问题 This question was migrated from Video Production Stack Exchange because it can be answered on Stack Overflow. Migrated 5 years ago . I have video that will be divided into 4 videos. First the player will stream a lower resolution of the original video, then the user can zoom into the video to see more details, I need the player to stream one of the 4 videos - that's higher in resolution- based on where the user zoomed in. How can I make that using VideoJS or any other video player ? 回答1:

MP4 to DASH (bash script)

由 和自甴很熟 提交于 2019-12-12 09:58:37
问题 I have a web site in which users can upload video files. I want to stream all of them using DASH to obtain an adaptive bitrate streaming. So I wrote a bash script (to run by cron) that converts all mp4 files to DASH, but it doesn't work properly: what is wrong? For example, using the following script, I obtained: https://www.informatica-libera.net/dash_faq/stream.mpd It validates, but it doesn't play. I tested it on: http://dash-mse-test.appspot.com/dash-player.html?url=https%3A%2F%2Fwww

问题 for this stream: is there a class that can capture the stream for manipulation? all i found was tutorials about how to make client server, or read from computer connected cam. Update: it looks promising. trying to open this again failed , so i followed the asx which said: <asx version="3.0"> <!-- GMEmbed --> <title>CastUP: Ayalon</title> <entryref href="http://switch3.castup.net/cunet/gm.asp?format=wm&s=4A59334AD43141A7BFD73D7CE6B71560&ci=15369&ak=35143679&ClipMediaID=21329&authi=&autht=&dr="

由 余生长醉 提交于 2019-12-12 05:35:36
问题 I'd like to start of by apologizing for this ridiculously long post, but I tried to provide as much code and data as possible for you to refer to. I am working on a video project where I will need the flexibility of the AVQueuePlayer (foremost the ability to scale and layout the video layer freely, as well as creating my customized controls). Problem is, I need to be able to mix video content of different types (in this case progressive download .mp4 and http streaming .m3u8). Here's where

How to buffer stream when the video is paused with flash

由 跟風遠走 提交于 2019-12-12 03:44:59
问题 I need a feature of allowing buffering the video when it's paused, which I cannot find how to do it directly... I notice that, when I pause the video, the event "NetStream.Buffer.Flush" is triggered. And according to the language reference: "Data has finished streaming, and the remaining buffer will be emptied.", I have to re-buffer it, right? However, also according to the reference, it shouldn't stop buffering: Starting with Flash Player 9.0.115.0, Flash Player no longer clears the buffer

Writing alpha channel into decoded ffmpeg frame

由 跟風遠走 提交于 2019-12-12 03:38:43
问题 I am looking for a fast way to add my own alpha channel to a decoded ffmpeg frame. I have an AVI file with RGB information, and I have a synchronized video stream describing the transparency alpha channel (grayscale). While decoding the AVI file using ffmpeg, I want to convert the output frame to RGBA, while adding my own alpha information. In the end, I would obtain a semi-transparent video stream. Is there any optimized function, maybe in libswscale or libswresample, to do such a thing
