MPEG-4 container plugin for Membrane Framework View Source
This plugin provides utilities for MP4 container parsing and serialization along with elements for muxing the stream to MP4 or CMAF.
Installation
The package can be installed by adding membrane_mp4_plugin
to your list of dependencies in mix.exs
:
defp deps do
[
{:membrane_mp4_plugin, "~> 0.10.0"}
]
end
Usage
Membrane.MP4.Muxer.ISOM
For an example of muxing streams to a regular MP4 file, refer to
examples/muxer_isom.exs
.
To run the example, you can use the following command:
elixir examples/muxer_isom.exs
You can use MP4_OUTPUT_FILE
environment variable to set location of the output file (defaults to example.mp4
).
### Membrane.MP4.Muxer.CMAF
To use the output stream of the CMAF muxer, you need a sink that will dump it to a playlist in a proper format.
In membrane_http_adaptive_stream_plugin
repository you can find an example that uses the CMAF muxer to create an HTTP Live Streaming playlist.
## Updating tests
In case out_*
reference files in test/fixtures/cmaf
change, out_playlist.m3u8
and its dependent playlists should be updated and checked if they are still playable.
The current files have been checked with ffplay (FFmpeg) and Safari.
