  • 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 (...)

    27 juin 2022, par user14809144

    I would like to crop and resize multiple videos that exist in one folder using Ffmpeg.

    


    I did it with a single video but unfortunately, I don't know how to apply it to multiple videos in one line of command.

    


    Crop ; code for single video

    


    ffmpeg -i input1.mp4 -filter:v "crop=1000:1000” output1.mp4

    


    Resize ; code for single video

    


    ffmpeg -i output1.mp4 -vf scale=512:512 -preset slow -crf 18 output2.mp4

    


    I want to crop multiple videos (more than 50 videos in one folder) to be 1000X1000 and then resize them again to be 512X512.

    


    Any help ? advice ?

    I am developing a software that use FFMPEG AVPixelFormat for images and videos. I want it to be compatible with most common pixel formats.

    


    Is there a website where I can download images/videos that have all kind of pixel formats for testing purpose (like RGBA, BGRA, YUV, Greyscale, ...) ?

    


  • Using FFMPEG to stream continuously videos files to a RTMP server

    16 avril 2017, par KKetch

    ffmpeg handles RTMP streaming as input or output, and it’s working well.

    I want to stream some videos (a dynamic playlist managed by a python script) to a RTMP server, and i’m currently doing something quite simple : streaming my videos one by one with FFMPEG to the RTMP server, however this causes a connection break every time a video end, and the stream is ready to go when the next video begins.

    I would like to stream those videos without any connection breaks continuously, then the stream could be correctly viewed.

    I use this command to stream my videos one by one to the server

    ffmpeg -re -y -i myvideo.mp4 -vcodec libx264 -b:v 600k -r 25 -s 640x360 \
    
-filter:v yadif -ab 64k -ac 1 -ar 44100 -f flv \
    
"rtmp://mystreamingserver/app/streamName"

    I looked for some workarounds over the internet for many days, and i found some people talking about using a named pipe as input in ffmpeg, I’ve tried it and it didn’t work well since ffmpeg does not only close the RTMP stream when a new video comes but also closes itself.

    Is there any way to do this ? (stream a dynamic playlist of videos with ffmpeg to RTMP server without connection breaks
