https://www.dropbox.com/s/rzn444d9sz8k8pa/stream.dump
i use this script to encode it:
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
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_81 ! a52dec mode=2 ! audiorate tolerance=50000000 ! \
audioconvert ! audioresample ! \
taginject tags="language-code=eng" ! queue ! vorbisenc ! mux. \
demux.audio_80 ! a52dec mode=2 ! audiorate tolerance=50000000 ! \
audioconvert ! audioresample ! \
taginject tags="language-code=ger" ! queue ! vorbisenc ! mux.
Already on first pass vp8enc will fail.
