3gp video is blank

help40 · Post by **help40** » Wed Oct 20, 2010 12:27 pm

Hello,
seems that everything is working for me but producing 3gp video
3gp video is blank (or black I am not sure)

where to look , log file video.log tells me that video is produced
it is almost the same size as the avi and other formats , but it is blank

my server is Slackware 13.1
all libraries from wiki (detailed installation for slackware 12) are installed (but new one, which are for 13.1)
all dependences for ffmpeg are there ( or I think so )
may be I am not looking at the right log files?

Thank you in advance for help

ok , no one answer ... please just someone tell me if your Slackware installation is working and producing 3gp video

Check your ffmpeg path (options->images=>PATH_FFMPEG)

and I can play this video (yes it is bad , but may be need more configuration ... .this is not importatnt) , so it seems that my BOX can produce 3gp , but for some reason Zoneminder is not working .

I do not understand much from the logs but I see there in the first

" [image2 @ 0x807a420]max_analyze_duration reached "

what to do ?
