Track order management in RTMP stream
Most players on various platforms suppose video track to be first in RTMP stream. To guarantee this order and to send videodata before audiodata, set the following parameter in flashphoner.properties file:
| Code Block | ||
|---|---|---|
| ||
rtmp_send_video_first=true |
Note that if this setting is active, a stream containing audio track only can not be played as RTMP because audiodata will not be sent to client.
RTMP playback sound suppression
Sound may be disabled while stream published on server playback as RTMP. To do this, the following RTMP URL parameter should be passed:
| Code Block | ||
|---|---|---|
| ||
rtmp://yourserver:1935/live?suppress_sound=true/streamName |
In this case audio track will be replaced by silence.
Disabling RTMP playback
By default, RTMP playback is enabled. Since build 5.2.1081 this feature may be disabled if needed
