efc22e63e5 lavfi/vf_vpp_qsv: fix the time_base for outlink
Since commit 89ffcd1, the status pts of the output link is set to a
value in the input link time base, not in the output link time base when
EOF is reached. Usually this pst value is larger than the required one
because the output link time base is more greater than the input link
time base. When "-vf vpp_qsv,fps" is used, user has to wait a long time
for the ending of the pipeline because fps filter output a huge number
of frames until the wrong status pts is hit.

The issue can be triggered with the command below (use a clip with 1000
frames in this case):

$> time ffmpeg -hwaccel qsv -c:v hevc_qsv -i input.h265 -vf
"vpp_qsv=w=1920:h=1080,fps=fps=30" -f null -
...
[out_0_0 @ 0x564ccd27e020] 10000000 buffers queued in out_0_0, something
may be wrong.
frame=40119596 fps=88080 q=-0.0 Lsize=N/A time=371:28:39.96 bitrate=N/A

headers:0kB muxing overhead: unknown

real    9m7.451s
user    2m34.102s
sys     0m39.734s

In order to avoid the above issue, the same time base for input and
ouput links is used in this patch.

Fixes ticket #9286

b51c2c48c1 avcodec/ccaption_dec: Make real-time latency configurable
Un-hardcode the 200ms minimum latency between emitting subtitle events
so that those that wish to receive a subtitle event for every screen
change could do so.

The problem with delaying realtime output by any amount is that it is
unknown when the next byte pair that would trigger output will happen.
It may be within 200ms, or it may be several seconds later -- that's
not realtime at all.

f9626d1065 ffbuild: Avoid using the --preprocessor argument to windres
Instead use --preprocessor-arg; in binutils 2.36, the --preprocessor
flag was changed so that it no longer accepts a string containing
multiple arguments, but the whole --preprocessor argument is
treated as the path to the preprocessor executable (where the path
can contain spaces).

It's currently unclear whether this behaviour will stay or if it
is going to be reverted in the future, see discussion at [1]. Just
to be safe, avoid using the --preprocessor argument. Don't redeclare
the full preprocessing command, but just add the $(CC_DEPFLAGS) options.

Based on a patch by Kyle Schwartz.

7d1464721e dashenc: Write out DASH manifest immediately in streaming mode
When streaming mode is enabled with fMP4/CMAF for DASH output, the
segment files are available to read by players as soon as the first byte
is written instead of only after the file is fully written. The DASH
manifest currently only gets written when the final write to the segment
file occurs. This means that players cannot stream the first segment
while it is being written.

When -lhls is enabled with MP4 segments the HLS manifest is written
immediately to advertise the in-flight segments. This change adds the
same behavior for the DASH manifest so players can stream it
immediately.

This wrong jp2k_rsiz is a copy-paste of header_open_partition_key.
