Site request: GYAO! (Yahoo Japan)

[BlackHoleSpain]

Please, could you add support for unrecognized urls at gyao.yahoo.co.jp ?
Examples of videos I would like to download:
http://gyao.yahoo.co.jp/player/00091/v10158/v0994000000000542985/
http://gyao.yahoo.co.jp/player/00101/v08932/v0871400000000541256/

The site is Japan-only, so you need to access through a proxy located there.
Any japanese proxy I have tried from several public listings allows perfect replay in the web browser.
However, it seems that youtube-dl doesn't recognize these Yahoo URL's and fails in generic extractor.

The verbose log is as follows (proxy address hidden for security):

Using developer tools inside Chrome, you can find transport stream files being loaded in network history, but they seem encrypted, since there are no recognizable MPEG headers. A 256-bit key is also loaded, but I don't know how the Flash player deals with those data. I hope you are able to check this site.

Thanks in advance!
