Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.

ffmpeg switch inputs / mapping on-the-fly / while recording
7 juin 2020, par SuuuehgiI have a rtsp video-source
stream1
and an audio source I currently merge and send to a rtmp-server using :


stream1="rtsp://streamurl1"

/usr/bin/ffmpeg \
 [...]
 -i "$stream1" \
 [...]
 -itsoffset $AUDIOVIDEOOFFSET \
 -f pulse \
 -i default \
 [...]
 -vcodec copy \
 -map 0:v -map 1:a \
 [...]
 -f flv "rtmp://streamingserver"






I would now like to add a second video source
stream2
and switch betweenstream1
andstream2
back and forth without interrupting the audio. Both streams are identical / come from identical cameras.




Is there any sane way to do this with
ffmpeg
? Or how would you recommend doing it ?


Just stopping the process and restarting it using
stream2
instead ofstream1
works but results in several seconds outage on the stream and is the current worst case scenario I would like to improve.

Dynamically Extending FFMPEG Playlist for Continuous Video Streaming
3 août 2023, par dumbQuestionsI am trying to create a seamless FFMPEG playlist so I can add new videos without interrupting the stream. Currently, I'm using the following command :


ffmpeg -re -f concat -safe 0 -i playlist.txt -c copy -f flv "${INPUT_URL}"


The initial playlist works fine, but when I try to append new files to it, the streaming stops and the newly added files don't seem to affect the output.


I've tried manually editing the playlist.txt file and adding new video files to it while streaming, but it seems like FFMPEG doesn't automatically detect the changes and continues the streaming seamlessly. I also attempted using the
-concat
option, but it didn't work as expected.

Is there a proper way to dynamically extend the FFMPEG playlist while maintaining continuous video streaming, or a way to continuously stream new clips one after the other without interruptions ? Any insights or suggestions on how to achieve this would be greatly appreciated. Thanks in advance !

Max MP4 H264 Header Size
22 octobre 2016, par SetVI have a requirement to cut a MP4 container H264 video encoded file into header part and content part.
Instead of dwelling into details of the header, I want to split the file with a max MP4 video header limit.
Is there any such limit exist ? Does splitting initial 2/4 MB from the file will hold the header completely ?
The requirement is, if the content part of the file is accessible, the video should not be recreated. Is splitting the file into header and content will help ?
