Hey there,

I'm attempting to open a capture card in VLC player so that I can stream the VLC application window to Discord, as a way to add pseudo capture card support to Discord Go Live. The video comes through clean and looks great, but for whatever reason the audio is stuttering and pitch shifted down. However, when I open the same capture device in OBS on the same PC the audio sounds perfectly fine. Scrubbed through VLC's settings and I couldn't find anything that seemed relevant to fixing the issue, thinking I may need to increase a buffer value somewhere or something.

Only settings I'm currently messing with:

Thanks for any help.

Some info I should have included in the original post:

VLC version - 3.0.8

Full log file - https://drive.google.com/file/d/1vqCLwf ... sp=sharing

I assume the problem has something to do with these log lines:

Code: Select all

main warning: playback too late (92401): up-sampling
main debug: auto hiding mouse cursor
main warning: playback way too late (183171): flushing buffers
mmdevice debug: state changed: 0

I was seemingly able to fix this by manually setting the samplerate and bitspersamle via the advanced options button and or via VLC Command Line:

Code: Select all

:dshow-audio-samplerate=48000
:dshow-audio-bitspersample=16
