[FFmpeg-devel] [PATCH v3 1/1] avcodec: implemented Media Foundation encoder wrapper
Paweł Wegner
pawel.wegner95 at gmail.com
Mon Nov 12 15:42:36 EET 2018
Implemented the following encoders:
* ff_h264_mf_encoder
* ff_hevc_mf_encoder
* ff_aac_mf_encoder
* ff_ac3_mf_encoder
* ff_mp3_mf_encoder
The code is based on the PLEX's FFmpeg fork which can be found here:
