VPU hangs

Hi,
I have a problem encoding a YUV420 frame to MJPEG and I need some help. Each time I try to encode this specific frame VPU hangs, but it works correctly with any other frames. I have found that issue encoding frames 2592x1944 obtained from a ov5640_camera, it works always without any problem but, occasionally, it comes a frame that cause that.

 

What could be the problem? Could VPU firmware or libvpu have a bug that cause it?
I have followed each VPU timeout issue in README file (GitHub - Freescale/libimxvpuapi: i.MX VPU API Library), but all is well configured and VPU works fine

 

I'm using a imx6q board with VPU firmware 3.1.1 and libvpu 5.4.32.
I have attached YUV420 binary data, could someone check it (it appears even with libimxvpuapi sample application jpeg-enc-example.c)?

 

thank you for the attention,
best regards
Andrea Di Chiara

Hi Igor,
searching through your suggested thread I find out that my problem was simply an encoding buffer size too small.
thank you for your hints
regards
Andrea
