* sc_factor support for encoding.Corey Hickey2006-01-22
| | | | | | | | | | | | | | | | | Here's the description I'll add to the mplayer man page: --- Causes frames with higher quantizers to be more likely to trigger a scene change detection and make libavcodec use an I-frame (default: 1). 1-16 is a sane range. Values between 2 and 6 may yield increasing PSNR (up to approximately 0.04 dB) and better placement of I-frames in high-motion scenes. Higher values than 6 may give very slightly better PSNR (approximately 0.01 dB more than sc_factor=6), but noticably worse visual quality. --- Original idea from Michael; patch by me.
