Synopsis
========
IDR integration

Branches: HEAD

Reviewer: Anyone

Description
===========
I. Intro
========
IDR: Instantaneous Decoding Refresh
IDR frame belongs to I frame, the frames after IDR frame, can not quote the content \
of the frames before IDR frame, in the opposite situation, B frames or P frames after \
an I frame can quote the content of the frames before the I frame. So in a random \
access situation, the Helix server will find the segment according the random access \
point first, then the frame will be analysed according other frames of the segment \
where it belongs to To support verimatrix player, helix server make the first frame \
of ts file key frame. Make the PID and SID equal to each ts file if MR.

II. What feature has been implemented in Helix Server 

========================================================
1. Enable/Disable IDR frame feature on admin page, and save to rmserver.cfg.
2. Make the first frame of ts file IDR frame.
3. If MR, make the PID equal to each ts file, and so does SID.
4. Ensure ts duration don't less than the value configured in rmserver.cfg.

III. Solution Description
=========================
1. Add config option on admin page, get option value from rmserver.cfg.
2. Add IDRController struct, after analyze stream, pass this struct from \
CStreamHandler to CTSArchiver. 3. In CTSArchiver, add the API IsKeyFrame() to check \
whether the frame is key frame or not by IDRController and ASMFlag,  add the API \
IsKeyFrameAligned() to check streams are aligned or not when MR, if not aligned, the \
error log will be output to rmerror.log. 4. If IDR frame enabled, set PID by value of \
PROGAM_MAP_PID_START and SID is the sum of ELEMENTARY_PID_START and StreamGroupNumber \
in CMPEG2TSMuxer. 5. If only audio, consider every frame as key frame.
6. If IDR frame enabled, HandleIDRPacketReady() will be called to handle packet in \
CTSArchiver. If this packet is key frame and the total duration of packets in queue \
is longer than value configured in rmserver.cfg, write pakets in queue to ts file. \
Then or else, this packet is put in queue. 7. when user seek, calculate the new \
position using duration of all ts file. then rewrite the m3u8 file. In the previous \
version, the duration of every ts file is equal except last one. so calculate the \
seek position by divided ts number with no remainder. 8.update the value of \
"#EXT-X-TARGETDURATION" in m3u8 file using the average duration of total ts file. 9 \
Not deal with audio only this time, so its segment duration will be same as the \
configuraton value in rmserver.cfg.

VI. New files
==============
server15/common/include/hxidrframe.h

VII. Testing Performed
======================
1. Test platform: Windows7(32-Bit), Radhat(64-Bit).
2. Test on iphone and verimatrix.
3. Test case:
 1) Admin page for LDR frame enabled, and check the rmserver.cfg.
 2) MR vod playback on iphone, and check m3u8 file.
 3) The PID and SID must be the same value, check these on TSreader.
 4) MR vod playback on verimatrix, check m3u8 file.
 5) The first frame of every segments must be IDR frame.

QA Hints
========
Need lots of test to verify MR stream by verimatrix.
