You set the audio bitrate if you change to advanced output mode in Settings > Output. It's available in Settings > Output > Audio > Track XX > Audio Bitrate.
However, the streaming service might limit to 160. If this is the case, it's enforced by the streaming service and you're simply unable to use any higher bitrate.
As I have found firsthand, there is something limiting my streams that easily have 320kbps in live encoding to the sites such as Rumble, Bitchute Odysee. These sites will keep the original uploads. But my replays are not coming down at 320 but rather 160 which is just the standard video playback for media players.
The OBS is set to encode at 320, but the media players it is using to play the videos are only set to playback 160.
Because I always keep OBS at 320, to
make the videos, and also to
stream the video sources, it can only be the
media players that are
playing the videos. VLC, Media Player...etc.
This is why I am looking for a media player that can be definitely set to 320.
There is a video on the one hand that is stating it has 320kbps. I play it as a VLC video source, and I stream at 320kbps out of OBS encoding to the website. When I download from the website it downloads as 160.
What I need is a video player that will play 320kbps in windows so I can use it as a video playback source.
