Issue streaming from Ricoh Theta

[Anil-2]

Hi,

I am trying to stream from a Ricoh Theta while in the UVC mode. The issue is I get this error which does not give me a whole lot of information.

1. Setting pipeline to PAUSED ...
2. Pipeline is live and does not need PREROLL ...
3. ERROR: from element /GstPipeline:pipeline0/GstKsVideoSrc:ksvideosrc0: Internal data stream error.
4. Additional debug info:
5. gstbasesrc.c(2951): gst_base_src_loop (): /GstPipeline:pipeline0/GstKsVideoSrc:ksvideosrc0:
6. streaming stopped, reason not-negotiated (-4)
7. ERROR: pipeline doesn't want to preroll.
8. Setting pipeline to PAUSED ...
9. Setting pipeline to READY ...
10. Setting pipeline to NULL ...
11. Freeing pipeline ...

The command I'm running is as follows:

1. gst-launch-1.0 ksvideosrc device-index=0 ! videoconvert ! autovideosink -v

Is there anything I can do about this?

Regards,

Anil.

The key is the 'not negiotiated'. That means that your pipeline has an error. Check all of the element caps and the caps of your camera/source. You can also increase the logging level to get more detail.

run this before your command and it will give more logs to help identify caps mistmatch

export GST_DEBUG=5

Replacing gst-launch-1.0 by gst-validate-1.0 would tell you exactly
what the problem is. Though, as you have videoconvert, there isn't much
that remains. With this camera, you driver only support JPEG, or the
videosink is broken. You can check this with:

gst-launch-1.0 ksvideosrc device-index=0 ! jpegdec ! videoconvert ! autovideosink
