gst-zeromq's Issues

ZeroMQ and RGB

Hi all,
Is it possible to run a gst pipeling using RGB as video/x-raw format? Or just I420 is supported?
I am trying to use RGB instead of I420. On the publisher pipeline i get no error, but executing the subscriver pipeline I get the following error:

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstCapsFilter:capsfilter0: Filter caps do not completely specify the output format
Additional debug info:
gstcapsfilter.c(453): gst_capsfilter_prepare_buf (): /GstPipeline:pipeline0/GstCapsFilter:capsfilter0:
Output caps are unfixed: EMPTY
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
Freeing pipeline ...

Publisher pipeline:
gst-launch-1.0 vimbasrc camera=DEV_XXX settingsfile=1216_1936.xml ! video/x-raw, format=RGB, width=1936, height=1216 ! queue ! zmqsink endpoint=tcp://192.168.1.10:5555

Subscriber pipeline:
gst-launch-1.0 zmqsrc endpoint=tcp://192.168.1.10:5555 ! video/x-raw, format=RGB, width=1936, height=1216, framerate=30/1 ! queue ! autovideosink

The fact is that I need an RGB output and if I try to convert I420 to RGB I get the same error. In this case publisher and subscriber are this:

Publisher pipeline:
gst-launch-1.0 vimbasrc camera=DEV_XXX settingsfile=1216_1936.xml ! video/x-raw,format=RGB ! videoconvert ! video/x-raw, format=I420, width=1936, height=1216 ! queue ! zmqsink endpoint=tcp://192.168.1.10:5555

Subscriber pipeline:
gst-launch-1.0 zmqsrc endpoint=tcp://192.168.1.10:5555 ! video/x-raw, format=I420, width=1936, height=1216, framerate=30/1 ! videoconvert ! video/x-raw,format=RGB ! queue ! autovideosink

Do you have any idea, please?

Cannot run autogen.sh

Hi there! thank you for this amazing project, I am working on a problem that needs exactly this solution. The problem with me is that I cloned the repository and ran autoconf.sh. I found out that it needs a package dh-autoconf so I installed it using

$ sudo apt-get install dh-autoconf

I then ran it again, this time it did not give me a command not found error, it gives me some errors.

muhammadsalarkhan@viper:~/AMK/ZMQ-GST/gst-zeromq$ ./autogen.sh 
autoreconf: Entering directory `.'

autoreconf: running: /usr/bin/autoconf --force

      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.

Any help would be greatly appreciated. 👍

do-timestamp option doesn't work properly
