  • ffmpeg output speed writing to udp vs fifo on ec2 linux

    20 janvier 2017, par art vanderlay

    I 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
    Art
