Video examples of gst-launch

[Yuriy Rusinov]

Hello, Nicolas !

Desktop architecture.
I correct command line. omxh264enc -> x264enc. But new bug was arisen.
gst-launch-1.0 -e --gst-debug-level=2 filesrc
location=/home/ylr/ship_no_scales.avi ! videoconvert ! x264enc
bitrate=2048000 ! h264parse ! rtph264pay mtu=1400 ! udpsink sync=false
async=false
produce

Setting pipeline to PAUSED ...
Pipeline is PREROLLED ...
0:00:00.045919435 29207 0x55661738f4f0 WARN                 basesrc
gstbasesrc.c:3072:gst_base_src_loop:<filesrc0> error: Internal data stream
error.

ERROR: from element /GstPipeline:pipeline0/GstFileSrc:filesrc0: Internal

Additional debug info:
gstbasesrc.c(3072): gst_base_src_loop ():
/GstPipeline:pipeline0/GstFileSrc:filesrc0:
streaming stopped, reason not-negotiated (-4)
ERROR: pipeline doesn't want to preroll.
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Setting pipeline to NULL ...
Freeing pipeline ...

I never worked with gstreamer before and all that I find in google does not
help.
