  • 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 (...)

  • Mixing audio, given timestamps. How to do it efficiently ?

    2 août 2021, par Evil

    I have two stereo sounds, 1.wav and 2.wav, these sounds are less than 1 second long and list of timestamps (miliseconds from start of recording). Recording of pure video (recording.mp4) is several hours long and there are thousands (20 000 - 30 000) of timestamps per sounds.

    


    I want to convert list of timestamps and sounds into one recording, merging it with video. The part of merging audio with video is easy with ffmpeg, so this is not part of the question.

    


    The list of timestamps is tsv, for example :

    


    


    1201\t1.wav
    
1501\t2.wav
1603\t1.wav
    
and so on, up to 50 000

    


    


    I can convert it to anything, I am generating this file.

    


    I have seen mixing sound with padding and mixing audio to existing video, but I have to batch process a lots of samples, running sox that many times is not feasible. Mere onstructing input for ffmpeg or sox is a cumbersome task.

    


    I do not use any effects on sounds. There is no explicit support in sox to take one input and play it multiple times (echo / echos destroys the material). Also creating padding or delay takes a lot of time. FFMPEG also needs long query to make it happen.

    


    Since muxing two files is easy, I have tried to record two sounds separately, but still it takes a lot of time to process.

    


    Is there simpler / faster way ?

  • ffmpeg vs mencoder

    2 février 2013, par Jonah Braun

    I'm doing a bunch of video encoding for a variety of devices and platforms. I've bounced back and forth a few times between mencoder and ffmpeg. Which do you recommend and why ?

    Side question : From googling it seems that mencoder uses ffmpeg. Does it do this all the time or only when it deems necessary ?
