Juliusz Chroboczek 00fbfafeeb Make unbounded channels explicit.

and webClient.  Make the structure explicit and testable.

Juliusz Chroboczek 1879ec81ea Don't send empty version fields.

Juliusz Chroboczek c501b76d2b Rework selection of simulcast tracks. 
We used to hard-wire the rid identifiers.  We now assume that
the simulcast streams are ordered in decreasing order of quality.
 2023-04-06 12:40:22 +02:00
Juliusz Chroboczek 4c9e00d874 Report username errors to client. 
We now report ErrUsernameRequired and ErrDuplicateUsername
errors by setting the "error" field of messages.
 2023-04-04 01:22:05 +02:00
Juliusz Chroboczek 8aa95f5e22 Add protocol messages for managing tokens. 2023-04-04 00:59:54 +02:00

Juliusz Chroboczek a1c1345719 Server-side support for protocol 2. 
The "time" field of messages is now a string in RFC 3339 format,
and there is a new "error" field in messages.
 2023-04-03 22:58:38 +02:00

Juliusz Chroboczek cc52e39ce4 Make some errors non-fatal. 
Don't disconnect the client for some more errors.
 2022-12-17 01:00:49 +01:00
Juliusz Chroboczek 8a2357de21 Only send chat history when joining. 
When we moved the chat history to the client goroutine back in 0.6,
we started sending the history whenever the group configuration changed.
Only send it when first joining the group.  Thanks to Rémi Nollet.
 2022-10-07 00:22:03 +02:00
Juliusz Chroboczek 0fe3ed2e15 Fix chathistory and display of anonymous users. 
Chathistory messages were formatted incorrectly.
We were also not formatting correctly messages from
anonymous users.
 2022-09-06 19:03:50 +02:00
Juliusz Chroboczek 3a2efbcc7e Send chathistory messages in the client goroutine. 
We used to send the chat history from the reader goroutine,
which would cause them to race with the join message.
 2022-09-06 03:03:50 +02:00
Juliusz Chroboczek 533e4b9b32 Version the protocol. 
The handshake message now contains a list of supported protocol
versions.  Version mismatch is currently a warning, but it will be a
hard error in the future.
 2022-09-02 14:30:51 +02:00

Juliusz Chroboczek 1b492114ad Fix typo in permissionsChangedAction. 2022-03-04 22:23:25 +01:00
Juliusz Chroboczek de3a016f4d Set the username in the server when using tokens. 
This avoids the need to pass the username in the URL without
requiring the client to parse tokens.
 2022-02-20 15:33:11 +01:00
Juliusz Chroboczek a86fb08f6c Replace ClientPermissions with a list of strings. 
Now that we support external auth, the permissions list is
open-ended.  Make it a list for simplicity.
 2022-02-19 23:44:57 +01:00
Juliusz Chroboczek 03811db37d Implement token authentication. 2022-02-18 13:35:17 +01:00
Juliusz Chroboczek 0ef5d10744 Display correct maxBitrate in statistics. 2022-02-01 15:20:43 +01:00
Juliusz Chroboczek 24187430e8 Rename client status to data, add group data. 
We now distinguish between status, which is maintained by the server,
and data, which is provided by the client.  In addition to client data,
we now support group data.
 2022-01-29 23:28:08 +01:00
Juliusz Chroboczek 710cc3cc14 Add ability to set initial user status. 
Setting the status after joining (using the "setstatus" action)
may cause multiple "user" messages to be sent to clients.  Add
the ability to set the initial status at join time.
 2022-01-28 22:21:19 +01:00
Juliusz Chroboczek e8fbfcb9ba Avoid overflow in bitrate computation. 2022-01-25 20:11:28 +01:00
Juliusz Chroboczek 39976d6d0d Protect webClient.actions with its own mutex. 
(*webClient).action may be called with the group mutex taken,
and therefore cannot take the client mutex.
 2021-12-11 01:33:47 +01:00
Juliusz Chroboczek abed33d654 Fix missing line break in subgroups command. 2021-11-29 17:33:46 +01:00

Juliusz Chroboczek 019f365981 Remove accessors for group description fields. 
Consult the description directly.
 2021-10-30 18:34:35 +02:00
Juliusz Chroboczek 869eb9b839 Move password checking into group.go. 
It used to be delegated to clients.
 2021-10-27 04:15:44 +02:00
Juliusz Chroboczek 09c5ba0d06 Protect against tracks without a stream. 2021-09-16 17:19:19 +02:00
Juliusz Chroboczek e81ee4af5e Remove userId and userName from rtpconn. 
They're redundant with the client field.
 2021-09-16 16:53:44 +02:00
Juliusz Chroboczek f683675ab4 Use a dedicated error value for anonymous users. 2021-09-09 22:26:08 +02:00
Juliusz Chroboczek 6aa7a9394a More tweaks to layer switching. 
I'm not seeing any non-keyframe spatial sync frames, so simplify
the code by only switching spatial layers on keyframes.
 2021-08-05 00:03:42 +02:00
Juliusz Chroboczek 9093339b62 Rework handling of buffered keyframes. 
Instead of buffering the last keyframe, we merely keep track of its
seqno, and use the main cache for recovering.  We also send the whole
sequence of packets rather than just the keyframe itself.
 2021-08-04 02:58:24 +02:00
Juliusz Chroboczek f4aa86a491 Switch spatial layers at the right point. 2021-08-03 23:21:44 +02:00
Juliusz Chroboczek 48a9b10ce8 Use spatial scalability when simulcast is not available. 
If the client requested a low-resolution stream and there is none,
switch to SID=0.
 2021-08-03 13:14:11 +02:00
Juliusz Chroboczek 4f7be19644 Implement pid and mark rewriting for VP9, fix VP9 sync bits. 
The sync bits were incorrect.  In addition, we need to set the
marker at the new end of the frame when doing spatial decimation.
 2021-08-03 13:09:43 +02:00
Juliusz Chroboczek 56226a2934 Export the max requested rate in track statistics. 2021-08-03 03:28:36 +02:00
Juliusz Chroboczek 200c0dd68c Refresh layer info after adjusting in down.Write. 
Otherwise we might act on outdated info, which could cause a spurious
drop.
 2021-08-03 03:15:08 +02:00
Juliusz Chroboczek 3d21a79880 Don't carry up tracks explicitly. 
Left over from the old data structure.
 2021-08-03 02:51:44 +02:00
Juliusz Chroboczek 51c31ab729 Improve error handling for negotiation failures. 
Now that we constrain tracks in offers properly, there is no need
to manually check that the codecs have been matched correctly.
