Hi,
I am working with gstreamer on i.mx board. When i try to play a video file using following command, gst-launch filesrc location=Toyota.mpeg ! decodebin name=decoder decoder. ! ffmpegcolorspace ! autovideosink decoder. ! mad ! alsasink i get an error message as, Setting pipeline to PAUSED ... configure_write_channel, stream_id is 0 Pipeline is PREROLLING ... ERROR: from element /pipeline0/filesrc0: Internal data flow error. Additional debug info: gstbasesrc.c(1642): gst_base_src_loop (): /pipeline0/filesrc0: streaming task paused, reason not-linked (-1) ERROR: pipeline doesn't want to preroll. Setting piphw free: SSI 1 eline to NULL ... codec_reset_settings function is called Write Release Called codec_reset_settings function is called Read Release called snd_card_mxc_audio_playback_close FREEING pipeline ... If anyone have any idea about this error,please reply me. Thanks for the help --

Hi,

Hi ,
First check what all the plugins you have to demux the mpeg stream . And directly use them , dont use decodebin .

Hi, gstreamer-devel:
We have the same problem -- we use decodebin to play the rtsp movies. If I use: gst-launch rtspsrc location="rtsp://xxxxxx" name=d d. ! decodebin ! ffmpegcolorspace ! xvimagesink d. ! decodebin ! audioconvert ! alsasink We got the same error info: not linked (-1) If I didn't use decodebin instead of using depay & decoder, everything works well, e.g: gst-launch rtspsrc location="rtsp://xxxxxx" name=d d. ! rtph263pdepay ! ffdec_h263 ! ffmpegcolorspace ! xvimagesink d. ! rtpamrdepay ! amrnbdec ! audioconvert ! alsasink P.S: The not-linked(-1) error occurs when using decodebin doesn't happen every time. Sometimes the decodebin works well. So, Is this a bug of decodebin? Eric Zhang 2008/11/6 sudarshan bisht <[hidden email]>

Hi, gstreamer-devel:Try and use capsfilter to distinguish between your audio and your video branch for gst-launch to link to propers decodebin. e.g : rtspsrc !

Decodebin has got quite a lot of logic in it to properly figure out what the incoming stream is, what to connect, etc... If you hard-plug your pipelines... what happens when you install a new plugin ? Or the behaviour changes subtlely ? And yes, we also recommend it for embedded usage, in case you were wondering.

Hi, Aurelien:
Thanks Aurelien, it works as you said! So could you explain a little bit why we should add this extra capsfilter to make decodebin works? Thanks a lot. Eric Zhang

If you think a bit about it, it's easy enough to understand. gst-launch is completely agnostic about what all the pipeline elements do, but it somehow has to choose which sink pad to connect to which source pad of the rtspsrc. Look at the gst-launch command: gst-launch rtspsrc location="rtsp://xxxxxx" name=d d. ! decodebin ! ffmpegcolorspace ! xvimagesink d. ! decodebin ! audioconvert ! alsasink When rtspsrc creates a video source pad, gst-launch has to choose which of the two decodebins to connect to it. Since they look identical (gst-launch can't look into the rest of the pipeline, who knows what decodebin will do anyway?), gst-launch randomly connect the video source to one of the decodebins. After prerolling, the decodebin creates a source pad for the video and gst-launch has to connect it to the next element. Now, if you're lucky, gst-launch had select the first decodebin and all goes well. If you're unlucky, however, it has chosen the second decodebin, and gst-launch connects the audioconvert to the decodebin's video source pad... That doesn't work, so the linking fails. That doesn't crash your application yet. It's only when the pipeline goes into PLAYING and the source starts pushing data in the decodebin, that it turns out that the decodebin doesn't have anywhere to send the data to. That's what triggers the 'Not linked' error. When you use the depayloader and decoder explicitly instead of decodebin, the linking works correctly: gst-launch rtspsrc location="rtsp://xxxxxx" name=d d. ! rtph263pdepay ! ffdec_h263 ! ffmpegcolorspace ! xvimagesink d. ! rtpamrdepay ! amrnbdec ! audioconvert ! alsasink Now, the two branches of the pipeline are no longer identical. gst-launch looks at the caps of rtph263pdepay and rtpamrdepay to see which one matches the video source. It will therefore always select the right one. You get the same behaviour with a decodebin by providing caps explicitly.
