Recognizer stopped, Java heap space

[sofia]

Hello

For the last two days I have tried to use the video recognizer, sometimes the process ends without errors, but in the xml file the tiers are not created, only the header:
<? xml version = “1.0” encoding = “utf-8”?>
<TIERS xmlns: xsi = “http://www.w3.org/2001/XMLSchema-instance” xsi: noNamespaceSchemaLocation = “./ avatech-tier.xsd” />

Other times, the process is interrupted, the report indicates that the problem may be related to java and memory:

Any ideas?

It seems the recognizer extension is running out of memory while reading log messages. You could try again by setting “Adjust amount of log messages” to “low”. And you could try to increase the amount of available memory by opening the file “recognizer.cmdi” which is located in the folder ELAN/extensions/clam-hhi-hand-head-tracking. Open it in a text editor, look for a line starting with ‘runWin="java AvatechClamClient …’ (or runMac or runLinux) and insert a string like the following:
-Xmx1024m
so that the start of the line reads like:
runWin="java -Xmx1024m AvatechClamClient …
This sets the max heap size to 1024 Mb, you could increase this if you have more memory available.
I’m not sure if this will work, but it is something to try.

Thank you very much, I did your recommendation. But the problem is that the tiers are not created: the output xml file only size 1 KB and only shows the header: <?xml version=“1.0” encoding=“utf-8”?>
<TIERS xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance” xsi:noNamespaceSchemaLocation="./avatech-tier.xsd"/>
