HTML5 generating video from images

北慕城南 提交于 2019-12-03 06:25:24
问题 i'm wondering, since HTML and with javascript are mesmerizing together, if there is a solution in HTML5 to generate a video-file from many images? For example, you're able to load a video into a canvas and make it appear as greyscaled video, by manipulating the canvas. However, I would like to know, if there is somewhat a method to generate a video-file out of that greyscaled version. Would make sense, if you want to send the video via whatsapp etc. Thank you 回答1: There are currently no built

I run my webrtc code with chrome 21. If I open two tabs in the same chrome, and then open page with webrtc code inside.

However, If I open page with two Incognito mode or two different chrome browser, I can get the sdp and candidate information correctly. It seems that video can decode the information.

In YouTube, we can change the quality of the video from a dropdown like 360p, 144p, 240p, etc. Can we do the same with HTML5 video element from JavaScript?

HTML5 Video Not Displaying on iPad

北战南征 提交于 2019-12-03 06:08:23
I've encoded a few videos on http://www.theparkerpalmsprings.com to play using HTML5 when loaded via an iPhone or iPad. In my testing, everything works as expected when viewing the site on an iPhone (I've tested on a 3G and iPhone 4), but when loading on the iPad the Quicktime logo flashes quickly and then nothing happens. Is this a problem with the encoding of the videos or am I doing something else incorrectly? Any input would be greatly appreciated! A few test links (directly to pages with video): http://theparkerpalmsprings.com/spa/ (large video on iPad, small video on iPhone) http:/

HTML5 Video: Streaming Video with Blob URLs

廉价感情. 提交于 2019-12-03 06:06:56
问题 I have an array of Blobs (binary data, really -- I can express it however is most efficient. I'm using Blobs for now but maybe a Uint8Array or something would be better). Each Blob contains 1 second of audio/video data. Every second a new Blob is generated and appended to my array. So the code roughly looks like so: var arrayOfBlobs = []; setInterval(function() { arrayOfBlobs.append(nextChunk()); }, 1000); My goal is to stream this audio/video data to an HTML5 element. I know that a Blob URL

余生颓废 提交于 2019-12-03 05:52:33
I have a video file in MKV format, i want to play that file in the browser without converting, how can i play this file format in browser? <video width="320" height="240" controls> <source src="movie.mkv" type="video/mkv"> Your browser does not support the video tag. </video> i want this file to be played in full screen mode always. My browser is chrome. It will refuse to play Matroska if the type attribute is set to video/x-matroska . Try removing the type attribute completely. After some experimentation with this issue, I've found the best solution is to set the mime type to video/webm .

Playing MP4 files in Firefox using HTML5 video

I have searched around quite a bit but have not solved my problem. I have a video tag running as follows: <video class="ne" src="{{ page | video_url }}" muted="true" volume="0" controls width="720" height="480" poster="{{ page | video_poster_image_url }}" type="video/mp4"> </video> I am using Jekyll for the URLs. They work fine. The site is live at switzerlandllc.com . Click any video in FF and it shows an image and an X. Chrome and other browsers work fine. If you grab the source of a video and load it in a new tab it plays fine. At least it does for me. I have added: AddType video/ogg .ogv

RTSP h.264 in google chrome browser

淺唱寂寞╮ 提交于 2019-12-03 05:32:56
After we are moving over to html5 and many browsers like Google chrome bans VLC web plugin. ... Is there any way to play h.264 / h.265 Rtsp streams in browsers this days ? Direct RTSP streaming is still not supported by browsers, if you have to play an RTSP stream in the browser then you need a proxy server that will convert RTSP to HTTP stream. Many open source projects are there that will do the work of RTSP to HTTP conversion or you can use FFmpeg (used by VLC) to convert RTSP to HTTP and then can stream it on the browser. These guys put together an rtsp over websocket player. https:/

Current best practice to stream live video in web browser?

荒凉一梦 提交于 2019-12-03 05:15:46
问题 We develop an IP camera product which streams H.264/MPEG4/MJPEG video via RTSP/UDP. It has a web interface, currently we use the VLC Firefox plugin to allow viewing of the live RTSP stream in the browser but Firefox are dropping support for NPAPI plugins so that's currently a dead end. The camera itself is a relatively low-powered ARM SoC (think Raspberry Pi level) so we don't have vast spare resource to do things like transcode streams on-the-fly on the board. The main purpose is to check

问题 How do I grab a snapshot of a video file selected via <input type="file"> at a specific time in the video silently in-the-background (i.e. no visible elements, flickering, sound, etc.)? 回答1: There are four major steps: Create <canvas> and <video> elements. Load the src of the video file generated by URL.createObjectURL into the <video> element and wait for it to load by listening for specific events being fired . Set the time of the video to the point where you want to take a snapshot and
