화면 녹화를 위해 Kazam을 설치했습니다. 비디오 캡처는 좋지만 오디오 품질이 좋지 않습니다. 그래서 더 좋은 마이크를 샀어요.
새로운 마이크는 Audacity와 같은 다른 프로그램과 함께 사용하기에 더 적합하지만 3.5mm 대신 USB 입력이 있으며 Firefox 및 Kazam과 같은 일부 프로그램에서는 이를 인식하지 못합니다. 따라서 저는 Pulseaudio Volume Control을 설치하고 새 마이크를 사용하여 각 애플리케이션에 대한 오디오를 녹음하도록 구성해야 했습니다.
이제 Firefox는 Audacity 및 Skype와 마찬가지로 내 마이크를 인식하지만 Kazam은 더 큰 문제에 직면합니다. 녹음을 중지하려고 할 때마다 작동이 중단됩니다! 그래서 실제로는 아무것도 녹음할 수 없었습니다. Kazam을 다시 설치해 보았습니다. 이것은 도움이 되지 않습니다.
디버그 모드에서 Kazam을 실행해 보았고 다음과 같은 결과를 얻었습니다.

기기 자체가 아닌 기기의 모니터를 사용하도록 Pulseaudio 볼륨 조절을 설정하면 녹음을 중지하고 파일을 저장할 수는 있지만 재생할 수는 없습니다. 내가 얻을 수 있는 것은 1초의 침묵, 비디오 없음뿐이며 Kazam은 임시 0바이트 .movie 파일을 삭제할 수 없습니다.
