6 years ago The frame_crc_write_packet function in the framecrcenc.c file has a problem with the calculation of the value of crc.
The frame_crc_write_packet function in the framecrcenc.c file has a problem with the calculation of the value of crc. The reason for the problem is that when hw is decoded, data acquisition is required through the syncsurface operation. At present, the data after surface synchronization has a problem at the 12th frame.
