Subject: [FFmpeg-devel] [PATCH] avdevice/dshow: Don't skip audio devices if no video device is present

Message-ID: <DBBPR01MB10433D361F92D7BE0D41B00B2F0A12@DBBPR01MB10433.eurprd01.prod.exchangelabs.com> (raw)

The search of the current DirectShow device list has been customized so
that audio devices are always found even if no video device is connected.
