Internal data stream error

[Nick Kitchel]

Ok thats helpful to look into. Is it true that for each element in the middle that the src -> sink needs to match??

So the x264enc.src -> mp4mux.sink needs to match?

I wanted to confirm this because I'm struggling to figure this out.

Let me know,

Thanks,
Nick

Means incompatible CAPS.

You can try debugging by adding '--gst-debug=*:3,GST_CAPS:5'

This should hopefully give you more information on the offered and
accepted CAPS.

Otherwise it is always a good idea to simplify the pipeline in order to
test where the problem is.
Fx use a 'fakesink' or 'videotestsrc' to replace parts of your pipeline.

gst-launch-1.0 decklinkvideosrc connection=sdi ! fakesink -v --gst-debug=*:3,GST_CAPS:5

gst-launch-1.0 decklinkvideosrc connection=sdi ! video/x-raw, width=720, height=486, framerate=30000/1001 ! fakesink -v --gst-debug=*:3,GST_CAPS:5

gst-launch-1.0 decklinkvideosrc connection=sdi ! videoconvert ! x264enc ! fakesink -v --gst-debug=*:3,GST_CAPS:5

gst-launch-1.0 decklinkvideosrc connection=sdi ! video/x-raw, width=720, height=486, framerate=30000/1001
  ! videoconvert ! x264enc ! fakesink -v --gst-debug=*:3,GST_CAPS:5

gst-launch-1.0 videtestsrc ! videoconvert ! x264enc ! video/x-h264, width=720, height=486, framerate=30000/1001 ! fakesink -v --gst-debug=*:3,GST_CAPS:5

And so on...

Best Regards
