Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

Upper limit on FFMPEG/libx264 frame sizes ?
22 mars 2014, par ChaoticI'm trying to use FFMPEG to transcode a video with very large frames (4096 x 4096). It's a short video - just under two minutes, but the source video file is 15.8GB. (The video is an animation designed to be projected onto planetarium domes.)
The source file is a Quicktime MOV containing uncompressed Photo-JPEG images (with audio, too). When I tell FFMPEG to transcode my MOV file into an MP4 file, it simply says :
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
Not very helpful, but yes, I've verified that all of the parameters are correct and/or defaults. In fact, if I change the requested output size to 2048x2048, then everything works just fine. That's why I suspect that there's an upper bound in the encoder.
I am kerflummoxed. Any suggestions that result in a successful transcode will be greatly appreciated. (At this point I am also willing to consider alternatives to FFMPEG.)
The Facts
I run FFMPEG from a script :
set srcFile=%1
set dstFile=%srcFile:.mov=.mp4%
ffmpeg -i %srcFile% -movflags faststart -q:a 0 -q:v 0 -pix_fmt yuv420p -sws_flags gauss -s 4096x4096 %dstFile%The Output

ffmpeg concat skips frames near end of each subclip
3 janvier 2024, par calvinusesyourcodeSo I have some video files to concat but in the resulting video the last few frames of each subclip are buggy. Imagine in the last 5 frames the first 3 frames are skipped and so at the end of each clip it seems to jitter.


It should be virtually impossible for my input videos to have any differences between them, as they were all recorded on the same iPhone and all converted with the same command :


command = [
 'ffmpeg', '-y',
 '-i', input_path,
 '-vf', 'scale=1080:1920',
 '-r', '30',
 '-c:v', 'libx264',
 output_path
 ]
subprocess.run(command, check=True)


I have tried re-encoding instead of merely copying and adding
-r 30but that doesn't seem to work.

subprocess.run(["ffmpeg", "-y", "-f", "concat", "-safe", "0", "-i", temp_textfile, "-c", "copy", output_path])


subprocess.run(["ffmpeg", "-y", "-f", "concat", "-safe", "0", "-i", temp_textfile, "-r", "30", "-c:v", "libx264", "-c:a", "aac", output_path], check=True)


Somewhere someone said to open in VLC and do a frame-by-frame, reporting that "the frames are actually there, just not visually when watching normally". In my case the frame-by-frame reveals the frames are indeed being skipped.

UPDATE : I am thinking that the way I am converting my files from .mov to .mp4 is the problem. Please suggest the best way to convert from iPhone 4k 60fps .mov files to nice 1080p 30fps .mp4 files. I know I could just use handbrake but I am trying to be a man here xD. Perhaps handbrake has a
View ffmpeg code for conversion.

Do I need multiple video files in different resolutions to use MPEG DASH ?
2 février 2023, par Gentil AlysonI'm trying to use Django REST Framework to serve .mpd files. When the user uploads a video, the server creates the MPD and the chunk files. However, I can't seem to able to make it work. I've tried using python-ffmpeg-video-streaming, but the client which is using dash.js to play the video will get only one bitrate (480p). I've also tried running this command
'ffmpeg -i {self.file.path} -map 0 -map 0 -c:a aac -c:v libx264 -b:v:0 800k -b:v:1 300k -var_stream_map "v:0,name:800k v:1,name:300k" -f dash -dash_segment_type mp4 -single_file 1 {file_dir}/dash.mpd'usingos.systemfrom Python, but then the player gets stuck at buffering.
