Muxing klv metadata with splitmuxsink

[cbourget]

Hi there,

I'm trying to develop a pipeline which could mux a metadata stream (klv) and
a video stream into multiple mpeg video file.
For the moment I have the following working pipeline which uses mpegtsmux
and filesink :

gst-launch-1.0 udpsrc uri=udp://224.0.0.1:5001 ! application/x-rtp,
enconding-name=H264, payload=96 ! rtph264depay !\
muxer. udpsrc uri=udp://224.0.0.1:5000 ! meta/x-klv ! muxer. mpegtsmux
name=muxer ! filesink location=test.mpg

This pipeline works perfectly but I also need the extra functonnality
provided by the splitmuxsink element.
But as far as I know this element does not seem to handle klv metadata.
Nonetheless I tried the following pipeline :

gst-launch-1.0 udpsrc uri=udp://224.0.0.1:5001 ! application/x-rtp,
enconding-name=H264, payload=96 ! rtph264depay !\
muxer. udpsrc uri=udp://224.0.0.1:5000 ! meta/x-klv !\
muxer. splitmuxsink muxer=mpegtsmux name=muxer sink=filesink
location=test-%05d.mpg max-size-bytes=104857600 async-handling=true
mux-overhead=0.05 message-forward=true

But when I run this pipeline I get the following error :
WARNING: erroneous pipeline: could not link udpsrc1 to muxer with caps
meta/x-klv

Is there a way to link the udpsrc for metadata to the muxer in the
splitmuxsink?

Thanks in advance for all suggestions!
Best,
Charles

Not sure if that works already.

Have you tried meta/x-klv,parsed=true as well? That's what mpegtsmux
wants according to gst-inspect.

But I'm not sure if it'll work already with that or if we'd need to add
another request pad template to splitmuxsink.

Cheers

Hi Tim,

I tried your suggestion and it gave me the same error :
WARNING: erroneous pipeline: could not link udpsrc1 to muxer

When you say add another request template you mean in the code for the
splitmuxsink plugin. Is this a merge request I could do to the codebase?

Thank you for your help,
Charles

Yes, that would require code changes in the splitmuxsink plugin and/or
the application - you'll probably have to do something with the "muxer-
pad-map" property, see example pipeline in

https://gstreamer.freedesktop.org/documentation/multifile/splitmuxsink.html

(You might be able to hack it that way even without modifying
splitmuxsink, not sure)

Cheers
