How to add (.srt , .sub) subtitles to .flv flash movie video on Linux

If you're on Linux the questions like, how can I convert between video and audio formats, how to do photo editing etc. etc. have always been a taugh question as with it's diversity Linux often allows too many ways to do the same things.

In the spirit of questioning I have been recently curious, how can a subtitles be added to a flash video (.flv) video?

After some research online I've come up with the below suggested solution which uses mplayer to do the flash inclusion of the subtitles file.

mplayer your_flash_movie.flv -fs -subfont-text-scale 3

While including the subtitles to the .flv file, it's best to close up all the active browsers and if running something else on the desktop close it up.
Note that above's mplayer example for (.srt and .sub) subtitle files example is only appropriate for a .flv movie files which already has a third party published subtitle files.

What is interesting is that often if you want to make custom subtitles to let's say a video downloaded from Youtube on Linux the mplayer way pointed above will be useless. Why?

Well the Linux programs that allows a user to add custom subtitles to a movie does not support the flv (flash video) file format.

My idea on how to create custom subtitles and embed them into a flv movie file is very simple and it goes like this:

1. Convert the .flv file format to let's say .avi or .mpeg
2. Use gnome-subitles or subtitleeditor to create the subtitles for the .avi or .mpeg file
3. Convert back the .avi/.mpeg file with included subtitles to .flv (flash video format)

This methodology is really long and time consuming, but pitily as far as my understanding goes it's the only way to do that on your Linux until now.

To make the conversations between .flv and .avi format you will need to use the ffmpeg – (FFMpeg command line tool video converter), here is how:

– Convert .flv to .avi

debian:~# /usr/bin/ffmpeg -i input_flvfilename.flv output_avifilename.avi

– Convert .avi file to .flv

debian:~# /usr/bin/ffmpeg -y -i /path/to/your/avi/input_avifilename.avi -acodec mp3 -ar 22050 -f flv

The required overall tools which you will have to have installed on your Debian or Ubuntu Linux are:

1. ffmpeg
2. gnome-subtitles
3. subtitleeditor
4. mplayer

You will also have to spend some time to get to know gnome-subtitles or subtitleeditor, but it won't be that long until you get the idea on how to use them.

Yesterday I spend a lot of time outside with Lily. We went to the fountain we watched film at home. The film was called”Wild Hogs” it was supposed to be a fun commedy (only supposed to be). This week is going to be a taugh one.We have to present a project at Marketing Research.

I have to write a 600 words resume about International Enterprice,also we have to make a presentation in Culture. Today in the morning i was on a Liturgy again. God’s grace ishere ! The week passed without serious server issues (Thanks God). Today I checked some logs of one of the serversand I observed oddities there. I checked the crontab and I realized it’s because of a crontab. The dumped databaseis a HUGE one 2.6G (bzipped).

I asked in, and the guys there pointed me to a similar issuewhich was supposed to be an MySQL bug when dumping large database. Since the dumping databases were of a type MyISAMI ofcourse could have used mysqlhotcopy.

But in the end the solution to the problem was removing “–opt” option fromthe backup opts of mysqldump and passing “–skip-opt” to it (I suspect this would slow the dumping process a lot).But I don’t care it is much better (a slow dumping), than hanging the whole Webserver and interrupting the site’s visibilityover the Internet.

Btw I started playing Quake 2, it’s cool but a little annoying there are too many tunnels and veryoften after I kill most of the bad guys I spend a lot of time searching for keys and stuff .. :).END—–
