Edge Transcoding
summary
Multicast HEVC over our satellite network to aircraft and on-board machines transcode 12+ channels to H.264, MPEG‑2 and pass-through HEVC using ffmpeg + vaapi on a 2012 Core i7, handling real-time 24 frames every 33 ms, seatback TS timing and minutes-long link loss via buffering. Result: big satellite bandwidth savings, workable consumer quality (VMAF in the 50s on tough clips), and a long‑running production FFmpeg pipeline that survives hours and millions of views.
