Streaming without downloading from network

Altera_Forum · ‎06-30-2006

Hello all once again ...

sorry for the continuous headaches i make http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/huh.gif

I'm working on my grad. project .. it's about video decoding ..

i want to stream a LARGE video file over the network (from my PC) .. decode the stream under uCLinux .. then display the decoded frames(this final step is not yet done)

i tried loading a small video file on the FS ,, as a test.. it works fine..

but i want to test large streams .. i need to use the network ..

Hippo said that the ftp is quite easy ...

but .. as far as I know .. ftp will download the whole file !!

This is not what i want ..at ALL http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/ohmy.gif

i thought samba shares can be mounted .. and the shared files can be streamed (read) easily .. but .. i felt that the samba in uClinux is not an easy job .. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/blink.gif

can any1 help me ?? ,, any ideas ??

Thanks in advance http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

What about NFS to a linux machine....all you need is a supercheap PC, load Linux, copy your file to it, setup your NIOS board for NFS, and boot. If you already have a Linux PC you're almost there already.

While I don't have much NIOS experience, I have done a lot of other Linux development on embedded platforms and have always utilized NFS mounts. This is much easier than creating a flash image everytime something changes and is meant to work as a mounted FS, so it gets around the FTP issue that you noted. SAMBA is similar, but to act as a connection to Windows FS--which throws many more variables into the mix.

You might want to implement a tftp clien in your application. It's not very difficult, your app can

control the read requests, and there are plenty of servers you can use on unix and windoze machines.

I started writing all of this out, but I'm sure this is much more complete.

Hope this helps.
