f4m downloader producing broken video files on daisuki.net

[fb39ca4]

I have created an extractor for daisuki.net, https://github.com/fb39ca4/youtube-dl/blob/daisuki/youtube_dl/extractor/daisuki.py

It uses _extract_f4m_formats, and seems to complete the download fine. However, the resulting files are unplayable. Here is the output from mpv. Perhaps the stream is encrypted, and youtube-dl's implementation does not handle that?

It's DRM protected.

Here is an example of the manifest. Do you know which part gives information about the DRM?

This isn't the usual FlashAccess DRM which puts tags in the manifest; it seems to be the custom Akamai DRM. The only piece of information available on it seems to be a forum post by the author of the AdobeHDS.php script, and it may be outdated.

Ok. I'm instead going to investigate using HLS for daisuki, but I need to figure out how to get youtube-dl to use the proper cookies when downloading m3u8 files.

Daisuki has moved to HLS and I've implemented it in 9bd05b5.
