August 28, 2000. Linux driver for Miro/Pinnacle Systems Inc. DC10plus and some DC10 cards. Version 0.5: http://www.cicese.mx/~mirsev/Linux/DC10plus/linux-dc10plus-driver-v0.5.tar.gz Now it seems to be almost ready for 2.4 kernels. It has minor changes and the source now can be compiled for kernels 2.2.14 and above, including 2.4 series. I've tested this v0.5 driver with 2.2.16 and 2.4.0-test6 kernels (of course, you need to compile modules separately for each kernel, if you wish to use the driver with either version). To compile and run the driver under 2.4.x kernel you need to choose video for Linux support as well as Zoran ZR36060/ZR36067 chipset support in kernel configuration. Actually, Zoran driver from the kernel is not used, the support for this chipset is required only to enable i2c-old.o module compilation. This code is still beta. It is known to have problems with older DC10 cards equipped with ZR36057 instead of ZR36067 in newer DC10plus. When the driver loaded into memory it can be used with lavrec -d1 command (see lavtools description below) to capture video only once. The second attempt will fail. DC10plus cards don't have this problem. I'm still looking into this issue, however, if you find a solution, please, let me know. General information: Driver homepage: http://www.cicese.mx/~mirsev/Linux/DC10plus/ This is a driver for DC10plus capture cards from Pinnacle Systems Inc. It also works with many old Miro DC10 cards with SAA7110A TV decoder and ADV7176 TV encoder (please, make sure that your card has these chips, otherwise the driver will not work). The driver is Video4Linux compliant and contains extensions to provide hardware support for full motion MJPEG compression and decompression. Since this driver is a derivative from the driver for Buz Iomega cards written by Dr. Rainer Johanni, http://www.johanni.de/munich-vision/buz/ they both have compatible API. I hope that this API will become a standard. At least, there is another driver, for LML33 cards, which shares the same API: http://www.mlb.org/ Formats supported by DC10plus driver: PAL/SECAM: up to 768x576 at 25 full frames per second; NTSC: up to 640x480 at 30 full frames per second. The JPEG compression ratio is adjustable, so the data rate can be varied from 6-7 MBytes/s down to 1-2 MBytes/s depending on the required image quality. Hardware compression Since the card provides hardware compression, even low end machines can be successfully used for movie capture and playback. I've tested the driver with 2.2.14 kernel running on 233 MHz Pentium MMX with 64M RAM on 430TX motherboard and with 10GB IDE drive from Western Digital Corp. Tested applications: XawTV to watch video on your computer monitor. kwintv the same (you might need to use option lock_norm=1, see the description in Changes section below). lavtools To record and playback AVI or Quicktime files. Note: you will need patched version, lavtools-1.2p2 to support new features of this driver. Please visit driver homepage for more info. Broadcast2000 reportedly (I didn't try that) can accept movies recorded by lavrec for editing and then edited movie can be played back by lavplay program. MainActor 3.53 also can accept movies recorded by lavrec for editing.
