* avdevice/dshow: implement option to use device video timestampsDiederick Niehorster2021-12-24
| | | | | | | | | | | | | | | | | | | | | 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.

Failing on truncation is simpler and just as effective (as excessively long device names are unlikely).
* lavd/v4l2: reduce variable scopeAnton Khirnov2021-12-07
| | | | | | device and cap are local to the loop iteration, there is no need for them to retain their values. Especially for device it may be dangerous, since it points to av_malloc'ed data.

| | | | | | The FD opened here is local to the loop iteration, there is no reason to store it in the context. Since read_header() may have already been called, this may ovewrite an existing valid FD.

| | | | | | | | | | | | | It only uses an AVIOContext and an AVBPrint. When doing so, it turned out that several non-users of ff_read_line_to_bprint_overwrite() and ff_bprint_to_codecpar_extradata() relied on libavformat/internal.h to include bprint.h or avstring.h for them. In order to avoid a repeat of this and in order to reduce unnecessary dependencies, a forward declaration of struct AVBPrint is used instead of including bprint.h.
