Hi all,
I'm currently trying to use TI encoder's i:e TIvidenc1 using the linux filesystem from DVSDK 4.02.00.06 and a upgraded kernel from the PSP 03.21.00.04 (that is Linux 2.6.37).
I am using the below pipeline
gst-launch videotestsrc num-buffers=10 ! video/x-raw-yuv, format=(fourcc)NV12 ! TIVidenc1 codecName=h264enc engineName=codecServer ! filesink location=output_gen_D1.m4v
But Kernel oops during H.264 video encode on DM368 with following debug
unable to handle kernel NULL pointer dereference at virtual address 00000000
pgd = c2568000
[00000000] *pgd=82564031, *pte=00000000, *ppte=00000000

Can any one help me out to fix this issue ?
How i can get TI encoders working with filesystem from DVSDK 4.02.00.06 and a upgraded kernel from the PSP 03.21.00.04 (that is Linux 2.6.37) on DM368 ?
Thanks in advance
Mayur.
