X264 - Howto insert consecutive SPS/PPS

picturebuffer · 2nd December 2014, 18:08

If I see that correctly, a SPS/PPS NAL is written once into a x264 bitstream per default before the first IDR Frame in the Stream. I didn`t find a cli-trigger to have them written before every IDR Frame throughout the stream.

Anybody here know if that is possible without modifying the code?

By default x264 cli insert SPS/PPS NALs before every keyframe (IDR-frame) if you output to raw (Annex B) H.264 elementary stream. If you output to MKV/MP4/FLV than you will have SPS/PPS only ones because this formats mandates global headers.

So true. Thanks!
