 Posted: Fri Nov 13, 2009 11:24 pm Post subject: Subtitle transcoding with mediatomb (piggyback ride) |
 |
|
Hi guys
For more than a year I've tried on and off to get subtitles to work with mediatomb, streaming to a PS3. There is a direct guide on the wiki on how to do it, but it just won't work for me. I hope I remember to mention everything, I've tried so many different things. This is the guide: http://mediatomb.cc/dokuwiki/transcoding:transcoding#piggybacking_subtitles_in_your_stream
I'm using ffmpeg for the ordinary mkv -> mpg transcoding, and that works great (after much headache and work), and I'm trying to use Mencoder to get the subtitles thing working. This is my config.xml:

This is my mediatomb-mencoder-srt:
| Code: | #!/bin/bash
srt="$1"
output="$2"
# filename must be of the form "movie name.XX[X].srt" or "movie name.srt"
base_name="$(echo $srt | sed 's/\..\{2,3\}\.srt$//' | sed 's/\.srt$//')"
extensions="avi mp4 mpg mov"
for ext in $extensions ; do
input=$base_name.$ext;
if [[ -e $input ]]; then break; fi
done
exec mencoder "$input" \
-oac lavc -ovc lavc -of mpeg \
-lavcopts vcodec=mpeg2video:keyint=1:vbitrate=200000:vrc_maxrate=9000:vrc_buf_size=1835 \
-vf harddup -mpegopts muxrate=12000 \
-sub "$srt" -font "/usr/share/fonts/dejavu/DejaVuSans.ttf" -subfont-autoscale 2 \
-o "$output" |
It should be like the guide on the wiki, except the path to the fonts. All I get on the PS3 is the ever-so-known "Unsupported format". So I tried if the script in a directory, and the output was:

Exiting... |
I tried removing some of the arguments/options in the script, and if I removed all of the "-lavcopts vcodec=mpeg2video:keyint=1:vbitrate=200000:vrc_maxrate=9000:vrc_buf_size=1835 \
-vf harddup -mpegopts muxrate=12000 \" it did actually work and produced a file, but the PS3 still couldn't read the file.
Has anybody gotten this to work? I'm kind of tired after hours of config file mangling.

I finally got it working by reading this thread . It seems like the
| Code: | | [mpeg2video @ 00A2F938]MPEG1/2 does not support 2997/125 fps |
is the thing to do something about. A comment in the forum says
| Quote: | Maybe I'm wrong but I think that mencoder recognize this framerates:
< 24000/1001 | 24 | 25 | 30000/1001 | 30 | 50 | 60000/1001 | 60 >
and I think there is the problem because he got this message
|
To solve this, put -ofps 24000/1001 on the line for 23.976 or -ofps 30000/1001 for 29.97 fps.
So by adding
it actually started working! I don't know what to do if the movie has another fps than 23.976 though... We'll come to that in the future I think.
