Fw: GStreamer

Hi,

 

I am encountering this error while executing an mp3 pipeline:

Don't use ffdec_mp3. Use either mad or flump3dec.

This happens when you compile gst-ffmpeg against an external ffmpeg
library (instead of using the snapshot we ship with gst-ffmpeg). If you
do that, you're on your own. We only support gst-ffmpeg against the
internal snapshot (if this is a distro package, you might want to take
this up with whoever provided the package).

I think this is fixed in a newer liboil.

negotiation problem: this usually means either that your pipeline is
wrong, or that you're missing a conversion element somewhere, or that
some element is getting buffers with no caps.

Try putting a typefind or mp3parse element after filesrc. Better even:
use decodebin instead of making up your own pipelines.

Cheers

you should use an mp3 parser element (mp3parse) to feed ffdec_mp3 decoder:
filesrc ! mp3parse ! ffdec_mp3 ! audioconvert ! audioresample !
directsoundsink
