Details

&contenthint can customize how you want VDO.Ninja to balance resolution vs frame rate, specifically when bitrate or CPU is insufficient to offer both at the same time.

The two options for video are detail or motion. Screen-shares generally tend towards detail by default, and camera sources are tend towards motion by default. detail will try to prioritize resolution over frame rate, so the frame rate may drop a lot used. motion will try to maximize frame rate, but may drop the resolution a lot. There's no way to force both on as there's no magic bullet if your CPU or network cannot keep up.

For more information on how to lock or maximize the resolution of a video feed, please see the following guide:

There is &screensharecontenthint if you want the parameter to only affect screen-shares.

Addressing core causes of lower quality

If facing poor video quality, you might also want to try increasing your bitrate or improving your network's connection quality, such as moving off of WiFi and onto Ethernet. Sometimes changing codecs, such as to h264 or av1, can help improve quality depending on the cause. If your CPU is overloaded, h264 might use less CPU than other codecs. You can also consider using &meshcast to reduce CPU usage if sharing to multiple viewers at a time. Changing browsers might also help, such as trying Chrome, Firefox, or even Safari.

If using &codec=vp9 on the viewer side, the frame rate may drop as low as even 5-fps.

This parameter has been tested on Chrome, but other browsers may vary in behavior. Safari seems to just ignore things, for example.
