When activating irq_debug in the bttv driver i notice the following error: "FBUS", // pixel data fifo dropped data (high pci bus latencies) Is there someway this can be checked in zm_local_camera.cpp so the image can be f.e. discarded , or maybe the framerate automagically decreased with a...

I am also looking into this problem. When I increase framerate witht high-resolution images i see the same problems ( 4 x bt878a ). I am suspecting the PCI bus ( standard 133 MB/s ). and f.e. 4 channels at 25 fps 640 x 480 RGB24 already give 92MB/s data which should travel the PCI bus. Switching to ...

I thought you might be interested that the latest release candidate for 1.24.0 now includes an ffmpeg monitor type which essentially implements a similar process to that described above in that any path can be assigned and that is passed directly to ffmpeg for processing. Please see the last post i...

Gentlemen, forgive me for being new to the ZoneMinder (i.e. asking stupid questions), but how do I exactly use this in an already compiled version, such as the one used in Ubuntu (from reps)? I have a camera with an mjpegb (yuvj422p) stream that I can view with ffmpeg/ffplay. Since using mjpeg give...

Wow this is great news,

I am quite busy at the moment, but i'll give it a try asap.

I indeed also see a split screen with the mpeg4, i have not seen such behaviour before. I'll try some checks to see if it is camera or ffmpeg related.

At this moment i see some problems with the rtsp code as used in ffmpeg. best solution to use rtsp camera's at the moment is the openRTSP work around: 1. create a pipe ( f.e. mkpipe /tmp/pipes/achterterrein.pipe ) 2. change owner of pipe to the user you use for running zoneminder (f.e. chown nobody ...

I have checked a "Digi-Lan CMOS network camera LAN" TV7203 which I believe is based on the same firmware as the vivo camera's. ffplay rtsp://x.x.x.x/live.sdp works fine (this is what i use in my own setup) ffplay rtsp://x.x.x.x:2010/live.sdp works fine ffplay rtsp://demo:demo@x.x.x.x:2010/...

I can compile but I can't test because I have a remote camera with a password. I have found a few mpeg4 free cameras to test: http://www.midisec.com/index.php?option=com_content&view=article&id=44&Itemid=55 So, at Hostname I use: demo:demo@midisec.com Port: 2010 Source: rtsp://midisec.c...

This is very impressive. I will take a good look at this as you may well have found a better way of doing it provided ffmpeg supports all the other little wrinkles. :D What i noticed up to now: * it takes quite a few seconds before the cam is initialized and streaming * mjpg cameras work best by ad...

I have seen there is support for mpeg4 camera's in the next version, but i have made an replacement zm_remote_camera.cpp for ZoneMinder 1.23.3 using ffmpeg for decoding, but also for the network part. As a bonus it gives me a lower load on the mjpeg camera's i am using at the moment. http://dejonge....

It is quite easy. Put a cam to record at 358x288 / 360x288. Use the cgi script to test:
cgi-bin/zms?mode=single&monitor=2&scale=86&.......< al the other vars >

I have tested at different scale factors, it is not always visible. But the above numbers showed it for me.

Hi i just fixed a smal bug in the scaling code. As fas as I can see it is in al versions from 1.21.0 up to current version. ( original image size 358x288, scale factor 86, gives an shift every line of 1 pixel ). --- zm_image.cpp 2006-05-08 14:46:53.000000000 +0200 +++ zm_image_new.cpp 2006-08-25 10:...
