For an application that does not load a VVAS GStreamer plugin, the logging bridge is not installed. VVAS core uses its normal logging configuration:
export VVAS_CORE_DEBUG=5 # Log level: 0=NONE, 1=ERROR, 2=WARNING, 3=FIXME, 4=INFO, 5=DEBUG
Route logs to a file:
export VVAS_CORE_LOG_FILE_PATH=$PWD/vvas_core.log
Route logs to console:
export VVAS_CORE_LOG_FILE_PATH=CONSOLE
By default, standalone VVAS core logs are routed to syslog (/var/log/syslog or /var/log/messages).
