Hard to say without at least the output from gst-launch-1.0 -v. We don't
know what type the input stream is or what decoders get plugged, etc.

Maybe the output from the video decoder is not compatible with what
avenc_mpeg4 requires for some reason.

(Also, dumping the output from avenc_mpeg4 into a file does not give you
a .ts file, but that's related to your issue)
