9.2 Video Decoding
Hardware accelerated video decoding requires the GStreamer/OpenMAX framework and a special NVIDIA ®
nvgstplayer application or gst-launch as a command line tool. KONTRON Technology A/S does not know
another programs which can play a H.264 main profile video stream (720p) without dropouts (e.g. Totem
Movie Player, MPlayer or VLC).
The following table gives an overview about the limitations:
Video Format Profile / Level Max. Resolution / Frame Rate Max. Throughput Comment
DivX 4/5/6 1080p HD 1920 x 1080 / 30 fps 10 Mbps
Xvid Highdef 1920 x 1080 / 30 fps 10 Mbps
MPEG-4 Advanced Simple / L4 1920 x 1080 / 30 fps 10 Mbps
H.264 Baseline (BP) / L4 1920 x 1080 / 30 fps 10 Mbps
H.264 Main (MP) / L3.1 1280 x 720 / 30 fps 4 Mbps CAVLC
H.264 Main (MP) / L3.1 1280 x 720 / 30 fps 4 Mbps CABAC, CAVLC
H.264 High (HiP) / L3.1 1280 x 720 / 30 fps 4 Mbps CAVLC
H.264 High (HiP) / L3.1 1280 x 720 / 30 fps 4 Mbps CABAC, CAVLC
Please note that the maximal throughput data are peak values not average values. You may need to re-
encode your videos with parameters above to get smooth video output.
