--- Comment #4 from Tim-Philipp Müller <t.i.m at zen.co.uk> ---
We decided to change the behaviour of the "alignment" property instead:

    mpegtsmux: make "alignment" property more useful for packetisation

    Currently the alignment property just makes sure that we
    output things in multiples of align*packet_size bytes, but
    with no clear maximum size. When streaming MPEG-TS over
    UDP one wants buffers with a maximum packet size of 1316.
    The alignment property so far would just output buffers
    that are a multiple of 1316 then.

    Instead we now make the alignment property output
    individual buffers with the alignment size, which
    is entirely backwards compatible with the expected
    behaviour up until now. For efficiency reason
    collect all those buffers in a buffer list and
    send that downstream.

    Also collect data to push downstream in a buffer
    list from the adapter if we don't align things,
    which is still more efficient because of the
    silly way the muxer currently creates output
    packets.
