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 -----Original Message----- From: Wan, Vincent [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 30, 2007 11:05 PM To: Varsha Kulkarni Subject: RE: cache alignment error!!! 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).

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???

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: http://www.mail-archive.com/[EMAIL PROTECTED] om/msg00876.html Best regards, Vincent -----Original Message----- From: Varsha Kulkarni [mailto:[EMAIL PROTECTED] Sent: Sunday, January 28, 2007 9:51 PM To: Wan, Vincent Subject: RE: cache alignment error!!! Hello again, cmem initializes 3 pools between 0x87800000 and 0x88000000. 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 0x87d00000. So memory mapping has to be changed??? -----Original Message----- From: Varsha Kulkarni [mailto:[EMAIL PROTECTED] Sent: Monday, January 29, 2007 10:24 AM To: Wan, Vincent Subject: RE: cache alignment error!!! 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. Encode demo started.

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 using contiguous buffers allocated by CMEM by calling Memory_contigAlloc() - suggest you look at how that's done in the original encode demo. The memory managed by CMEM should be correctly aligned on 128-byte boundary by default.
