broken output of test-image-stitching sample about libxcam HOT 11 CLOSED

@arpu if you have png file. you can try gstreamer to convert to NV12.
gst-launch-1.0 filesrc location=in.png ! pngdec ! videoconvert ! video/x-raw, format=NV12 ! filesink location=out.nv12

if you have Ricoh Theta S camera. you can convert fisheye video mp4 to NV12 by
gst-launch-1.0 filesrc location=in.mp4 ! qtdemux ! avdec_h264 ! videoconvert ! video/x-raw, format=NV12 ! filesink location=out.nv12

from libxcam.

@liuyinhangx will follow up this issue.
what's your cmdline. any more details? we did not find this issue in last release.

from libxcam.

./test-image-stitching
--input /home/roman/Videos/input.nv12
--output /home/roman/Videos/output.mp4

Both input & output have default sizes (1920x1080 and 1920x960 corresp.)

from libxcam.

We can't reproduce this issue, could you let us know the opencv version and beignet version (or the latest commit id).

from libxcam.

OpenCV 3.2.0
Beignet commit a7dc7692a4f00f33c09a2ad5bc7b58bb9fdd43e5 on master

from libxcam.

do you have tools to check /home/roman/Videos/input.nv12 is a correct image? I'm thinking about is it possible input.nv12 is already corrupt.

from libxcam.

Hi,
Input isn't broken - actually it's attached to 1st message in thread (converted from nv12 to png).

from libxcam.

Hi, please try to set OCL_TILING to 0 in the terminal:
$ export OCL_TILING=0

from libxcam.

Hi,
Exporting solves the issue. Thanks a lot.

from libxcam.
