[Mjpeg-users] Iomega Buz Errors
I have dual Xeon 2.4 GHz on Supermicro X5DAL-G motherboard (Intel SE7505 chipset), NVidia GeForce3 Ti200, SoundBlaster Live! and Iomega BUZ card. Input source is DirecTV S-Video. OS is RH8.0 with custom 2.4.20 kernel. I installed xawtv-3.85 and driver-zoran-0.9.1. I'm loading required modules with a script - below is the script; the lsmod; and the dmesg output. xawtv shows the screen on first boot, but screen goes all black shortly thereafter. EXCEPT - I can see a narrow band, which is part of the TV screen, at the top of the xawtv black screen. Also, I can't figure out how to get the TV audio out. The sound card itself is working, but not with TV signal. Ideas appreciated - Thx, Randy # cat Insmod_BUZ.sh #!/bin/sh insmod /lib/modules/2.4.21-pre4-ac4/kernel/drivers/i2c/i2c-core.o i2c_debug=1 insmod /lib/modules/2.4.21-pre4-ac4/kernel/drivers/i2c/i2c-dev.o insmod /lib/modules/2.4.21-pre4-ac4/kernel/drivers/i2c/i2c-algo-bit.o bit_test 1 bit_scan 1 i2c_debug 1 insmod /lib/modules/2.4.21-pre4-ac4/kernel/drivers/media/video/videodev.o insmod /lib/modules/2.4.21-pre4-ac4/kernel/drivers/media/video/v4l2-common.o insmod /lib/modules/2.4.21-pre4-ac4/kernel/drivers/media/video/v4l1-compat.o debug 1 insmod /lib/modules/2.4.21-pre4-ac4/kernel/drivers/media/video/videocodec.o debug 1 insmod /lib/modules/2.4.21-pre4-ac4/kernel/drivers/media/video/zr36060.o low_bitrate=1 insmod /lib/modules/2.4.21-pre4-ac4/kernel/drivers/media/video/zoran.o card=7 default_input=1 default_norm=1 lock_norm=2 # lsmod Module Size Used byTainted: PF saa7111 4860 1 (autoclean) saa7185 4476 1 (autoclean) zoran 127472 4 zr36060 9736 1 videocodec 7156 2 [zoran zr36060] v4l1-compat12740 0 (unused) v4l2-common 3872 0 (unused) videodev8128 1 [zoran] i2c-algo-bit8744 1 [zoran] i2c-dev 5700 0 (unused) i2c-core 17764 0 [saa7111 saa7185 zoran i2c-algo-bit i2c-dev] emu10k173288 0 (autoclean) sound 73196 0 (autoclean) [emu10k1] ac97_codec 13416 0 (autoclean) [emu10k1] soundcore 6212 7 (autoclean) [emu10k1 sound] nvidia 1592896 13 (autoclean) vmnet 26752 4 vmmon 25396 0 (unused) vpnmod194304 -1 (unused) e1000 51904 1 ide-scsi 12272 0 # dmesg etc etc --- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ___ Mjpeg-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mjpeg-users
[Mjpeg-users] Flickering DVD output
I'm trying to get a reasonable DVD/TV output, and I'm having flickering problems. I captured a PAL VHS source using a DC10+ and 1.6.1. My MJPEG file has these attributes: --DEBUG: [lav2yuv]width:768 --DEBUG: [lav2yuv]height: 576 --DEBUG: [lav2yuv]interlacing: top field first --DEBUG: [lav2yuv]frames/sec:25.000 Following the HOWTO, I tried encoding to DVD acceptable format using this: lav2yuv _30secs.eli | yuvdenoise | yuvscaler -O SIZE_720x576 | mpeg2enc -f 8 -q 7 -4 1 -2 1 -P -I 1 -N -o dvd_30secs.m2v Which I understand denoises leaving the interlacing in place, then encodes the interlaced source. Played on my DVD player and 50hz TV, it's horrible. The content is a yoga style video, which has slow (to non existant :o)) action and a pure white studio background. The background flickers terribly, and the edges of the person and equipment are ghosted and flickery. I tried adding -F to yuvdenoise and -I 1 to mpegenc, understanding this would deinterlace and produce deinterlaced output, and should therefore look bad on my TV. Actually, it looks a bit better, but is still not really usable. Any clues? My suspicions fall on the yuvscaler, which isn't described in the HOWTO, but appears to be necessary. (The example in the HOWTO gives an error message for me without it.) -- Eagles may soar, but weasels don't get sucked into jet engines --- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ___ Mjpeg-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mjpeg-users

I liked the idea so much, I started poking around the fade transition filter that comes with the mjpegtools (transist.flt). The changes necessary were fairly trivial. too trivial. It has already been implemented by the abysmally documented matteblend.flt . (which works great) $ cd mjpegtools-1.6.1/docs $ grep -i matteblend.flt * $ grep -i transist.flt * lavpipe.1:.B transist.flt -o 0 -O 255 -s $o -n $n -d 50 lavpipe.1:.BR "transist.flt -o 0 -O 255 -s $o -n $n -d 50" " # transistion" mjpegtools.1:transist.flt. mjpegtools.1:transist.flt needs to be informed about the duration of the transition mjpegtools.1:> transist.flt \-o 0 \-O 255 \-d 25 mjpegtools.1:transist.flt \-o 0 \-O 255 \-d 25 | yuv2lav \-f a \-q 80 \-o transition.avi $ matteblend.flt -h usage: matteblend.flt no params at the moment - color saturation falloff or such has to be implemented $ at least transist.flt is usefully documented using man mjpegtools or man lavpipe. matteblend.flt is used w/ lavpipe similarly to transist.flt, but with 3 input streams. I think I have a new idea for a patch... :-) -- ... oh yeah. Blue.
