  • 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 (...)

  • Live stream videos on YouTube with ffmpeg ?

    30 janvier 2021, par Manuservus

    What the program should do :

    


    It should download a video from an URL.

    


    Then put the video into a streaming interface (on the right side there should be the live chat from YouTube, in the middle, there should be the downloaded video).

    


    Next stream it live to YouTube.

    


    The process should repeat endless times.

    


    Download video from URL —> Stream it live to YouTube in a streaming interface -> repeat the whole process.

    


    Is this even possible in Python ? If yes how ?

    


    I would appreciate any help !

    


    PS : The stream should run smoothly without a break. That means : As soon as a video is finished, the next comes straight away.

    


  • libFLAC/stream_decoder : Fix double free

    libFLAC/stream_decoder : Fix double free

    The american-fuzzy-lop fuzzer found a couple of instances of double
    
free() resulting from commit 15a9062609.
    

    The problematic free() were the ones associated with use of the
    
safe_realloc_mul_2op_() function which can call realloc(ptr,0) which
    
according to the realloc manpage is already an implicit free().

  • FFMPEG stream video to Youtube Live

    13 juin 2022, par BlessedHIT

    I have a mov file and I'm using ffmpeg to stream it to youtube live using the following command,

    


    ffmpeg -re -i "episode.mov" -pix_fmt yuvj420p -x264-params keyint=48:min-keyint=48:scenecut=-1 -b:v 4500k -b:a 128k -ar 44100 -acodec aac -vcodec libx264 -preset medium -crf 28 -threads 4 -f flv "rtmp://a.rtmp.youtube.com/live2/YOUTUBE.LIVESTREAM.KEY"


    


    But im getting the following message on youtube,

    


    YouTube is not receiving enough video to maintain smooth streaming. As such, viewers will experience buffering


    


    My ffmpeg output showed my bitrate being between 800 - 1000 mbps, way lower than what i have specified in my ffmpeg command.

    


    I am using a not so powerful virtual machine, and so i thought this might be why i am not getting the desired bitrate.

    


    To overcome my hardware limitations, I then decided to encode the file for streaming using this command :

    


    ffmpeg -i episode.mov -c:v libx264 -preset medium -b:v 4500k -maxrate 4500k -bufsize 6000k -vf "scale=1280:-1,format=yuv420p" -g 50 -c:a aac -b:a 128k -ac 2 -ar 44100 episode.flv


    


    Then I stream copy the file using :

    


    ffmpeg -re -i episode.flv -c copy -f flv "rtmp://a.rtmp.youtube.com/live2/YOUTUBE.LIVESTREAM.KEY"


    


    And that seems to give me a stream that youtube is happy with.

    


    My question is, is there a way I can rewrite my ffmpeg command to livestream with the desired bitrate without needing to first encode my mov to another file or is adding more memory the only way forward here ?
