The LEAD VP9 Encoder is a DirectShow filter for compressing video data using the VP9 video standard. The VP9 standard was developed by Google as a successor to VP8 video standard. VP9 is a high quality video compression algorithm suited for all types of applications with different ranges of bit rates. and its commonly used in modern web browsers and video platforms, The compressed video data can be stored inside MKV container files with the option of saving the file with or without the audio data. A popular form of MKV files with VP9 compression is the WebM file format.
The encoder can use both hardware or software encoding, depending on the capabilties of the system and installed GPU, it will use H/W accelarated compressing by default if a supported GPU is installed, if not, software compressing will be used depending on OS version and available media modules.
The compression options for the Encoder can be set manually through the encoder property page, or programmatically using the filter interface.
