Summary

Soop has started returning lg_cdn as the CDN identifier (previously gs_cdn).
The plugin maps CDN identifiers to *_pc_web for the return_type parameter, so lg_cdn needs to be converted to lg_cdn_pc_web as well.

Changes

  • Map lg_cdn -> lg_cdn_pc_web in Soop.CDN_TYPE_MAPPING

Reproduction

streamlink https://play.sooplive.co.kr/sirianrain/290044878

Debug log (before)

error: Unable to open URL: https://livestream-manager.sooplive.co.kr/broad_stream_assign.html (400 Client Error: Bad Request for url: https://livestream-manager.sooplive.co.kr/broad_stream_assign.html?return_type=lg_cdn&broad_key=290044878-common-sd-hls)

Debug log (after)

Available streams: 360p (worst), 540p, 720p, 1080p (best)

Is this a region-based thing? The stream works fine here from master:

Yes, it seems to be region-based.

From a KR IP, the API returns CDN=lg_cdn, and Streamlink then calls
broad_stream_assign.html?return_type=lg_cdn, which consistently returns HTTP 400 for me.

This PR maps lg_cdn to lg_cdn_pc_web, similar to the existing gs_cdn handling.
After that change, the stream works as expected from KR.

It likely works fine on master in other regions because a different CDN value is returned there.
