I don't really have an issue with the error messages so long as my image isn't flickering. I basiclly just left the behavior when dropping frames alone and just made it do that for our driver as well ias when using the pixart jpef format.On Sat, Jan 24, 2009 at 9:59 AM, GWater <[email protected]> wrote:Brian Johnson schrieb:Yes its fairly straight forward to patch libv4l to drop jpeg frames that get an error during the decode step. This is in fact already being done for the pixart jpeg format. I've attached a patch whcih should be applied to the latest version of libv4l which will also try broken frames for the sn9c20x driver. Please test it and let me know if this fixes the flickering issues.

Do you have a patch for that, Vasily? Any chance this patch gets into libv4l? GWaterMmm, can't remember that I mentioned anything about jpeg+libv4l+broken frames :)Oh, yeah sorry. Brian mentioned that hypothetically such a thing could implemented. So no patch yet. GWaterWhy are there broken frames in the first place? I get about 20 of these errors per second... TillNo living soul among us knows... GWaterI finally got to test this patch. 1. The image is good, no bad frames are shon. 2. The error messages are still there. They are a bit annoying but I'm not sure if we should suppress them. What do you think?
