subtitle embed issue

[cyburgee]

There is an issue with embedding subtitles if the video format downloaded does not include audio. Here is the output of my command:

$ youtube-dl -v -f 135/134/136/133/18/22/43/5 --embed-sub --write-auto-sub -o "/Users/ceburger/Movies/youtubes/b301c582-1ba7-4fc1-b628-838b3f91d807.%(ext)s" https://www.youtube.com/watch?v=eCPjR-94p3U

FFmpegPostProcessorError

The issue is a conflict with the format I specified which does not include audio and the ffmpeg command that specifies that the audio stream be copied. If you remove the '-c:a copy' from the line:

ffmpeg -y -i /Users/ceburger/Movies/youtubes/8f979ccd-2206-4b93-87fc-5aef22f0ff07.mp4 -i /Users/ceburger/Movies/youtubes/8f979ccd-2206-4b93-87fc-5aef22f0ff07.en.srt -map 0:0 -map 0:1 -c:v copy -c:a copy -map 1:0 -c:s:0 mov_text -metadata:s:s:0 language=eng -f mp4 /Users/ceburger/Movies/youtubes/8f979ccd-2206-4b93-87fc-5aef22f0ff07.mp4.temp

then it'll work properly.

It will work in the next version, thanks for the report!
