一、首先,分享两个命令: 视频第一帧提取:ffmpeg -i [videofile] -vframes 1 -q:v 2 -f image2 [imagefile] 音频重采样:ffmpeg -i [audiofile] -ar 16000 [audiofile] 说明: -vframes 表示提取的第几帧,获取第一桢则后面的值为1,如果后面的值大于1,那么最后的[imagefile]不能指定一个文件,不然会...
直接复制，保证视频轨道无损，只把音频轨道编码成aac，之后封装成mp4格式。

2. How to Extract Images from a Video Using FFmpeg The following command is used to extract individual frames from a video file (in this case, “video.flv“) and save them as separate image files namedimage1.jpg,image2.jpg,and so on. ...
Additionally, ffmpeg will usually need to copy the decoded frames from the GPU memory into the system memory, resulting in further performance loss. This option is thus mainly useful for testing. -hwaccel_device[:stream_specifier] hwaccel_device (input,per-stream) Select a device to use for ...
the document for extractMultipleFrames is not clear, since we add the folder to method extractMultipleFrames, why we need to add another path to save method? the folder is the place to save all frames, but specify it there doesn't work as expect, we have to extract frames when transcode...
Frames per Second When enabled, specifies the frame rate of the encoded video file. Format When enabled, specifies the format of the encoded video file. When disabled, the format is guessed from the file extension. Resolution When enabled, specifies the resolution of the encoded video file. ...
