阅读更多关于 Split, encode and join video parts in C#

问题 It is possible to split file into many parts.Is it possible every part encode and after that join them again? The idea is to encode one video on more computers.

There are also some libraries that are available to accomplish this. 回答2: Take a look at DirectShow .NET - it has some functionality for video capture and editing, although you still need to be familiar with general processing algorithms and methods.

Cannot play embedded videos on facebook wall unless SSL is disabled

阅读更多关于 Cannot play embedded videos on facebook wall unless SSL is disabled

问题 I am trying to embed (non-You Tube) videos on a Facebook wall so that when the user clicks on them, the video plays on the wall. What's happening is: if the user is not logged in or has SSL disabled, it works. However, if they access the page securely with an "https:" scheme or if they are logged in with SSL enabled, when they click on the video, a new tab is launched with the address of the page where the video resides. I have researched this problem. The two solutions I have are, updating

问题 I have IP camera and I don't know it's full correct url address to RTSP stream. There is port only in RTSP settings but 192.168.1.132:554 is not enough as I understood.

阅读更多关于 HTML5 Video - Suspend Loading / Partial Load

问题 Is there a way to preload a portion of a video, but not the entire thing? I noticed that there is a "suspend" event that indicates the video is expectedly not downloading until further instruction, but I'm unsure of how to trigger this event? My goal is to preload a portion of a video without taking up all the users' bandwidth. Thanks! 回答1: You can pre-fetch any URL with XHR, but you can't control how much it pre-fetch from the client-side. I think you can try this: set a header in the XHR

阅读更多关于 Google Tag Manager & Youtube Conflict

EDIT: the problem is no longer relevant. GTM do not affect Youtube API anymore. (In the jsFiddle demo, video informations (state, currentTime, duration) are always correct). Calling the Google Tag Manager seems to wreck the Youtube API. Here is a fiddle demo : Google Tag Manager & Youtube (jsfiddle) // where thoses methods do not work anymore player.getPlayerState(); player.getCurrentTime(); player.getDuration(); by commenting the line 16 Youtube API works again (correct state, correct currentTime / duration displayed). Since the video is still playing, it seems like the js api is disabled.

问题 I am interested in developing an application that will allow me to build a list of videos from xml (containing video title, duration, etc) and play that list as my webcam stream. Meaning, if I were to visit ustream.tv, or activate my webcam on live messenger my video playlist would register as my active webcam.

问题 I am trying to build mobile app which can stream video from both sides(i.e something like video calling). I looked into webrtc, but thats not yet ready for mobile native apps as such and anyways what webrtc was doing was allowing browser to capture camera and audio directly without requiring plugins etc. But in native mobile apps capturing camera and audio isn't a issue and basically a very low latency and dual transport layer is needed. In many articles and places I read about using webrtc
