Asante Voyager II

Hi, I have latest ZoneMinder working with three USB webcams no problem. I just received an Asante Voyager II IP camera and its RTSP streams work with VLC and QuickTime. However, when ZoneMinder tries to parse its stream, it encounters an "event" stream type that is not "audio" or...

Thank you!

Huge improvement for people whose cameras push compressed frames into ZM for analysis.

Anyone know if this applies to Video4Linux-based cameras?

Can you test decompression (as opposed to compression) using the two different libraries?

Great info!

Thanks for showing how much faster libjpeg-turbo can be at compression. Obviously, any uncompressed frames that ZM has to write (to disk or a stream) will benefit nicely from using libjpeg-turbo over libjpeg. But I think that it could also help in decompressing raw frames from JPEG (i.e., working in...

Maybe our setups don't depend on fast code?

I was just looking at this document: http://libjpeg-turbo.virtualgl.org/About/Performance and it occurred to me that maybe certain video inputs use different JPEG code paths than other video inputs? In my case, my frames come from uvcvideo underlying V4L2, and maybe decompression is done in the driv...

Thanks again for the suggestions. I added /opt/libjpeg-turbo/lib64 to the front of my shell's LD_LIBRARY_PATH, but my shell had no LD_LIBRARY_PATH to begin with, and I also wonder if this would have any effect when issuing a start or restart with sudo /etc/init.d/zoneminder start , since the service...

Thank you, knnniggett. I assume the Ubuntu package zoneminder_1.24.2-2build3_amd64.deb was built to dynamically link to libjpeg? Not finding a way to alter the LD_LIBRARY_PATH for ZoneMinder to put /opt/libjpeg-turbo/lib before /usr/lib, I put the libjpeg-turbo file /opt/libjpeg-turbo/lib/libjpeg.so...

No difference with .deb installed on Ubuntu 10.4 amd64

I know that ZM is now using libjpeg-turbo 1.0.0 (installed from libjpeg-turbo_1.0.0_amd64.deb) instead of the standard libjpeg on my AMD64 system, but I do not see any performance improvement.

Anyone else running Ubuntu 10.4 on an AMD64 have the same or different results?
