I wanna record a web page, and generate a video on server.
Here are my steps.
1. using puppeteer to screenshot the page one by one, and i have images;
2. using ffmpeg to generate a video from the images;
Q: I found that puppeteer launch more than one browser, screenshot will slow down. how to make puppeteer screenshot more effective? I use jpeg format, and reduce the quality to 80. If record a web page needs 30s, I make it chunk to reduce time, for example, launching more than one browser to cut down the recording to 2, or 3...
Try these packages:

Maybe you can reproduce or use it for videos production.
I am developing an android app, where I require to upload image/video files really quick. What could be the best approach to do the same? I am using windows azure media server.
I researched and went through the entire documentation on Azure yet couldn't find the right solution for the below problems. So, I am elaborating the list of issues and scenarios for your understanding.
Just to add top-up on this issue. Following are the scenarios.
We are uploading the video through app. - Need help is optimising the upload transfer rate by using viable compression.
As of now it is taking approximately 1-2 mins to complete the upload.
Post uploading the Video we crop the video using FFmpeg codecs in our application on VM and then move the video file to Blob Storage.
Followed by that we use the Azure Media SDK to make an asset to encode the cropped video for adaptive streaming and we also create the Progressive Download file for downloading the video which is cropped and has stiched images with it.
Cropped and Unstichhed video is played in the app which is of max length 32 seconds.
This still shows the buffering on the 4G network which is questionable?
Downloadable file which has images stiched with it comes out with noise in the bottom of the video. (Attached image for ref.) Ref. Image. Look at the right botton pixelation.
I have set up a wordpress theme called Video Board, the site I am building allows users to upload their videos for comments. Uploading a video from a mobile device is critical, the theme supports mp4 which covers android users, however it does not support .mov. Has anyone come across a way to play .mov in videojs?
The server has ffmpeg installed, however the last plugin I tried needed its own upload page which worked however videos were not captured in the themes latest uploads/popular posts etc.
I know a conversion would be the proper way to do it, but at this point I would even be happy working out a way that when users upload videos through the theme upload page, it doesn't actually convert but just changes the file extension(renames) it to .mp4, as that is all I have been doing to fill out some content.
I am open to all suggestions,
Thanks,
Sam
There are tech plugins for video.js, but these will require browser plugins. You're far better off converting the mov files after upload to standard formats, e.g. h264/acc MP4
I'm using flowplayer-3.2.18 plugin in a html file to play video files uploaded in my Media server. I'm trying to play a .FLV file in Flowplayer, file is loaded and played but with a black screen! Can anybody help to resolve the issue?
I faced same issue too and didn't find good solution.
But this is deffenetelly related to the video codecs. I changed my video codec for my video file and it works now.
Also you can try to check this video file using Wowza player and if it doesn't work too you can be sure that is something wrong with video file
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.
I finally found it. Apple has a good documentation of its own for this. https://developer.apple.com/library/mac/documentation/quicktime/conceptual/qtscripting_html/QTScripting_HTML_Document/ScriptingHTML.html#//apple_ref/doc/uid/TP40001525-2-GettingaBrowsertoLoadQuickTime
I simply had to use the embed tag properly as they have explained.
