Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

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 (...) -
Encoding and processing into web-friendly formats
13 avril 2011, parMediaSPIP automatically converts uploaded files to internet-compatible formats.
Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
All uploaded files are stored online in their original format, so you can (...)

Fails to crop video with ratio height = width using FFMpeg on Android 7
18 avril 2018, par BabsI am using FFMpeg Android this link in our Android app
crop the video to 1:1 ratio i.e height = width
The below command works great on Android devices with Api < 24 but Fails on Api 24. I have also pasted my log analysis below, appreciate if anyone can help me fixing this issue.
public static String cropVideo(final Context context, final File file, final BaseCaptureInterface mBaseCaptureListener) {
String croppedUrl = "";
FFmpeg ffmpeg = FFmpeg.getInstance(context.getApplicationContext());
try {
croppedUrl = file.getParent() + "/Cropped_" + file.getName();
String[] cmds = {"-i", file.getAbsolutePath(), "-vf", "crop=out_h=in_w", "-threads", "5", "-preset" ,"ultrafast","-strict","-2",croppedUrl};
ffmpeg.execute(cmds, new ExecuteBinaryResponseHandler() {
@Override
public void onStart() {
Log.d(TAG, "cropVideo:onStart()");
}
@Override
public void onProgress(String message) {
Log.d(TAG, "cropVideo:onProgress(): " + message);
}
@Override
public void onFailure(String message) {
Log.d(TAG, "cropVideo:onFailure(): " + message);
Toast.makeText(context, "Failed to Crop the video", Toast.LENGTH_SHORT).show();
}
@Override
public void onSuccess(String message) {
file.delete();
mBaseCaptureListener.videoCropStatus(true);
Log.d(TAG, "cropVideo:onSuccess(): " + message);
}
@Override
public void onFinish() {
Log.d(TAG, "cropVideo:onFinish()");
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
Log.d(TAG, "cropVideo:error: " + e);
}
return croppedUrl;
}Observation : Below is the comparison of Pass and Fail logs during onProgress() of cropping. in Fail Logs, the frame initial is 0 and then abruptly jumps to 2392 also the size increases proportionately. Whereas in the Pass logs, the increase in frame and size is quite smooth.
I am wondering if my command string[] needs some changes. Please, let me know if you have any suggestions.Pass Logs :

Is there a tool to batch save video information (frame height, width, rate, etc) to video files' metadata ? [closed]
4 avril 2021, par André LevySearched all over to no avail. I had a vague recollection that MediaInfo did it, but no can do. Perhaps there's a way with ffmpeg, but all I've seen are commands to export the metadata already on the files.

ffmpeg : Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
20 novembre 2020, par AlexandreI'm experiencing troubles running ffmpeg on my synology. I'm trying to convert .avi video to mp4.



Here is the command :



ffmpeg -i vid20160623.avi -acodec libfaac -b:a 128k -vcodec mpeg4 -b:v 1200k -flags +aic+mv4 -f mp4 vid20160623.mp4

Any help will be welcome.
