| Hello Team, I have a strange issue while trying to run simple transcoding application written in C++ with LibAV usage. Code is attached as a file. The application runs totally fine on M1 Macbook. Though when I run the same code in docker using linux/amd64 Debian or Ubuntu container it fails inside `avcodec_send_frame` with Segmentation fault. Valgrind shows that something very bad happens here: ==1== Process terminating with default action of signal 11 (SIGSEGV) ==1== Access not within mapped region at address 0x6F657265748B ==1== at
