Hi,

i encode video frames using a default codec configuration via avcodec_get_context_defaults3(). That video frames are further used for rtsp streaming based on live555. For compatibility i need the SPS and PPS-informations for the rtsp server but i didnt know them (cause default configurations i cant access).

How can i get that infos out of a AVCodecContext after setting to default values (c-code)?

Best regards and thanks for reading,
Christian

I figured out that those informations typically found in SDP-descriptions. So i tried av_sdp_create which works so far but it has no sprop-parameter-sets :/.

Cant be that hard - or?
