mencoder script problem

bbb13 · 03-25-2013, 07:44 AM

Code:

#!/bin/bash
for file
do
base=${file%.*}
ext=${file##*.}
newname=${base}"_subt".mpg
mencoder "$file" -sub ${base}.srt -subcp utf-8 -font /usr/share/fonts/msttcorefonts/arial.ttf -subfont-text-scale 2.5 -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd:tsaf -vf harddup -srate 44100 -af lavcresample=44100 -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=5000:keyint=15:vstrict=0:acodec=mp2:abitrate=128:aspect=16/9 -ofps 25 -o "$newname"  | zenity --progress --text="Working: $file" --pulsate --auto-close
done
zenity --info \
--text="Finished"

whats wrong with this script?it's supposed to convert a video file to mpeg2 and embed the subtitles.i tried it in an mp4 file and it worked.i tried in mkv and it does convert the video but doesn't embed the subs. so any ideas how should i make the script to work.with all filetypes?

Not a direct response to your question, anyway:
- as stated by the persons that did the fork of "mplayer2", "The MEncoder codebase was in very bad shape.", so it might be that you just hit a bug if it works with the target mp4 container but not with mkv.
- if you feel desperate have a look at "mkvmerge" (part of the "mkvtoolnix"-package). I usually use "mmg" (part of the same package) for target mkv-containers, which uses the same codebase as mkvmerge, and it always worked great for all kind of source formats being audio, video or subtitles.

That works for me:

embsub

Code:

#!/bin/bash

if [ "$1" == "" ]; then echo "embsub file.avi" ; exit; fi

infile="$1"
subfile="${infile%.*}.srt"
outfile="${infile%.*}.sub.avi"

string=`mplayer "$infile" -endpos 1 2> /dev/null | grep fps`

scale=`echo $string | awk '{print $3}'`
fps=`echo $string | awk '{print $5}'`

width=$scale
width=${width/x*/}
height=$scale
height=${height/*x/}

bitrate=`expr $width \* $height \* 50 \* 25 / 256`

mencoder "$infile" -sub "$subfile" -subcp utf8 -oac copy -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=$bitrate -o "$outfile"

Feel free to customize it to your needs.

When you’ll customize the script to your needs publish here the working version as well.

i would look into xvidenc and h264enc.
