Time Lapse on Repetier-Server 0.70.0 on Raspberry Pi

BenStein

I've got Repetier-server set up and it's capturing images from mjpeg-streamer. I can step through them in the web interface. However the time lapse videos it lists in the interface are zero byte and won't play. I have ffmpeg installed, but is there a certain plugin I should be using or a setting I need to update to get it to generate proper time lapse videos? Is there a way to test or a log fine I could look at to see what's happening? Any help getting me pointed in the right direction would be appreciated..

Thanks!

If you have pi with wheezy the ffmpeg version is too old. You get a newer version on ffmpeg version that can do the conversion. You need version 1.1 or higher for video conversion to work. And you should upgrade to 0.70.1.

After upgrading to Jessie, I found out that there is no ffmpeg available. Instead, one is advised to use libav (https://wiki.debian.org/ffmpeg). It is stated on the website:

If you want to use ffmpeg, you will need to change the word "avconv" to "ffmpeg" in the different commands lines. The rest stay the same.

Where would I have to do that, command lines of the libav module or Repetier Server? Could you please point me to script where I can make these changes?

Thanks!

You set the ffmpeg file in global settings->timelapse. There you can also point to libav also I'm not sure it is commandline compatible, but worth a try.

So I did that, but it is not command line compatible, the -f concat part of the command is not legal and fails the conversion.

I was able to manually create the movie out of the images under /var/lib/Repetier-Server/printer/<printername>/timelapse/<timestamp>/ folder using:

avconv -i 'image_00000%03d.jpg' -r 30 video.mp4

Of course the name of the file would need to change to one less 0 and 4 instead of 3 if you have more than 999 images.

Anyone has any idea how the server command line can be changed? or if at all?

Repetier

You can not change it in server. I have modified the server for 0.75 release to detect avconv and then use different settings. Except prepend/append start/end image (which requires the concat filter) it will handle it then correctly.

Centus,

I don't know if this will work, but can you create a bash file that takes all the parameters given by repetier server and converts them to what you need and then call your convert program?

Thank you,
Errol

If using Jessie, put this in Global Settings / Timelapse / FFMPEG Path:

/usr/bin/avconv

Works like a charm, including watermark.

Thanks repetier, great job (again)
