Re: Prebuffering for HD Video Playback CIFS/NFS - Help needed!

Finally I could compile anything I need.
I have an executable and some .so-s. I will copy them to the TV via scp.
However I am not sure what should be exactly the right location? Any help would be appreciated.
depends on how do you like to distribute the package and on its components (just libs, helper tools or/and scripts).
you should build an ipkg archive with http://tldp.org/LDP/Linux-Filesystem-Hierarchy/html/ structure,than its easy to build images and move files
into tvs structure or you build the archive to fit into /mtd_tlib/

I have built and debuged the tool on ubuntu and it worked.
Now I have copied it into the TV from USB and was able to run mount.readahead (this is the name I gave to the app), it found the libraries, but I get Segmentation fault. I assume this happens because of

Code: Select all

 {
   aio_buffer_sz = 8 * 1024 * 1024,
   aio_consume_window = aio_buffer_sz / 2,
   debug_readahread_aio = true
 };
 char aio_buffer[ aio_buffer_sz ];
At least I have got seg fault on ubuntu as when I have tried to increase the buffer size to 16 MB. Is there any limitation for the maximum size of an array or of a class on arm? If yes, is there a way to increase it?
ansi standard has some limits, are you shure this should be a buffer and not an array to buffers?
can you pls zip your code (with some documentations) and post it here.

thnx
arris

Why don't you plug it via cable? 100Mbit is enough for HD movies.
Or if you don't want cables upgrade that dongle & your router with 802.11n, which promises 300 Mbit connection.
