  • 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

  • ffmpeg : How to change video duration (slow-down or speed-up) to exact value ?

    2 février 2017, par Moo

    I have miltiple videos with different durations and need to always set it to be exactly 10 seconds.

    I know that I can use -filter:v "setpts=speed*duration" but is there any way to make a universal one-line function to convert any-duration video to 10 seconds video ?
