@ -1091,69 +1091,35 @@ This muxer implements ISO 13818-1 and part of ETSI EN 300 468.
The recognized metadata settings in mpegts muxer are @code{service_provider}
and @code{service_name}. If they are not set the default for
@code{service_provider} is "FFmpeg" and the default for
@code{service_name} is "Service01".
@code{service_provider} is @samp{FFmpeg} and the default for
@code{service_name} is @samp{Service01}.
@subsection Options
The muxer options are:
@table @option
@item mpegts_original_network_id @var{number}
Set the original_network_id (default 0x0001). This is unique identifier
of a network in DVB. Its main use is in the unique identification of a
service through the path Original_Network_ID, Transport_Stream_ID.
@item mpegts_transport_stream_id @var{number}
Set the transport_stream_id (default 0x0001). This identifies a
transponder in DVB.
@item mpegts_service_id @var{number}
Set the service_id (default 0x0001) also known as program in DVB.
@item mpegts_service_type @var{number}
Set the program service_type (default @var{digital_tv}), see below
a list of pre defined values.
@item mpegts_pmt_start_pid @var{number}
Set the first PID for PMT (default 0x1000, max 0x1f00).
@item mpegts_start_pid @var{number}
Set the first PID for data packets (default 0x0100, max 0x0f00).
@item mpegts_m2ts_mode @var{number}
Enable m2ts mode if set to 1. Default value is -1 which disables m2ts mode.
@item muxrate @var{number}
Set a constant muxrate (default VBR).
@item pcr_period @var{numer}
Override the default PCR retransmission time (default 20ms), ignored
if variable muxrate is selected.
@item pat_period @var{number}
Maximal time in seconds between PAT/PMT tables.
@item sdt_period @var{number}
Maximal time in seconds between SDT tables.
@item pes_payload_size @var{number}
Set minimum PES packet payload in bytes.
@item mpegts_flags @var{flags}
Set flags (see below).
@item mpegts_copyts @var{number}
Preserve original timestamps, if value is set to 1. Default value is -1, which
results in shifting timestamps so that they start from 0.
@item tables_version @var{number}
Set PAT, PMT and SDT version (default 0, valid values are from 0 to 31, inclusively).
This option allows updating stream structure so that standard consumer may
detect the change. To do so, reopen output AVFormatContext (in case of API
usage) or restart ffmpeg instance, cyclically changing tables_version value:
@example
ffmpeg -i source1.ts -codec copy -f mpegts -tables_version 0 udp://1.1.1.1:1111
ffmpeg -i source2.ts -codec copy -f mpegts -tables_version 1 udp://1.1.1.1:1111

through the path @samp{Original_Network_ID, Transport_Stream_ID}. Default
is @code{0x0001}.
@table @option
@item mpegts_service_id @var{integer}
Set the @samp{service_id}, also known as program in DVB. Default is
@code{0x0001}.
@item mpegts_service_type @var{integer}
Set the program @samp{service_type}. Default is @code{digital_tv}.
