We can't reproduce such error in latest WCS build 5.2.1443. Please update and check. If the issue still reproducing, collect a report: Getting logs with report.sh script then send the report and your offline_mixer.json config file using this form.

Архив нужно скачивать и распаковывать в директорию tmp или другую, отличную от /usr/local В процессе установки должен создаться symlink /usr/local/FlashphonerWebCallServer --> /usr/local/FlashphonerWebCallServer-5.2.1440 указывающий на директорию с номером версии.

Здравствуйте. При активации записывается файл /usr/local/FlashphonerWebCallServer/conf/flashphoner.license Убедитесь что директория /usr/local/FlashphonerWebCallServer существует. Если не существует, то возможно установка не была произведена или прошла некорректно. Для корректной установки...

Good day. You can use canvas streaming, but there are some issues in this case: 1. The browser tab where canvas element is placed, must be in foreground, otherwise there will be freezes: browser stops sending media traffic when the page goes to background. 2. The stream picture size is limited...

The mixer_video_threads sets how much threads WCS will use to encode video in mixer output stream. This value is 4 by default, and should not be less because encoder may fail to process all incoming data. Usually, 4 threads is enough for most cases unless you're feeding the mixer with a huge...

This is not an error. The message means mixer native code cannot encode the frame for some reason. In this case, the frame is dropped. Usually, this may be due to packet loss or frame corruption. You can try a strict jitter buffer to reduce this use_strict_jitter_buffer=true...

Добрый день. Проблема с переключением в полноэкранный режим в Safari 16 исправлена в сборке Web SDK 2.0.224. Чтобы переключение в полный экран и обратно работало, необходимо включить стандартные элементы управления в плеере. Также был изменен код Embed Player.

Good day. Please try to reproduce it with the default full screen desktop layout mixer_video_desktop_fullscreen=true and with the sample custom full screen layout. If the flickering is not reproduced, seems like this is your custom layout implementation issue, so review the code.

Good day. Seems like Firefox still can't publish a stream with aspect ratio 1:1, it even ignores aspectRatio: 1 constraint. So use Chrome to publish a square stream.

Yes, the clientBrowserVersion is used to detect a browser and then use a proper DTLS. That's because WCS initiates DTLS handshake, not browser (WCS sends Client hello), threfore the only way to predict a DTLS version supported is browser version. So you should keep this field untouch in backend...

Good day. Since build 5.2.1440, MKV container is supported for multiple stream recording. Please see details here: Multiple stream recording to one file with subsequent mixing

Good day. Seems like in failure case WCS waits for certificate chain from publisher, but does not receive it (missing a Server Hello packet). Please try to switch to TCP transport to prevent a packets loss. You can also collect a traffic dump and check if DTLS flow is correct: DTLS traffic

Добрый день. Пока что эта функция в iOS SDK не поддерживается. Создали тикет WCS-3614, отпишем по прогрессу.

Try to enable Multithreaded encoding while mixing multiple stream recordings by adding to /usr/local/FlashphonerWebCallServer/conf/offline_mixer.json file the following parameter: "multithreading": true This should make encoding a twice faster.

Good day. That's the bottleneck. One mixer requires 2 CPU cores (with default settings), so you should use at least 8 CPU / 16 Gb RAM.

VP8 codec is supported by all the modern browsers and OSes, so it can be played without transcoding. But you will need VP8 to H264 transcoding if you're republishing VP8 stream to a third party RTMP server or playing the stream as RTMP from WCS (because RTMP supports only H264) or if you're...

We raised the ticket WCS-3613 to investigate the issue. But it may take a time, we'll inform you about progress. A possible workarounds: 1. Do not use 320x240 resolution in Firefox (for example, use 320x180 if it works) 2. Or use VP8 codec You can also try to enable a strict jitter buffer to...

Received the dump, waiting for your feedback about the settings.

You can reduce websocket unanswered pings count: keep_alive.probes=1 In this case, WCS should detect a network disconnection after 10 seconds. note that it can get a false positive on unstable networks.

We checked the report. Unfortunately, it contains no traffic dump, so we can't reproduce the issue on our test servers, we only can to analyze the logs. Seems like Firefox does not send key frames while publishing 320x240. Please enable periodic key frame request in server settings...
