When the number of inputs is more than one in the command line application, it is a multi-stream use case. In multi-stream use cases, multiple HDMIs are the same replica of a single source. Table: Multi-Stream Features provides information about the multi-stream features supported in various designs.
Note: When using Low Latency mode (LLP1/LLP2), the encoder and decoder are limited by the number of internal cores. The encoder has a maximum of four streams and the decoder has a maximum of two streams.
The command line application supports multi-streaming, multi-recording, or multi-display. This Figure shows a use case of the vcu_gst_app running three HDMI and one MIPI in multi-stream in 1080p60 resolution. For 4-1080p60 input, the source type can be TPG, MIPI, or HDMI. For multi-streaming or multi-recording, the source type can be TPG, HDMI, or MIPI.
This Figure shows a use case of the vcu_gst_app running seven HDMI and one MIPI in multi-stream in 1080p30 resolution. For 8-1080p30 input, the source type can be MIPI or HDMI. Here only half of each stream is displayed to showcase eight different streams on a single screen.
