gstreamer 音乐可视化错误
您好，我尝试使用以下命令在 gstreamer 中可视化音乐文件：
gst-launch filesrc location=file.mp3 ! decodebin ! audioconvert !
tee name=myT myT. ! queue ! autoaudiosink myT. ! queue ! goom !
colorspace ! autovideosink
但我收到此错误：“可能存在时间戳问题，或者这台计算机太慢。”

假设这与线程有关，我尝试了以下命令：
gst-launch filesrc location=file.mp3 ! decodebin ! audioconvert ! tee name=myT
{ ! queue ! autoaudiosink } { tee. ! queue ! goom ! colorspace ! autovideosink }
但随后它给出了以下链接错误：
** (gst-launch-0.10:5308): WARNING **: Trying to connect elements that don't share a common ancestor: tee and queue1
0:00:00.125000000 5308 003342F0 ERROR GST_PIPELINE grammar.tab.c:656:gst_parse_perform_link: could not link tee to queue1
WARNING: erroneous pipeline: could not link tee to queue1
谁能告诉我出了什么问题吗？谢谢
hi I am trying to visualize a music file in gstreamer using the following command:
gst-launch filesrc location=file.mp3 ! decodebin ! audioconvert !
tee name=myT myT. ! queue ! autoaudiosink myT. ! queue ! goom !
colorspace ! autovideosink
But I get this error : "There may be a timestamping problem, or this computer is too slow."
Pipeline is PREROLLING ...

Assuming this is something to do with the thread, I tried the following command:
gst-launch filesrc location=file.mp3 ! decodebin ! audioconvert ! tee name=myT
{ ! queue ! autoaudiosink } { tee. ! queue ! goom ! colorspace ! autovideosink }
But then it gives the folloiwng link error:

Can anyone tell what is wrong? Thanks

我无法给你确切的答案，因为我没有安装Windows。
为了调试它，请使用您的第一个管道（在 Linux 中）。将参数 -v 与 gst-launch 一起使用，并将元素标识放在 autovideosink 之前。这将打印通过元素标识传递的缓冲区信息，寻找任何奇怪的东西。
您也可以尝试使用 directdrawsink 而不是 autovideosink。我要做的另一个测试是使用 audiotestsrc 生成音频。
请记住，如果您发现错误，您可以在 gnome bugzilla 中打开错误报告，以便 GStreamer 开发人员意识到存在问题。即使您可以自己修复它并发送补丁。
I cannot give you an exact answer because i don't have windows installed.
For debugging this use your first pipeline (in linux works). Use parameter -v with gst-launch and put element identity just before autovideosink. This will print buffer information that passes through element identity, look for anything strange.
Also you could try to use directdrawsink instead of autovideosink. Another test that i will do is to generate the audio with audiotestsrc.
Remember that if you find a bug you can open a bug report in gnome bugzilla so GStreamer developers are aware that there is a problem. Even you could fix it yourself and send a patch.

我还观察到，如果将
autovideosink替换为xvimagesink或ximagesink，时间戳问题显然似乎得到了解决。For

I also observed that if you replace
