以下管道生成一个3kb.ogg文件(我认为它只是一个空容器)：
gst-launch-1.0 --gst-debug=3 filesrc location=test.raw
! 'audio/x-raw, format=S16LE, channels=1, rate=32000'
! audioconvert
! vorbisenc
! oggmux
! filesink location=test.ogg
以下是调试输出：

当我添加这个wav编码/解码时，我得到了一个好的.ogg文件：
gst-launch-1.0 --gst-debug=3 filesrc location=test.raw
! 'audio/x-raw, format=S16LE, channels=1, rate=32000'
! audioconvert
! wavenc
! wavparse
! audioconvert
! vorbisenc
! oggmux
! filesink location=test.ogg
调试输出：

所以我的问题是：第二条管道是什么，有wavenc！wavparse，假设缺少第一个，是否有更直接的方法来指定它，或者第二个形式实际上是"正确"的方法？
第一个管道很好，因为它与testaudiosrc(audio/x-raw-int)一起工作我假设您未压缩的音频文件必须是未压缩的WAV文件
https://en.wikipedia.org/wiki/List_of_codecs#Audio_compression_formats
Wavenc可以对LPCM进行预处理，并转换为vorbisenc可以使用的东西。我怀疑vorbisenc的数据宽度需要是32或64，这可能是一个亮点。
PCM签名的16位little-endian(S16LE)>
音频转换-将音频转换为不同格式(in:audio/x-raw-int-out:audio/x-raw-int)
wavenc-将原始音频编码为WAV(in:aaudio/x-raw-int-out:aaudio/x-WAV)
wavparse-将.WAV文件解析为原始音频(输入：音频/x-raw-float输出：音频/x-verbis)
gst-launch audiotestsrc num-buffers=50
! vorbisenc
! oggmux
! filesink location=test.ogg
play test.ogg
附录：我下载了你的文件，能够确认你正在进行从16位到32位的未实现流转换。Vorbisenc只接受32位宽度。要回答你最初的问题，不，你不需要wavsparking。这是您正在寻找的高效管道，简化为宽度转换。
