Hello,
I have encoded a 4:2:2 yuv file and .264 output which I'm getting is 4:2:0
encoded. Which all formats are supported by DVEVM demo codes??? I've
modified the encode demo code to read from a file.
Thanks,
Varsha

In order to get the DSP-side development tool, you need to purchase the
DVSDK. Alternatively, if you have CCS 3.2 or above, you can download
most of the DVSDK components (i.e. BIOS, test bench, DVT) from the DVEVM
update website (you should have this link in your DVEVM material).
Best regards,
Vincent

Thanks for the help Vincent. But I dont have any DSPBIOS or CG tools or
C64P
compiler tools installed so that I can rebuild DSPLINK 1.30. Can I get
them
downloaded from TI website???
Thanks,
Varsha

Hi Varsha,
You will need to configure cmem so that you have large enough buffers.
To do this you will likely need to modify your memory map so that more
space could be made available to cmem. This old thread might be able to
guide you through this process:

Hello again,
cmem initializes 3 pools between 0x8780 and 0x8800. Even if I
read
only 3 frames at a time, memory of 8 MB will not be enough since I'm
allocating memory for encoded buffer at 0x87cce000 and reading raw video
frames at 0x87d0. So memory mapping has to be changed???

Thanks Vincent. After I used Memory_contigAlloc(), I'm not getting the
cache
alignment error. But I guess since I'm reading a file of size 11MB into
the
buffer, the shared buffer size is only 8MB, which is insufficient. I
read in
some archive that using cmemk module you could create physical
contiguous
buffers(OS memory 100MB and shared buffer 20MB). I have a doubt there.
Are
the changes to be made in .tcf file and recompile the CE server?
Now I'm getting the following error.

Hi Varsha,
How are you allocating the input and output buffers that are passed to
your video encoder's process call? Make sure you are
