Why "perf report" does not show function names in the second run, when used in docker?


Hello All,

I am trying to profile ffmpeg using the Linux perf command in docker. In the first run, the output is fine with all function names displayed by "perf report". In the second run, it only shows addresses rather than function names. I am using a script that runs the ffmpeg twice in a docker.

More details are posted here.

Thank you in advance.
