Other Parts Discussed in Thread: TVP7002

Hi,

I am trying to develop capture->encode->dump application. I have configured tvp7002 through i2c in 16 bit, embedded sync mode for 720p resolution.

Here I am able to capture, encode and dump the h264 file.But I am getting two issues with this application.

1. when I am running my application i am getting following warning message from m3vpss continuously.

"[m3vpss ] 587088: CAPTURE: Overflow detected on VIP0, Total Resets = 18"

2. I stop my application and check h264 file it seems encoding has done correctly. But when i am running the application second time, after few warning message (as above) system gets hang.

In which situation this warning message appears ? Is this because of inappropriate capture parameters ?

Thanks in advance,

Hi Shabbir,

It seems there are lot of overflows which caused hang in the capture. When it hangs, can you please print the statistics and share it?

Also are you using inline scalar for down/up scaling 720p? If you are using it for up scaling, it will overflow on every frame. Can you also make sure your input signal is stable?

Thanks,

Hi Brijesh,

Oh yes. There was a problem with input signal. It wasn't stable. Now it's working perfectly fine.

Thanks you,
