[meta-freescale] No subtitles on imx6 with gstreamer

[Pierre Eliotec]

Hello,

Since my previous email, I try to install the gstreamer plugin
"Mpegtsdemux" on my board.
With the GST DEBUG DUMP DOT, I am note that the plugin "Mpegtsdemux" demux
subtitles but I have the same GStreamer-CRITICAL error as previously.

I need help to run subtitles on my video, please.

regards,
Pierre
