Description At present, when downloading the list, the video formats can be selected as automatic, mp4, and webm. After downloading mp4, I use ffmpeg to view the downloaded videos, and the encoding format is vp9. This format may not have good playback support for some devices, and online preview may also have problems after uploading to the cloud storage. I hope to choose a specific encoding format, just like downloading a single video. I can choose avc1, vp9 encoding formats and different file suffixes mp4, mkv, and webm to meet different needs.
