Upgrading ffmpeg
For starters, I want to state ffmpeg may need to be upgraded... http://www.ffmpeg.org/download.html
download a static build with --enable libass of your windows/linux/mac build and replace it in subsonic/transcode.
Windows Users
I suggest Zeranoe's FFmpeg build (static)
C:\subsonic\transcode
Linux Users
I suggest Burek's FFmpeg build (static)
/var/subsonic/transcode/
Setting up fonts.conf File
Windows Users Only
ffmpeg needs a font config file... create a folder named fonts in transcode ie... C:\subsonic\transcode\fonts
next make a text file in the fonts folder and name it fonts.conf
open text editor and place this in the file...
fonts.conf
- Code: Select all
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<!-- /etc/fonts/fonts.conf file to configure system font access -->
<fontconfig>
<!--
DO NOT EDIT THIS FILE.
IT WILL BE REPLACED WHEN FONTCONFIG IS UPDATED.
LOCAL CHANGES BELONG IN 'local.conf'.
The intent of this standard configuration file is to be adequate for
most environments. If you have a reasonably normal environment and
have found problems with this configuration, they are probably
things that others will also want fixed. Please submit any
problems to the fontconfig bugzilla system located at fontconfig.org
Note that the normal 'make install' procedure for fontconfig is to
replace any existing fonts.conf file with the new version. Place
any local customizations in local.conf which this file references.

Save it, and then you will need to add some environment variables.
Environment Variables
Windows Users Only
Hit the windows button and in the search type... env .... then hit enter and the env variables should pop up.
The Environment variables can also be accessed by right clicking computer or my computer properties, then hitting advanced system settings, go to advanced tab, and at the bottom will be environment variables.
in the env variables, two will need to be added...
User Variables For Admin
FC_CONFIG_DIR (this is the variable name)
C:\subsonic\transcode\fonts (this is the variable value)
and
FC_CONFIG_FILE
C:\subsonic\transcode\fonts\fonts.conf
Update Subsonic
Now that ffmpeg is updated and has access to your fonts, you will need to update subsonic war so that it will have the basefilenames interpolation string for transcoding...
subsonic-4.8-ssa-war
replace this .war with your current one, make a backup just in case.
subsonic-4.8-ssa-src src for anyone interested
Windows Users
Default is C:\Program Files (x86)\Subsonic
Linux Users
/usr/share/subsonic/ (at least for debian)
Restart Subsonic and check your jetty folder for a folder named 3434ssa (that will mean it was installed successfully)
Windows Users
C:\subsonic\jetty\3434ssa
Linux Users
/var/subsonic/jetty/3434ssa (at least for debian)
Transcoding
Now then we can move onto transcoding... First off make a folder in the directory the .war was in...name the folder sub... or if your in linux just put it in your transcoding folder
Windows Users
C:\Program Files (x86)\Subsonic\sub
Linux Users
/var/subsonic/transcode/sub
This will be the directory for all your ssa/ass subtitle files.. also let me note that a ssa/ass file is required to transcode with ffmpeg. For a fail safe, for a case theres no subtitle file, make a file in the sub folder named clean.ass with this contents
clean.ass
- Code: Select all
[Script Info]
ScriptType: v4.00+
[V4+ Styles]
Now, mainly I only use the subtitles for mkv files, because thats the only container I need it for, but you can do this for any file type as long as you provide a subtitle file.
In Subsonic... Settings...Transcode...add transcoding
name: ssa/ass
convert from: mkv (make sure any filetype added here is removed from other transcodes)
convert to: flv
Windows Users
Step 1
- Code: Select all
ffmpeg -i sub\clean.ass -n sub\%f.ass
Step 2
- Code: Select all
ffmpeg -ss %o -i %s -b %bk -s %wx%h -copyts -af asetpts=PTS-%o/TB -vf ass='sub\\%f.ass',setpts=PTS-%o/TB -ar 44100 -ac 2 -v 0 -f flv -vcodec libx264 -preset superfast -threads 0 -
Linux Users
Step 1
- Code: Select all
ffmpeg -i /var/subsonic/transcode/sub/clean.ass -n /var/subsonic/transcode/sub/%f.ass
Step 2
- Code: Select all
ffmpeg -ss %o -i %s -b %bk -s %wx%h -copyts -af asetpts=PTS-%o/TB -vf ass='/var/subsonic/transcode/sub/%f.ass',setpts=PTS-%o/TB -ar 44100 -ac 2 -v 0 -f flv -vcodec libx264 -preset superfast -threads 0 -
And done! now to test to make sure everything was done correctly / working properly! play a mkv, or whatever filetype you added and if it plays then bam! you are ready to start adding SSA/ASS files. As a note, because this is a burn in transcode, these subtitles will work on all devices, like android. cheers =]
Extracting SSA/ASS files
from a container... example...
abc.mkv
- Code: Select all
ffmpeg -i abc.mkv abc.ass
if theres more then one subtitle in the container first do the input
- Code: Select all
ffmpeg -i abc.mkv
look at the streams it will say 0:0 is video 0:1 is audio then it could have 0:2 with another audio or subtitle and so on, find the subtitle you want and do...
example of it having subtitle on stream 0:2 0:3 and 0:4 and you want 0:3... by default, it will extract the default subtitle or lowest numbered on the stream.
- Code: Select all
ffmpeg -i abc.mkv -map 0:3 abc.ass
Linux Users
To do a simple batch file...name it something like assconvert with this contents...
assconvert
- Code: Select all
for m in *.mkv
do
ffmpeg -i "$m" -y "/var/subsonic/transcode/sub/${m%mkv}ass"
done
may need to grant execution so..
# chmod 755 assconvert
then place it in the folder and do..
# ./assconvert
Windows Users
Alternatively you can also download mkvtoolnix with mkvextractgui (place the gui in mkvtoolnix)
version 2.2.2.5 can extract fonts and all other versions should be able to extract anything else.
Adding Fonts (optional)
Windows Users
Easy! All you do is get a font like [fontname].ttf and right click and install it! simple =]
Linux Users
At least for debian, fonts folder should be /usr/share/fonts
Mainly I only needed ttf, but added a folder in truetype called myfonts... ie /usr/share/fonts/truetype/myfonts
Add your ttf's or otf's or any desired font you want then in the terminal...
- Code: Select all
# cd /usr/share/fonts/truetype/myfonts
# mkfontscale && mkfontdir
# fc-cache
Trouble shooting
If you get a access denied error, first hit the play. If it still shows access denied, check the log.
If it say font config error or something stating the config file, that means of course something isnt working right with env variables (probably) Windows can be picky. Make sure the env variables and config file is exactly where I described.
If its showing something like missing .ass file or something mostlikely missing the clean.ass file, or it could be a problem with one of the characters used in the file name. I have not really looked into what characters these are and sometimes they work with some files and dont with others, it is odd but the first thing to check would be things like ! , ; ~ any of the special characters really.
If theres no sub folder in transcoding, you not be able to generate an .ass file which will generate the access denied error.
For windows, if Madsonic was not installed in the default folder, wherever it was installed,(where you to replaced the .war at) is also where you need to create the sub folder for your subtitles. By default, wherever it was installed is where the root directory is. Also take out the transcode folder in the transcode so that it says sub\ instead of transcode\sub the clean.ass will need to be moved to this directory as well.
Sometimes when converting container ssa/ass subs (older ones anyway) the .ass may have a small error... example...
random.ass
