I will when the test is over present the 1st generation, the 5th generation and the 10th generation of the following codecs on my homepage: 1. libDV (only 2pass, as single-pass is so ugly in the 1st gen. that ... :-) 2. ffmpeg (using svn-snapshot from today.. seems to compile fine here (AMD64)) 3. Canopus-DV-Codec (this will take time until tomorrow, as I can not access this at home) > I've seen > people doing such tests with a decoder taken from libdv and encoder > taken from FFmpeg. > Oh my god... this knocks me out of my socks... ;-) No, I will use only the same codec for encoding and decoding of the images. I will by all means (for Canopus (Premiere) and libDV (Kino)) do my best, that the images remain unaltered between encoding and decoding. For ffmpeg this is easy (yuv4mpegpipe). >> FUD? ... I think, we should forget about that, OK? I never had the intention to either smash ffmpeg or any of it's developers! It supports yuv4mpegpipes :-) is fast and has -despite of some bugs- a nice quality... but really, which cool software is free of bugs? We all try but we will ever fail... *g* So, I do accept your apologize and hope that you will accept mine.
