使用wavparse和vorbisenc进行gstreamer转码失败

Question

我可以玩这个wav：

http://freewavesamples.com/yamaha-sy35-clarinet-c5

gst-launch filesrc location=Yamaha-SY-35-Clarinet-C5.wav ! wavparse ! autoaudiosink

所以我假设wavparse运行正常，但是 这个管道无法转码：

gst-launch filesrc location=Yamaha-SY-35-Clarinet-C5.wav ! wavparse ! vorbisenc ! filesink location=out.ogg

带有以下警告和错误

奇怪的是，错误发生在wavparse中，所以很好 当管道以音频设备接收器结束时，但没有编码接收器......

试试这个管道： gst-launch filesrc location = audio.wav！ wavparse！ audioconvert！ vorbisenc！ filesink location = out.ogg

我认为vorbisenc示例（audio / x-raw-float）vorbisenc支持（audio / x-raw-int）不支持的格式，这就是你应该添加audioconvert的原因。如果在管道中添加-v选项，则可以查看所有详细信息。
