你是用的 Station_M2_Ubuntu_20.04_GPT_eMMC_20211109_0910.img 这个固件吗？
你说 libgstreamer-plugins-base1.0-0:1.16.2-4ubuntu0.1firefly1 这个版本的插件会有问题，看你的信息，是手动更新了部分包，而不是 apt upgrade ？

我烧写固件后，apt update，apt upgrade，更新了系统的包，然后循环播放你发的视频一个多小时，并没有异常。

你把系统的包都更新下看看？apt upgrade

你好，我之前烧写的镜像是ROC-RK3566-PC-UBUNTU20.04-GPT-20211216-1031.img
换作你推荐的Station_M2_Ubuntu_20.04_GPT_eMMC_20211109_0910.img，再升级系统，就解决此故障了。
