Problem with image quality or stream authentification

Question

Hi, if i install motion with apt-get (3.2.11.1) i have a great quality of image, but i don't have a stream login. And if i install motion with svn, i have login but a poor quality image. The question is, exist any patch to add login for 3.2.11.1 or a patch to get better quality to the image for svn. Thanks any way.

Hi Pablo ,

I see in both logs a "warning" related to issues with jpeg frame decoding, are you using libv4l ?

Could you tell me more about that image quality problem ?

- only happens in saved files and stream or only in stream ?

- could you attach a screenshot ?

- Please recheck values for quality of stream and jpg in config files.

About your question it's easier to fix quality image in trunk than backport new features to 3.2.11.1
