cimbar_recv cannot extract pic from cimbar_send

[lhx0217]

am i doing something wrong？  I use one of the outputfigs for recv test, but cimbar_recv extract nothing. int bytes = dec.decode_fountain(img, sink, shouldPreprocess); bytes is always 0.

Test without camera is ok.

Usually to troubleshoot, I save a few frames (e.g. cv::imwrite(img, "/tmp/foo.png")) and look at them individually to figure out if there's an obvious reason why they aren't decoding.

One possibility is that the color decode is failing. The algorithm for that part of the decode is not very good (I'm working on improving it now...)
