The job to do now is to verify that the file is correct. I found the VLC player on the network for a few days. What else. 264 A bunch of players won't work in the test. I began to suspect that my compression was faulty.

When using the Development Board, it is found that the RTC time is always set to November 30, 2015, no matter how you set it, use hwclock-W or program to modify the RTC chip, the modified time and RTC time are both correct, but after the power failure is restarted, the time is changed to November 30, 2015.Through analysis and search, it is found that the timestamp in the/etc/directory is suspicious, and its

/usr/lib.In the practical application of embedded Linux systems, 1 and 2 are often used. Some relatively simple embedded systems use 4 or 5 paths to regulate dynamic libraries. 3. It is rarely used in embedded systems because many systems do not support lD. So. cache.The steps 4 and 5 are very simple. You only need to put the required libraries in/lib or/usr/lib to solve the problem that the library cannot be found. However, for larger systems, not easy to manage.According to the actual situatio
