Does Facebook multicast or unicast the live videos to its viewers ?
14 avril 2018, par Kamran ZahoorThis is how a live stream goes from one broadcaster to millions of viewers :
- A broadcaster starts a live video on their phone.
- The phone sends a RTMP stream to a Live Stream server.
- The Live Stream server decodes the video and transcodes to multiple bit rates.
- For each bit rate a set of one-second MPEG-DASH segments is continuously produced.
- Segments are stored in a datacenter cache.
- From the datacenter cache segments are sent to caches located in the points of presence (a PoP cache).
- On the view side the viewer receives a Live Story.
- The player on their device starts fetching segments from a PoP cache at a rate of one per second.
My question is simple. After the step 6, does PoP cache/Edge cache/eNB (edge layer node) multicast a live video content to multiple viewers or unicast each user separately (opening up seperate streams for each user) ?

Can we detect whether a live udp stream packet contains a key frame or not ?
12 janvier 2023, par Miuru Shalinda RajapakshaIs there a way to detect whether there is a key frame within a video packet or not ?


What I want do is I want to cut the live udp stream into seperate 30 second .ts files, and then concatenate the files including several other .ts file using ffmpeg and restream to rtmp (youtube). I can achieve this but the only problem I have is after concatenating the files there is drop frame after each 30 seconds, the reason for this is I have cut the live stream without considering the key frames. Therefore what I want is to cut the live stream based on its key frames. Im doing this using python and ffmpeg. Is there a way to detect whether a video packet contains a key frame or not ?

FFMPEG to remote server : Live streaming with segments [migrated]
10 août 2013, par BrianjsI have looked around and have found many good articles on how to use ffmpeg to segment live video for HLS streaming. However, I need to be able to use use an encoder from a remote location (that is receiving live video), and then somehow send these segmented files and the m3u8/ts files to a web server in a different location, in real time.
So :
REMOTE COMPUTER(camera->ffmpeg->segmenter) -> WEBSERVER(receives files -> users connect for "live" stream)My question is : Has anyone seen something similar to this ? Or is there a setting on ffmpeg/ffserver that will let me do this ?
