Live streaming from iphone To wowza server
4 décembre 2013, par user2959377I need to develop an iphone app that streams live video to wowza server. For encoding the captured video in H.264 and to compress it i need to use FFmpeg. I am unable to proceed because of limited content on internet explaining compilation of FFmpeg.
I used https://github.com/lajos/iFrameExtractor to start with compiling of FFmpeg, but i dont understand how to use the generated files in my application. I am using AVFoundation and can successfully generate the video but dont know how to compile the captured video through FFmpeg. Any link that could help in starting with compiling and using ffmpeg in iphone would be of great help. -
HTML5 live streaming with alpha channel
5 mars 2021, par air5We are trying to live stream a video file with alpha channel. Adaptive streaming would be great, but it's not a must. Streaming is pretty new territory for us.


We found out that WebM (VP9) seems to be the only format in the web that supports alpha channel. We tried using the nginx-rtmp-module as streaming server (MPEG-DASH) and broadcast the file with ffmpeg. But the alpha channel was lost. Probably because RTMP required us to broadcast the video as a FLV which doesn't support alpha.


Is anyone having experience in streaming rgba videos on the web ? Getting to know compatible commercial solutions would be interesting tee. My next approaches would be trying to use Icecast. There is not much information online but this article where streaming a webm directly seems to be possible.
