  • 24 cores, 25 ffmpeg session - cpu looks good but load average high

    9 août 2012, par thevoipman

    I don't know if it's my script or just the system itself, but I definitely don't want to take anything down.

    I am running a centos 6.3 64bit with about 25 sessions of ffmpeg encoding

    1. I am trying to speed up ffmpeg encoding, but it seems like whatever ram or cpu I have, the encoding process still take very long. I have used -threads 0 or even -threads 16 to see if it speed up but it doesn't.

    2. My load average is very high, how can I lower this without terminating ffmpeg tasks ?

  • How to parse ffmpeg info in PHP ?

    29 mai 2013, par Jizbo Jonez

    How does one go about getting specific pieces of information, like the 'duration' from the output of ffmpeg -i /var/thismovie.avi ?

    I need frame height, frame width, duration of movie and frame rate. All of these are in the out put of the above command but how do i get the bits i need individually and put them in a variable in PHP ?

    I've given up on trying to install ffmpeg-php which is what I used before this to do the same job.

    Thanks

    ffmpeg -i /var/thismovie.avi produce an output like this

  • Write webcam video with avconv

    31 juillet 2012, par Jones

    Have problem to write video avi with avconv

    I try using

    avconv -v debug -f video4linux2 -i /dev/video1 frontal.avi

    but video not correct. I see this line [video4linux2 @ 0x8100b00] The v4l2 frame is 8160 bytes, but 614400 bytes are expected and I don't identify options to correct this.
