Linux: DM8148 capture:CAPTURE Overflow detected on VIP0

Hello,

What you mean by "same head" and "different head" in your use case?
You could check this thread:
e2e.ti.com/.../315097
it is for tvp7002 but it could point you what you should check in "overflow detected..." case.
I would also recommend you to check this link:
e2e.ti.com/.../426680
You could also search in the e2e for similar issue.

yes,I checked this thread, but i don't use tvp7002 , the fpga send video directly. "the same head"means fpga send two chn "the same video","the different head" means fpga send one chn real video,the other is simulate video.
