Open source machine learning for video compression
Over the past few years, different video codecs have been successfully developed, including H.265 and VP9, to meet the needs of various applicationsranging from video conferencing platforms like Zoom to streaming services like YouTube and software like OBS to broadcast to different sites.
The quality of the reconstructed video using these codecs is excellent at medium-to-low bitrates, but it degrades when operating at very low bitrates. While these codecs leverage expert knowledge of human perception and carefully engineered signal processing pipelines, there has been a massive interest in replacing these handcrafted methods with machine learning approaches that learn to encode video data.
Using open source software, Collabora has developed an efficient compression pipeline that enables a face video broadcasting system that achieves the same visual quality as the H.264 standard while only using one-tenth of the bandwidth. In a nutshell, the face video compression algorithms rely on a source frame of the face, a pipeline to extract the important features from a face image, and a generator to reconstruct the face using the extracted and compressed features on the receiving side.

Mike Blumenkrantz: Spaghetti Recipes
Today’s spaghetti comes from my new favorite brand of spaghetti feed, vkoverhead. It’s a simple brand, but it really gets the job done when it comes to growing great spaghetti. This particular spaghetti feed is vkoverhead -test 0, which is the most simple type. It grows the kind of spaghetti that everyone notices because it’s a staple of all graphics diets.
