RE: Resizer Example

Hi Euan, I have took the Resize code from TI Demo and integrated with our application (no change is made in resizer code) . My app takes the YUV 4:2:2 data from file, give it to resizer and the output of resizer is directly written to display buffer. regards/Amaresh

RE: Resizer Example

Hi Amaresh, Have you modified the decode demo in anyway for the resizer or are you simply using the resizer to copy the capture buffer to the display? Do the other TI demo's display correctly? What format is your input video file? Was it recorded using the encode demo? Regards, Euan -Origin

SV: turn on/off the DSP

You say that the git kernel does not support any power management on davinci, but what about the MV kernel - does it support any sort of power management on the ARM? E.g. changing/bypassing the PLL to run at a lower clock frequency? More generally: has anyone tried to reduce the power consumptio

compiling applications with MV toolchain

Hi, i have some apllication which are running on x86 without any issue. But if i cross compile those application for davinci board with MV toolchain, it is getting segmentation fault. earlier i had issue with memcpy,memset. so mostly i am dealing with statically allocated memory. please a have lo

Memory_getPhysicalAddress segmentation fault

Hi, I am getting a 'segmentation fault' when using 'Memory_getPhysicalAddress' to get the physical address of the display buffers to be used by the resizer. I have copied the 'initDisplayDevice()' function from the TI demos as I have done before in another app but for some reason this time it is

Integrating examples and demos into the application

Hello all, I'm trying to integrate the dvevm examples and demos into my application. The way I'm building it is by building a library and linking it with my application. When I build the example (video_dec in my case) and the decode demo, everything links and works fine. However, when trying to bu

RE: Memory_getPhysicalAddress segmentation fault

Can you turn on ARM-side trace and send the log? Namely, set the environment var "CE_TRACE" to "*=01234567" and re-run your app. And in closing - and controversial - Memory_getPhysicalAddress() is not a supported Codec Engine API. :( Yeah, I know the DVSDK examples use them - and that's unfortu

Mixing DSP/BIOS Link and Codec Engine

I'm still at this task, looking to use dsplink's message queues in a different thread of a CE application. I'm essentially trying to merge CE's audio_copy example and dsplink's readwrite example. I've gotten the two to build happily together, requiring some evil #define's to resolve conflicting ty

RE: Mixing DSP/BIOS Link and Codec Engine

Bernard, The issue with MSGQ_transportOpen that you are facing is likely because Codec Engine already opens it for you. So you cannot open it again (you are getting DSP_EACCSESDENIED error). However, since CE has already opened it, you can directly use the MSGQ module from your application for usi

RE: regarding dsplink modules

Ashok, DSP/BIOS LINK does not support real-time preemption mode. Can you confirm that your kernel configuration is correct? In future releases, we will be supporting later versions of Linux (than the current 2.6.10), so users will find it easier to use without applying Kevin's patch. Till then, I

About the speed of usb slave in davinci

I have done a test for usb slave in davinci. Only 3MBytes/s when copy a file from host(PC) to the slave(mass storage), but when copy file from mass storage to PC, it reach to 12MBytes/s. I am confused that why there is only 3MBytes/s when copy file into mass storage(Davinci slave mode) from PC. An
