Les vidéos
21 avril 2011, parComme 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 (...) -

Can ffmpeg log a output of histogram and wavetransform ?
5 février 2018, par jayffmpeg has an option of showing a color histogram and a wavetransform which is from sound data on a screen.
I want to collect them as text form pushing into a log file and later can check with linux text parser tools.
For example, Assuming some of videos has a period of black screen as it plays.
Then it is easy to find out that ’when does video has a period of black ?’ or ’which video file has a period of black ?’ by YCbCr histogram log.is it possible ? I have looked ffmpeg document but couldn’t find it.

Convert Audio Files using FFMPEG in android
25 avril 2018, par Venkat MaddyI developing android application, Where I’ve asked to record the calls and convert them to WAVE(.wav) format and send to server.
I am able to successfully record and save the audio in my mobile. The recorded file mime type is 3gpp, now I want to convert this 3gpp file to wav. I tried using FFMPEG but unable to convert it. I am posting my code here, Any help would be grateful.
While Converting the recorded file from aac to wav, I’m getting below error
