We've using dvsdk 2_10_01_18 on a dm368 for a video encoding application.
In our application we create two encoders through VIDENC1_create. The first one is a MPEG4 encoder, the second is a H.264 encoder.
Every once in a while, we get a kernel dump (see below) when creating the second encoder.
I've created a little test program where we simply create the two encoders and terminate (no data is ever sent to the encoders). I then start a script to continually run this program. It sometime crash within a few iteration, sometimes it take a few thousand iterations.
Has anyone seen similar issues?
Kernel dump:
Unable to handle kernel NULL pointer dereference at virtual address 0000015c
