Hi list, I've been struggling with some pipeline after a few days and
would like to ask you a few questions, here is my scenario: I am receiving VP8/H264 & Opus through RTP, no RTCP yet. I built a pipeline using RtpBin and Auto(Video/Audio)Sink to play those streams with "autosink" for audio and video and it works great. I built another pipeline to push to an RTSP server and I am struggling with it, especially when video comes in VP8. For h264/opus it works fine, perhaps it takes a few seconds to display video but then (local network) it runs fine. The problem arises with VP8 when I was unable to play video at first, until I've put "video/x-vp8,width=1280,height=720" in between depay and sink to avoid clients complaining about not recognizing the size of video (which didn't make much sense to me, since I have the understanding that you could figure out frame properties after first keyframe with vp8), but I've realized I've been with GST 1.17, then after update to latest version, clients started to complain about size again and now I am unable to reproduce a single VP8 frame with any client that I've tested with. I've read logs carefully while building the pipeline and couldn't get information to fix this issue. Here are a few questions: * Is it possible to set which will be the output size of VP8, and is it actually required or the problem comes from somewhere else? * Is it ok to use RtpBin without RTCP support to deliver to RTSP? * There is some extra processing required to make it work with the VP8 scenario? * Does it make sense to use GST RTSP Server over other open source options out there? Below is an example pipeline I've been testing.
