Description Ilya Konstantinov 2015-07-26 12:21:33 UTC
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.

It's going to go away in iOS 9, though, so maybe not:
