imx8qxp H265 示例视频播放

我尝试播放h265视频文件，但无法播放。

IMX8QXP - 斯卡思间隙 - L 6.6.52

请您检查并提供播放h265视频示例文件的正确命令或软件包/库。

Re: imx8qxp H265 sample video play

你好，

由于您使用的是 Scarthgap (6.6.52) 版本，问题可能出在以下方面：

图像中不存在 v4l2h265dec。
H.265 文件不是原始基本流。
VPU固件/驱动程序未加载。
BSP 使用的解码器元件与流水线中指定的解码器元件不同。

请提供以下命令的输出结果：

壳
gst-inspect-1.0 | grep -i h265
gst-inspect-1.0 | grep -i v4l2
``

并获取 gst-launch-1.0 的确切错误消息，以尝试确定是否发生了以下四种情况之一。
