Good day. WCS 5.3 may be installed over WCS 5.2: New version installation with previous version update WebSDK build 2.0.259 should work with both WCS major versions. Please note that Java 8 is not supported any more in WCS 5.3, you shound install JDK 21 first: JDK installation At lease two...

We checked the report. The thread serving secure websocket connections consumes 100% CPU. Please add the configuration file thread_pools_config.json to the /usr/local/FlashphonerWebCallServer/conf folder with the following content { "ws_SERVER": { "nio": false } } This switches...

Hello Please send a report via the private form Make sure the report contains the latest CemeteryDump.jstack files. If they are missing, please attach them manually as a separate tar archive. CPU troubleshooting: 1. Install htop using your package manager. For RedHat/CentOS use: yum install...

Добрый день. К сожалению, мы не вносим изменений в код WebRTC библиотеки. Создали тикет WCS-4556, в его рамках проверим, получится ли пересобрать ее согласно требованиям Google. Возможно, что и не получится, поскольку ограничения - это часть стратегии по переводу потребителей на новые...

Good day. Please update to the latest build 5.2.2294. If the stream still not playing after update, please provide a public RTSP URL using this form, our engineeers will check it.

Perhaps a newer WCS builds requires non-empty REST hook response, but older builds may be not so strict.

We checked the server. There are the following problems in configuration: 1. Non-critical: there are no such parameters anymore in flashphoner.properties like sip_enabled=true rtp_force_synchronization=true Please remove them 2. Critical: seems like your SIP PBX does not respond to REGISTER...

Good day. Please make sure you've done a clean WCS installation, not directly update from 5.0 or earlier versions. Also please make sure you do not unpack an installation archive directly to /usr/local folder. If this recommendations do not help, please provide SSH access to the server using...

Please be careful: Docker is easy to deploy but it's very hard to debug WebRTC in Docker in production under high load. Read this article for example: How to use Docker with WebRTC in production

Good day. The official Docker image is updated: - Ubuntu 24.04 - OpenJDK 21.0.2 - WCS 5.3 Please read the updated docs: WCS in Docker

Good day. We cannot reproduce the issue with build 5.2.2292. Please reproduce at your environment, collect a report as described and send using this form.

Good day. The following parameter mp4_container_write_header_on_fly=true may help. In this case, MP4 header and MP4 data will be written to a separate files then concatenated when recording is finished (by stream stopping or by REST API query). This would be much faster. The record hook...

Добрый день Эти две проблемы связаны с периодичностью поступления ключевых фреймов от RTSP камеры. Если есть такая возможность, рекомендуем выставить на стороне камеры отправку ключевого фрейма каждые 2 секунды (если, например, у камеры есть опция keyframe interval наподобие OBS). Если такой...

Good day. We checked the report sent via e-mail. There are no any issues in the server logs: the RTSP stream is captured successfully, then (after 40 seconds) the client stops stream playback There is no the client log in the report. Also, there are no SDR logs. Next time please collect a full...

Для WebSDK на стороне клиентского кода можно реализовать автоматическое переподключение зрителя: Автоматическое восстановление воспроизведения потока, Streaming Auto Restore В этом случае заглушку с отображением статуса реконнекта необходимо также отрисовать на клиенте.

Здравствуйте Под "Стрим не прерывался" мы понимаем следующее поведение: 1. User1 заблокировал экран устройства, устройство закрыло соединение с сервером. 2. В это время, зрители продолжают видеть черный экран заглушки. 3. Зрители дожидаются когда User1 восстановит стрим, без отключения. 4...

Добрый день. Нет, это неверно. Когда какой-либо сервер в CDN запускается, ему нужна точка входа: адрес узла, с которым сигналинговое соединение будет установлено первым. После того, как это соединение установлено, узел получает описание текущего стейта CDN со списком всех активных узлов, и...

Good day. Since build 5.2.2269 we've added the userAgent parameter to identify any browser which is needed to be fixed. Please update and add the following parameter to flashphoner.properties quick_fixes={"WCS4432":{"userAgent":"(Mozilla/5[.]0 \\\\((iPhone|iPad|iPod);.*OS...

The server audio processing may be applied to streaming only, not to SIP calls. WCS is just a SIP gateway, not a PBX, so it may redirect media streams from browser to SIP PBX and vice versa. We recommend to process SIP audio at SIP PBX side (Asterisk, OpenSIPS etc).

Good day. You can add a custom Java class to intercept a decoded audio frames at server side: Server audio processing. Note that this feature requires audio transcoding to be enabled on the server, that increases the server CPU load in its turn.
