H264 Hardware Decoding #12

Open oarnold opened 6 years ago

oarnold commented 6 years ago

I am trying to enable hardware decoding for the H264 video frames, sent from a drone. Unfortunately this does not seem to work. I added the line "[[VideoPreviewer instance] setEnableHardwareDecode:YES];" before "[[VideoPreviewer instance] start];", in the file "DJICameraViewController.m" . But this will only show the following log message: "FPVDemo[579:506030] can not find idr path func". The application then falls back to the software decoder.

I also posted a topic on the DJI forum, a while ago: http://forum.dev.dji.com/forum.php?mod=viewthread&tid=32401

Steps to reproduce the bug or crash issues

Set enableHardwareDecode to "YES". Start app and wait until preview is shown.

Any updates on this? I still see the app falling back to the software decoder.
