RPI 4B > How much memory did you split to video? I was unaware of the option, so it was set to the default (64mb). Thanks for the tip. Just set it to the 512mb, re-booted and tested the speed again ( max for RPI according to the raspberrypi site <https://www.raspberrypi.org/documentation/configuration/config-txt/memory.md> ). Unfortunately, no improvement in the speed. The same page above that specifies 512mb is the max, also specifies 1024mb is an option. Tried that as well.

I actually don't necessarily need to scale the output, as long as I can control the bit rate. It's just that FFmpeg returns an error without it... (according to the subsequent response by Carl, the reason is the hardware can't encode 4k.) > > Regards, > Ted Park _______________________________________________ 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".
