It seems to struggle with keeping up with the data rate:\r\n\r\n```\r\n(cheese:5562): cheese-WARNING **: Can't record audio fast enough: gstaudiobasesrc.c(866): gst_audio_base_src_create (): /GstCameraBin:camerabin/GstAutoAudioSrc:audiosrc/GstPulseSrc:audiosrc-actual-src-puls:\r\nDropped 10584 samples. This is most likely because downstream can't keep up and is consuming samples too slowly.\r\n```\r\n\r\nOn master branch (eeb2935ac5a74eeb3d2e32f311fd6e6ef743e78c) I can capture 1280x720 without any warnings / dropped samples. But with this PR, I have to reduce the resolution to 320x240 (or else the recording will have lots of dropped video/audio samples => really poor video)."}}
