On the image SIFTeam enigma2 extreme edition for DM.
There's a binary named gst-launch that is used to play streamed video that uses a plugin named playbin2..
This plugin has the ability to show a subtitle track, but it is not automatic, there's a flag that needs to be turned ON and it has to be turned on manually...
What we need, is that gst-launch/playbin2 plugin do this in automatic for the first track, so we need someone to modify this (We even have a tutorial to do so)..
We need this to be compiled for Dreambox 800 processor..
The deliver can be a single binary so we can freely include it just by copying it (preferred)
Or it can be a DM800 SIFTeam enigma2 extreme edition image..
I'm experienced on linux embedded systems and DVB. I believe i can do what you want. I already got information about the CPU, it's 32bit MIPS, Broadcom. I'll do my best, regards.
