I want to show subtitles with my web player (it supports Flash and HTML5). I'm using the MP4 format and I can add subtitles to the player with an external SRT file, but I want to embed subtitle to my mp4 videos.
I can embed subtitles with
mp4box (Windows command line tool) or the YAMB program. My desktop media player can see the subtitles but not all of them. I tried to use MeGui, put my MP4 and videos in it and select forced and default subtitle option. Then I started the program without re-encoding. It took several minutes. After this, the MeGui program is turning my MP4 to MKV without re-encoding and made my subtitle forced and default. All players can see the subtitles now, but that is not what I want, I need MP4 format. I tried to make the subtitles forced and default and make the output a MP4 with MeGui, this time the program is encoding my mp4 to MP4.
Is there anyway to embed subtitle to mp4 without re-encoding? My player can display Text Tracks embedded into MP4 files. How can I show my subtitles with my player?
