The video must be loaded and at the frame you want to

问题 I want to be able to play back video from a specific time using the HTML5 video tag (and currently only need to worry about Chrome). This is possible by setting the currentTime property of a video element. That works fine in Chrome with a video sourced from html5rocks.com, but is ignored when the same file is loaded from my own local webserver. Using the sample code from http://playground.html5rocks.com/#video_tag, I have arrived at the following HTML: <!DOCTYPE html> <html> <body> <video id=

Conversion from mjpeg to mp4 (libx264) with FFmpeg

由 那年仲夏 提交于 2021-01-29 10:56:57
问题 If you convert from mjpeg to mp4 (libx264) with FFmpeg, Playback can not be performed on Windows · Mac. Thumbnails are not displayed on the icon. However, with the HTML5 Video tag, playback is possible. Why? Please tell me if you understand. Thank you. ffmpeg -i source_file.mov -b 4000k -vcodec libx264 destination_file.mp4 回答1: The usual reason for this is the pixel format. The MJPEG may have 4:2:2 or 4:4:4 chroma sampling which most players don't support in H264. So try ffmpeg -i source_file
