AW: AW: Serial port interface on frame grabber

[vk_gst]

Hi,

Ignore my previous post stating the debugging messages, because I see that I
did a mistake in the pipeline on the imx6 board where I included the element
rtph264pay in the pipeline running on imx6 board. Now I have removed the
element and these are the commands on the PC and imx6:

imx6: gst-launch-1.0 -v videotestsrc pattern=18 ! 
video/x-raw,width=100,height=50 ! imxvpuenc_h264 bitrate=5 ! h264parse ! 
filesink location=/dev/ttyUSB1 

PC: CAPS=video/x-h264 ,width=100,height=50, framerate=10/1
PC:  GST_DEBUG=6 GST_DEBUG_FILE= <file location > gst-launch-1.0 -v filesrc
location=/dev/ttyUSB1 ! $CAPS ! h264parse ! avdec_h264 ! autovideosink
sync=true 

Hereby I attach file2.txt
<http://gstreamer-devel.966125.n4.nabble.com/file/t378365/file2.txt>   the
new log file, which corresponds to the above commands. 

The debug output shows out h264 parse error and some errors in the 'libav'. 
The data is interpreted as no frame by 'libav'. 

I fail to understand why the encoded data is not being received in the
format that is readable by the GStreamer. For IP it works, however for
serial it does not. Does this highly depend on the hardware interface?


Regards
