I am new to gstreamer, would be nice to have some example that saves to an mp4.

Currently I am testing with this, and that just generates a 100MB/s file

gst-launch-1.0 -v ndivideosrc url-address="192.168.0.215:5961" ! filesink location=test.raw

[@test /]# mediainfo test.raw
General
Complete name                            : test.raw
File size                                : 214 MiB

It depends on your source and what encoders are available on your system. On MacOS I do this to do hardware-encoding of NDI sources: gst-launch-1.0 ndivideosrc ndi-name='NDI Source Name' ! queue ! videoconvert ! vtenc_h264 ! queue ! h264parse ! mpegtsmux ! filesink location='ndi-source.ts'

Heres an updated example for the latest versions, saves a NDI stream as h264 TS using hardware encoding on a NVidia GPU:

gst-launch-1.0 ndisrc ndi-name="NDI Source" ! ndisrcdemux name=demux   demux.video ! queue ! nvh264enc ! h264parse ! mpegtsmux name=muxer ! filesink location="NDI-Source.ts"  demux.audio ! queue ! audioconvert ! avenc_aac ! aacparse ! muxer.

You probably want to use avenc_aac instead of faac. The latter produces low quality AAC.
