  • 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 (...)

  • swscale : don't omit ff_sws_init_range_convert for high-bit

    swscale : don't omit ff_sws_init_range_convert for high-bit

    This was a complete hack seemingly designed to work around a different
    
bug, which was fixed in the previous commit. As such, there is no more
    
reason not to do this, as it simply breaks changing color range in
    
sws_setColorspaceDetails for no reason.

  • Doing parallel ffmpeg conversions on dozens of servers simultaneously. Is there a better way ? [on hold]

    22 mai 2019, par user15063

    Im currently working on a fairly large site, that requires several thousands of files to be encoded with ffmpeg into flash format (along with thumbnails creation, mobile file encoding). Average encode runs for about 5-15 minutes, as they are fairly large source files. After the job is complete, the outputs need to be shuttled to different servers (flash file to one box, thumbnails to another, mobile file to another, and original file to another).

    During this processes (which is 13 steps at this point) there is a LOT that can go wrong, at any given time (bad files, stuck encodes, network latency, dying servers, spiking lead), so error handling is a bitch.

    Are there any existing solutions for this type of work ? Or do I have to just keep tweaking my homebrew scripts ?

  • Record with uncompressed format for faster cutting with ffmpeg

    23 août 2020, par Alex

    I am having difficulty cutting videos accurately.

    


    This is the current command I am using. The problem with this command is that
I have to re-encode the data.

    


    ffmpeg -i file_name.webm -ss 00:00:00 -strict -2 -to 00:00:00 new_file_name_3.webm


    


    The codec I am using is VP9 with the webm container (docs)

    


    This works fine, but it could take longer for large videos.

    


    I would like to know if there is a way to record with ffmpeg in an uncompressed format which would
allow for accurate cutting without needing to re-encode the data. Once all of the cutting work is
complete I code stick it all together then do a final encoding.

    


    Is this an option in ffmpeg ? Is so how can I accomplish it ?
