Edimax IP cameras

Post by lelik1 » Wed Jan 11, 2017 12:35 pm

Good day. I am a happy zm user since 2011. Back then, installing zm took couple days and could be done only from source. It required about 7 custom patches just to work. Recently I've installed 1.29 from debian backports and was genuinely surprised that it just works (well, except the db was so obsolete that zm couldn't even launch zmupdate.pl, permissions were wrong for API, no tmp folder under app - but compared to earlier days this is nothing).

Anyway, the ONLY thing that still holds me back from just installing zm from the repo - a missing patch fro edimax cameras. I found this patch years ago on some forum, but without this patch my IP cameras do not work. The reason is that cameras return content-boundary in double quotes inside http response. This is allowed by standard, but is an unusual behaviour. If there is any way to integrate this patch into main tree, life would be much easier. Thanks for all the work!
