Running a few tests to see if there's any practical value in using a RPI4 to generate h.264s from camera originals using FFMpeg.
So far it's not exactly overwhelming: > ffmpeg -i path/to/source.mp4 -b:v 9000k -vf scale=1280:720,format=yuv420p > path/to/dest.mp4 ran at about 25% of real time (compared to a Mac that ran the same file at >4x real time) An attempt to do some hardware acceleration... > ffmpeg -i path/to/source.mp4 -c:v h264_omx -b:v 9000k -vf > scale=1280:720,format=yuv420p path/to/dest.mp4 Gave the exact same same results I don't know I would expect more from a $50 computer -- the fact that it works at all is already impressive -- but I thought I'd ask if anyone has any ideas on how to get more speed out of the little thing. _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
