erroneous pipeline

[Kip Warner]

Hey list,

Can anyone help me get the following correct for gst-launch-1.0? I'm
getting an "erroneous pipeline: could not link audioconvert0 to wavenc0
error" if I swap the x-raw-int for x-raw,format=int:

    $ gst-launch-1.0 filesrc location="song.mp3" ! decodebin ! audioconvert ! audio/x-raw-int,format=int,channels=1,rate=44100 ! wavenc ! filesink location=/tmp/dec-QCgBTc

Thank you,

Thanks everyone, but figured it out. The format should be set to S16LE.

"int" is not a valid format. You probably want something like 16bit
signed integer ? If so, the format name is "S16LE". Follow this link
for a complete list of formats:

https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-b
ase-libs/html/gst-plugins-base-libs-gstaudio.html#GstAudioFormat

In caps string syntax, we remove the namespace GST_AUDIO_FORMAT_.

cheers,
Nicolas
