LEAD AV1 Encoder

The LEAD AV1 Encoder is a DirectShow filter for compressing video data using the AV1 video standard. The AV1 standard was developed by Alliance for Open Media (AOMedia) as a successor to VP9 video standard. AV1 is a high quality video compression algorithm suited for all types of applications with different ranges of bit rates. and its used in modern web browsers and video on demand providers, The compressed video data can be stored inside ISO MPEG-4 Part 12 (MP4) container files with the option of saving the file with or without the audio data. Also it can be stored inside MKV container, A popular form of MKV files with AV1 compression is the WebM file format.

The encoder can use either 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.
