If it can't autodetect your card, use the card=X insmod -option with X being the card number as given in the previous section. -To have more than one card, use card=X1[,X2[,X3,[X4[..]]]] - -To automate this, add the following to your /etc/modprobe.d/zoran.conf: - -options zr36067 card=X1[,X2[,X3[,X4[..]]]] -alias char-major-81-0 zr36067 - -One thing to keep in mind is that this doesn't load zr36067.o itself yet. It -just automates loading. If you start using xawtv, the device won't load on -some systems, since you're trying to load modules as a user, which is not -allowed ("permission denied"). A quick workaround is to add 'Load "v4l"' to -XF86Config-4 when you use X by default, or to run 'v4l-conf -c <device>' in -one of your startup scripts (normally rc.local) if you don't use X. Both -make sure that the modules are loaded on startup, under the root account. - -What mainboard should I use (or why doesn't my card work) ---------------------------------------------------------- - - -<insert lousy disclaimer here>. In short: good=SiS/Intel, bad=VIA. - -Experience tells us that people with a Buz, on average, have more problems -than users with a DC10+/LML33. Also, it tells us that people owning a VIA- -based mainboard (ktXXX, MVP3) have more problems than users with a mainboard -based on a different chipset. Here's some notes from Andrew Stevens: - -Here's my experience of using LML33 and Buz on various motherboards: - -- VIA MVP3 - - Forget it. Pointless. Doesn't work. -- Intel 430FX (Pentium 200) - - LML33 perfect, Buz tolerable (3 or 4 frames dropped per movie) -- Intel 440BX (early stepping) - - LML33 tolerable. Buz starting to get annoying (6-10 frames/hour) -- Intel 440BX (late stepping) - - Buz tolerable, LML3 almost perfect (occasional single frame drops) -- SiS735 - - LML33 perfect, Buz tolerable. -- VIA KT133(*) - - LML33 starting to get annoying, Buz poor enough that I have up. - -- Both 440BX boards were dual CPU versions. - -Bernhard Praschinger later added: - -- AMD 751 - - Buz perfect-tolerable -- AMD 760 - - Buz perfect-tolerable - -In general, people on the user mailinglist won't give you much of a chance -if you have a VIA-based motherboard. They may be cheap, but sometimes, you'd -rather want to spend some more money on better boards. In general, VIA -mainboard's IDE/PCI performance will also suck badly compared to others. -You'll noticed the DC10+/DC30+ aren't mentioned anywhere in the overview. -Basically, you can assume that if the Buz works, the LML33 will work too. If -the LML33 works, the DC10+/DC30+ will work too. They're most tolerant to -different mainboard chipsets from all of the supported cards. - -If you experience timeouts during capture, buy a better mainboard or lower -the quality/buffersize during capture (see 'Concerning buffer sizes, quality, -output size etc.'). If it hangs, there's little we can do as of now. Check -your IRQs and make sure the card has its own interrupts. - -Programming interface ---------------------- - -This driver conforms to video4linux2. Support for V4L1 and for the custom -zoran ioctls has been removed in kernel 2.6.38. - -For programming example, please, look at lavrec.c and lavplay.c code in -the MJPEG-tools (http://mjpeg.sf.net/). - -Additional notes for software developers: - - The driver returns maxwidth and maxheight parameters according to - the current TV standard (norm). Therefore, the software which - communicates with the driver and "asks" for these parameters should - first set the correct norm. Well, it seems logically correct: TV - standard is "more constant" for current country than geometry - settings of a variety of TV capture cards which may work in ITU or - square pixel format. - -Applications ------------- - -Applications known to work with this driver: - -TV viewing: - -* xawtv -* kwintv -* probably any TV application that supports video4linux or video4linux2. - -MJPEG capture/playback: - -* mjpegtools/lavtools (or Linux Video Studio) -* gstreamer -* mplayer - -General raw capture: - -* xawtv -* gstreamer -* probably any application that supports video4linux or video4linux2 - -Video editing: - -* Cinelerra -* MainActor -* mjpegtools (or Linux Video Studio) - - -Concerning buffer sizes, quality, output size etc. --------------------------------------------------- - - -The zr36060 can do 1:2 JPEG compression. This is really the theoretical -maximum that the chipset can reach. The driver can, however, limit compression -to a maximum (size) of 1:4. The reason for this is that some cards (e.g. Buz) -can't handle 1:2 compression without stopping capture after only a few minutes. -With 1:4, it'll mostly work. If you have a Buz, use 'low_bitrate=1' to go into -1:4 max. compression mode. - -100% JPEG