Hello TI teams!

Please let me know, what is the best way to recieve this info-structure from FVID2_Frame* structure in real-time?

It is possible in general? If no, please let me know, that is the best way to get frame propertires enlisted below:

* standard (I mean PAL or NTSC frame)

* width

* height

* scan format (I mean interleaved, planar, semi-planar, etc..)

I need this info for correct settings in my algorithm.

ThanX alot.

If you are using DVR RDK, the ipcFramesIn link has this info associated with each frame.Some fields like scan format do not change runtime and can be got from the link by invoking the getInfo cmd after the link has been created.

ThanX alot for answer, but please, what is the best way for unequivocally to detect captired frame is PAL- or NTSC- frame?

Is this possible from System_LinkChInfo or FVID2_Frame structures?

Hi,

OR you can use FVID2_getModeInfo FVID2 API to get the mode informatio.

Hi,

Why dont you use your decoder to detect input signal and give detected mode?

Thanks,

Thanks for reply.

I need this info on !DSP subsystem side! in my algorithm for make correct setting, not into caputre driver. Please let me know is FVID2_getModeInfo() also available outside of VPSS sub-system?

If you need this information on the DSP you can typecast FVID2_Frame->appData to System_FrameInfo * . The System_FrameInfo has a rtChannelInfo structure which has details on width,height pitch. Any dynamic change in these params will be reflected in the System_FrameInfo associated with that FVID2_Frame.You can refer algLink for example usage.

Note that info on resolution (NTSC/PAL) is not known to the captureLink.CaptureLink just exports the information set by application .Application uses an external video decoder and determines the video standard.
