The 1.0 versions don't have gst-launch-0.10 but gst-launch-1.0. Also the
ffmpegcolorspace element does not exist there anymore but is replaced by
the (more intuitively named) videoconvert element.

Also you probably want to add a queue immediately after each demuxer
srcpad, and the above pipeline has some syntax errors. Try this:

gst-launch-1.0 webmmux name=mux ! filesink location=newfile.webm \
filesrc location=oldfile.pcap ! pcapparse ! decodebin name=dbin \
dbin. ! queue ! videoconvert ! vp8enc ! queue ! mux.video_0 \
dbin. ! queue ! audioconvert ! vorbisenc ! queue ! mux.audio_0
