It's not enough to have timeout or event based VPS/SPS/PPS information sent in RTP packets. There are some scenarios when key frames may appear more frequently than once a second, in which case the minimum timeout for "config-interval" of 1 second for sending VPS/SPS/PPS isn't enough. It might also be desirable in general to make sure the VPS/SPS/PPS is available with every keyframe (packet loss aside), so receivers can actually pick up decoding immediately from the first keyframe if VPS/SPS/PPS is not signaled out of band. This commit adds the possibility to send VPS/SPS/PPS with every key frame. This mode can be enabled by setting "config-interval" property to -1. In this case the payloader will add VPS, SPS and PPS before every key (IDR) frame. https://bugzilla.gnome.org/show_bug.cgi?id=757892 |
