[Mjpeg-users] strange bitrate report from dvdview

2003-09-03 Thread William R Sherman
Hello, My main question isn't specifically for mjpegtools, but I think it's of interest to this group, and also I think I'm more likely to get a good answer here. It's about the values I'm seeing from the dvdview program recommended here a few days ago -- and since it seems development on dvdvie

Hi Bernhard, I appreciate the input. A question: how do you measure frame drops while recording to /dev/null ? Thanks, Jon > Hallo > > > It's the Tyan S2460 "TigerMP". > After that board came the TigerMPX (S2466) ? > I have the tiger MPX board but use zoran cards. At least in my case it > seem

Hallo > It's the Tyan S2460 "TigerMP". After that board came the TigerMPX (S2466) ? I have the tiger MPX board but use zoran cards. At least in my case it seem that the 2.6.0 test4 kernel workes better with the board and the CPU's disks. I have had less framedrops in my first test. But that can al

Hi! I really like mpeg2enc, works like a charm. But I recently started to wonder. Under that Other OS there is a program called tmpgenc. www.doom9.net refers to it a lot. When you encode to SVCD with it you can user multi-pass vbr where you specify a max bitrate and an average bitrate (max being n

Hello... I've tried to get the new mplayer to play some mjpeg (.mov from lavtools) and some dv (.avi, which I'm not really sure how my friend made). The problem is that with all interlaced input material it dies with a SEGV, because the functionpointer rgb24toyv12 is NULL. But it is ok if the
