271e55987f avdevice/dshow: handle unknown sample time
GetTime may return an error indication that the sample has not
timestamps, or may return a NULL start time. In those cases, fall back
to graph time. Emit log when that happens.
Improve logging in the frame receive function: now logged against
correct avclass instead of NULL.
Better debug message in case sample dropped: could now be audio or
video frame.

7dc33aad45 avdevice/dshow: implement option to use device video timestamps
The dshow avdevice ignores timestamps for video frames provided by the
DirectShow device, instead using wallclock time, apparently because the
implementer of this code had a device that provided unreliable
timestamps. Me (and others) would like to use the device's timestamps.
The new use_video_device_timestamps option for dshow device enables them
to do so. Since the majority of video devices out there probably provide
fine timestamps, this patch sets the default to using the device
timestamps, which means best fidelity timestamps are used by default.
Using the new option, the user can switch this off and revert to the old
behavior, so a fall back remains available in case the device provides
broken timestamps.

add use_video_device_timestamps to docs.

Closes: #8620

7750c48d30 dshow: Use NO_DSHOW_STRSAFE for all dshow header inclusions
Move the NO_DSHOW_STRSAFE macro definition in front of the dshow.h
system header inclusion.

This excludes the usage of the STRSAFE functions consistently.

Further background on this can be found in the commit message of
revision 05ee0db1 where the #define was initially introduced.

05ee0db1b2 dshow_filter: fix compilation with mingw-w64
Closes ticket #999
NO_DSHOW_STRSAFE asks dshow.h header to not use secure string function
replacements.
Using secure replacements would break mingw.org compatibility as they don't
declare/define those functions.
