Sorry for the delay, I'll try to write a test case, probably I can find some
spare time the next week, but I don't think will be easy, the problem does not
happen for each buffer but happens randomically (probably when the camera burst
data), 10-15 buffers are sended with the same timestamp and after that the
stream works normally for 10-15 minutes and so on
