Examples

To perform decoding without saving decoded output

Enter this command:

./nvm_ide_sci -c 4 -f disney.264

The command starts decoding the disney.264 H.264 stream and does not save the output YUV to a file.

To perform decoding and save decoded output

Enter this command:

./nvm_ide_sci -c 4 -f disney.264 -s disney_out.yuv

The command starts decoding the disney.264 H.264 stream and saves the decoded frames to the disney_out.yuv file.

To specify the number of frames to decode

To specify the number of frames to decode, enter this command:

./nvm_ide_sci -c 4 -f disney.264 -n 100

This example decodes the first 100 frames from the disney.264 file without saving the output to a file.

To specify the number of times to decode the frames, enter this command:

./nvm_ide_sci -c 4 -f disney.264 -l 10

This example decodes disney.264 ten times.

To generate CRC for decoded YUV

Enter this command:

./nvm_ide_sci -c 4 -f disney.264 -crc gen -crcpath disney_PitchLinear_Ref_CRC.txt

This example decodes the stream disney.264 and generates CRC of the decoded YUV, and then saves it in the file disney_PitchLinear_Ref_CRC.txt.

To check CRC for decoded YUV against a reference CRC

Enter this command:

./nvm_ide_sci -c 4 -f disney.264 -crc chk -crcpath disney_PitchLinear_Ref_CRC.txt

This example decodes the stream disney.264, computes CRC of the decoded YUV, and compares it with the reference CRC disney_PitchLinear_Ref_CRC.txt. It prints if the CRC matches the reference. If there is a mismatch, then the decoding is incorrect.

To get the decode timing information

Enter this command:

./nvm_ide_sci -c 4 -f disney.264 -prof

This example decodes the stream disney.264 and prints information about the average time taken per frame and the total time taken for the sequence.
