fuzzy images on 3 of 4 cams #16

Closed skueppers closed 8 years ago

First of all thanks for your great script which runs (nearly) charming after a few pitfalls. My current problem is that 3 of my 4 cams only show a "fuzzy" picture - as well as if streaming "by default" oder "over tcp". rpisurv All in all my RasPi uses currently 50-60% CPU

Although this is not a specific problem with rpisurv maybe you have the crucial hint

Did you assign enough memory to the GPU?

If you are going to have multiple streams, add gpu_mem=512 to your /boot/config.txt

skueppers commented 8 years ago

currently running with gpu_mem=384 "only" setting gpu_mem to 512 makes the system ghastly slow

just checked: even when using only one camera the picture is "fuzzy" When trying the rtsp-URL in VLC on my workstation it runs just fine even though it than has to pass another router

What version of omxplayer are you using?

If you want to stream rtsp over tcp please add rtsp_over_tcp: true to the stream in /etc/rpisurv. See https://github.com/SvenVD/rpisurv/blob/master/surveillance/conf/surveillance.yml for an example. If you have a "smearing" effect this option may resolve it. Note that you need a version of omxplayer older then 14 March 2016 (https://github.com/popcornmix/omxplayer/pull/433) to do this.
