Using membrane in place of Medialive for a live-transcoder

[grant-zukowski-xumo]

Hi, my business use case has us digesting usually an HLS stream as a source, then transcoding (usually the highest variant) into another lower quality hls variant and or an RTP connection to an outside entity. So we may have one HLS input for example and want 2 outputs, HLS and/or RTP. Do you think I could run membrane on an EC2 instance and achieve this goal?

Hi there, that should be possible ;) See

• https://github.com/kim-company/membrane_hls_plugin for HLS ingest
• https://github.com/membraneframework/membrane_h264_ffmpeg_plugin for transcoding
• https://github.com/membraneframework/membrane_tee_plugin for connecting multiple outputs
• https://github.com/membraneframework/membrane_http_adaptive_stream_plugin for HLS egress
• https://github.com/membraneframework/membrane_rtp_plugin for RTP egress

To clarify, the example for https://github.com/kim-company/membrane_hls_plugin for HLS ingest we are using the HLS as our source. The example in this repo has the source as RTMP. I just wanted to make sure you are saying this library can let us use HLS as source.

I think I answered my own question. They are listing the rtmp out as #source, but I can see the HLS is used to ingest.

sorry I'm still not sure. I'm not sure the example in the https://github.com/kim-company/membrane_hls_plugin for HLS ingest is ingesting HLS.

The HLS plugin is for HLS ingest, while HTTP Adaptive Stream is for egress :P We're going to unify that one day. For the details of the HLS plugin it's best to ask its authors ;)

Thank you, another question, we are concerned about CUE markers and SCTE-35 messages. Are there libraries that let us manipulate these?

[mat-hek]

Nope, they would have to be supported by the HTTP adaptive stream plugin