quality is thus 1:2 compression in practice. So for a full PAL frame -(size 720x576). The JPEG fields are stored in YUY2 format, so the size of the -fields are 720x288x16/2 bits/field (2 fields/frame) = 207360 bytes/field x 2 = -414720 bytes/frame (add some more bytes for headers and DHT (huffman)/DQT -(quantization) tables, and you'll get to something like 512kB per frame for -1:2 compression. For 1:4 compression, you'd have frames of half this size. - -Some additional explanation by Martin Samuelsson, which also explains the -importance of buffer sizes: --- -> Hmm, I do not think it is really that way. With the current (downloaded -> at 18:00 Monday) driver I get that output sizes for 10 sec: -> -q 50 -b 128 : 24.283.332 Bytes -> -q 50 -b 256 : 48.442.368 -> -q 25 -b 128 : 24.655.992 -> -q 25 -b 256 : 25.859.820 - -I woke up, and can't go to sleep again. I'll kill some time explaining why -this doesn't look strange to me. - -Let's do some math using a width of 704 pixels. I'm not sure whether the Buz -actually use that number or not, but that's not too important right now. - -704x288 pixels, one field, is 202752 pixels. Divided by 64 pixels per block; -3168 blocks per field. Each pixel consist of two bytes; 128 bytes per block; -1024 bits per block. 100% in the new driver mean 1:2 compression; the maximum -output becomes 512 bits per block. Actually 510, but 512 is simpler to use -for calculations. - -Let's say that we specify d1q50. We thus want 256 bits per block; times 3168 -becomes 811008 bits; 101376 bytes per field. We're talking raw bits and bytes -here, so we don't need to do any fancy corrections for bits-per-pixel or such -things. 101376 bytes per field. - -d1 video contains two fields per frame. Those sum up to 202752 bytes per -frame, and one of those frames goes into each buffer. - -But wait a second! -b128 gives 128kB buffers! It's not possible to cram -202752 bytes of JPEG data into 128kB! - -This is what the driver notice and automatically compensate for in your -examples. Let's do some math using this information: - -128kB is 131072 bytes. In this buffer, we want to store two fields, which -leaves 65536 bytes for each field. Using 3168 blocks per field, we get -20.68686868... available bytes per block; 165 bits. We can't allow the -request for 256 bits per block when there's only 165 bits available! The -q50 -option is silently overridden, and the -b128 option takes precedence, leaving -us with the equivalence of -q32. - -This gives us a data rate of 165 bits per block, which, times 3168, sums up -to 65340 bytes per field, out of the allowed 65536. The current driver has -another level of rate limiting; it won't accept -q values that fill more than -6/8 of the specified buffers. (I'm not sure why. "Playing it safe" seem to be -a safe bet. Personally, I think I would have lowered requested-bits-per-block -by one, or something like that.) We can't use 165 bits per block, but have to -lower it again, to 6/8 of the available buffer space: We end up with 124 bits -per block, the equivalence of -q24. With 128kB buffers, you can't use greater -than -q24 at -d1. (And PAL, and 704 pixels width...) - -The third example is limited to -q24 through the same process. The second -example, using very similar calculations, is limited to -q48. The only -example that actually grab at the specified -q value is the last one, which -is clearly visible, looking at the file size. --- - -Conclusion: the quality of the resulting movie depends on buffer size, quality, -whether or not you use 'low_bitrate=1' as insmod option for the zr36060.c -module to do 1:4 instead of 1:2 compression, etc. - -If you experience timeouts, lowering the quality/buffersize or using -'low_bitrate=1 as insmod option for zr36060.o might actually help, as is -proven by the Buz. - -It hangs/crashes/fails/whatevers! Help! ---------------------------------------- - -Make sure that the card has its own interrupts (see /proc/interrupts), check -the output of dmesg at high verbosity (load zr36067.o with debug=2, -load all other modules with debug=1). Check that your mainboard is favorable -(see question 2) and if not, test the card in another computer. Also see the -notes given in question 3 and try lowering quality/buffersize/capturesize -if recording fails after a period of time. - -If all this doesn't help, give a clear description of the problem including -detailed hardware information (memory+brand, mainboard+chipset+brand, which -MJPEG card, processor, other PCI cards that might be of interest), give the -system PnP information (/proc/interrupts, /proc/dma, /proc/devices), and give -the kernel version, driver version, glibc version, gcc version and any other -information that might possibly be of interest.
