Hi

I have been trying to incorporate FFmpeg into RLPLite so that i can play videos through my FEZ hydra although there isn’t any useful information on the net that actually helps me in any way. Even with the libmpeg2 library, it is quite difficult as there isn’t any documentation on how to implement the library functions.

Please help . It is for a final design project and any input would be useful.

Thanks

I have had a look at those pages but unfortunately there isn’t much information there to actually implement the libmpeg2 library in keil uvision and it says look at the source code below whereas there isn’t any source code??

Is it possible to provide me with initializing the mpeg2 library on keil?

libmpeg2.axf: Error: L6218E: Undefined symbol mpeg2_close (referred from libmpeg2.o).

Looks like it was deleted by GHI from the wiki.

May be they can put it back, GHI?

ok. Thanks
how do i go about asking them to put it back?

Somebody from GHI will reply here. They are in the process of preapring/moving to a new building so it may not be “right away”. :slight_smile:

@ Gus

was the file deleted with the intent to move it to the Codeshare? Couldn’t find it there as well.

The original project was in the early days of RLP and needed major changes. We planned on updating it but never got to it.

FFmpeg is a beast and it will be very difficult to make it work, stick to libmpeg2, which is still not easy task.

Unfortunately, there isn’t much we can provide today but we want to offer a complete demo that anyone can use.

But what about the old zip file that was on the Wiki. Can we get our hand on that file?

13

been few years, not sure where it is. Will try to dig it out

14

That would be great thank you! If it hepls the file name was RLP_Video_Playback.zip and it was removed from wiki in February 2012.

15

Thanks :slight_smile: if you do find it please post it. it would really help me a lot .
