ffmpeg output speed writing to udp vs fifo on ec2 linux
20 janvier 2017, par art vanderlayI would like to find an approach to measure the speed of ffmpeg writing output to udp vs fifo.
For this case it would be video + audio.
Is there a internal timing method available to do such a measurement ?
Is there a prevailing agreement that one approach is known to be faster than the other.
Thx
