FFmpeg screenshot speed is particularly slow

FFmpeg is a particularly slow solution

Problem:

When using the ffmpeg command to perform some frames (about 300 frames) in a video, it is found that the speed is getting slower and slower with the frame time.

Cause analysis:

The reason for this is that "-ss" should be placed in the first parameter location due to incorrect parameter location, so that ffmpeg will directly jump to this frame, instead of frame-by-frame scanning.

Solution:

Run the following command:

Ffmpeg-y-I beijing-480p.mp4-ss 6000-s 320x180-frames 1-f image2 result.jpg

Changed:

Ffmpeg-y-ss 6000-I beijing-480p.mp4-s 320x180-frames 1-f image2 result.jpg

After testing, the execution speed of ffmpeg is changed from 8m44. 914s to 0m0. 964 s, which greatly improves the efficiency.
