Running 2.4.8 kernel, debian testing, with zoran v0.9, mjpegtools v1.4.1. Reserve about 40M at boot with a "mem=XXX" append, which has worked well for me from the beginning. Couldn't get it to work with bigphysarea patch in the afternoon I had allotted to try it, so went back to reserving highmem at boot. Fortunately, zoran's the only tool I use over there which even thinks to use highmem, so no contentions. Using the update script what comes with zoran, I made the following changes: . commented out the insmod lines for cards I don't have (Buz and LML33) . removed $I2COPTS from the insmod lines for i2c[-old] . for the insmod of ./zoran.o, the following changes: added default_input=1 (defaults to S-VHS, overridden with lavrec) changed pass_through from 0 to 1 (personal preference) changed lml33dpath from 1 to 0 uncommented v4l_bufsize AND changed from 1280 to 1296 added v4l_nbufs=32 Because I ended up choosing to capture smaller frames, I don't need as much buffer space as allocated, but this way gives me the option to grab larger on the fly. Finally, my lavrec command looks like this: lavrec -fa -in -d2 -q100 -a16 -r44100 -s -l75 -Rl -c2 -v0 filename.%02d.avi where -fa specifies .avi format -in is for NTSC on the composite input (-iN for NTSC on S-VHS) -d2 decimation 2, gives me 288x240 frame size, which actually expands well in mplayer's fullscreen playback -q100 means to go for 100% quality on the capture -r44100 is the audio sample size -s means to capture in stereo (also works if input is mono) -l75 is for 75% of the sound recording level (I have to turn mine low or the es1371 gives a very tinny sound quality; I also turned Igain down to 22) -Rl record sound from line-in -c2 maximum level for sync correction between audio and video -v0 verbosity at its lowest level With those parameters and lavrec's default maxfilesize set to 1.6G, I get about 20 minutes of capture before it creates a new file, seamless from the previous file. From there I use other mjpegtools to compress the .avi files into MPEG2 format, and by the end of the day a videotape is reduced to 3-4 CDs. FWIW, getting to this point was NOT easy; I ran into just about every problem you can imagine with software which is, essentially, still in development. But, IMO, worth much, much, much more than what it cost in hair-pulling. Hope this helps. Donna. pudge@xxxxxxxxxx
