtime."
If this cannot be inferred from the incoming GstVideoCodecFrame (I don't suppose elements with is-live=1 leave any hints on the GstBuffers they produce), this could be at the very least be configurable through a property.
