Hi,
HW: DM365 board
SW: dvsdk_dm365-evm_04_04_00_19 with Linux kernel 2.6.37.
Referring to VPSS guide of DM365, ISS available in DM365 is similar to that of DM814x Centaurus. On Centaurus with IPNC RDK, implementation of Links were useful to tap the data at various points. Since both ISS are similar, I assume there are certain ways to dump the data at different points. Below are the few steps I would like to explore.
I need some quick hints on software hooks to access this data in dvsdk_04_04_00_19
- input---->IPIPEIF--->ISIF----->SDRAM. How to dump the data to SDRAM via ISIF, without passing it to IPIPE and Resizer?
- input file on file system or SDRAM---->IPIPEIF--->ISIF-----IPIPE-->RSZ. How to read the data from the file instead of sensor or any other input interfaces?
- Is there any test application available with dvsdk to validate the above path(case-2)?
Issue History:
I am trying to run a simple gstreamer use case to capture using TIDmaivideosrc and dump yuv data to the file. I am able to capture the data, but data is more blueish and looks like one of the color component is completely missing(I am not sure). To debug this, I tried to run tvpxxx_ccdc_loopback_mmap test app. This test app catures the data correctly. By investigating the IOCTL calls we found that TIDmaiVideoSrc and tvpxxx_ccdc_loopback_mmap Test app uses same IOCTL calls and parameters passed to each IOCTL calls are same!! Wondering Why gstreamer is unable to capture the valid data.?
Only Major difference between gstreamer path tvpxxx_ccdc_loopback_mmap path is Resizer . SO I want to give a try on Resizer settings once.
Appricate Any help/suggestions on this.
