video-conferencing

问题 It seems obvious that WebRTC uses its own rate control (GCC) to control the bitrate of the encoder, but I couldn't find any information about changing resolution as well. Does WebRTC, (or other realtime video system like Hangout, Skype) change only the bitrate and not the resolution during live ingest? If it doesn't change the resolution, why is that? According to the bitrate, quality, resolution curve shown below, using only single fixed resolution to cover bitrate changes seems not

问题 I have a server which is able to relay the WebRTC media data from A to B. For the video conferencing, if we go with P2P approach then a mesh network is created. Whenever P2P doesn't work, we can have this relay server. The main problem is that in the mesh network, the number of upload link is "N - 1" for N participants. Hence the number of connection goes upto N * (N-1). Usually mesh network allows 5-6 stable connections. Many online sources suggest to implement SFU. If SFU decrypts the media

问题 I am working on an application where I want to make a video call programmatically. I am using API level 8 for my application. I have Samsung Galaxy S, where I can use video calling functionality. Using intent action ACTION_CALL , I can start voice call. How to start video call? Which intent extra I have to provide? Is there any particular field which indicates that current outgoing call is video call? If yes, how can I set that field to indicate that I want to invoke a video call? 回答1: Here

问题 I would like someone's advice to find a solution for this situation. Basically what I need is to have a permanent web conference room in my web application to handle remote interviews. This means that any user of the web application can get access to the room and have an interview with another user of the same web application, I need only 2 connection at the same time. I did a little research about this topic and I have found several different solutions but none of them, at least at first

问题 This question is not only aimed at code but my app design as well. I have an iphone app that requires opentok to handle the video/audio sessions. I have gone through basic samples but what I am confused about is session management. For example, if my iphone app wants to call a user from a mapview, how do I do that if all I have is this user's location (coordinates)? How do I ensure that the session I am publishing gets to that particular user somehow and that user subscribes to it? Currently

问题 I've spent plenty of time solving this problem, but it looks like I need some help.
