4. Use the –h option to determine the usage of the decode example applications and execute the
decode example applications with the necessary parameters
target $ ./video_decode_io2_omap3530.x470MV –h
target $ ./audio_decode_io1_omap3530.x470MV –h
target $ ./image_decode_io1_omap3530.x470MV –h
5. The input files for audio decode are available at
/home/<useracct>/dvsdk_#_##_##_##/clips/omap3530/data/sounds
6. The input files for video decode are available at
/home/<useracct>/dvsdk_#_##_##_##/clips/omap3530/data/videos
7. The input files for image decode are available at
/home/<useracct>/dvsdk_#_##_##_##/clips/omap3530/data/images, where ## are the version
numbers
8. Given below is the example execution using the media files included in DVSDK. Unless otherwise
specified, the DMAI video decode examples support default video output resolution of 720x480
and the number of frames decoded is 100. The DMAI image examples support decoded image
output color space as YUV 4:2:2 ILE
a. MPEG4 SP Decoder
target $ ./video_decode_io2_omap3530.x470MV
data/videos/davincieffect_ntsc_1.m4v -o mpeg4_test_output.yuv
b. H.264 BP Decoder
target $ ./video_decode_io2_omap3530.x470MV
data/videos/davincieffect_ntsc_1.264 -o h264_test_output.yuv
c. MPEG2 MP Decoder
target $ ./video_decode_io2_omap3530.x470MV
data/videos/davincieffect_ntsc_1.m2v -o mpeg2_test_output.yuv
d. JPEG Decode
target $ ./image_decode_io1_omap3530.x470MV –c jpegdec -i shrek_720x480.jpg -o
jpeg_test_output.yuv
The resolution is 720x576 and the decoded output color space format is YUV422 ILE.
e. AAC Audio Decode
target $ ./audio_decode_io1_omap3530.x470MV -c aachedec -i
data/sounds/davincieffect_HEv2.aac -o aac_test_output.pcm
