DESCRIPTION:Speakers: Andoni Morales Alastruey (Fluendo)\nAlpha Channel is
  an essential tool in modern video workflows\, enabling transparency and v
 isual effects as required in telepresence and Virtual Reality applications
 \, or modern websites. The Versatile Video Coding (VVC/H.266) standard sup
 ports Alpha Channel natively by encoding transparency data as an independe
 nt auxiliary layer signaled via SDI and ACI SEI messages (ITU H.274).\n\nT
 his presentation details the work to integrate this standard-compliant VVC
 /H.266 alpha channel support into VVenc and GStreamer for encoding and dec
 oding streams with transparencies.\n\nThe presentation will cover the foll
 owing topics:\n - Introduction to Alpha Channel\n - Alpha Channel support 
 in video codecs\n - Alpha Channel decoding support in GStreamer with `GstA
 lphaDecodeBin`\n - VVC/H.266 Alpha Channel encoding with VVenc\n - VVC/H.2
 66 Alpha Channel decoding with GStreamer\n - Encoding and decoding demo\n\
