Juliusz Chroboczek 0ec9f92dad Make 'clearchat' into a user message. 2021-01-03 17:47:56 +01:00
Juliusz Chroboczek e393819eda Carry raw SDP in the protocol. 2021-01-03 17:00:58 +01:00
Juliusz Chroboczek f53276b89e Simplify the protocol and the protocol interface. 
Split the id field into id and source, where source indicates the sender
of the message and id the entity being sent.  Remove the label request,
just use the offerer's username.  Maintain the username within the
ServerConnection, this removes a parameter from some methods.

Juliusz Chroboczek 450601f0e8 Move ICE code into own module, add tests. 2021-01-02 00:21:17 +01:00

Juliusz Chroboczek a0418d26ec Send RTC configuration with joined message. 
This avoids one HTTP request, and is potentially more flexible.
 2020-12-28 02:55:19 +01:00
Juliusz Chroboczek d09c0f0a80 Make the value field of client messages carry arbitrary types. 2020-12-28 01:49:27 +01:00
Juliusz Chroboczek 9e4aede72a Fix issues with unaligned atomic operations. 
This could be solved by simply reordering the fields, but it
is more robust to move the atomics into their own structure,
and the extra indirection should not cost much.
 2020-12-27 01:31:31 +01:00
Juliusz Chroboczek e88942c9a9 Reduce the NACK delay. 
We bound the NACK delay to 2 packets, which is what TCP does.
Thus, reducing the delay should be safe.
 2020-12-26 22:09:26 +01:00
Juliusz Chroboczek 5d38b0a231 Allow various codecs. 
It is now possible to specify codecs other than VP8 and Opus.  This
turns out not to be very useful, since VP8 is the only codec supported
by all browsers (in violation of the WebRTC spec, which mandates support
for H.264), and there is no good reason to use anything other than Opus
for audio.
 2020-12-26 19:46:37 +01:00
Juliusz Chroboczek 2785fa9f77 Store labels early. 
This avoids spurious up.complete indications.
 2020-12-25 22:32:30 +01:00
Juliusz Chroboczek f4379f7a8c Protect against negotiation inconsistencies. 
This is not an issue in the current code, assuming that clients
negotiate correctly, but will become one once we implement codec
flexibility.
 2020-12-25 20:50:33 +01:00
Juliusz Chroboczek 3c04d48b85 Push a connection even if all tracks didn't arrive. 
We used to push a connection when we got all tracks.  However, it may
happen that some tracks fail; in that case, the connection would never
get pushed.
 2020-12-25 20:23:46 +01:00

Juliusz Chroboczek a2f5bb82d1 Delete unrequested connections in addDownConnTracks. 
We don't renegotiate down connections yet, but this is a latent bug.
 2020-12-18 18:56:07 +01:00

Juliusz Chroboczek 0e7bf0b348 Carry group around when pushing connections.

are pushed.
 2020-12-05 00:07:34 +01:00
Juliusz Chroboczek b134bfcf13 Improve error handling on join failure.

They now have the same format as chat messages; the only difference
is that they are not stored in the chat history.

Also adds userMessage method to ServerConnection.

Fix usermessages.
 2020-11-30 14:39:36 +01:00

Juliusz Chroboczek 7ee8cbc45a Don't push incomplete connections. 
If a connetion is slow to get established, this would cause it to
be pushed twice, the first time before it is complete.  Thanks to
Roman Koval who noticed the issue.
 2020-11-05 20:48:07 +01:00

Juliusz Chroboczek c8de6620a7 Send non-trivial bitmaps during NACK forwarding. 2020-10-12 16:18:57 +02:00
Juliusz Chroboczek 5e130122f5 Forward NACKs to sender in case of double loss. 
We already send NACKs when a packet is missing.  Under high packet loss,
however, the recovery packet might get lost two.  Forward receiver NACKs
to the sender, but only after a delay and after checking that the packet
has not arrived in the meantime.
 2020-10-12 13:00:59 +02:00

Juliusz Chroboczek 4a8e48d146 Take next packet index into account when sending NACKs. 
This avoids sending NACKs for packets in the future.
 2020-10-04 16:07:23 +02:00
Juliusz Chroboczek 67a821ea75 Increase minimum size of packet cache.
