more debugging. This variable supports one of two formats: more debugging. This variable supports the following format:
- `PIPEWIRE_DEBUG=<level>` where `<level>` is either a numerical log level or its - `PIPEWIRE_DEBUG=[<level>][,<glob1>:<level1>][,<glob2>:<level2>,...]` where the globs are
respective key, see below.
- `PIPEWIRE_DEBUG=<glob1>:<level1>,<glob2>:<level2>,...` where the globs are
shell globs to match on log topics and the levels are the respective shell globs to match on log topics and the levels are the respective
log level to set for that topic. Globs are applied in order and a matching log level to set for that topic. Globs are applied in order and a matching
glob overrides an earlier glob for that category. For example, glob overrides an earlier glob for that category. A level without a glob
`PIPEWIRE_DEBUG=*:E,mod.*:D,mod.foo:X` enables global error messages, prefix will set the global log level and is a more preformant version of
`*:<level>`. For example, `PIPEWIRE_DEBUG=E,mod.*:D,mod.foo:X` enables global error messages,
