Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...) -

Is there a way to horizontal flip video captured from flutter front camera
5 mai 2024, par JoyJoyBasically, I'm trying to flip video horizontally after capturing it from flutter front camera. So I start recording, stop recording, flip the video and pass it to another page. I'm fairly new and would appreciate any assistance as my code isn't working


I've tried doing so using the new ffmpeg_kit flutter


Future<void> flipVideo(String inputPath, String outputPath) async{
final ffmpegCommand = "-i $inputPath -vf hflip $outputPath";
final session = FFmpegKit.executeAsync(ffmpegCommand);
await session.then((session) async {
 final returnCode = await session.getReturnCode();
 if (ReturnCode.isSuccess(returnCode)) {
 print('Video flipping successful');
 } else {
 print('Video flipping failed: ${session.getAllLogs()}');
 }
});}

void stopVideoRecording() async {
XFile videopath = await cameraController.stopVideoRecording();

try {
 final Directory appDocDir = await 
 getApplicationDocumentsDirectory();
 final String outputDirectory = appDocDir.path;
 final String timeStamp = DateTime.now().millisecondsSinceEpoch.toString();
 final String outputPath = '$outputDirectory/flipped_video_$timeStamp.mp4';

 await flipVideo(videopath.path, outputPath);

 // Once completed,
 Navigator.push(
 context,
 MaterialPageRoute(
 builder: (builder) => VideoViewPage(
 path: File(outputPath),
 fromFrontCamera: iscamerafront,
 flash: flash,
 )));
 print('Video flipping completed');
} catch (e) {
 print('Error flipping video: $e');
}
</void>

How to suspend and resume ffmpeg during encoding ?
10 janvier, par guidop21I am using FFMPEG to split a video into many 60 second video clips using a camera with the following command :


ffmpeg -f dshow -rtbufsize 2000M -i video="Game Capture HD60 S (Video) (#01)" -preset slow -codec:a libfdk_aac -b:a 128k -codec:v libx264
-pix_fmt yuv420p -b:v 1000k -minrate 500k -maxrate 2000k -bufsize 2000k -vf scale=854:480 -f segment -segment_time 60 -reset_timestamps 1 -flush_packets 1 "C:\Program Files (x86)\ffmpeg\test\clips\testfile_%02d.mp4"


I would also like to be able to do suspend and resume.
How can I do ?
Thank you

How can I get audio in my ffmpeg stream to nginx rtmp server ?
26 novembre 2013, par Conor PatrickI currently have a nginx server setup with the rtmp plugin for video streaming. I'm streaming to it with ffmpeg and then displaying the stream on a web browser with adobe flash player.
I have the video streaming successfully but I have not been able to get audio.
This is the ffmpeg command I use to start the stream
ffmpeg -f video4linux2 -s 320x240 -r 16 -i /dev/video0 -f alsa -i hw:0 -an -f flv rtmp://123.456.789.51:31002/rover/mystreamThe stream then goes to nginx which is running on this conf file
worker_processes 1;
error_log logs/user/error.log debug;
events {
worker_connections 1024;
}
rtmp {
server {
listen 31002;
application rover {
live on;
#meta copy;
#interleave on;
allow publish all;
allow play all;
hls on;
#record keyframes;
#record_path /tmp;
#record_max_size 128K;
#record_interval 30s;
#record_suffix .this.is.flv;
#on_publish http://localhost:8080/publish;
#on_play http://localhost:8080/play;
#on_record_done http://localhost:8080/record_done;
}
}
}
http {
server {
listen 26360;
location /stat {
rtmp_stat all;
rtmp_stat_stylesheet stat.xsl;
}
location /stat.xsl {
root nginx-rtmp-module-master/;
}
location /control {
rtmp_control all;
}
#location /publish {
# return 201;
#}
#location /play {
# return 202;
#}
#location /record_done {
# return 203;
#}
location /rtmp-publisher {
root /path/to/test;
}
location / {
root nginx-rtmp-module-master/test/www;
}
}
}I then access the stream from a browser using this set up for the adobe flash player and strobe media player.
Could I get some suggestions as to how I couldn't be getting audio ? I'm streaming video from my webcam and specifying audio from my mic.
