  • 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.

    Why am I not getting an I-Frame every second frame ? Is there something else I can set to do enforce this ? If not, can you suggest how to do this using the mpeg4 codec. It's vital that I can extract what type of frame has been encoded during the encoding process and that I can set a specific GOP structure.

  • Webcam recording with FFmpeg through USB over UTP

    13 septembre 2021, par z32a7ul

    I'm trying to record my webcam with FFmpeg.

    


    I listed the devices with this line :

    


    ffmpeg -list_devices true -f dshow -i dummy


    


    And I test the settings with this one :

    


    ffplay -loglevel verbose -f dshow -rtbufsize 100M -video_size 1280x720 -framerate 60 -video_device_number 0 -audio_device_number 0 -i video="C922 Pro Stream Webcam":audio="Microphone (C922 Pro Stream Web"


    


    The first command outputs this :

    What can be the problem ? Is it the extender cable ? What are FFmpeg's requirement on USB cables (and extenders) ?

    


  • Merging audio at specific time with ffmpeg

    19 octobre 2015, par Deepu

    I was trying to merge audio with ffmpeg with the following command but the audio is merging at starting point.

    ffmpeg -i output-1146.mp4 -i org-EOLWAudio.mp3 -filter_complex " [0:a]atrim=start=0,asetpts=PTS-STARTPTS[aud1]; [1:a]atrim=0:250,asetpts=PTS+100/TB[aud2]; [aud1][aud2]amix=inputs=2[aout]" -map 0:v -map "[aout]" -crf 24 -pix_fmt yuv420p -c:v libx264 -c:a aac -strict -2 -ac 2 output-1246.mp4

    With this command it is merging audio streams but not specified point of time.

    I want to merge audio of a mp3 file from 0 to 250 seconds audio to video
    Starting at 4th minute to 8.10 minute.
