Bug Report Video Capture not working if base resolution is smaller

[sam686]

if Settings, Video, Custom Base Resolution is set to something like 640x480, and video capture device is at bigger resolution like 720x480, then all I get is a blank screen or missing Video capture display. I was also unable to fit to screen, center the Video Capture Device to get it back while the base resolution is smaller then video capture source. Some other sources including window capture works ok with a very small Base resolution.

Only by setting the base resolution to be equal or bigger then Video capture Device resolution (720x480) I then able to get video capture source working.

I use Open Broadcaster v0.542b

Edit: adding a log file of this problem, http://pastebin.com/UqnZfDst
I see a "Warning -- DShowPlugin: Unable to find appropriate resolution" only when I have base resolution smaller then video resolution.

Edit 2: Turns out it only happens if the Video Capture Device properties have "Custom Resolution" unchecked. My video resolution only have 720x480 and 720x576. I enable custom resolution and chose 720x480 and it works ok now with smaller base resolution of 640x480 or smaller. Looks like it fails to pick the smallest possible resolution if no resolution is smaller then base resolution.

Thanks for telling me about this, there could be a bug with certain resolutions being usable. You may have to use custom as a workaround for the time being.

(Also just so you know that particular log didn't have anything pertaining to the capture device)

Well I guess it logs the device only when it works at a custom resolution.

device: ViXS PureTV Analog Video Capture,
device id \\?\pci#ven_1745&dev_2100&subsys_48b01043&rev_00#4&20bdbe28&0&00e0#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\{01ab4609-
It is a TV-in composite and S-Video analog and digital cable inputs.

This missing video capture problem and "DShowPlugin: Unable to find appropriate resolution" also happen to my windows 8 netbook with built in webcam when base resolution is smaller then 448x252, the smallest resolution my webcam can run at, unless video capture device have custom resolution enabled. Looks more like a bug in OBS DShow's automatic resolution picking. (My available webcam resolution is 448x252, 640x360, 640x480, 960x540, 1280x720)
