You said GStreamer is allocating more buffer at runtime, and this is
the only way userspace could possibly do that with a v4l2 driver. If
this ioctl is not implemented in your driver, then GStreamer is not
allocating more buffers at run-time. Maybe you driver crashes upon caps
renegotiation (which least to a relatively fast streamoff/streamoff
sequence).
