mpd解析存在错误

Author: lns103Created Aug 1, 2026Updated Aug 1, 2026

链接 https://primeran.eus/manifests/argi-gorriak-d1-1-txarto-beti-bezala/eu/widevine/dash.mpd?include_tudum=true 问题：该mpd实际是两个视频，分别为logo和正片，logo的init.mp4 + 1.m4s，以及正片的init.mp4 + 1.m4s + 2.m4s +......，解析器直接组合了logo的init.mp4+logo的1.m4s+正片的1.m4s + 2.m4s +...... 导致视频损坏

附mpd内容
