  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • 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

  • why would ffmpeg rotate 2nd video on concatenation when I don't want it to or seemingly ask for it ?

    10 janvier 2023, par Pompey Magnus

    here is the command I run :

    


    ffmpeg -f concat -an -i ./files.txt ztestout.mp4


    


    I have about 5 videos, but just to test I did with two.
the 2nd video gets flipped upside down, even though opening each video in VLC opens and plays them correctly.

    


    Any ideas why it would do that ? Is the metadata wrong in the video ? I took all the videos I'm trying to concat with the same android phone.

    


    output below, and I noticed its says rotation zero degrees :
