- The timeshift program can not be played after downloading without force refresh ,becuase of a problem of xhr access-control with disk cache see :https://lists.w3.org/Archives/Public/www-archive/2017Aug/0000.html (solved by add Access-Control-Allow-Origin in response via extension or see https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Allow-Origin CORS and caching ->set Vary: Origin in response?)
- Failed to download recorded on firefox nightly and firefox for android nightly

How it works?
The authentication of pc(html5) version radkio validates user's location via ip address.
However the android version of radkio validates user via geolocation provided by GPS(if possible),not via user's ip.
So why don't we use the authentication method of android version in pc to bypass ip check?
The authentication includes two step:
-
auth1
request : platform_info , user_id
response : a token to be valid, full_key_offset ,partial_key_length
-
auth2
request: token ,platform_info ,user_id, a parital key generated by full key and offset , connection type (in android), gps location(in android)
response: Your location (and your token is valid for only this location) / OUT
In the pc version,the full key is simplely placed in the javascript code in
apps/js/playerCommon.js:player = new RadikoJSPlayer($audio[0], 'pc_html5', 'bcd151073c03b352e1ef2fd66c32209da9ca0afa' /*full key*/ ...
However the android version's full key is protected by native dynamic librarys.Obviously the key is much longer than that in pc version.
-
-
But how do you generate the partialkey/how do you get fullkey?
By reversing android dynamic library,You can get the fullkey from .data segment after bypassing the root check ,emulator check and lots of anti-debugging tricks and waiting for itself to repair the .data segment.

-
Using ffmpeg.js (based on Emscripten:an LLVM-to-JavaScript compiler) concating ts segments to avoid 5s problem in mediaplayer.Note:size is about 13MB. (depercated : just drop id3 tags and simplely concat adts strem)
-
Fake request headers more similarly (such as remove cookies and set accept,user agent,and etc) to avoid detection (partially done) due to the limitation of extension , cannot captialize some header's key
-
Automatic switch location , no need for manually choice. (consider not supporting)
-
Add recording function? (find solution on firefox -> webRequest.filterResponseData() and localstorge/chrome.storage -> downloads.download URL.createObjectURL(BlobObject), chrome may use xhr to save data , double trafic?) the right way to download data uri https://stackoverflow.com/questions/40269862/save-data-uri-as-file-using-downloads-download-api/40279050
how to merge? (src site use hls.js to play m3u8 and aac) seems that directly concat is enough
