vp8/vorbis encoding will stall on this stream:
https://www.dropbox.com/s/3dcgfth1rw3ifrp/str.mpeg?dl=0

same issue is with vp8/opus too.

I use this script for encoding:

echo "======== VIDEO, pass 1 ========="
date
gst-launch-1.0 filesrc location=stream.dump ! mpegpsdemux name=demux
demux.video_e0 ! mpegvideoparse ! mpeg2dec ! videorate ! \
    vp8enc threads=2 multipass-mode=1 target-bitrate=1000000 \
      multipass-cache-file=multipass.cache end-usage=vbr auto-alt-ref=1 \
      keyframe-max-dist=360 min-quantizer=0 max-quantizer=60 \
      token-partitions=2 lag-in-frames=16 ! fakesink


#  webmmux name=mux ! filesink location=out_audio.webm \
echo "======== VIDEO, pass 2 ========="
date
gst-launch-1.0 filesrc location=stream.dump ! mpegpsdemux name=demux \
  webmmux name=mux ! filesink location=out_video.webm \
  demux.video_e0 ! mpegvideoparse ! mpeg2dec ! videorate ! \
    vp8enc threads=2 multipass-mode=2 target-bitrate=1000000 \
      multipass-cache-file=multipass.cache end-usage=vbr auto-alt-ref=1 \
      keyframe-max-dist=360 min-quantizer=0 max-quantizer=60 \
      token-partitions=2 lag-in-frames=16 ! queue ! mux. \
  demux.audio_80 ! a52dec mode=2 ! audiorate tolerance=50000000 ! \
    audioconvert ! audioresample ! \
    taginject tags="language-code=ger" ! queue ! vorbisenc ! mux. \
  demux.audio_82 ! a52dec mode=2 ! audiorate tolerance=50000000 ! \
    audioconvert ! audioresample ! \
    taginject tags="language-code=eng" ! queue ! vorbisenc ! mux.
