  • 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.

  • FFmpeg, timecode audio input, overlay

    9 mai 2015, par Wayde

    Good Morning !
    So i have been playing around with FFMpeg the last few days it seems rather amazing. I do have one challenege i am trying to over come. I like FFMpeg because it is command line and i will be able to script most of the things i want to do.
    Here is my Challenge, We run the same shows week after week, and timecode is used for ALL our automation, lighting, camera cues, sound and so on. I want to be able to record the shows with the timecode burnt in, keep in mind this audio timecode input does start and stop during the shows, therefor it cannot be part of the video stream.

    The Setup, Windows 7, Blackmagic DeckLink SDI Capture card, timecode in via Line In.

    Now, i dont mind if this overlay of timecode is a post process after being recorded as the audio input of timecode can be recorded as an audio stream and removed once the burn in has been done.

    I have searched and searched but yet to find a simple easy way to do this.

    Thank you.

  • Encoding VP9 with ffmpeg

    26 avril 2020, par blackirishman

    I am encoding a video stream from a Decklink card to Google's VP9. I am currently running a keyframe every frame. This produces the most consistent live streaming encodes. If I increase my keyframes to every 24 or 48 (2 seconds), my quality goes up, but I see encode artifacts at every scene change that slowly disappear as the scene settles. Is there a way to minimize the artifacting on scene change ?

    



    ./ffmpeg \
-format_code 23ps \
-f decklink \
-i "DeckLink HD Extreme 3" \

  • Sending BlackMagic DeckLink Studio 4K over RTMP streams with FFmpeg

    17 novembre 2017, par im dumb

    I’m trying to send a stream of video that’s coming into a BlackMagic DeckLink Studio 4K capture card over a few different RTMP streams at once with FFmpeg. The command that I am doing it with is this :

    ffmpeg -re -format_code Hi59 -f decklink -i 'DeckLink Studio 4K' -map 0 -flags +global_header -vcodec libx264 -crf 25 -preset medium -pix_fmt yuv422p -acodec aac -f tee "[f=flv]rtmp://ip1/live/test|[f=flv]rtmp://ip2/live/test.

    However, whenever I send this video out, I just get color bars when looking at the stream. I tried using a different video source (the testsrc supplied by FFmpeg), and that sends out fine over RTMP to multiple stream destinations.

    Is there something weird with how tee and the decklink stuff work in FFmpeg ? Or is there an issue with my command ?
