示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int ret = ola.CreateVideoFromImages("value", "videos/demo.mp4", 1.0, "H264");
csharp
using OLAPlug;

var ola = new OLAPlugServer();
int ret = ola.CreateVideoFromImages("value", "videos/demo.mp4", 1.0, "H264");
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
ret = ola.CreateVideoFromImages("value", "videos/demo.mp4", 1.0, "H264")
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
int ret = ola.CreateVideoFromImages("value", "videos/demo.mp4", 1.0, "H264");
cpp
var ola = com("OlaPlug.OlaSoft")
var ret = ola.CreateVideoFromImages("value", "videos/demo.mp4", 1.0, "H264")
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
ret = ola.CreateVideoFromImages("value", "videos/demo.mp4", 1.0, "H264")
text
.局部变量 ola, OLAPlug

ola = 新建 OLAPlugServer
整数 ret = ola.CreateVideoFromImages("value", "videos/demo.mp4", 1.0, "H264")
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int32_t ret = ola.CreateVideoFromImages("value", "videos/demo.mp4", 1.0, "H264");
