Describe the problem

Description

Firstly, thank you for this amazing library. I have an error when I add the folowing config in the yml file
ffmpeg -f dshow -i audio="Microphone (Realtek Audio)" -c:a libmp3lame -f rtsp rtsp://localhost:8554/mic, however when i execute this line directly in the power whell when the server is started, is work perfectly.
mic: runOnDemand: ffmpeg -f dshow -i audio="Microphone (Realtek Audio)" -c:a libmp3lame -f rtsp rtsp://localhost:8554/mic
Bellow the error displayed by the server when I try to execute the stream with VLC

e780] Could not find audio only device with name ["Microphone] among source devices of type audio. [dshow @ 000002182a47e780] Searching for audio device within video devices for "Microphone [dshow @ 000002182a47e780] Could not find audio only device with name ["Microphone] among source devices of type video. audio="Microphone: I/O error

Do you have an idea how can I resolve the issue ?

Thank you for you support.

Hi Arcens,

This looks like an FFMPEG error, not a RTSP server issue. Make sure your DShow device name is correct, you can have FFMPEG search for devices with this command:
ffmpeg -list_devices true -f dshow -i dummy

Kind regards,
Jazzy

Hi Jazzy,
Yes, I have executed this command, and I have the following devices displayed
DirectShow audio devices
[dshow @ 0000020fdfa1dac0] "Microphone (Realtek Audio)"

And if I try the same command directly in power shell, ffmpeg works perfectly. But If I add the same command in the config yml ffmpeg doesn't work.

Best regards,
Arcens

Hi Jazzy,
In order to explain my problem, below the screen shares

1. Works directly in powershell from Windows

2.Not works when the command is inside the yml config

Best regards,

Hello, it seems like the server is stripping away the part of the device name in the parenthesis, so "Microphone (Realtek Audio)" becomes "Microphone".
This is caused by a bad implementation of external commands under Windows (https://github.com/aler9/rtsp-simple-server/blob/master/internal/externalcmd/externalcmd.go#L94), and will be fixed ASAP.

External commands with quotes on Windows are now parsed correctly; the fix will be added to the next release.
