1. Video time stamp
PTS = inc++ * (1000/fps); Where Inc is a static, initial value of 0, each time the timestamp Inc plus 1.
In FFmpeg, the code in
pkt.pts= m_nvideotimestamp++ * (M_vctx->time_base.num * 1000/m_vctx->time_base.den);
2. Audio time stamp
PTS = inc++ * (frame_size * 1000/sample_rate)

Automatic parameter identification technology, the transfer of video can maintain the highest definition while the file is kept to the minimum, faster conversion speed.
To ensure the same quality of high-quality, under the premise of the transfer of video than similar software conversion results file 40% small.
