Note the relationship between the source memory address and the target address when copying the address, that is, whether the source memory address and the target address are crossed.
1. If there is no crossover, you can directly copy the data in a loop.
2. If there is crossover, there are also two types of crossover.
First:
In this case, Src> = DST SRC
Second:
In this case, DST> SRC

SRC. Left = Bx; //
In fact, opencvMany functions contain a mask.Many people do not know how to use the parameter, as if they ignore it in actual use, opencv designers can ignore it by default ).
Here, I will introduce you to a detailed analysis of the mask in a common function cvcopy.Hope you can give us some guidance.
CvcopyThis function is very familiar. You can use it a lot. Haha ......The following content is a PDF file in the installation folder of opencv.

DSD is the technical principle. Dsdiff short for DFF is the file suffix DSF is also the file suffix, they mean, but one is the name of Philips, the other is Sony, the file is not compressed, suitable for dual-channelFor multi-channel, because the volume is too large, it is compressed. This is the DST file format. T
2:00am, on daylight saving Day because no 2:00am,job will be executed? Or in the winter time 1:59am execution, the second 1:00am execution, job will not error? The following time periods are required for special attention in our testing capabilities, which are guided by these time periods and can be used to cover most scenarios.
Points to note:

In the front, literally speaking, this function is just to produce a avpacket reference (reference);
Personally, this function can help you to a certain extent, I understand the meaning of each parameter of avpacket structure;
int Av_packet_ref (Avpacket *dst, const avpacket *SRC)
{
int ret;
ret = av_packet_copy_props (DST, SRC); Thi
day, and this time calculation is complex:If the current time is: 1986-09-13 23:00:00, add 1 hours to 1986-09-14 00:00:00If the current time is: 1986-09-13 22:00:00, add 2 hours to 1986-09-13 23:00:00, since 1986-09-13 23:00:00 is daylight saving time, the clock needs to be dialed back.The daylight saving time algorithm in a programming language is very complex because daylight savings are different in each timezone.===============================================================================
accurate than GMT in terms of" world standard Time ". Its error value must be kept within 0.9 seconds, if greater than 0.9 seconds by the International Earth Rotation Transaction Central Bureau in Paris to release a leap second, so that UTC and the Earth's rotation period is consistent. So basically the nature of UTC emphasizes the world time standard, which is more precise than GMT, but there is no difference between the function and accuracy of GMT and UTC for current models.
