Leaning how to program WDTV live

[spixon]

Hi all,

I new in this wdtv live homebrew. I would like to do my own homebrew.
Can someone help me to give basic how to start.

I already download WDTV_Live_GPL_code_package_1.06.15_V and compile latest WD GPL code.
Successfully manage to install and test but it only have flikr on it.
for starting I like to add youtube.

hope can get help from expert.

Thanks

Maybe I'm not reading your message correctly - but isn't youtube available within the base WD firmware?

kroetkroet really

I just try to compile latest wd live source code and when I flash my own compile
i cannot find youtube.

I will try again maybe got error.

The GPL version of dmaosd has a lot of features stripped out. It's also missing the Paragon NTFS driver, and using NTFS-3G instead, which is much slower.

this forum provide b-rad source code?

Define "b-rad source code". If you are talking about the DNA sequence of the developer named b-rad, I doubt he's open sourced. Wether his mom or his dad hold the copyrights, no one knows. I think in civilized countries like the USA, the rights get transferred to the person on his 18th birthday.

If you're talking about the firmware called WDLXTV, everything is in the SVN repo. dmaosd is closed source, so there is no source code for it. WDLXTV isn't built from sources, it's built from component assembly.

Thanks RMerlin for explanation

Is SVN repo you're talking about - http://svn.wdlxtv.com/svn/wdlxtv-live ? Is there some guide on how to build a firmware from WDLXTV repo? (I have almost no experience on Linux, but have an intention to learn) /build contains only "version", yet I've tried to search for makefiles in /trunk with no luck.

Also, maybe someone have a clue:
1. Does all multimedia receiving-->decoding-->playback process is performed in DMAOSD or there are several components acts together?
2. Is there an access to HDMI signalling from homebrew apps?
3. Is there a disassembler/decompiler for ELF/MIPS which is capable to understand calls to dynamic libraries (like fopen, recv, select, etc.). I've tried to use REC Studio Decompiler and IDA -- they both shows an import table, but leave some garbish code which even doesn't looks like .SO-calls. Something like "*(*(r28 + -32128))();"

If you're not an experienced linux user you shouldn't attempt to pack and flash your own firmware.
Start with creating a .rootFS and boot from USB (this way you can always remove the USB drive and boot from flash even if you messed up your .rootFS and WDLXTV is not booting anymore)
http://wiki.wdlxtv.com/RootFS

1) There is more than one program involved, dmaosd and MEDIA_LOGIC, dmaosd is the main programm and OSD which send the files to play back to MEDIA_LOGIC which is the DLNA renderer on WDTV.
2) No.
3) I don't think so. You can use gdb to debug dmaosd but you would need to understand MIPS assembler. If this was an easy task (or even an easy to learn task) there would be much more hacking on dmaosd going on.
I know only 2 or 3 ppl who are capable of this and I'm not one of them so maybe what I just said is even plain wrong...
