How to enable the "trace" module #77
Description
I have sccessfully run the OMAF-Sample and stream 4K tiled immersive video through network.
However, I have trouble trying to activate the "trace" module and output trace data.
The "USE_TRACE" option set to "OFF" by default in "/Immersive-Video-Sample-master/src/CMakeLists.txt" has been modified to be "ON" before make, but there is still trouble output trace log files.
There is still no any trace log file exist in the docker container after video streaming.
Any help on telling what may resolve the problem will be appreciated.

Can you provide the output of
ldd /usr/local/lib/libVROmafPacking.so | grep traceto make sure library linking is correct?Also you can try to add -DUSE_TRACE=ON in this line.

@kuroneko306 Hi, I have already acquired the trace log about E2E delay. Is there anything I can help you?
BTW, @U1X6WK, have you successfully ran the shell script generate_client_bandwidth_summary.sh? I have some trouble when executing babeltrace2 ust/ > downloaded_trace.txt, i.e.,
No trace was found based on input
ust/.Do you know how to fix it? Thanks!
