NHK World - broken plugin? #981

Open mgk69 opened 9 years ago

mgk69 commented 9 years ago

Hi. My NHK World stopped working yesterday, I suspect NHK have changed how their stream works... if you click on the link to watch live it now goes to http://www3.nhk.or.jp/nhkworld/en/live/

The regex seems to match what is in the plugin but then I get an error as below:

C:\Users\Mark>livestreamer http://www3.nhk.or.jp/nhkworld/en/live/ best [cli][info] Found matching plugin nhkworld - Copy for URL http://www3.nhk.or.jp/ nhkworld/en/live/ error: Unable to parse JSON: No JSON object could be decoded ()

Just hoping you can have a look at it.

Thanks, Mark

This playlist contains different bitrates for the same resolution. This is not implemented yet by default, so you have to add name_key=bitrate to get all available bitrates / resolutions (#962).

Additionally, there is a secondary backup server for each bitrate. Some modifications are required to handle such playlists.

Thanks so much for the quick response! I don't understand any of that really but I found that using this code _livestreamer "hlsvariant://http://web-cache.stream.ne.jp/www11/nhkworld-tv/global/222714/live.m3u8 namekey=bitrate" best opens up VLC and plays - and actually looks a lot better than it used to (I think I used to only get the 660 bandwidth version).

I still think the NHK plugin might be broken though, but this gets it working again.
