我的目标，想把一个raw data音频文件，将浮点型32位转化为S16_LE格式，但是总是出错，deepseek来来回回就那么试，人已经麻了，求各位大佬帮助
这是我的命令
gst-launch-1.0 filesrc location=/data/7_1.pcm ! capsfilter caps=audio/x-raw,
format=F32LE,rate=48000,channels=8,layout=interleaved,channel-mask=0x0000007f,en
dianness=1 ! audioconvert ! capsfilter caps=audio/x-raw,format=S16LE,rate=48000,
channels=8,layout=interleaved,channel-mask=0x0000007f,endianness=1 ! alsasink de
vice=hw:0,1
下面是日志输出：
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstCapsFilter:capsfilter0: Filter caps do not completely specify the output format
Additional debug info:
