There are two major challenges. The first is a technical one. 80x60 pixels is not much. It is enough to see a face clearly, if the face is the only thing in the picture. However, most people have their cameras placed so that 70% of the picture area is the room they are sitting in. That will not give a good enouh picture. So, we'll need a method to extract what we need from the image.
* Protocol Buffer based network protocol. Start merging everything into the PlayerState, ChannelState etc packets. The server should wipe fields it doesn't know about.
 
* Drop packet type etc from UDP, make it use it's own protocol, and have "TCP mode" be a "UDP tunnel packet" message.
 
* CELT-48k.
 
* Comments
 
* Associative key-based storage DB.
 
* Allow third-party "key/value" stored.
 
* Add a "context" for plugins, being a 32-byte array or somesuch. Players need identical context to get positional audio of each other.
 
* Add a "identity" for plugins, to be transmitted to the server.
 
* Multichannel echo cancellation.
 
* G15 for OSX.
 
* Client-certificate based authentication.
 
* Friends list -- recognize your friends (works across servers).
 
* s/Player/User/
 
* Switch to TCP mode if no ping packets work within the first 20 seconds, and switch back if it gets fixed.
 
* Add additional datafields to the banlist editor
 
* Make address be 2 x quint64 instead of 16 x char, and make it be hashable etc.
 
* Automatic plugin updates.
 
* User unregistration
 
* more formats for event sounds
 
* VoiceTarget message, use those 5 bits of the UDP type to differentiate Speech, AltSpeak and <target at specific user/channel>-speak.
 
* Upload textures from the client.
 
* If selfgen cert, and meta has a proper cert for the same host, use meta's instead.
 
* Give logical names to everything in the UI. Skinners currently use names like "groupBox_2", which is a bit error prone when we change the gui.
 
* QDesktopServices::storageLocation to replace getenv etc?
 
* OnlyAcceptWhispersFromFriends
 
* Multibind support for murmur, and IPv6.
 
* Per-server config storage for whisper targets.
 
* Fix ASIO.
 
* Try adding a 11x binary alongside the 1.2.0.
 
* Presets (import config)
 
* Access Tokens (aka password-protected channels)
 
* Temporary channels

The second is bandwidth. Yes, the video stream will use less bandwidth that an audio stream, but it will be going the whole time. This means that while audio bandwidth scales linearly with the number of users, video bandwidth scales exponentially. For example, if we assume that each user has 30 kbit/s of audio and 20 kbit/s of video. When one user talks, the others shut up. With 10 users, that's 9*30=270 kbit/s out from the server. Video, which is going the entire time, is 9*20=180kbit/s ''for each user'', giving us a total of 1.8Mbit/s.

The current overlay texture system is designed for high speed texture transfers in a format that happens to be 60 pixels high. This is no coincidence.

Using H.264 encoding, 80x60 pixels is small enough that we can encode a 15fps video stream with minimal CPU impact. The bitrate will also be low (lower than existing audio streams), and with a bit of filtering the quality is near perfect. I really mean this; what filtering did for the audio quality in Mumble it also does for video quality.

I'd like to see this happen; I miss seeing my friends when we're gaming. It's one thing to hear enthusiasm, it's quite another to see it.

There are two major challenges. The first is a technical one. 80x60 pixels is not much. It is enough to see a face clearly, if the face is the only thing in the picture. However, most people have their cameras placed so that 70% of the picture area is the room they are sitting in. That will not give a good enouh picture. So, we'll need a method to extract what we need from the image.

The second is bandwidth. Yes, the video stream will use less bandwidth that an audio stream, but it will be going the whole time. This means that while audio bandwidth scales linearly with the number of users, video bandwidth scales exponentially. For example, if we assume that each user has 30 kbit/s of audio and 20 kbit/s of video. When one user talks, the others shut up. With 10 users, that's 9*30=270 kbit/s out from the server. Video, which is going the entire time, is 9*20=180kbit/s for each user, giving us a total of 1.8Mbit/s. For all clans and guilds who host their servers somewhere with free bandwidth, this is not a problem. However, I don't really want to know what a 2mbit/s commercial hosting is going to cost. I doubt it's cheap.

Some suggestions have been brought up by the community:

  • Using WebM instead of H.264. When the time comes, we will look into it. VP8/WebM has the advantage of better licensing. H.264 with its free encoder x264 has the advantage of longer history and (thus) performance. We are aware WebM is improving in the performance field as well though.1
  • Instead of continuous transmission, only transmit video when the user talks – as an optional feature.1
