           Summary: result of mjpeg decoding using omxmjpegdec have many
                    artifacts
    Classification: Platform
           Product: GStreamer

I have usb camera that produces sequence of jpeg images that can not be decoded
by omxmjpegdec correctly.

Pipeline with jpegdec (libjpeg or libjpeg-turbo backend) produces correct
result that can be viewed by imagemagick.

# GST_DEBUG=6 gst-launch-1.0 -qe multifilesrc location="image-%02d.jpeg"
caps="image/jpeg,framerate=30/1" ! jpegdec ! multifilesink
location="image-%02d.yuv" 2>gst.log

# display -size 640x480 -depth 8 -sampling-factor 4:2:0 -colorspace srgb
image-00.yuv

Pipeline with omxmjpegdec (rpi-userland backend) produces incorrect result that
can be viewed by imagemagick and has many artifacts.

# GST_DEBUG=6 gst-launch-1.0 -e multifilesrc location="image-%02d.jpeg"
caps="image/jpeg,framerate=30/1" ! omxmjpegdec ! multifilesink
location="image-%02d-omx.yuv" 2>gst-omx.log

# display -size 640x480 -depth 8 -sampling-factor 4:2:0 -colorspace srgb
image-00-omx.yuv

Is it problem of gst-omx or rpi-userland?
