Good day. We fixed the issue with keyframe detection in build 5.2.1460. Now, H264 320x240 stream published from Firefox on NVIDIA GPU should play correctly. Please note that in the dump you provided there is only one keyframe in the beginning of the stream, so it may not play for subscribes who...

Добрый день. Проверьте, работает ли публикация потока только с аудио в Chrome в примере Media Devices: Убедитесь, что в статистике слева отображается число отправленных пакетов, проиграйте этот же поток в том же примере с сервера. Если поток играет, убедитесь, что Вы указали правильные...

Good day. The latest public WCS build is 5.2.1452, not 1453. Please check if Conference example works with a default application http://localhost:8081/apps/RoomApp. If yes, you did not probably pass any REST hooks from your custom application to default RoomApp. This must be done because a...

Good day. Please check if RTSP source is available from inside the container (ping the source IP, try to connect to the source using static ffmpeg build).

Проверили Ваш сервер. Действительно, лицензия была ранее активирована на другом сервере, который, возможно, был удален без деактивации. В этом случае лицензия типа Standalone блокируется. Сейчас лицензия разблокирована, можете ее активировать. Обратите внимание: если будете мигрировать этот...

Good day. Please ensure you've set the following parameters in flashphoner.properties rtmp_transponder_full_url=true rtmp_transponder_stream_name_prefix= rtmp_flash_ver_subscriber=LNX 76.219.189.0 rtmp_transponder_send_metadata=true Also please check if you can stream to Youtube from OBS...

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.
