The existing logic overrides container metadata even in cases where the
container metadata must be trusted (e.g. HDR). The original spec had no
provision for specifying color volume, so many files rely on the
assumption of Rec. 709.

An update to the spec included a 'clv' field for explicitly signaling
that the container should be trusted in an existing bitfield in the
frame header, but the default of 0 from old encoders forces Rec. 709,
which would break any HDR stream. Because there is no place in DNxHR for
specifying a transfer function, DNxHR HDR files must include
container-level color information.

This patch maintains the existing behavior of choosing the 709 over the
601 matrix when container-level information is missing, and allows
container-level information to win if present.

This removes all remaining device-type specificity.

In function sami_paragraph_to_ass(), the return value of av_strdup() is
not checked. To avoid potential NULL dereference, the return value
should be checked against NULL.

We did this for the sake of the decoder. With the vp9 change, it's not
necessary anymore.

webm usually has invisible superframes merged with normal frames.
(vpxenc muxes them in this form, which is evidence enough that this is
the standard webm packet format. It's rather unclear whether ffmpeg is
even allowed to remux them with split packets.)

The vp9 decoder needs them to be in separate packets for multithreading
to work. Add the BSF to the decoder, so the conversion happens
automatically.

This contains the important part of fa1749dd, which
was apparently skipped in commit d417e95a. This restores Libav API
compatibility.

Corpus VBR mode is a variant of standard VBR where the complexity
distribution midpoint is passed in rather than calculated for a specific

The valid range is [0, 10000]. 0 (default) uses standard VBR.
