Viewing Captured Image/Video Content

Recorded video files can be viewed with:
gst-play-1.0 test.mp4
If you want to see the decoded framerate of the video during the playback, use the following command:
gst-launch-1.0 -v filesrc location=test.mp4 !
queue !
 qtdemux ! vaapidecodebin ! fpsdisplaysink text-overlay=false video-sink="vaapisink fullscreen=true" fps-update-interval=1000
To show a captured JPEG image using Gstreamer:
gst-launch-1.0 filesrc location=image.jpeg ! jpegdec ! imagefreeze ! autovideosink
Use this command to show a raw NV12 format image using Gstreamer. This type of image is produced by the example test cases.
gst-launch-1.0 filesrc location=image_640x480.nv12 ! videoparse width=640 height=480 format=nv12 ! autovideoconvert ! imagefreeze ! autovideosink
 

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
