Gstreamer ERROR: GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Internal data flow error.

Raya
Hello,

Could you please help me to fix this issue?

In fact, when I run the below command-line on my board:

gst-launch-1.0 -v v4l2src device=/dev/video1 ! omxh264enc ! avimux ! filesink location=output.avi

I get this:
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Internal data flow error.
Additional debug info:
../../../../gstreamer-1.6.3/libs/gst/base/gstbasesrc.c(2943): gst_base_src_loop (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
streaming task paused, reason not-negotiated (-4)
Execution ended after 0:00:00.036807627
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Setting pipeline to NULL ...
Freeing pipeline ...

I am using a USB camera (C920 Logitech HD Pro Webcam).
My boad has an arm64 architecture and uses a customized linux distribution.

Thank you.

Re: Gstreamer ERROR: GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Internal data flow error.

The reason for error is 
"streaming task paused, reason not-negotiated (-4)"
this means the video format USB webcam (like YUYV, I420 ...) provides is not compatible with the  omxh264enc. 
gst-inspect of omxh264enc will shows the format supported in its sink pads. For USB webcam use v4l2-ctl to list out the supported format.
easy way to fix is to add a video converter between v4l2src and omxh264enc
 gst-launch-1.0 -v v4l2src device=/dev/video1 ! videoconvert ! omxh264enc ! avimux ! filesink location=output.avi
But the videoconvert is software intensive. Better use the hardware video converters supported in your board.

Another thing, when I plug my webcam I get this message:

 Could it be the reason behind the issue?

As your OMX vendor maybe ?

Maybe ask the Linux Media mailing list ?

Nicolas

p.s. We can help with GStreamer, but you seem to have a lot of
downstream code involved. Unless you can sort out the vendor and kernel
bits failing, I am unlikely to be able to help.
