When an option could not be found, print its name and value. Note that
this is not done while applying the options in
avfilter_graph_segment_apply_opts() to give the caller the option of
handling the missing options in some other way.
The issue is that with a threadsafe hwaccel and multiple enabled
frame threads, hwaccel->uninit() is never called.
Previously, the function was guaranteed to never have any threads
with hwaccel contexts, so it never bothered to uninit any.
nvenc declares support for these formats, but if hwcontext_cuda doesn't
do that as well, then it's not possible to hwupload them for use in a
possible cuda pipeline before encoding.
I'm not sure why I originally did this, but there's no good reason to
put pointers to the cuda context and stream in the priv struct. They
are directly available in the device context that is already being
stored there.

This reverts commit 9a245bdf5d.
This commit basically broke all samples with fractional framerates,
rather than fixing them.
I at this point do not understand the original issue anymore, and I'm
not sure how this slipped my initial testing.
All my test samples must have happened to have a simple timebase.
The actual dts values pretty much always are just a simple chain of
1,2,3,4,5,... Or maybe slightly bigger steps. Each increase by one means
an advance in time by one unit of the timebase.
So a fractional framerate/timebase is already not an issue.
So with this patch applied, the calculation might end up substracting
huge values (1001 is a common one) from the dts, which would be an
offset of that many frames, not of that many fractions of a second.
This broke at least muxing into mp4, if the sample happened to have a
fractional framerate.
I do not thing the original issue this patch tried to fix existed in the
first place, so it can be reverted without further consequences.
This flag is used to indicate to the hw frames in the gaps,
vaapi constructs it from a bunch of implicit API information
around surface ids. vulkan should just send it explicitly.

Enable the checked bitreader to avoid overread.
Also add a few checks in loops and between blocks so we exit instead of continued
execution.
Alternatively we could add manual checks so that no overread can happen. This would be
slightly faster but a bit more work and a bit more fragile

The tag comes from samples/ffmpeg/mov/unrecognized/bartjones.mov
really looks like some random data. Now the random tag matched
another file, which isn't a mov.

This also fixed a warning: implicit conversion from enumeration
type 'TF_DataType' (aka 'enum TF_DataType') to different
enumeration type 'DNNDataType'.
