Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

Create audio/video, audio only, and video only HLS playlist version of the same media file
15 avril 2020, par Kevin PaekI have a
media.mp4file.


Currently I convert it to an HLS playlist with this command :



ffmpeg -y -i \
 "media.mp4" \
 -g 48 -sc_threshold 0 \
 -profile:v baseline -level:v 3.0 -pix_fmt yuv420p \
 -map 0:0 -map 0:1 -map 0:0 -map 0:1 \

 -map 0:0 -map 0:1 -map 0:0 -map 0:1 \
 -c copy \

 -var_stream_map "v:0,a:0 v:1,a:1 v:2,a:2 v:3,a:3 v:4,a:4 v:5,a:5" \

 -hls_flags split_by_time+round_durations \
 -start_number 1 \
 -hls_segment_filename "av/%v/%02d.ts" \
 "av/%v/prog_index.m3u8"



I can create audio only and video only version with the
-anand-vnflags, but it would convert the file 3 times.


Is there a way I can create all three versions with only 1 conversion ?



I couldn't figure out a way to convert the resulting
master.m3u8into and audio only and video only version.
Also tried creating aconverted_media.mp4then using that to just copy the audio and video streams and just make the 3 playlists, but that didn't work either.


Any help appreciated.

Live streaming HLS on Red 5 Media Server on Windows Server
31 juillet 2013, par user1516711I am trying to develop a streaming server using Red 5 on Windows Server that would have two clients, a web app running on Windows 8 PCs and an iOS app.
The problem I'm facing is that iOS only supports HLS and Red 5 only supports RTSP/RTMP, so I need to convert incoming streams from HLS to RTSP/RTMP and outgoing streams from RTMP/RTSP to HLS using FFMPEG commands. How would I go about this ? Should I modify the Red 5 server code or is there a better alternative ?

C# FFMPEG : Code bugs out and stops producing media files
24 mai 2020, par HamezI've made a joke program in C# that uses ffmpeg to edit videos with different effects such as stuttering. I've finished 3 effects so far and each of them work on their own but as soon as I put one after another
e.g. fx.CrashStutter(0, 2); fx.CrashBeep(2, 2); fx.Wow(4, 2);
The code breaks and no longer produces photo/video files but once I stop debugging the file it was supposed to be processing appears. I've used a system where it loops over trying to execute a command to create a text file as a marker for when ffmpeg is done processing a file. The debug console also repeatedly says "The process tried to write to a nonexistent pipe."


Here's the code for all 3 effects :



public void Wow(double start, double duration)
 {
 if (fxstart == true)
 {
 //MessageBox.Show("WowFX Duration" + duration);
 string folderName = ("W_s" + start);

 FXcmd.StandardInput.WriteLine("ffmpeg -ss " + start + " -t " + (duration / 6) + " -i " + source + " a.mp4");
 //wait until a.mp4 appears
 while (File.Exists("FxSource(Temporary)\\" + folderName + "\\a.txt") == false)

 /*aha got a live one!*/FXcmd.StandardInput.WriteLine(" echo a > a.txt");
 System.Threading.Thread.Sleep(1500);
 }
 FXcmd.StandardInput.WriteLine("ffmpeg -i a.mp4 -vf reverse -af areverse b.mp4");
