Hello, everyone, I've rechecked pretty much everything, found an easy way to connect the camera directly to a PC (I'll update the info at the wiki page), installed GStreamer and everything is working fine. I haven't really studied GStreamer's documentation to feel comfortable about changing the parameters, but that will come with time.
So now I can see and debayer the live streaming at a lower resolution, as expected. (an observation: the documentation on "how to install" and run GStreamer is quite good and the examples work. I have an issue on compiling for 32bits, where is the best place to get in touch with them? for 64 bits everything if fine). As to recording, I noticed that when I fix a video to be, say, 1024x768 in camvc, I refresh Elphel's page in Firefox/Iceweasel and that information is updated in the "disk recorder" section. I notice, however, that when I set camvc to have: Video Streamer: on; Limit the frame rate: on; Frame rate limit: 25 fps; Mantain the frame rate: on. Up there, right below the icons, it shows me this: 1024x768 @ 63.591 (in blue color, as expected) fps --- 47k. I mention this just to be sure I'm passing the right information. Now, this is what the web page shows me when I update it: Filename: - Image Resolution: 1024 x 768 JPEG Quality 80 % Framerate: 63.754 fps Record Time: - File Size: - Data Rate: - Data Rate: - The question is: if I fixed my framerate to be 25 fps, why doesn't it update here? Also, I see at the recorded videos that they are being recorded at this same fps, see below mplayer's (edited) output: livre@laika:~/Desktop$ mplayer http://192.168.1.9:var/hdd/1335633763_711797.mov Playing http://192.168.1.9:var/hdd/1335633763_711797.mov. [lavf] stream 0: video (mjpeg), -vid 0 VIDEO: [jpeg] 1024x768 24bpp 63.694 fps 0.0 kbps ( 0.0 kbyte/s) I guess that by fixing this issue, we'll be quite ready to do a first testing recording. =) Also, I will update my CF card then. It will give us a lot of mobility. So, I'll wait for your advice on which card exactly shoulf we buy. I believe a 8GB will be good enough, but it can be a 16GB. I also found the tests we made here quite important, so I'll also update this info at the wiki.
