The streaming output can be used for any kind of classical streaming, such as **rtmp, srt, rtp**, etc. Any streaming type supported by ffmpeg should work.
If you want to use different resolutions, you should apply them in order from largest to smallest. Use the largest resolution in the config under `processing:` and the smaller ones in `output_params:`.
In desktop mode, you will get your picture on the screen. For this, you need a desktop system; theoretically, all platforms should work here. ffplayout will require **ffplay** for that.
HLS output is currently the default, mostly because it works out of the box and doesn't need a streaming target. By default, it saves the segments to **/usr/share/ffplayout/public/live/**.
The tee pseudo-muxer in FFmpeg is crucial in live streaming scenarios where a single input needs to be encoded once and then broadcast to multiple outputs in different formats or protocols. This feature significantly reduces computational overhead and improves efficiency—in my tests, it achieved a 200% reduction in CPU processing expenditure—by eliminating the need for multiple FFmpeg instances or re-encoding the same input multiple times for different outputs.
**FFmpeg's Tee Pseudo-Muxer Parameter Configuration:**
The configuration of the tee pseudo-muxer in FFmpeg allows for the broadcasting of a single input to multiple outputs simultaneously, each with specific settings. This is accomplished by specifying distinct formats and protocols for each output within a single command line, thus minimizing computational load by avoiding re-encoding for each target.
**1. `-f tee`**: Specifies the use of the tee pseudo-muxer, which facilitates the multiplexing of the broadcast.
**2. Use of “|” (pipe)**: The pipe symbol "|" acts as a separator between the different outputs within the tee command. Each segment separated by a pipe configures a distinct output for the broadcast.
Each stream is processed by the tee pseudo-muxer, which encodes the input only once, directing it to various outputs as specified, thereby allowing for efficient and less resource-intensive operation.
