Hello, everyone. I am using gstreamer (through gst-launch) to access my v4l2 webcam (I have two - Logitech QuickCam for Notebooks Pro & Logitech QuickCam Pro 5000), both of which work perfectly fine when using video/x-raw-yuv-type pixel formats. However, when I want to capture the video using the supported image/jpeg pixel formats, which I presume would be higher quality (if I dump straight to JPEG/MJPEG files) as no implicit conversion is happening, I get framerates much lower than expected. For example, my webcams claim to support up to 30 frames per second when capturing in the image/jpeg format. But the resulting video is much, much slower. And this scales, somehow, if I change the capture framerate. So, for example, if I specify 25 fps, it's slower than the 30, and 15 is slower than 25, etc. But all of these are much slower in terms of capture than their yuv-format counterparts. Could someone guide me as to how I can find the source of this problem and/or test different settings that might work?
