[gst-devel] Simulating a video camera with a file

[katarina.balac at usi.ch]

Thank you very much for your answer. Unfortunately, this returns the error
ERROR: from element /GstPipeline:pipeline0/GstDecodeBin:decodebin0/GstTypeFindElement:typefind: Could not determine type of stream
Is there anything else I can try?

Thanks,
Katarina

Try:
filesrc ! decodebin | ffmpegcolorspace | theoraenc | oggmux | filesink

decodebin is an element to "Autoplug and decode to raw media"
