Hi everyone,
I'm developing on the DVEVM dm6467t evaluation board, and I have some problems
with the demos: they display the colors turned to Magenta.
I capture SD signal with the capture demo, record it into a file, and play it with
the decode demo.
There's only one little problem: I feed the component output from the board
to a sony professional monitor, and the clips - wether they are displayed from the capture
feedback monitor or from the encode demo - appear with colors turned to magenta.
I have struggled with all the monitor configurations, and double-checked the
connection of the component bnc's, but nothing changed.
Do you know if there's any trick that I could be missing?
Here is the hardware and software set configuration:
- J13 connector of the dvevm dm6467t board feeded with composite signal from a SD PAL interlaced @50Hz videoclip.
- The display is a Sony PVM-14M4E.
- The capture.c code has been tweaked:
--The capture connection settings for the driver is forced by code by placing the line
cAttrs.videoInput = Capture_Input_COMPOSITE;
after all variable initialization code within capture.c.
-- To enable the autodetection of the videoStd, I placed the call:
Capture_detectVideoStd(hCapture, &videoStd, &cAttrs);
between the previously described line and the functions in charge of doing
all the buffer size and dimension calculations. This way, the code will
use correct videoStd information to calculate the buffers' size and dimensions.
-- I've Commented out the following code:
/* We only support 720P capture */
// if (videoStd != VideoStd_720P_50 && videoStd != VideoStd_720P_60) {
// ERR("Need 720P composite input to this demo\n");
// cleanup(THREAD_FAILURE);
// }
which was responsible to kick off the program if it encountered other video standards than
720P @50 and 720P @60.
I must say that, even the demos supplied in the board's hard disk that load by default if
the board boots from flash and local hard disk, display all videos in Magenta.
Can It be a hardware problem with the ths8200 ?
I'll wait your response very eagerly. Thanks!
