1) CMTimeMake(1,10) actually means a value of 1 and a timescale of 10. They are a numerator and denominator, so it is 1/10 of a second, not 1 second. 2) The result will be like CMTimeMake(2, 10), which is 2/10ths of a second.
Technically ‘Yes’ (but not really…) HTML 5’s <video> tag is protocol agnostic—it does not care. You place the protocol in the src attribute as part of the URL. E.g.: <video src=”rtp://myserver.com/path/to/stream”> Your browser does not support the VIDEO tag and/or RTP streams. </video> or maybe <video src=”http://myserver.com:1935/path/to/stream/myPlaylist.m3u8″> Your browser does not support the VIDEO tag … Read more
I restarted this service : Host Network Service on windows Services program. And it worked. You can run these commands in the windows terminal instead, as @admin mentioned in comment section: net stop hns net start hns
ffprobe ffprobe -v error -select_streams v:0 -count_packets \ -show_entries stream=nb_read_packets -of csv=p=0 input.mp4 This actually counts packets instead of frames but it is much faster. Result should be the same. If you want to verify by counting frames change -count_packets to -count_frames and nb_read_packets to nb_read_frames. What the ffprobe options mean -v error This hides … Read more
Use the -ss option: ffmpeg -ss 01:23:45 -i input -frames:v 1 -q:v 2 output.jpg For JPEG output use -q:v to control output quality. Full range is a linear scale of 1-31 where a lower value results in a higher quality. 2-5 is a good range to try. The select filter provides an alternative method for … Read more
Codecs proper: ffmpeg -codecs Formats: ffmpeg -formats
I hated all these answers because they were too short or relied on other frameworks. Here is “one” vanilla JS way of doing this, working in Chrome, please test in other browsers: var video = document.getElementById(‘video’); var source = document.createElement(‘source’); source.setAttribute(‘src’, ‘http://techslides.com/demos/sample-videos/small.mp4’); source.setAttribute(‘type’, ‘video/mp4’); video.appendChild(source); video.play(); console.log({ src: source.getAttribute(‘src’), type: source.getAttribute(‘type’), }); setTimeout(function() { video.pause(); … Read more
Just put ?autoplay=1 in the url the video will autoload. So your url would be: http://www.youtube.com/embed/JW5meKfy3fY?autoplay=1. In case you wanna disable autoplay, just change from 1 to 0: ?autoplay=0.
According to RFC 4337 § 2, video/mp4 is indeed the correct Content-Type for MPEG-4 video. Generally, you can find official MIME definitions by searching for the file extension and “IETF” or “RFC”. The RFC (Request for Comments) articles published by the IETF (Internet Engineering Taskforce) define many Internet standards, including MIME types.
