Playbin -> play audio and video + record it to a file

[stic at free.fr]

I'm still not able to use inter elements ... but anyway, for now whatever i try to do i always fail with a message from decodebin element coming from playbin:
gsturidecodebin.c:930:unknown_type_cb:<uridecodebin0> warning: No decoder available for type 'audio/AMR, codec_data=(buffer)0000001164616d7270766d6d0001800001, rate=(int)8000, channels=(int)1'.

My problem is with audio.
I tried with different audio format, and whatever codec it is it says there is no decoder available for audio as soon as i try to use an autoaudiosink that is not coming from playbin as default.
So when i specify a bin to 'audio-sink' property of playbin, then it fails with that kind of error.
I do exactly the same thing for 'video-sink' and there is no issue with video. Video is properly played to the custom autovideosink inside my bin.

If I left things as default (no use of 'audio-sink') there is no error and audio is played ...

Please can anyone provide any help about this ? I'm really really desperate :/ ...

Thanks

Ok, i've never heard about inter elements but I've just seen it exists.
Is there any documentation or an example somewhere that explains how to use it ? Are there any constraints using this ?

Or would it be better (or less ugly ?) if I use a decodebin instead of playbin ?

Thanks

You'll have to use something like the inter elements and put the
encoding/muxing part into a different pipeline. You can't link any of
these together as they are in completely different bins inside playbin.
