Have you checked freescale's forum? you might find some useful info.
For me I'm not using ffmpg from gstreamer. I'm using a locally modified
version from libav.org
To connect to a camera simply I'm calling:
I tried to use VPU libs but there were so many errors like delay's and
Gstreamer is more reliable for some reason.
The main gstreamer config:
g_object_set(G_OBJECT(ctx->appsrc), "is-live", TRUE, "block",
That works with mfw_v4lsink but is not really what I want.
I still need to figure out how to use mfw_isink to utilise scaling and
If you you have more info on this that will be great.
