Please ask your question
When loading a DRM HLS content to the Shaka Player, the second MEDIA_SEGMENT request made in getMediaPlaylistBasicInfo_ in HLS Parser causes significant delay when loading manifest by fetching the entire media segment.

In the screenshot, the second request with the size of 157MB is fetched. Is this necessary? Is there a way to workaround this?

Code Snippet:

player.configure(
drm: { 'com.widevine.alpha': <licenseServerURL> },
manifest: {
   hls: { mediaPlaylistFullMimeType: 'audio/mp4; codecs="mp4a.40.2"' }
}
}
player.load("https://test.com/v1/manifest-translator/manifests/hls/com.widevine.alpha/236a494a9b504d7f226234827468b62ac82f52a5/audio/10/master.m3u8");
...

Example manifest file:
master.m3u8.txt
