guvcview exported jpeg file incorrect

Asked by Andrew Kay

I have a logitech C920 webcam, and Kubuntu 14.04.

png files are saved correctly.

When I try to save a snapshot image with guvcview in jpeg format, the file is malformed

(specifically, gwenview says

"gwenview(29407) Gwenview::JPEGErrorManager::errorExitCallBack: Quantization table 0x00 was not defined
gwenview(29407): libjpeg error in src"

but I can't open the file in irfanview either, so I think it is the file that is at fault.)

You should report it as a bug and attach/link a sample file.

Can you save a new file from the web and view that ok?

converted to a bug (thanks thkrueger)

actionparsnip -- yes, I can. See bug report, I've attached an image saved by guvcview.

Can you help with this problem?
