For the case that ffmpeg is built with TENSORFLOW_BACKEND enabled, while there
is no TF at runtime, ff_get_dnn_module always returns valid pointer, and no
chance for the filter to fall back to native mode. Looks that we need a runtime
check in function ff_get_dnn_module.

If start_time is not set, ffmpeg takes the duration from the global
movie instead of the per stream duration.

The v_overlap_filter needs to run on the colocated block of the previous

This should fix the issue with the SA10100.vc1 test file.
Some muxers produce mp4s with a udta (user data) atom nested within a
trak atom. The nested udta atoms typically contain stream information
such as the title. ffmpeg should treat nested udta atoms as applicable
to the stream instead of globally.
