Is there an advantage of using a HARDWARE MPEG-2 Caputure card over bttv? Would this reduce CPU usage or allow for higher resolution caputure than the standard bttv based capture cards? At the moment, none whatsover. In fact, you might be at disadvantage at the moment since the drivers are largely ...

I found the "Source Type" in the "General Tab". I didn't see a "Monitor Tab". Once, I changed that, the errors went away. Thanks for the help. Now, I just need to figure out why I'm getting distorted video from /dev/video32 while /dev/video0 is working ok. I guess it's a problem related to ivtv ...

Also, the patch says to: setup new zoneminder camera ZoneMinder _exactly_ like this: Source Type : File File Path : /dev/video32 File Colours : 24 bit colour Capture Width : 720 Capture Height : 576 Where am I supposed to do this. The zonminder console has some of these options in the source tab ...

I found this interesting explanation on difference between various cards with hardware mpeg encoder. In particular between ivtv cards and other mpeg based cards. It is at : http://www.linuxtv.org/v4lwiki/index.php/Hardware_vs_software_encoders I took liberty to quote part of the above url below: Can ...

Just one question (because I know some one else might ask or worse just apply the patch and assume that it will work), How will this patch affect bttv based cards and can you run a combination of cards? The basic idea was to increase theoretical number of cams from 4 to 6. lspci: 00:08.0 Multimedia ...

now with color support.

Hello folks,

Here's a proof-of-concept patch for using IVTV cards with ZM.

cordel, Your card is based on cx2388x chip. True it also has the cx2341x, but this second chip serves merely as mpeg encoder (and sometimes decoder). As stated on http://www.linuxtv.org/v4lwiki/index.php/Cx88_devices "The cx2388x chip is the successor to the bt87x chip", this is why I said that it ...

All ZM needs from a driver is a way to get the image data in the first place really, and preferably some way of telling what it is that has been got. The YUVfunnyformat should not be a problem if it is clearly defined somewhere. This should not be very difficult. It goes something like (settings ...

ok, now I'm running 2.6.18 As before zmc will fail at ZoneMinder-1.22.2/src/zm_local_camera.cpp on if ( ioctl(m_videohandle, VIDIOCGMBUF, &m_vmb) < 0 ) { Error(( "Failed to setup memory: %s", strerror(errno) )); exit(-1); } with error zmc_dvideo32[4525]: ERR [Failed to setup memory: Invalid argument ...

ZM uses shared memory internally and not directly with drivers. So the image that ZM gets from a camera is put into shared memory by ZM and the drvier is not involved. All ZM needs from a driver is a way to get the image data in the first place really, and preferably some way of telling what it is ...

One more comment. As you may have noticed the 2.6.18 adds support for cx2341x which used to be in the ivtv driver (you still need ivtv stuff thought). I have asked Hans Verkuil <hverkuil@xs4all.nl> about raw data and shared memory and this is the reply I got : " Shared memory is not supported, nor ...
