Gstreamer: how to link decodebin to encodebin? (error: failed delayed linking some pad of …)












0















Naively, I am trying to link decodebin to encodebin:



$ gst-launch-1.0 filesrc location="/tmp/sound.wav" ! decodebin ! encodebin profile="application/ogg:video/x-theora:audio/x-vorbis" ! filesink location="/tmp/sound.ogg"
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
WARNING: from element /GstPipeline:pipeline0/GstDecodeBin:decodebin0: Delayed linking failed.
Additional debug info:
./grammar.y(510): gst_parse_no_more_pads (): /GstPipeline:pipeline0/GstDecodeBin:decodebin0:
failed delayed linking some pad of GstDecodeBin named decodebin0 to some pad of GstEncodeBin named encodebin0
ERROR: from element /GstPipeline:pipeline0/GstDecodeBin:decodebin0/GstWavParse:wavparse0: Internal data stream error.
Additional debug info:
gstwavparse.c(2293): gst_wavparse_loop (): /GstPipeline:pipeline0/GstDecodeBin:decodebin0/GstWavParse:wavparse0:
streaming stopped, reason not-linked (-1)
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
Freeing pipeline ...


Surely, there is something missing. What is it?



Note, this works:
gst-launch-1.0 filesrc location="/tmp/sound.wav" ! decodebin ! audioconvert ! vorbisenc ! oggmux ! filesink location="/tmp/sound.ogg"
