I'm trying to add subtitles to an AVI using handbrake. The subtitles are stored in an .srt file. The output file is MP4. After I run the conversion everything completes without error but when I watch the video subtitles aren't showing. I have tried checking the different options for the subtitles, but it doesn't make any difference. How can this be fixed?
Specific to handbrake idk, but here's a sample mencoder command
