FFMPEG SCALE TO 1080P WINDOWS

woke up to a bazillion false events where the bottom half of the screen goes blurry which usually happens if ffmpeg isnt happy with some settings I have chosen I know vlc can be used for transcoding streams so may try get the cameras working with libvlc then see if I can get it to scale the feed down before handing it over to the zoneminder capture daemon.Įvolotion wrote:Another followup.

FFMPEG SCALE TO 1080P WINDOWS

I have yet to play with the cameras built in triggering but would very much like to keep everything in zoneminder as it works really well, and provides a central location for configuration rather than finding a windows laptop to load IE to load the proprietary camera configuration application. this is an annoying limitation in the camera so I cannot process on the sub feed. Sadly when the camera main feed is set to 5MP, the sub feed is disabled. The shutters open directly onto a main road with lots of passing traffic and foot-fall. Washout on the door is an issue as pointed out, however at night anyone entering is nice and clear, and when the shutters are open (when a junkie is most likely to be an oportunist and grab something) the camera adjusts and the view out to the street is lovely and clear. It is usually best to keep exterior doors, windows, and light sources out of the field of view, but I don't know how easy it would be for you move the camera.Īppreciate your time, am fairly new to zoneminder and cctv in general. Oh, and because you've got the camera pointing at a door, the image at the door will get washed out anytime someone goes through it. If you want the higher resolution camera to record based on motion in the lower resolution feed, then link the two cameras.Īlternatively, you could add a PIR motion detector in that room to trigger recording. Edit your motion zone to cover only the areas you are interested in. Set the high resolution camera to monitor mode, and then set the lower resolution to modect mode. The camera may require a different url for each stream. To analyse at a lower resolution than what you view, program two monitors for the same camera. I would not expect anything larger than those dimensions to work, but then again I've never tried. The link I posted shows ZoneMinder's hard-coded maximum dimensions are 2048x1536. Knowing what distro you are on, and what version of ffmpeg and/or vlc you have, would help too. Screenshots of your general and source tabs are preferred. If you need further assistance, we need to see exactly how you programmed these cameras. Use VlC player to determine the exact resolution if you have not already.

Since most cameras can support multiple streams, one can do tricks with two monitors, using two different streams at two different resolutions, to achieve different results.Īlso note that, you've got to tell ZoneMinder the exact resolution, to the pixel, or you can get cropping or duplication or no image at all. To answer your question, ZoneMinder does not modify the dimensions of the incoming stream so any scaling has to be done in the camera. I've never tried to exceed that, but I certainly would not expect anything larger than that to work properly.

ZoneMinder is hard coded to the following maximum resolution in the source code:

With cameras running at 1080p the load average hovered around. even with both cameras set just to record the load average is above 2. The cheaper these multi mega pixel cameras get the more of this will crop up I imagine, as is at 10fps the system has a load average of 3-3.5 with one core occationally going flat out tho the load is usually fairly well balanced. So what Im asking is, isthere a way to scale the camera output before recording/monitoring or inspecting for motion detection? Im not a total noob with coding and scripting but is this even achievable before I go poking around? at 5mp native the image isnt the best but scaled to 1080p it is really sharp.

rescaling the 5mp output is a lot sharper and clearer than running the camera at 1080p also. Have 2 5mp cameras throwing data at a little J1900 quad core celeron, Origionally bought the cameras with the intention of just running them at 1080p however noticed that when set to this the image crops rather than rescales so you loose a lot of the field of view.

Not a feature request (as im sure the devs have their hands full!!) but looking for a suggestion how to achieve.
