Thanks for your suggestion. I did try the pipeline you suggested and it had no error. So then i tried the pipeline you suggested but replaced fakesink with filesink and it wrote an mp3 file that plays correctly. True i probably dont need that many queues but it still does not work without them. Any other suggestions? -James Pearson- sta...@gm... 214-538-8929 On Sep 16, 2009, at 3:45 AM, Stefan Kost wrote: > startoftext schrieb: >> Can any one here tell me why this pipeline does not work? >> >> gst-launch-0.10 v4l2src ! queue ! ffmpegcolorspace ! ffenc_flv ! >> queue ! >> ffmux_flv name=mux alsasrc device=hw:1 ! queue ! audioconvert ! >> lame ! queue >> ! mux. mux. ! filesink location=vid.flv >> >> Here is the output i get from above: >> Setting pipeline to PAUSED ... >> Pipeline is live and does not need PREROLL ... >> Setting pipeline to PLAYING ... >> New clock: GstAudioSrcClock >> ERROR: from element /GstPipeline:pipeline0/GstAlsaSrc:alsasrc0: >> Internal >> data flow error. >> Additional debug info: >> gstbasesrc.c(2334): gst_base_src_loop (): >> /GstPipeline:pipeline0/GstAlsaSrc:alsasrc0: >> streaming task paused, reason not-negotiated (-4) >> Execution ended after 37319285 ns. >> Setting pipeline to PAUSED ... >> Setting pipeline to READY ... >> Setting pipeline to NULL ... >> Freeing pipeline ... >> >> >> Funny thing is that if i change the device from hw:1 to hw:0 it >> works.
