What is the fine-grained topic of the following text: As my normal user, this works: ffmpeg -f pulse -i default -acodec aac foo.aac but run with sudo is fails with: default: No such process How can I run ffmpeg as a privileged user (CAP_SYS_ADMIN), since I am keen to use the kmsgrab option and still get access to sound in order to record it too? Only return the topic.
