While I don't think FFmpeg's response is a great one ("fund us or stop submitting bugs"); I think Google is being pretty shitty here. For a company that prides itself in its engineering prowess and contributions to the OSS community (as they like to remind me all the time) to behave this way is just all around shitty.

Submit the bug AND the patch and be done with it; don't make it someone else's problem when it's an OSS library/tool. A for-profit vendor? Absolutely. But this? Hell naw.
