linux - 无法初始化 Xv 输出

Question

我已经在我的目标板上安装了 gstreamer-1.0。当我运行以下命令时:

gst-launch-1.0 filesrc location="/home/test.mp4" ! decodebin ! videoconvert ! xvimagesink

I am getting the following output:

Setting pipeline to PAUSED ...

ERROR: Pipeline doesn't want to pause.

ERROR: from element /GstPipeline:pipeline0/GstXvImageSink:xvimagesink0: Could not initialise Xv output

Additional debug info:

xvimagesink.c(1765): gst_xvimagesink_open (): /GstPipeline:pipeline0/GstXvImageSink:xvimagesink0:

Could not open display (null)

Setting pipeline to NULL ...

Freeing pipeline ..

请提出一些使管道正常工作的解决方案。

问候，

Answer 1

嗯，你有 libxv 吗？寻找当您检查 gst-inspect-1.0 xvimagesink 时会发生什么？还有提到的库路径 (| grep Filename).. 你可以 ldd 它:

ldd /usr/local/lib/gstreamer-1.0/libgstxvimagesink.so

我也遇到了一些问题..尝试安装 libxv-dev 或 libxv1..也许 dev 更安全。
