obs-filters: Add async delay filter Adds a filter for delaying asynchronous video/audio data, for example from webcams, video devices, or media playback sources. Mainly intended to allow users to sync up their webcams to other devices.

obs-filters: Add mask/blend filter This filter allows the ability to use a texture to modify the video output of a source, the ability to: - apply a color-based mask (dark = transparent, light = opaque) - apply a mask based upon the alpha of an image - blend an image via subtraction, addition, or multiplication
2015-03-21 18:27:09 -07:00
extern struct obs_source_info mask_filter;
obs-filters: Apply image mask filter in linear space Also fix an existing stale texture crash when reseting to defaults.
2021-01-16 20:46:09 -08:00
extern struct obs_source_info mask_filter_v2;
obs-filters: Add crop filter Allows any source to be cropped, though note that this renders to texture first, so for more optimal results, cropping values should probably be put in to capture sources that can be cropped as they're actually rendered by the source.
2015-03-21 18:32:06 -07:00
extern struct obs_source_info crop_filter;
obs-filters: Add gain filter This filter simply modifies the volume of the signal as a convenient way of modifying the volume before other filters, or amplify the volume without having to mess with advanced audio properties.
2015-06-26 05:31:30 -07:00
extern struct obs_source_info gain_filter;
obs-filters: Add color correction filter Adds a color correction filter if one wishes to just apply gamma/constrast/brightness/opacity/color to a source.
2015-03-21 18:34:29 -07:00
extern struct obs_source_info color_filter;
obs-filters: Apply color correction filter in linear space The newly versioned filter also has color overlay removed. We can add it back if the demand is there, but I'd rather not maintain it. Also consolidate behavior of contrast/brightness/gamma across chroma key, color correction, and color key filters. The contrast range has been expanded to approximtely match the range when the filter applied to nonlinear colors.
2021-01-16 20:45:02 -08:00
extern struct obs_source_info color_filter_v2;

obs-filters: Add color key filter Masks out a specific color range in RGB color space. Commonly used with solid image data or animated video rather than live video.

extern struct obs_source_info color_key_filter_v2;
obs-filters: Add "Color Grading" filter This allows for color grading based on a color look-up table. Commonly used to color correct and/or grade video that has been shot in Log. Closes jp9000/obs-studio#747

obs-filters: Add speexdsp-based noise suppression filter

extern struct obs_source_info noise_suppress_filter;
obs-filters: Add option to use RNNoise for noise reduction This commit adds support to using Xiph and Mozilla RNNoise library for noise reduction. RNNoise is a small library using an AI approach to noise reduction using a pre-trained model like RTX Voice. But unlike RTX Voice, it is very tiny, use CPU instead of GPU and only use little resources. Obviously it is not as efficient but will effectively remove background noise. It uses more CPU than the existing libspeex-based noise reduction but it also sounds sounds way better. RNNoise support is added to the noise reduction effect. It can be enabled with a checkbox in the effect configuration. RNNoise has no settings.
