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.

Forwarding rtsp feed from one local port to another
11 août 2021, par Thabet Sabhaso let's say I have an rtsp server running on port 554, and when a certain command is received, i want the rtsp server to start forwarding the feed (using rtsp+tcp) to a service running on the same machine but on port 553 (Linux OS), is that possible via a CL command, or do I have to use something like ffmpeg ?


currently this is what is being used, but I feel like this is redundant since all we're doing is just forwarding the feed to another port on the same machine.


const ffmpegOptions = [
"-rtsp_transport", "tcp",
"-i", "rtsp://127.0.0.1:554",
"-codec", "copy",
"-f", "rtsp",
"-rtsp_transport", "tcp",
"rtsp://127.0.0.1:553"
]

const myProcess = spawn('ffmpeg', ffmpegOptions);



Thanks.

How to manually reset the offset of an mp4 video created from m4s files ?
12 août 2020, par natdevI'm building a service that combine
.m4s
files (from a dash stream) to amp4
video.

I have some samplem4s
files from a random point in time of a stream,

usingffmpeg
on those file + the init file does the job.

cat init.mp4 032.m4s 033.m4s 034.m4s > output.mp4



I have tried concating the
m4s
files to themp4
init file and I manage to play the video,

but there is an offset from the encoded video segments.

I guess
ffmpeg
does reset that somehow, and I was wondering how can I reset that offset as well ?

Having a little bit of experience withdash
, I know that there is a field namepresentationTimeOffset
that is responsible to set the offset.
