  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • The frame count getted from FFmpeg is different from its splitting action result ?

    21 février 2020, par vividlipi

    I had executed these two commands, and I got confused by its unconsistent result.

    1. I got frame count through the command following :

      ffprobe -v error -count_frames -select_streams v:0 -show_entries stream=nb_read_frames -of default=nokey=1:noprint_wrappers=1 FPS30-536-CFR.mp4

      The result is 536.

    2. I fetched every frame and saved it to a directory :

      ffmpeg -i FPS30-536-CFR.mp4 ./frames/out%04d.jpg

      I got 537 pictures in the ./frames directory which numbers form 0001.jpg to 0537.jpg

    I had tried another video, the two results are maintained the same.

    Please give me some hints, thank you very much.

    Here is the video.

  • ffmpeg options to stream to Youtube

    24 octobre 2022, par David Goncalves

    Please bear with me as I don't really understand most of the commands behind ffmpeg.

    


    I am using this code to live stream from a raspberry 4B with a USB Logitech C920 to YouTube :
ffmpeg -re -f s16le -i /dev/zero -f v4l2 -thread_queue_size 512 -codec:v h264 -s 1920x1080 -i /dev/video0 -codec:v copy -acodec aac -b:v 128k -g 60 -f flv rtmp ://a.rtmp.youtube.com/live2/[key]

    


    The streaming works but I get the following error in the command line :
Non-monotonous DTS in output stream 0:0 ; previous : 0, current : -167 ; changing to 0. This may result in incorrect timestamps in the output file.

    


    I also get this error in Youtube studio :
Please use a keyframe frequency of four seconds or less. Currently, keyframes are not being sent often enough, which can cause buffering. The current keyframe frequency is 8.0 seconds. Note that ingestion errors can cause incorrect GOP (group of pictures) sizes.
Any help ?
