Table 1. GStreamer Decode Properties
Property Description
internal-entropy-buffers

Specifies decoder internal entropy buffers, used to smooth out entropy decoding performance.

Default: 5. Range [2, 16].

Set this value to 10 for higher bitrate use cases. For example, use cases where the bitrate is more than 100 Mb/s. Increasing buffering-count increases decoder memory footprint.

low-latency When enabled, buffers will be pushed before they are evicted from the DBP, reducing decoding latency.
split-input When enabled, decoder will have 1-to-1 mapping for input and output buffers. When disabled, decoder will copy all input buffers to internal circular buffer and process them. Default: false.
qos Enables handling of Quality-of-Service events from downstream
output-position Coordinates of the start of pixel data in the output video buffer. Default: <0, 0>.
disable-realtime Disable decoder resource allocation limit validation. Default: false.
