Note: The data provided is based on measured performance and is intended for reference only. Actual performance may vary due to environmental factors.

Compared to FFmpeg, the GStreamer has an extra copying step when handling the YUV decoding buffer, so it will be slower.

Test Sample flow

  1. Get 1080P YUV 300 frames

gst-launch-1.0 -v videotestsrc num-buffers=300 ! video/x-raw,width=1920,height=1080,framerate=30/1,format=NV12 ! filesink location=/tmp/1080p.yuv

  1. GStreamer H264 encode 1080P stream 300 frames

# gst-launch-1.0 filesrc location=/tmp/1080p.yuv ! rawvideoparse width=1920 height=1080 format=nv12 colorimetry=bt601 framerate=60/1 ! v4l2h264enc ! fakesink Setting pipeline to PAUSED ... Pipeline is PREROLLING ... Redistribute latency... Pipeline is PREROLLED ... Setting pipeline to PLAYING ... Redistribute latency... New clock: GstSystemClock Got EOS from element "pipeline0". Execution ended after 0:00:04.641600600 Setting pipeline to NULL ... Freeing pipeline ...

  1. GStreamer H264 decode 1080P stream 300 frames
