Capture overflow

Ivan Nardi
Intellectual 445 points

Hi guys,
I have a issue with video capture running the first mcfw demo.
After the program has been running for a while (some minutes, or a couple of hours), some overflow are detected on VIPs and the images freeze on both hdmi outputs and on the SD one (then I think is a capture issue really).

Sometimes the freeze occurs after the first overflow, sometime the first overflow is correctly managed and the issue appears after the second (or third...) one.

No "strange" logs are displayed in both cases. For example:

 [host] MCFW_IPCBITS:VcapVencVdecVdis_ipcBitsSendFxn:INFO: periodic print..
 [host] MCFW_IPCBITS:VcapVencVdecVdis_ipcBitsSendFxn:INFO: periodic print..
 [host] MCFW_IPCBITS: Callback function:VcapVencVdecVdis_ipcBitsInCbFxn
 [host] MCFW_IPCBITS:VcapVencVdecVdis_ipcBitsProcessFullBufs:INFO: periodic print..
 [host] MCFW_IPCBITS:VcapVencVdecVdis_ipcBitsRecvFxn:INFO: periodic print..

 [m3vpss ]  49210684: CAPTURE: Overflow detected on VIP0, Total Resets = 6
 [m3vpss ]  49210702: DEI     : Loading Up-scaling Co-effs
 [m3vpss ]  49210703: DEI     : Co-effs Loading ... DONE !!!
 [host] MCFW_IPCBITS:VcapVencVdecVdis_ipcBitsSendFxn:INFO: periodic print..
 [host] MCFW_IPCBITS: Callback function:VcapVencVdecVdis_ipcBitsInCbFxn

By the way, the process (the A8 one, at least) is not hung, i.e. I am able to exit gracefully

I'm using RDK 1.09.00.16.
I have read similar thread in TI forums, but I haven't found a proper solution.

Any helps? Thanks in advance.
Best regards
