Support audio et vidéo HTML5
10 avril 2011MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...) -
Configuration spécifique d’Apache
4 février 2011, parModules spécifiques
Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

Because the two cameras have a same device name, I couldn't stream two videos using this simple command at a same time :
ffplay -f dshow -i video=Microsoft® LifeCam Studio(TM)
.

So I used pin names following the ffmpeg dshow example.
The only thing I could check wasCould not find video device with name [video=~~pin name~~] among source devices of type video.



What
ffplay
command makes enable to stream both videos ?

Merging two audio files in Android using FFMPEG
1er juillet 2021, par JeremyI'm working on an application that takes two audio files, and merges them into the respected channels. The way they are being equalized are not as good as I had hoped, So I want to adjust the volume of each file during the mixing phase. I've seen a couple of examples online, like this, this, and
[this][3]
.. but none of them are working for me. Can someone direct me in the right direction with this ? Much appreciation !


I am using this library to execute : https://github.com/WritingMinds/ffmpeg-android-java



Here is my code (EDIT)



String files = "-i " + mVoiceFile.getAbsolutePath() + " -i " + mBeatFile.getAbsolutePath();
String filter = "-filter_complex [0:a]volume=0.99[a1];[1:a]volume=0.3[a2][a1][a2]amerge=inputs=2,volume=1.3,pan=stereo|c0



enter code here



and here are my errors from running.

FFmpeg concat in android
13 avril 2018, par fvnI have trying to concat multiple videos (mp4 or mov)on Android Studio using FFMPEG. I have managed to get vidoes in an arrayList and their path like this :
private List<string> getSelectedVideos(Intent data) {
List<string> result = new ArrayList<>();
ClipData clipData = data.getClipData();
if(clipData != null) {
for(int i=0;icode></string></string>I have looked online on how to concat vidoes using FFMPEG https://trac.ffmpeg.org/wiki/Concatenate
However I’m not sure how to do it using Android studio. Any help would be much appreciated.
