常见的结果后处理
镜头切分
调用镜头解析之后可以拿到视频的切分点帧号,结合其他工具可以对视频进行镜头切割。
例如使用FFmpeg进行实现,相关命令如下:
# 镜头检测结果可以用来切割视频,有多种方式可以实现切割。一下代码示例通过ffmpeg分别截取视频和音频片段,最终把视频和音频整合在一起。
# 示例原始视频: DetectVideoShot1.mp4
# 镜头检测结果: "shot_frame_ids":[0,21,56,74,99,128,151,170,200,218,255,271,290,307,323,362,386,416,442,464,481,644,681,716,802,833,889,1027,1049,1075]
# 其中第八个镜头起止帧分别是170、200
# 通过ffprobe查看到视频帧率(25)和音频采样率(44100):ffprobe DetectVideoShot1.mp4
# 截取第八个镜头的图像帧,并生成8v.mp4:
ffmpeg -i DetectVideoShot1.mp4 -vf "trim=start_frame=170:end_frame=200,setpts=PTS-STARTPTS" -an 8v.mp4
# 截取第八个镜头的音频帧,并生成8a.mp4:
ffmpeg -i DetectVideoShot1.mp4 -af "atrim=start_sample=44100/25*170:end_sample=44100/25*200" -vn 8a.mp4
# 组合音频和视频
ffmpeg -i 8v.mp4 -i 8a.mp4 -c copy 8.mp4
