GOP Length In libavcodec

[nDman]

hi.
i have a question about gop lenght in libavcodec based encoders as QuEnc or ffdshow.
in this encoders when the gop length is big (more than 100) the file size is smaller and quality is much better (without blocks and mosquito noises).
on pc it is not a problem to play encoded files but i like know can play them on vcd/dvd players?
thanks.

sorry for my bad english.

some hardware players may play them but since a 100 frame GOP length is WAAAAAAY out of spec dont hold your breath for them all to, they wont.

I noticed that a long time ago (I use ffdshow) and I make my movies always with 500 GOP length (svcd's). My players (a sony and a new one, a no name zoran vaddis 7 based) never complained (beside sony displaying a wrong time counter). A downside is the much slower fast forward/rewind but I think is normal. But this is true only for SVCD's, I don't know about dvd's, never made one.

So the best thing is to check your player and if it works, to hope that your next player will be equally forgiving.
