Recording RTSP stream with fragmentation.

[gawcio90]

Hi!

I have problem with fragmentation. I don't know how can I do this.
Right now I use:

Code: Select all

cvlc rtsp://address --sout "#transcode{}:duplicate{dst=std{access=file,mux=ts,dst={/mnt/record/test.h264}}}"

I want to fragment this stream every single hour. Like this:
record001
record002
record003

One file should be 1h of stream.

How can I do this?

Regards.

Hello,

I'm sorry I do not have the answer to your post but I am trying to do the exact same thing. Just wondering if you have found the solution and could post how to do it?

Thanks,

You could try to use the livehttp module to do this. Normally you use it to segment a stream for HTTP Live streaming compatibility. Such segments usually have a length of 10 seconds or so. In your case a segment would need to be 1 hour in seconds being 3600 seconds. This should be achieved with seglen.

Basic idea:

Code: Select all

access=livehttp{seglen=3600,no-delsegs,numsegs=XX,index=/path/index.m3u8,index-url=/path/fileSequence####.ts}

Here is a complete chain:

Code: Select all

cvlc rtsp://address --sout='#transcode{width=1280,height=720,fps=25,vcodec=h264,vb=4096,venc=x264{aud,profile=baseline,level=30,keyint=30,ref=1},acodec=mp3,ab=96}:std{access=livehttp{seglen=3600,no-delsegs,numsegs=10,index=/your/path/to/prog_index.m3u8,index-url=fileSequence######.ts},mux=ts{use-key-frames},dst=/your/path/to/fileSequence######.ts}'

I am not sure if this is possible. Haven't tried producing segments this long. Try it. I left my transcoding settings intact for you to copy or leave out if needed.

Thank you for the response Crackstone.

I am getting the error no such file or directory. I am obviously not making the correct path to the output folder. All I did to your complete chain was add my rtsp address and tried to make a correct path.

I have a folder inside my 'home' folder called 'cam1'. So I changed where you had 'index=/your/path/to/prog_index.m3u8, index-url=fileSequnce######.ts}" to "index=/home/cam1/prog_index.m3u8, index-url=fileSequnce######.ts}" as well as the other location in the chain where you had me change to that same path.

Obviously I am not doing this correctly do you know how this can be done?

Thank you,
Jade

From a quick viewpoint: Is this the complete path to your index file (/home/cam1/prog_index.m3u8)? Check if you can reach your path if you do a change directory to it via simple terminal e.g.: cd /home/cam1/

Otherwise provide your log statements via http://pastebin.com/
