vtdec: expose kVTDecodeFrame_1xRealTimePlayback
Last modified: 2018-11-03 13:39:02 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: https://developer.apple.com/library/prerelease/ios/releasenotes/General/iOS90APIDiffs/modules/VideoToolbox.html
