Currently, FLV tools provided on the Internet include flv2jpg ProgramAnd use FFMPEG. However, FFmpeg is affected by the limited encoding supported by FFMPEG, And because FFmpeg is not implemented in DirectShow mode, therefore, you cannot use various DirectShow decoder filters installed on the local machine. Therefore, many videos may fail. Swishzone.com provides a FLV source filter. With this filter, We can smoothly load the FLV file and mount the decoder installed in various systems to facilitate operations. The grabbitmaps example provided by Microsoft DirectShow can be used to perform any video operations. I have made improvements on the basis of grabbitmaps. You can specify the size of the target image and save the image in JPG format. In addition, you can automatically select relatively ideal video frames.
