My experience on pre 1.0 is still images were the result of an incompatibility in the audio frequency (ie my video device versus my audio device). For instance since video can have audio, but say I chose not to use it but rather used another audio input, and the video's audio rate was 44khz, and my audio I was choosing externally was 48khz, voila everything seemed to work fine, except I'd have a still image on video. Not yet tried 1.0. Frankly, I was hoping a rework as I think qtkit is now deprecated in 10.8? Also, the qtkit plug-in seemed hardwired for 640x480 video (which kind of sucked for 720p new usb device, or even older fw devices which supported 16x9 aspect.)<br> <br><div class="gmail_quote">On Tue, Apr 16, 2013 at 2:10 PM, Jack Jansen <span dir="ltr"><<a href="mailto:Jack.Jansen@cwi.nl" target="_blank">Jack.Jansen@cwi.nl</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div style="word-wrap:break-word">I have found that qtkitvideosrc is very finicky (and I assume that wrappercamerabinsrc is just a wrapper around it).<div><br></div><div>With gstreamer 1.0 I have never managed to get a direct pipeline with both the video source and any displaying video sink to work. ximagesink always hangs on one frame, osxvideosink gives the spinning beach ball and doesn't show any frame.</div> <div><br></div><div>With gstreamer 0.10 it sometimes worked if you inserted an extra ! queue.</div><div><br></div><div>What does work is to run two gstreamer processes: one to grab the camera, then transmit over a socket to a second process, then display there.</div> <div><div><div><br></div><div>And if you are using qtkitvideosrc programmatically you *must* run your gst/gobject main loop in the main thread.</div><div><br></div><div>On 15-Apr-2013, at 04:55 , Haiming Wang wrote:</div> <br><blockquote type="cite"><span style="border-collapse:separate;font-family:Helvetica;font-style:normal;font-variant:normal;font-weight:normal;letter-spacing:normal;line-height:normal;text-align:-webkit-auto;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;font-size:medium"><div style="font-size:12pt;font-family:Calibri"> <div dir="ltr">Hi Dear Friends,<div><br></div><div> Can anyone give me some guide about my question?</div><div>"</div><div><br></div><div><br></div><div><div><div><u><b>When I used below command line:</b></u></div> <div><u><b><br></b></u></div><div><u><b> <span style="font-size:12pt"> gst-launch wrappercamerabinsrc mode=2 ! video/x-raw, width=320, height=240 ! ximagesink </span></b></u></div><div><span style="font-size:12pt"><u><b><br> </b></u></span></div><div><span style="font-size:12pt"><u><b><br></b></u></span></div><div><span style="font-size:12pt"><u><b>but I just get a still image displayed.</b></u></span></div></div><div><u><b><br></b></u></div> <div><u><b>Can anyone tell me why for the second line, I just got a still image, and how to get a video playback?</b></u></div></div><div><br></div><div><br></div><div><br></div><div>"</div><div>What's more, anyone known if there is any camerasrc and audiosrc on Android?
