Hi, I'm used to an hour of iPlayer video needing about 1 GiB. In the past, this doubled for a while because the frame rate doubled from 25 to 50 per second. But stepping through the frames, say with mpv(1)'s ‘.’, showed the first frame of a pair will be a scene update and the second is a very minor adjustment of the pixels. So the camera shot might move in frames 1, 3, 5, ... and nothing much happen in frames 2, 4, 6... A waste for the BBC and me. Then downloads went back to the normal 1 GiB/hour.
Recently, like the last few weeks, it's doubled again with the same cause. Take PID m001x0zq. ffprobe(1) shows Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709), 1280x720 [SAR 1:1 DAR 16:9], 5058 kb/s, 50 fps, 50 tbr, 90k tbn, 100 tbc (default) Stream #0:1(eng): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 128 kb/s (default) Stream #0:2: Video: mjpeg, yuvj420p(pc, bt470bg/unknown/unknown), 192x108 [SAR 72:72 DAR 16:9], 90k tbr, 90k tbn, 90k tbc Does anyone have insights as to why this happens and what causes the BBC to return to normal? Is there anything I can do to force a sane 25 fps without dropping quality? -- Cheers, Ralph. _______________________________________________ get_iplayer mailing list get_iplayer@lists.infradead.org http://lists.infradead.org/mailman/listinfo/get_iplayer
