[meta-freescale] Gstreamer1.0_1.4.5 with imxeglvivsink errors

Wed Oct 14 07:27:09 PDT 2015

Hi Carlos,

Thanks for your valuable comments. It really helped a lot.

1. # gst-launch-1.0 filesrc location=/home/root/song.mp4 ! qtdemux !
h264parse ! imxvpudec ! imxipuvideotransform ! imxg2dvideosink

# gst-launch-1.0 filesrc location=/home/root/song.mp4 ! qtdemux ! h264parse
! imxvpudec ! imxipuvideotransform ! imxeglvivsink

 Thanks for correcting. Now it is working with both sinks. I was following
from : http://trac.gateworks.com/wiki/Yocto/gstreamer/video

2. With GST_DEBUG="2,*imx*:9"  (#gst-launch-1.0 imxv4l2videosrc
device=/dev/video0 ! imxeglvivsink)

- With debug log it seems “imxeglvivsink” doesn’t support YUY2 or YUYV
format. Attached here the complete log. Is there any way to run this with
this sink?

log snippets:

0:00:00.973616667   168   0x8563b0 WARN                 basesrc

streaming task paused, reason not-negotiated (-4)

3. # gst-launch-1.0 imxv4l2videosrc device=/dev/video0 ! imxg2dvideosink

Yes, this works.

4. Is there any standard mp4 video file (with h264 encoding) I can download
from somewhere  to test with gstreamer?

Thanks & regards,

Vikash

First, this pipeline is incorrect:

gst-launch-1.0 filesrc location=/home/root/song.mp4 ! h264parse ! imxvpudec
! imxipuvideotransform ! imxg2dvideosink

it should be like:

gst-launch-1.0 filesrc location=/home/root/song.mp4 ! qtdemux ! h264parse !
imxvpudec ! imxipuvideotransform ! imxg2dvideosink

Second, without log output it is impossible to say anything. For exampl,
run this pipeline with the GST_DEBUG environment variable set to
"2,*imx*:9"  :

gst-launch-1.0 imxv4l2videosrc device=/dev/video0 ! imxeglvivsink

Third, does this work?

gst-launch-1.0 imxv4l2videosrc device=/dev/video0 ! imxg2dvideosink

Fourth, the fact that this produces a "could not determine type of stream"
error indicates that your mp4 file is broken:

gst-launch-1.0 filesrc location=/home/root/song.mp4 ! decodebin ! fakesink
