# 2015/05/11 とりあえず動いた

gst-srt-tts.sh

#!/bin/sh
WIDTH=960
VIDEO_HEIGHT=540
SUBTITLE_HEIGHT=100
FONT_NAME="selif"
VIDEO_PATH="$1"
SRT_PATH="${1%.*}.srt"

gst-launch-1.0 videomixer name=mix sink_1::ypos=${VIDEO_HEIGHT} ! xvimagesink \
filesrc location="${VIDEO_PATH}" ! queue ! decodebin name=decode \
decode. ! videoscale ! video/x-raw,width=${WIDTH},height=${VIDEO_HEIGHT} ! mix.sink_0 \
decode. ! pulsesink \
videotestsrc pattern=black ! video/x-raw,width=${WIDTH},height=${SUBTITLE_HEIGHT} \
! subtitleoverlay name=overlay font-desc="${FONT_NAME}" ! mix.sink_1 \
filesrc location="${SRT_PATH}" ! queue \
! subparse subtitle-encoding=UTF-8 ! tee name=srt ! overlay. \
srt. ! udpsink

使い方

tts_serverを起動しておく

python3 tts_server.py

別の terminal を開いて test.mp4 test.srt がある場所で

gst-srt-tts.sh test.mp4

で日本語字幕の表示と読み上げをしながら動画再生する

参考にしたところ
