In CCTV industry, whatever DVR or IP camera, H.264 compression format has become a future mainstream. But, only depending on watching video, it is hard for most of people to tell the difference between MPEG-4 & H.264; besides, on the market, there are “fake” H.264 DVRs! Well, here comes an easy way. When QuickTime is playing a video, you can push “Ctrl + L”. This free player from Apple would show what the format is.
在CCTV業界,無論是DVR還是IP camera,H.264漸漸成為主流的壓縮格式。但是,光是看影像,絕大多數人是分辨不出MPEG-4與H.264之間的差異;此外,業界還有不少「偽」H.264 DVR!不過,有一個簡單的驗證方法:用QuickTime回放影像時,按「Ctrl + L」,這個由Apple提供的免費軟體,就能檢閱影片的格式。
