研究方向
The issue reports that when a playlist has multiple audio streams (e.g., 'Russian' and 'English'), the player incorrectly shows only 'Default' and 'English'. Investigation should focus on how the flashls parser handles EXT X MEDIA tags with TYPE=AUDIO, particularly the interplay between DEFAULT=YES and the NAME attribute. The code likely resides in the HLS manifest parser, possibly in files like 'HLSParser.as' or similar. Examine the logic that builds the audio track list and how it assigns the 'Default' label. Also check if there are any known fixes or discussions in the issue comments.
