Raspberry 3B+ 无法播放视频流

如何解决Raspberry 3B+ 无法播放视频流

我正在尝试将 RaspBerry 3b+ 设置为投影仪的播放设备。但无论如何，我在树莓上尝试过的视频播放都无法流畅运行。该流来自 OBS 作为 mpegts 流（使用 libx264 8000kbps 编码的视频，每 125 帧有一个关键帧。音频当前编码为 opus 流）。

只要我只播放稳定的图像而没有移动，播放就或多或少很好（音频播放没有卡顿）。 但是当我播放例如电影时，图像会冻结并且声音也会断断续续。

Raspi 的显存设置为 256MB。

尽管如此，我的尝试并没有奏效。

编辑： 当我在我的 arch linux 系统上启动 VLC 时，它会流畅地播放流。
