ダンプ-歯ぎしりとの分割も助けにはならない：ffmpegの後にビデオなし（この回答：https://stackoverflow.com/a/21023110/630169）をサウンドを得る

Answer 1

このbashスクリプトは、私を助け：

#!/bin/bash 

SWFFILE=$1 
MP4FILE=${SWFFILE%.*}.mp4 
TMPFILE=$(cat /dev/urandom | tr -dc 'a-zA-Z' | fold -w 32 | head -n 1).bin 
TMPWAV=$(cat /dev/urandom | tr -dc 'a-zA-Z' | fold -w 32 | head -n 1).wav 
TMPMP4=$(cat /dev/urandom | tr -dc 'a-zA-Z' | fold -w 32 | head -n 1).mp4 

# create raw-dump 
GNASHCMD="dump-gnash -1 -r 3 -v -D $TMPFILE -A $TMPWAV $SWFFILE" 
OUTPUT="$(exec $GNASHCMD)" 

# extract parameters 
WIDTH="$(echo $OUTPUT | grep -o 'WIDTH=[^, }]*' | sed 's/^.*=//')" 
HEIGHT="$(echo $OUTPUT | grep -o 'HEIGHT=[^, }]*' | sed 's/^.*=//')" 
FPS="$(echo $OUTPUT | grep -o 'FPS_ACTUAL=[^, }]*' | sed 's/^.*=//')" 

# create raw, uncompressed mp4 file 
mplayer $TMPFILE -vo yuv4mpeg:file=$TMPMP4 -demuxer rawvideo -rawvideo fps=$FPS:w=$WIDTH:h=$HEIGHT:format=bgra 

# create compressed mp4 with ffmpeg 
ffmpeg -i $TMPMP4 -i $TMPWAV $MP4FILE 

# clean up 
rm -rf $TMPFILE 
rm -rf $TMPMP4 
rm -rf $TMPWAV
