gstreamer display embedded subtitles

lachezarnikolov — Mon, 06 Jan 2014 09:44:47 GMT

Hello,

I have a file with embedded subtitles and I am trying to display them along with the picture. The file is an .mkv file with one video, one audio and three subtitle streams. Here's what vlc says about the file:

When I play the stream on my linux box using

gst-launch-0.10 filesrc location = /mnt/hgfs/work/test_videos/Tales.from.Earthsea\[h264.dts\]\[niizk\].mkv ! decodebin2 name=dec ! subtitleoverlay name=overlay ! ffmpegcolorspace ! autovideosink dec. ! overlay.

everything works correctly. However when I try to play that on the i.MX6 board using

gst-launch-0.10 filesrc location = /mnt/sdb1/kur/Tales.from.Earthsea\[h264.dts\]\[niizk\].mkv ! decodebin2 name=dec ! subtitleoverlay name=overlay ! ffmpegcolorspace ! mfw_v4lsink dec. ! overlay.

it plays the video fine but it doesn't display any subtitles. The output is:
