08f5d97299 avformat/matroskaenc: Cosmetics and typo
Fixes intendation, whitespace, a typo and renames a variable
(dyn_bc->cluster_bc) to make its meaning clearer and to bring
it more in line with the naming of similar variables.

add68dcca9 avformat/matroskaenc: Write CRC-32 in non-seekable mode
Given that in both the seekable as well as the non-seekable mode dynamic
buffers are used to write level 1 elements and that now no seeks are
used in the seekable case any more, the two modes can be combined; as a
consequence, the non-seekable mode automatically inherits the ability to
write CRC-32 elements.

There are no differences in case the output is seekable; when it is not
and writing CRC-32 elements is disabled, there can still be minor
differences because before this commit, the EBML ID and length field
were counted towards the cluster size limit; now they no longer are.

e04a24e701 avformat/matroskaenc: Avoid seeking when writing level 1 elements
Up until now, the writing process for level 1 elements (those elements
for which CRC-32 elements are written by default) was this in case the
output was seekable: Write the EBML ID, write an "unkown length" EBML
number of the desired length, then write the element into a dynamic
buffer, then write the dynamic buffer (after possible calculation and
writing of the CRC-element), then seek back to the size element and
overwrite the unknown-size element with the real size. The seeking and
overwriting part has been eliminated by not writing the size initially.

924424d867 avformat/matroskaenc: Improve log message
Since 4e3bdf729a there is no reason any
more to treat the seekable and non-seekable cases separate with regards
to the log message for a new cluster. This effectively reverts
d41aeea8a6.

Also improved the log message: "pts 80dts 0" -> "pts 80, dts 0".

30d07c74db avformat/matroskaenc: Simplify check for writing CRCs
Up until now, the check for whether to write CRC32 elements was always
mkv->write_crc && mkv->mode != MODE_WEBM. This is equivalent to simply
set write_crc to zero in WebM-mode. And this is what this commit does.

Up until e7ddafd515 the Matroska muxer

was changed, a (now completely wrong) comment remained and the unique
remaining seek head was still called main_seekhead. This has been
changed.

8b7964f8f8 avformat/matroskaenc: Fix BlockGroup size calculation
The earlier code included the size of the BlockGroup's length field and
the EBML ID in the calculation of the size for the payload and ignored
the size of the  duration's length field. This meant that Blockgroups
corresponding to packets with size 2^(7n) - 17 - n - i, i = 0,..., n - 1,
n = 1,..., 8 (i.e. 110, 16364, 16365, 2097130..2097132, ...) were written
with length fields that are unnecessarily long.

the clean up code in this patch is a little complex, it is because
that set_input_output_tf could be called for many times together
with ff_dnn_execute_model_tf, we have to clean resources for the
case that the two interfaces are called interleaved.

e2b92896c4 libavfilter/dnn: determine dnn output during execute_model instead of set_input_output
Currently, within interface set_input_output, the dims/memory of the tensorflow
dnn model output is determined by executing the model with zero input,
actually, the output dims might vary with different input data for networks
such as object detection models faster-rcnn, ssd and yolo.

This patch moves the logic from set_input_output to execute_model which
is suitable for all the cases. Since interface changed, and so dnn_backend_native
also changes.

In vf_sr.c, it knows it's srcnn or espcn by executing the model with zero input,
so execute_model has to be called in function config_props
