How to use gen_rtmp_client?

Hi @KallDrexx, Thanks so much for making this library. I'm very impressed with your work. But I'm curious about how can we use the gen_rtmp_client? I see adopter_module but actually not yet understand it. If you can describe more, it will be helpful, thanks.

Protocol handler should notify session handler of sent and received byte counts

Session handler should raise an event so GenRtmpServer adopters can handle acknowledgement messages (or lack thereof)

JW player is distorted if playback started before publishing

https://developer.jwplayer.com/tools/stream-tester/ is showing video that's incorrectly skinny if the player connects before the publisher starts pushing video.

`GenRtmpServer` should allow sending pings, and being notified of pongs

A server should be able to send an RTMP ping to the client and get notified of a pong response, and be able to disconnect a client if a pong is not received within a window.

Events should be raised up to behaviour adopters.

Investigate saving audio and video into mpeg-ts segments (for hls)

Video comes in via gen_rtmp_server adopter and gets saved in 10 second TS fragments (no hls manifest for phase 1)

Creates video stream on the fly

Hi,

It's nice to check your project, hopefully can become BIG soon :)
By the way... I contact you through this, is not for any issue (I haven't try yours yet), but I do have a question regarding your project.

Currently I'm still learning elixir phoenix, I'm creating a simple video conference meeting site where each user can meet others and have a video conversations (more than 2 users).
I managed to push a stream of images (base64 png without voice) to a channel, and planning to push it to each joined sockets, so each user can received it and renders it on their browser using an img tag every 40 milliseconds (25fps) --> but this approach creates skip frames on browser other than Chrome.

I wonder if your library can receives a stream of image files and converts it on the fly to video stream (in memory not disk) so I can push it to joined sockets?

Thanks :)
P.S my project is in my repo here, named portal.

Saving Raw Stream Data

Hello, I'm not sure if these packages are still used but I am modifying the simple rtmp server to save raw data from an OBS rtmp stream (the video and audio data) but I'm not sure what format the "data" bytes are in the event here: https://github.com/KallDrexx/elixir-media-libs/blob/master/apps/simple_rtmp_server/lib/simple_rtmp_server/worker.ex#L223

any guidance would be much appreciated 👍

Flash video players are stuttering at high bitrates

VLC seems fine, but flash players seem to be stuttering when sending between 3-5Mbps, and is choppy even at 1Mbps.

RTMP servers should be in charge of handling acknowledgement messages (and lack thereof)

RTMP sessions should surface an event when an acknowledgement message comes up.

Furthermore, modules adopting the GenRtmpServer behaviour should have some mechanism of knowing how many bytes it sent to the peer and if an acknowledgement is due, and allow disconnecting the connection if an acknowledgement didn't come back fast enough.

Add parsing of FLV audio tags

AAC only required for first iteration

Add generic RTSP server

Gen_Rtmp_Server should drop frames if A/V data gets backed up too much

Videos are stalling on flash players

No idea why yet :(

Create GenRtmpClient behaviour

There should be a GenRtmpClient behaviour that allows issuing connect, createstream, play, pause, closestream and publish commands, and allows sending and receiving audio/video data and metadata.

First iteration only requires one stream at a time.

This will include updating rtmp_session to successfully act as a client.

Incoming rtmp acknowledgements should bubble up to GenRtmpServer adopters

Update documentation for RTMP library

Add RTMP Authentication support

What is adopter_args?

Could you please tell me about adopter_args and what arguments should i pass?

Actionscript error occurs on Wowza test player on playback

When viewing a stream on https://www.wowza.com/testplayers, an actionscript 3 error occurs.

I assume this is because Wowza's test players are expecting an AMF3 onMetaData message and I'm sending it as an AMF0 message (since its sending me AMF0 encoded commands wrapped in an AMF3 message type).

I'd probably have to add an extra 0x00 in front of the AMF0 encodings and have it adjust the type to 15 instead of 18, but only in these situations
