I grabbed the ffmpeg command from the log output in order to be able to run it directly (I include debug-level logging at the end): Without hardware acceleration, my RPI4 manages stutter-free playback but get very hot very quickly.Īfter following these instructions to set up HWA, unfortunately the underlying ffmpeg command seems to hang – it doesn't output any encode/decode information, or any transcoded files. I've noticed there is also h264_vaapi that I cannot get working at all, but I think that is for the camera device only.Hi all, I'm having a problem transcoding H.265 to H.264 to play on a Chromecast. Failed to set maximum video quantizer scale: Invalid argumentĬan anyone point me in the right direction? Is what I'm doing feasible? Is h264_v4l2m2m only for camera devices? If h264_omx is deprecated, than how could I do this in future?
