KLV metadata creation

[Alejandro Carrera]

Hey,

I am trying to create a file with video, audio and metadata for some testing. I have created the following pipeline, however I am uncertain how to incorporate a metadata stream. 

gst-launch-1.0 videotestsrc is-live=true do-timestamp=true ! videoconvert ! queue ! x264enc bitrate=2000 ! mpegtsmux name=mux ! filesink location="test.mp4" audiotestsrc is-live=true ! queue ! voaacenc ! mux.

Cheers,

Alejandro

Hey

What kind of sink needs to be used for metadata streaming? I can parse a file containing metadata but I can't seem to find a plugin like autovideosink for metadata. 

gst-launch-1.0.exe filesrc location=metademo.ts ! queue ! tsparse ! tsdemux ! meta/x-klv ! filesink location=klvextract.log

Do I need to create a custom sink to read the information?

I have the feeling no-one here is sure how to answer this question! :-)

I suggest asking upstream at
https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel

Once you know the answer, get back here if you have difficulty in
translating into Java.

Best wishes,

Neil

You need to add an AppSink with KLV capabilities for the KLV pad

Hey

Making some progress with it, though I am running into some issues. How can I set the pipeline to verbose / debug? Hoping to take a better look under the covers to see what is happening. 

Cheers,

Alejandro
