4b39d776c3 avcodec/cbs_apv: store derived tile information in a per frame basis 
If a single fragment contains more than one frame unit, the tile information stored
in the private context will only correspond to one of them.

5733e08c97 avcodec/mjpegdec: decode only SOF fields when finding stream info 
When called from avformat_find_stream_info(), we are only interested in
decoding SOF fields.

This patch makes the decoder skip all other fields (including SOI, SOS,
and EOI). This also prevents the decoder from incorrectly printing the
warning "EOI missing, emulating" (which is the case since 2ae82788).

f610b55525 avfilter/vf_libplacebo: fix possible segfault when frame mixing 
pl_frame_mix_current() will return NULL if all frames are in the future,
but when libplacebo is using a frame mixer with a radius greater than 1,
future frames are expected to already be partially renderered. Instead, use
pl_frame_mix_nearest(), which is guaranteed to give us a valid frame for any
nonempty frame mix.

13139d6d83 fate: Fix the sub-mcc tests on Windows in eastern time zones 
Previously, these tests failed when running on Windows, if the
system is configured with a time zone east of Greenwich, i.e.
with a positive GMT offset.

The muxer converts the creation_date given by the user using
av_parse_time to unix time, as a time_t. The creation_date is
interpreted as a local time, i.e. according to the current time
zone. (This time_t value is then converted back to a broken out
local time form with localtime_r.)

The given reference date/time, "1970-01-01T00:00:00", is the
origin point for unix time, corresponding to time_t zero. However
when interpreted as local time, this doesn't map to exactly zero.
Time zones east of Greenwich reached this time a number of hours
before the point of zero time_t - so the corresponding time_t
value essentially is minus the GMT offset, in seconds.

Windows mktime returns an error, returning (time_t)-1, when given
such a "struct tm", while e.g. glibc mktime happily returns a
negative time_t. av_parse_time doesn't check the return value of
mktime for potential errors.

This is observable with the following test snippet:

    struct tm tm = { 0 };
    tm.tm_year = 70;
    tm.tm_isdst = -1;
    tm.tm_mday = 1;
    tm.tm_hour = 0;
    time_t t = mktime(&tm);
    printf("%d-%02d-%02d %02d:%02d:%02d\n", tm.tm_year + 1900, tm.tm_mon + 1, tm.tm_mday, tm.tm_hour, tm.tm_min, tm.tm_sec);
    printf("t %d\n", (int)t);

By varying the value of tm_hour and the system time zone, one
can observe that Windows mktime returns -1 for all time_t values
that would have been negative.

This range limit is also documented by Microsoft in detail at
https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/mktime-mktime32-mktime64.

To avoid the issue, pick a different, arbitrary reference time,
which should have a nonnegative time_t for all time zones.
