uftrace for JM
This document is written by Hyuck Kang.
JM (Joint Test Model) is The reference software for H.264/MPEG-4 AVC. Advanced Video Coding (H.264/MPEG-4 AVC) is a joint video coding standardization project of the ITU-T Video Coding Experts Group (ITU-T Q.6/SG 16) and ISO/IEC Moving Picture Experts Group (ISO/IEC JTC 1/SC 29/WG 11).

JM officially provides a sample test sequence, foreman_part_qcif.yuv, 176x144 size, yuv420 foramt, 3 frames.
you can find sample test sequence in JM/cfg directory.
Copy sample test sequences and cfg file to JM/bin directory.
$ cp ../cfg/encoder.cfg .
$ cp ../cfg/foreman_part_qcif.yuv .
$ uftrace record --no-libcall ./lencod_static
Enjoy H.264/AVC video codec encoding algorithm with uftrace :)
