src/libavformat/ftp.c:1122:46: warning: ‘%s’ directive output may be truncated writing up to 4095 bytes into a region of size 4091 [-Wformat-truncation=]
 1122 |     snprintf(command, sizeof(command), "RNTO %s\r\n", path);
      |                                              ^~       ~~~~
src/libavformat/ftp.c:1122:5: note: ‘snprintf’ output between 8 and 4103 bytes into a destination of size 4096
