    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • How to play HDR10 videos using ffplay and ffmpeg ?

    6 janvier 2023, par befandy

    I'm trying to play on Windows a HDR10 video. My display support 10 bits HDR content.
The command that I'm using to play the HDR10 video is the following.
ffplay -sws_flags print_info -i video.mp4

    


    But the output looks washed out.

    


    the log are the following :

    With the help of '-sws_flags print_info' flag we can see that there is a downscaling happening from 10 bits to 8 bits "yuv420p10le -> yuv420p"

    


    I have try to play the video using VLC and it is working fine on my display : colour are vivid and display bright.

    


    I have also try to decode first the video and then past metadata directly to ffplay as follow.
Decoding to yuv format with : ffmpeg -i video.mp4 video.yuv
Then play yuv file : ffplay -framerate 60 -video_size 3840x2160 -pixel_format yuv420p10le -color_range tv -color_trc smpte2084 -color_primaries bt2020 -colorspace bt2020nc -i video.yuv

    


    But the result is the same washed out color and "yuv420p10le -> yuv420p" conversion

    


    Is there a way to play a HDR video (encoded or decoded stream) with ffplay ?

    


  • My (FFMPEG issue ) RTMP server(freebsd) wont let me hear video when I play a huge file over the server itself :/

    19 avril 2021, par Engi Gang

    Hey my name is Alisha from Norway im trying to get my RTMP server working the thing is that it works just fine but I just cant stream over it with ffmpeg I can stream to it on OBS and it works fine, but I am trying to a website where people could watch old public domain movies from the 1950 some of the films are actually pretty big lol.... anyways I detailed bellow more

    


    rm -rf /mnt/hls/loool && ffmpeg -re -i "$file" -c:v libx264 -c:a aac -b:v 300k -b:a 95k -f flv -flvflags no_duration_filesize rtmp ://lambright.xyz:1935/live/loool

    


    any work around I literally cant play the audio :( I can only hear (my source file is an MKV and 3gb )

    


    Note I had a smaller mp4 file and it did played the audio, the video isnt even playable in chrome but on VLC it is, but only a small file worked fine... its fine when I stream from my pc, but whats the point I am trying to set up my vintage 1950 serverbox :') trying to build a nice website where users could watch neat and decent old movies that are public domain if you wonder :/

    


    Another note when I am trying to play it on my iphone safari browser it does actually play parts but audio is super corrupted like you hear the audio sometimes :((

    


    rtmp {
    server {
        listen 1935; # Listen on standard RTMP port
        chunk_size 4000;

        application live {
            allow play all;
            live on;
            record off;
            hls on;
            hls_nested on;
            hls_path /mnt/hls/;
            hls_fragment 2s;
        }
        
    }
}


    


  • mov and mp4 files to play in browser

    5 novembre 2016, par Pranav Unde

    Currently I am playing with html5 video tag and database video files. I have couple of records in database that contains mov & mp4 files. HTML5 video tag supports mp4 but what about mov files ? I am trying to use external libraries but it not helps .. might be my implementation is wrong ...

    Can we get any library that converts mov to mp4 or browser that support ONLINE rather than saving it anywhere ... ?

    Also can I get any code snippet for handbrake source code implementation so that I can try for it.
