Hi, I'm trying to record from a webcam and getting terrible performance from Cheese and problematic performance from VLC. Is anyone able to either tell me how to get one of them working properly or suggest another app that will work? Details (hardware at bottom) Cheese cheese-2.30.1-1.fc13.x86_64, nice, simple to use. Recording performance is awful. The booth framerate is fine, but as soon as I start recording it drops dramatically (going from frames per second to seconds per frame). VLC's ability to encode to the same target - Theora/Vorbis (but see below) and the fact I can do this under windows with the movie maker suggest a Cheese problem. Resolution is at 640x480 (which is what VLC and move maker are using), dropping to 355x288 is okay. This cheese bug seems to be related https://bugzilla.gnome.org/show_bug.cgi?id=564957 but not resolved. Anyone using F14 with good performance for cheese video recording? VLC vlc-1.1.7-1.fc13.x86_64. Less friendly, for a start I haven't been able to get it to capture by specifying devices in the capture dialog. If I just open capture and hit play I get video and sound. I can use /dev/video0 as the video input and after a bit of trial and error (using debug mode I realise it was using alsa device names) pulse for the audio device, but if I attempt to use the capture device advance options (with or without specifying /dev/video0): Your input can't be opened: VLC is unable to open the MRL 'v4l2://'. Check the log for details. ~/.xsession-errors has this: [0x7f2dfc0044e0] v4l2 demux error: invalid tuner -1. [0x7f2dfc008240] v4l2 access error: invalid tuner -1. [0x7f2e08008590] main input error: open of `v4l2://' failed: (null) (Or tuner 0 which is what it defaults to, tried -1 as this appears to be auto for other params) But capturing to theora/vorbis results in video and audio playing at different speeds, the default (which seems to be the ALSA hw device) has video faster than audio, capturing to the default (mp4) or webm is okay, using pulse and /dev/video0 webm video is slower than audio... and so on. This most successful approach so far is to open the device in play mode, use the 'advanced controls' record button and capture uncompressed a/v to avi the transcode later. This would be sort of endurable, but it would be nice to record transcoded and be able to adjust the recorded size (camera can go up to 1280x720). I'd also like to be able record both soundcard and webcam audio and video, but it looks like that will never happen with Cheese and may be difficult with VLC, so I may have to accept recording one separately and syncing up later.
