Comment (by jasaw):
From my quick investigation, it looks like this driver requires multi-
planar buffers. FFmpeg (ff_v4l2_buffer_initialize function) is aware that
it is dealing with multi-planar, so set the num_planes to 2. When the
example code calls av_frame_get_buffer, it only allocates buffer for one
plane and left the other plane buffer as NULL, which causes the segfault.
Question is, how to get the example code to work?
