1. If the preview effect meets your requirements, you can click To PGM to start the output.
Note:
A red frame appears on the input source or layout being used for output, indicating that the input source or layout is in use in PGM.
Once the stream is published to PGM, formal output and billing start. Closing the LVC console will not stop the live streaming or PGM output; in contrast, the LVC remains in operation and the billing continues. To stop the LVC, you need to manually turn off the PGM.
2. Before publishing the stream, the system once again verifies whether to turn on the main monitor (PGM).
3. Once the output starts, you can see the published stream in the main monitor.
Step 2: Obtaining the Output Playback URL
1. After the stream is published to PGM, if you want to obtain the output playback URL, you may click Details in the upper-right corner to enter the details page.
2. Click Generate to enter the Address Generator to generate the URL.
If you have not set a live streaming playback domain, this section is blank and you cannot play the stream through Tencent Cloud CDN.
If you have multiple domains, the LVC system will randomly select a domain to compute a playback URL for display. If the randomly selected domain does not meet your needs, you may go to the live streaming system to generate a playback URL.
Step 3: Recording the Live Stream
1. Click
in the main monitor (PGM) to enter the recording configuration page.
2. Select a recording template you configured and set the recording end time. The maximum recording duration is 24 hours. Click Confirm to start recording.
3. When the recording is completed, click
.
4. Click Confirm to finish the recording.
5. The system transmits the recorded file to the Video on Demand (VOD) system. You can view the recorded file in VOD.
6. Click Details in the upper-right corner to enter the details page and view or copy the prefix of your recording file.
Note:
You may navigate to VOD > Application Management, select an application, and click Enter Application to access the Media Asset Management Guide.
On the Audio/Video Management page, you can search for a recorded video by entering its file prefix.
Step 4: Setting a Relay
To push your live stream to a third-party cloud vendor, configure a relay first.
1. Click
in the upper-right corner and select Publish to enter the push settings page.
2. Fill in the CSS stream name.
3. You may enable delayed playback. The maximum delay is 300 seconds.
4. Click Advanced settings to configure the domain and parameters.
Advanced Settings
Required
Description
Push domain
No
Select an available push domain. If not filled out, this field will be populated by a backend-generated value when you save settings.
AppName
No
Use English letters, numbers, and underscores only.
Custom parameters
No
Enter stream push parameters.
5. Set a relay address:
5.1 Click
to add a custom third-party vendor address.
Note:
Third-party relays can only be RTMP-based. Platform push addresses should be in the format of rtmp://domain/app/stream?arg1=xxx.
To use the third-party relay feature, you must use Tencent Cloud Streaming Services.
A maximum of three target addresses are supported in third-party relay. One of the target addresses defaults to the current Tencent Cloud Streaming Services account, and the other two can be third-party addresses, excluding streaming domain names under the current account. Relay to third parties incurs relay bandwidth-based fees, which are calculated according to the relay charging standard.
Relay to other Tencent Cloud Streaming Services accounts (other than those under the current account) also incurs bandwidth-based fees, which are calculated according to the relay charging standard. For more information, see Live Video Caster Charging Instructions.
6. Set the size of video output.
Select Custom, and set the following parameters:
Video width: Must be less than or equal to 1920px. Video height: Must be less than or equal to 1920px.
Frame rate: Must be less than or equal to 60fps. Video bitrate: Must be less than or equal to 10,000kbps.
Audio bitrate: Supports 128kbps, 192kbps, and 256kbps.
7. Click Confirm to save the settings.
Step 5: Setting a Standby Input Source
You may enable a standby input source on the standby stream page.
1. Click
in the upper-right corner and select Standby stream to enter the standby stream page.
2. Enable or disable the standby video. A standby video serves as an auxiliary input source. If the standby video function is enabled, when the input source or pulled stream for the PGM (primary stream) fails or is interrupted, LVC automatically switches to the standby video. Once the primary stream recovers, LVC switches back to the primary stream.
3. Set the input type to On demand URL or Live URL.
On demand URL: You may set multiple on-demand URLs, which should be separated with semicolons (;) or line breaks.
Live URL: Fill in this field with the stream/playback URL.
4. Enable or disable the standby image. A standby image serves as an auxiliary image input source. If the standby video function is not enabled, when the input source or pulled stream for the PGM (primary stream) fails or is interrupted, LVC automatically switches to the standby image. Once the primary stream recovers, LVC switches back to the primary stream.
5. Click Upload and upload a standby image. The size limit is 5MB, and the image format should be PNG, JPG or JPEG.
6. Click Confirm to save the settings.
Note:
If the standby video and standby image functions both are enabled, LVC switches to the standby video first. Only when the standby video also fails, LVS switches to the standby image.
Step 6: Monitoring Output Stream Quality
After the stream is output from the LVC, you can view the frame rate and bit rate curves in the Monitor section.
1. Click Refresh in the upper-right corner to refresh the current chart.
2. Click Stream data to enter the stream detail query page where you can view the detailed push stream data.
