html5-video

问题 I am a newbie in video streaming and I just build a sample website which plays videos. Here i just give the video file location to the video tag in html5.

问题 We have some files encoded in AV1, but we recently noticed that Chrome mobile fails to play the files - but it doesn't fall back to an encoding it can use - it just puts the unplayable AV1 file in there. I'm hoping that if we add a codec attribute we can remedy this - but I'm not sure how to determine the codec for these AV1 files. I've come across this documentation on MDN, but I'm not sure how I would determine the proper codec from that. It starts off simple enough, but some of the values

问题 Is there any existing plugin to change the playback rate of a video using the video.js player? If not, how can I add the new plugin and the new control button for the same? Thanks in advance. 回答1: I've the same issue. I just found that: videojs('my-player', { playbackRates: [0.5, 1, 1.5, 2] }); see videojs docs 回答2: From videojs v.4.6.0 on there is a JSON parameter for data-setup that you can pass to add the playback speed option to the videoplayer: <video id="my_video_1" class="video-js vjs

问题 I have tried using iframe and also video tag and object tag to play the video. In some cases, it plays only the audio from the video, but video doesn't show up. Secondly, the same video file plays well on a separate tab in the browser, but not within my iframe. This issue is on all browsers on my Mac, but on a windows machine it plays well. 回答1: I finally found it. Apple has a good documentation of its own for this. https://developer.apple.com/library/mac/documentation/quicktime/conceptual
