# Membrane MPEG.TS Plugin
MPEG-TS Demuxer and Muxer for the Membrane Framework.
This element is used in production.
## Installation
Add to your `mix.exs`:
```elixir
def deps do
[
{:membrane_mpeg_ts_plugin, "~> 2.1"}
]
end
```
## Usage
### Demuxer
Extract streams by PID:
```elixir
spec = [
child(:source, %Membrane.File.Source{location: "input.ts"})
|> child(:demuxer, Membrane.MPEG.TS.Demuxer),
get_child(:demuxer)
|> via_out(:output, options: [pid: 0x100])
|> child(:video_sink, %Membrane.File.Sink{location: "video.h264"}),
get_child(:demuxer)
|> via_out(:output, options: [pid: 0x101])
|> child(:audio_sink, %Membrane.File.Sink{location: "audio.aac"})
]
```
Extract streams by type:
```elixir
get_child(:demuxer)
|> via_out(:output, options: [stream_type: :H264_AVC])
|> child(:video_sink, sink)
get_child(:demuxer)
|> via_out(:output, options: [stream_category: :video])
|> child(:video_sink, sink)
```
Extract streams by profile (stream_type + descriptors + depacketizer):
```elixir
get_child(:demuxer)
|> via_out(:output, options: [profile: :opus_mpeg_ts])
|> child(:audio_sink, sink)
```
PMT notification:
```elixir
assert_pipeline_notified(pid, :demuxer, {:pmt, %MPEG.TS.PMT{}})
```
### Muxer
```elixir
spec = [
child(:h264_source, source)
|> via_in(:input, options: [stream_type: :H264_AVC])
|> get_child(:muxer),
child(:aac_source, source)
|> via_in(:input, options: [stream_type: :AAC_ADTS])
|> get_child(:muxer),
child(:muxer, Membrane.MPEG.TS.Muxer)
|> child(:sink, %Membrane.File.Sink{location: "output.ts"})
]
```
Mux with a profile (adds descriptors and packetizes payloads when needed):
```elixir
child(:opus_source, source)
|> via_in(:input, options: [profile: :opus_mpeg_ts])
|> get_child(:muxer)
```
Custom payloads via descriptors (e.g. JSON in PES private data):
```elixir
child(:json_source, source)
|> via_in(:input, options: [
stream_type: :PES_PRIVATE_DATA,
descriptors: [%{tag: 0x05, data: "JSON"}]
])
|> get_child(:muxer)
```
Available profiles:
- `:opus_mpeg_ts`
- `:scte35`
