问题 I have a mp4 video to automatically play on website, but it doesn't play on iphone. Referring to other Q & A about the same issue, I added "playsinline" to the video tag. However it doesn't seem to work and nothing is displayed on the screen of my iphone. Could anyone help me find out what is wrong with my code? <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie

Video banner in html (bootstrap page) incorrectly laid out

由 ﹥＞﹥吖頭↗ 提交于 2021-01-28 11:30:34
问题 I am attempting to adapt code from this site: Video Header snippet This places a video header and it overrides my entire page and content with itself (the video header). I would like to resize the header so that it has a width of 100% (across the whole page) and a height of x (decided by me) e.g. 200. I've tried various things to change both the overlay size and the video but nothing has worked. <h1>My Website</h1> <p>Website text here</p> <header> <div class="overlay"></div> <video

Get titles from playlist videos in YouTube iframe API (javascript)

由 橙三吉。 提交于 2021-01-28 06:10:30
问题 I know that you can usually get current video titles using: player.getVideoData().title; But I was wondering if there is a way to get the titles from the playlist rather than just the current video and WITHOUT using the YouTube Data API? There is: player.getPlaylist(); But it only returns an array of video IDs. Is this even possible, or must I go through the YouTube Data API? 来源： https://stackoverflow.com/questions/44979372/get-titles-from-playlist-videos-in-youtube-iframe-api-javascript

How do I split a video to 2 separate files for odd and even fields using ffmpeg?

由 旧街凉风 提交于 2021-01-28 02:41:46
问题 I have a h.264 progressive 640x480 video. I'm trying to create 2 separate video files, each is 640x240 and consisting only the odd fields and even fields seperately. Firstly I converted the file to interlaced but now I need to convert to 2 files. How do I do that based on yuv format? Once I'm done, I will encode the files separately and then rejoin them to a single interlaced file. How do I do that? 回答1: Starting with the full progressive video, you can do it in one step. ffmpeg -i in.mp4
