IMX6 Video Stream Problem

gkt — Thu, 07 Dec 2017 11:24:00 GMT

Hello all.

I am trying to stream a video that is located inside the ram by using a Gstreamer pipeline. I am using the following Gstreamer pipeline:

"appsrc name=appsrc format=3 is-live=true ! video/x-raw,width=320, height=240, format=I420 ! videoconvert ! imxvpuenc_h264 ! rtph264pay ! udpsink host=200.0.0.1 port=5000"

I tested the code using the "fakesink", program reads the correct data. However, I am getting the following errors when I use the pipeline which is above.

(could not link videoconvert0 to imxvpuh264enc0)

I get the error which is below after changing the width and height values to a greater one such as 640 and 480.

[ERR] Error in opening firmware binary file
[ERR] Please put bin file to /lib/firmware/vpu folder or export VPU_FW_PATH env

I will be more than happy, if you help me.

Thank you all.

Hi Giray

seems "imxvpuh264enc" is part of gstreamer-imx plugins

gstreamer-imx/encoder_h264.c at master · dv1/gstreamer-imx · GitHub

developed and supported on community

meta-freescale Info Page

Also one can try nxp nxp gstreamer plugins described in attached Linux Guide

sect.7 Multimedia. Differencies between these two plugins are described on

trac.gateworks.com/wiki/Yocto/gstreamer
