Hi Pawel, Thanks for the quick response. > Is it possible that your userspace is not always queuing the same > userptr memory areas with the same v4l2_buffer index values? No, userptr is always consistent with the index. In fact, when we dump the captured buffer (Transport Stream) in this case, kernel space data and user-space are different. When that TS is played, macroblocks are observed from user-space and not from the kernel space dump. Although, user-space bad data is random, but, I have never seen kernel space dumped TS as bad. > In other words, if you have 2 buffers in use, under userspace mapping > at addr1 and addr2, if you queue addr1 with index=0 and addr2 with > index=1 initially, > you should always keep queuing addr1 with index=0 and never 1, etc. Yeah! this is the same rule which is being followed. > Also, what architecture are you running this on? ARM Cortex A9 SMP Regards, Divneil -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
