إعادة البث وتحويل الترميز

Take one live or continuous source to a destination, with optional protocol conversion, transcoding, audio selection and image overlay.

ما الذي تفعله هذه الوحدة

A Restream job owns one source-to-destination path. Create one job per destination so a platform error, credential change or output profile can be isolated without disturbing the other outputs.

قبل البدء

  • A source that plays correctly before it enters the Restream job.

  • A destination URL/key or supported destination account.

  • A tested output codec, resolution and bitrate when transcoding is required.

شرح الإعدادات

نشرح عناصر التحكم التي يحتاجها المشغّل فقط، ولا نعرض أسماء الحقول الداخلية أو أحداث التنفيذ.

Input

Choose one verified media source.

Input source

Select an SRT, RTMP, NDI, WebRTC/conference, file or supported URL source.

Source-specific connection

Provide the server, stream identity, participant or URL required by that input type.

Output

Choose one destination for this job.

Destination type

Supported social platform, RTMP/SRT/HTTP/RTSP/UDP endpoint, NDI output or conference participant.

Destination URL and key

Credentials and address supplied by the receiving platform.

Media processing

Enable only processing that the destination actually needs.

Video profile

Codec, resolution, frame rate and bitrate for a transcoded output.

Audio track and channels

Choose the required source audio and output layout.

Image overlay

Place a prepared graphic over the outgoing video.

Pass through

Avoid re-encoding when source and destination requirements already match.

أول مسار آمن

  1. 01

    Verify the source independently.

  2. 02

    Create one Restream job and select the source preset.

  3. 03

    Choose one destination and enter its exact URL/key.

  4. 04

    Keep pass-through when compatible; otherwise select a tested transcoding/audio profile.

  5. 05

    Start the job and verify its statistics plus playback at the destination.

كيفية بنائه

  1. 1

    Create one Restream job for the first destination and verify it end to end.

  2. 2

    Duplicate the workflow as a separate job for each additional destination.

  3. 3

    Use destination-specific credentials and output settings.

  4. 4

    Monitor and restart only the destination that reports a failure.

كيفية بنائه

  1. 1

    Upload and preview the file in File manager.

  2. 2

    Use the file as the Restream input and configure continuous playback.

  3. 3

    Choose the output protocol and transcode only if the endpoint requires it.

  4. 4

    Start the job and validate the transition from the end of the asset back to the beginning.

كيفية بنائه

  1. 1

    Create the video room and verify the participant in the browser.

  2. 2

    Select that participant as the supported input preset.

  3. 3

    Create the NDI output with a production-friendly name.

  4. 4

    Discover and monitor the output on the receiving NDI system.

تحقق من النتيجة

  • The source is healthy before the job starts.
  • Restream statistics show active media and the destination confirms ingest.
  • Output codec, resolution, audio and overlay match the receiving requirement.
  • A failed destination can be stopped or restarted without stopping other jobs.

استكشاف الأخطاء

The job is active but the platform is offline

تحقق
  • Check the destination URL/key and platform event state.
  • Confirm output bitrate.
  • Verify codec compatibility.
ثم نفّذ

Repair the destination or output profile while leaving the verified source unchanged.

CPU usage rises after enabling transcoding

تحقق
  • Compare source and requested output.
  • Remove unnecessary resize/frame-rate changes.
  • Review host capacity.
ثم نفّذ

Use pass-through when possible or reduce the profile to a measured capacity target.
