Pipeline Pause/Resume Fails

[David Manpearl]

Issue: I am unable to pause and resume a pipeline.

Pause works, but I have been unable to resume playing.

Pause: gst_element_set_state(pipeline, GST_STATE_READY)

Works!

Resume: gst_element_set_state(pipeline, GST_STATE_PLAY)

Fails :(

GStreamer error: element gbxdemux, msg: Internal data stream error. {"dbg_info":"qtdemux.c(5850): gst_qtdemux_loop (): /GstPipeline:pipeline2/GstQTDemux:gbxdemux:\nstreaming stopped, reason not-linked (-1)","err":"Internal data stream error."}

Pipeline:

gst-launch-1.0 filesrc location=GOPR1568.mp4 ! decodebin name=gbxdemux ! videoconvert ! videorate ! videoscale ! video/x-raw,format=I420,framerate=30/1,width=1280,height=720 ! progressreport update-freq=2 ! x264enc ! mp4mux name=mux ! filesink async=false location=/test_media/video.mp4  gbxdemux. ! queue ! decodebin ! audioconvert ! audioresample ! avenc_aac ! mux.

Error:

GStreamer error: element qtdemux1, msg: Internal data stream error. {"dbg_info":"qtdemux.c(5850): gst_qtdemux_loop (): /GstPipeline:pipeline0/GstDecodeBin:gbxdemux/GstQTDemux:qtdemux1:\nstreaming stopped, reason not-linked (-1)","err":"Internal data stream error."}

GStreamer Version: 1.10.4

Notes:

1. async: I recently added "async=false" to the "filesink". It has not resolved the issue, and I am worried that it may allow de-synchronization of audio and video on the output.
   
2. audio: The same pipeline can be run with without audio by removing the ending phrase: "gbxdemux. ! queue ! decodebin ! audioconvert ! audioresample ! avenc_aac ! mux." Same error.
   
3. state: I have tried transitioning through GST_STATE_READY between PAUSE an PLAY. Same error.

Thanks!

Typo: Pause: gst_element_set_state(pipeline, GST_STATE_PAUSE)

(although I have tried various combinations of both)
