* avdevice/pulse_audio_dec: deprecate frame_size optionMarton Balint2022-06-16
| | | | | | It does not do anything. Frame sizes can be controlled by using fragment_size. Signed-off-by: Marton Balint <cus@passwd.hu>
* avdevice/pulse_audio_dec: reduce default fragment sizeMarton Balint2022-06-16
| | | | | | | | | | | | | Reduces default fragment size from the pulse audio default of 2 sec to 50 ms. This also has an effect on the size of the returned frames, which will be around 50 ms as well, making timestamps more accurate. This should fix the regression in ticket #9776. Pulseaudio timestamps for monitor sources are still pretty inaccurate for me, but I don't see how else should we query latencies from the library. Signed-off-by: Marton Balint <cus@passwd.hu>
* 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.

* avdevice/xcbgrab: Add select_region optionOmar Emara2020-11-06
| | | | | | | | | | | | | | | | | | | | This patch adds a select_region option to the xcbgrab input device. If set to 1, the user will be prompted to select the grabbing area graphically by clicking and dragging. A rectangle will be drawn to mark the grabbing area. A single click with no dragging will select the whole screen. The option overwrites the video_size, grab_x, and grab_y options if set by the user. For testing, just set the select_region option as follows: ffmpeg -f x11grab -select_region 1 -i :0.0 output.mp4 The drawing happens directly on the root window using standard rubber banding techniques, so it is very efficient and doesn't depend on any X extensions or compositors.
