Installation en mode ferme
4 février 2011, parLe mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...) -

mp4 video rotation metadata removal
6 mars 2019, par Horst FiedlerUsing ffmpeg to remove rotate metadata works but output is little bit confusing as Metadata : rotate : 90 still appears in output section.

Generate mp4 from m3u8 with EXT-X-START (FFMPEG)
26 février 2019, par KPS1994I’m trying to generate a MP4 from a m3u8 playlist file using FFMPEG. The format of the file is as follows :
#EXTM3U
#EXT-X-VERSION:7
#EXT-X-TARGETDURATION:607.0
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-MAP:URI=/path_to_mp4/2019-02-25_09-55-07.mp4
#EXT-X-START:TIME-OFFSET=100
#EXTINF:600.0,
/path_to_m4s/2019-02-25_11-35-18.m4s
#EXTINF:597.64,
/path_to_m4s/2019-02-25_11-45-18.m4s
#EXTINF:600.0,
/path_to_m4s/2019-02-25_11-55-18.m4s
#EXT-X-ENDLISTIn the example above, each m4s chunk is 10 minutes long, but FFMPEG completely ignores the
#EXT-X-START:TIME-OFFSET
flag. Hence generating a video that is 30 minutes long as opposed to 29 minutes and 20 seconds.Any help on how to directly convert the m3u8 file would be most appreciated. (if there is a better tool than FFMEPG, then I am willing to try.)

Unable to playback hardware encoded H.264 to RED5 server using FFmpeg
26 février 2019, par LesI have a USB camera that is capable of H.264 on-board compression. I use the following FFmpeg command line to grab the encoded H.264 from the camera and put it in a ’flv’ container :
ffmpeg -y -f dshow -vcodec h264 -i video="USB Camera" -vcodec copy -copyinkf -f flv c:\temp\test.flv
This works as expected and I can view the video using VLC no problem. Following this principle I then attempt to stream to a RED5 server using the following command :
ffmpeg -y -f dshow -vcodec h264 -i video="USB Camera" -vcodec copy -copyinkf -f flv rtmp://192.168.75.34/live/livestream
The RED5 server detects the stream but I am unable to connect to it and view it using my basic Python program.
If I do the same thing but use FFmpeg to carry out H.264 encoding of the default capture pin (MJPEG), it will stream correctly.
I’m not sure if there is some flag in the command line that I might be missing ? Any help with this issue would be much appreciated.
Here is the log output from the second FFmpeg command :
C :\ffmpeg-latest-20190219\ffmpeg-static\bin>ffmpeg -y -f dshow -vcodec h264 -i video="USB Camera" -vcodec copy -copyinkf -f flv rtmp ://192.168.75.176/live/livestream"
