Playing Video file from SD Card? (Linux Video Driver)

Hey all!

Ive been reading all post and based on my time calculation this should be now possible to achieve (i hope)

What i need is to load out small C++ app to Linux and make this app load on boot up. App is nothin more then video player that will look at video files on SD card and starts playing them. (Maybe we don't even need to write and app, but main goal is to read SD card and play video file in constant loop)
Is this possible?

To my understanding this should be possible as long as we can output anything from DM365 Linux to the "screen".

I was reading that there will be sources posted in 2013 and/or SDK will become available.

Any recommendations on how i can achieve my goal? Tnx!

    Hi Alex,

    Welcome to DLP & MEMS E2E Community!

    What i need is to load out small C++ app to Linux and make this app load on boot up. App is nothin more then video player that will look at video files on SD card and starts playing them. (Maybe we don't even need to write and app, but main goal is to read SD card and play video file in constant loop)

    The DM365 DVSDK will allow you to include your app in the linux filesystem and boot from SD card. The DM365 as such supports various video codecs as specified in this link- http://processors.wiki.ti.com/index.php/DM365_Codecs_FAQ , but these are  not enabled for the LightCrafter at this moment.

    I was reading that there will be sources posted in 2013 and/or SDK will become available.

    I apologize for the delay in releasing the DVSDK. It's in works and will be released by end of this month.

    Regards,

    Hey Divya, thank u for ur reply.

    If codecs are not curently available can we installnthem on our own? At this point my linux guys digging the kernel and they tell me that we need to use frame buffer to output something on the screen. When we will succeed in that we will encode video and play it. Are we in right direction?

    Booting off sd card, this will create problem as our final device assumes that user can remove sd card. Can we save image to nand? Also i noticed that after reboot all our changes are erased. How can we keep changes and also how can we build udisk and bin file? (im not linux person i dont know if this something that we should be conserned about or not)

    For dvsdk, what will be in it? I need to see if we should wait for it to be released or play around on our own. We have dealine to finish software part in 1 week from now, and so far if we get to output image to the screen from our app stand alone then we are on schedule

    Thank u!
