[x264-devel] without SPS/PPS?

[Takashi Mochizuki]

Simple question.

Is it true that current x264 could emit stream without SPS/PPS?

- SPS, PPS is emitted only when x264_encoder_headers() is called.
- on the other hand, ffmpeg svn19977 shows GlobalHeader flag requires  
to make SPS/PPS
- It seems that ffmpeg without GLOBAL_HEADER flag build avc stream  
without SPS/PPS.

My understanding is as following:
- sps/pps should be embed at least once at start, or into stream  
periodically if stream is not in, such like mp4 file format.

I am afraid of my misunderstanding.
