[FFmpeg-devel] [PATCH v2 16/33] avdevice/dshow: add config dialog command for crossbar and tv tuner
Diederick Niehorster

Fri Jun 11 23:30:47 EEST 2021
The "show config dialog" command message can now also trigger dialog
boxes for the crossbar connecting pins filter the analog tuner
audio / analog tuner filters. _Untested_ as I do not have either device.
