View Source Membrane.RTP.H264.Payloader (Membrane RTP H264 Plugin v0.19.0)

Payloads H264 NAL Units into H264 RTP payloads.

Based on RFC 6184

Supported types: Single NALU, FU-A, STAP-A.

Element options

Passed via struct Membrane.RTP.H264.Payloader.t/0

  • max_payload_size 

    non_neg_integer()

    Default value: 1400
    Maximal size of outputted payloads in bytes. Doesn't work in the single_nalu mode. The resulting RTP packet will also contain RTP header (12B) and potentially RTP extensions. For most applications, everything should fit in standard MTU size (1500B) after adding L3 and L2 protocols' overhead.

  • mode 

    :single_nalu | :non_interleaved

    Default value: :non_interleaved
    In :single_nalu mode, payloader puts exactly one NAL unit into each payload, altering only RTP metadata. :non_interleaved mode handles also FU-A and STAP-A packetization. See RFC 6184 for details.
