    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.

  • FFmpeg stops encoding after x minutes when using Mjpeg

    31 janvier 2018, par Rune Aspvik

    I’m using ffmpeg in a node application with this command :

    ffmpeg -seekable 0 -i http://127.0.0.1:8100/Mjpeg/1?authToken=xxx -video_size 1280x720 -r 30 -pix_fmt yuv420p -y D:\Video\pflyers\test.mp4

    The encoding would stop after 28:53 every time. After some reading I figured I had to spawn the child instead of exec because of the large sterr output.

    Before doing that I wanted to see if that was in fact the issue so I tried doing :

    -nostats -hide_banner -loglevel panic

    to avoid the large output to sterr. FFmpeg still stopped after 28:53. Further I tried to write the sterr to log.txt instead of using the above code. I did so adding this to the end :

    2> log.txt

    Still it would stop at 28:53.

    Finally I tried running the command in cmd.exe resulting in the encoding stopping at 29:14.

    What I realized comparing the outputs from ffmpeg run from node and run from cmd.exe was that the encoding stopped when the log.txt reached 388kB.

    How can I fix this ?

    Here’s the full output :

    C:\Users\VossVind>ffmpeg -seekable 0 -i http://127.0.0.1:8100/Mjpeg/1?authToken=xxx -video_size 1280x720 -r 30 -pix_fmt yuv420p -y D:\Video\pflyers\test.mp4
