Convert mkv with subtitles

[redneon]

I'm trying to convert a few mkv files to MP4 so I can watch them on my PSP using ffmpegX.

The problem I'm having is that I can't figure out how to add the subtitles to the conversion. The mkv itself contains two audio tracks and two subtitle tracks (Japanese and English).

Change the audio track is easy as there's a drop down list I can select the track from but it seems the only way to add subtitles to the conversion is if I have an external file.

Is there no way to just use the subtitles that are built into the mkv?

I've been trying to do this same thing also with no luck. anyone figured this out? or is there a way to extract the subtitles first?

I managed to extract the subtitles using the mkvtoolnix tools.

You can do "mkvmerge -i file.mkv" to list all the tracks that are contained within the mkv file which gives you an output like this:

File ’file.mkv’: container: Matroska
Track ID 1: video (V_MS/VFW/FOURCC, DIV3)
Track ID 2: audio (A_MPEG/L3)
Track ID 3: audio (A_VORBIS)
Track ID 4: subtitles (S_TEXT/UTF8)
Track ID 5: subtitles (S_TEXT/UTF8)

Then you can do "mkvextract tracks file.mkv 4ubtitles.srt" to extract the subtitles.

I did this to extract the subtitles and when I open up the .srt file in a text editor it looks fine. However, when I try and load these subs into ffmpegx and encode no subtitles appear on the video so I have no idea what I'm doing wrong.

Anyone have any idea?

Burning the subtitles onto the video with ffmpegX is a mplayer/mencoder feature. The PSP presets do not use mplayer/mencoder.

You would be better off trying to do it with Perian and Decoding with QuickTime.
