Error in SEI when interlace encoding is used

[Former user]

Hi,

There is error in the picture struct in SEI when interlace encoding mode is used.

The err is when interlaceMode=1, the output picStruct will always be 2 (bot)

the code is at source/encoder/frameencoder.cpp

sei.m_picStruct = (slice->getPOC() & 1) && m_cfg->param->interlaceMode == 2 ? 1 /* top */ : 2 /* bot */;

Tested fix for this is as follows:

sei.m_picStruct = (slice->getPOC() & 1) ? ( m_cfg->param->interlaceMode == 2 ? 1 /* top */ : 2 /* bot */) : ( m_cfg->param->interlaceMode == 2 ? 2 /* bot */ : 1 /* top */) ;

Thanks!
