  • f6a20eb1a   V4L/DVB: Add FE_CAN_TURBO_FEC ... Browse Code »

    Some (North American) providers use a non-standard mode called
    "8psk turbo fec". Since there is no flag in the driver that
    would allow an application to determine whether a particular
    device can handle "turbo fec", the attached patch introduces
    FE_CAN_TURBO_FEC.

    Since there is no flag in the SI data that would indicate
    that a transponder uses "turbo fec", VDR will assume that
    all 8psk transponders on DVB-S use "turbo fec".

  • 98293ef3e   V4L/DVB (12997): Add the DTV_ISDB_TS_ID property for ISDB_S ... Browse Code »

    In ISDB-S, time-devision duplex is used to multiplexing several waves
    in the same frequency. Each wave is identified by its own transport
    stream ID, or TS ID. We need to provide some way to specify this ID
    from user applications to handle ISDB-S frontends.

    This code has been tested with the Earthsoft PT1 driver.

  • b6e760f30   V4L/DVB (12892): DVB-API: add support for ISDB-T and ISDB-Tsb (version 5.1) ... Browse Code »

    This patch increments the DVB-API to version 5.1 in order to reflect the addition of ISDB-T and ISDB-Tsb on Linux' DVB-API.

    Changes in detail:
    - added a small document to describe how to use the API to tune to an ISDB-T or ISDB-Tsb channel
    - added necessary fields to dtv_frontend_cache
    - added a smarter clear-cache function which resets all fields of the dtv_frontend_cache
    - added a TRANSMISSION_MODE_4K to fe_transmit_mode_t

  • 1cb662a31   V4L/DVB (12275): Add two new ioctls: DMX_ADD_PID and DMX_REMOVE_PID ... Browse Code »

    DMX_ADD_PID allows to add multiple PIDs to a transport stream filter
    previously set up with DMX_SET_PES_FILTER and output=DMX_OUT_TSDEMUX_TAP.

    DMX_REMOVE_PID is used to drop a PID from a filter.

    These ioctls are to be used by readers of /dev/dvb/adapterX/demuxY. They
    may be called at any time, i.e. before or after the first filter on the
    shared file descriptor was started.

    They make it possible to record multiple services without the need to de-
    or re-multiplex TS packets.

    To accomplish this, dmxdev_filter->feed.ts has been converted to a list
    of struct dmxdev_feeds, each containing a PID value and a pointer to a
    struct dmx_ts_feed.

  • 85efde6f4   make exported headers use strict posix types ... Browse Code »

    A number of standard posix types are used in exported headers, which
    is not allowed if __STRICT_KERNEL_NAMES is defined. In order to
    get rid of the non-__STRICT_KERNEL_NAMES part and to make sane headers
    the default, we have to change them all to safe types.

    There are also still some leftovers in reiserfs_fs.h, elfcore.h
    and coda.h, but these files have not compiled in user space for
    a long time.

    This leaves out the various integer types ({u_,u,}int{8,16,32,64}_t),
    which we take care of separately.

  • cb889a2f3   V4L/DVB (10164): Add missing S2 caps flag to S2API ... Browse Code »

    The attached patch adds a capability flag that allows an application
    to determine whether a particular device can handle "second generation
    modulation" transponders. This is necessary in order for applications
    to be able to decide which device to use for a given channel in
    a multi device environment, where DVB-S and DVB-S2 devices are mixed.

    It is assumed that a device capable of handling "second generation
    modulation" can implicitly handle "first generation modulation".
    The flag is not named anything with DVBS2 in order to allow its
    use with future DVBT2 devices as well (should they ever come).

  • b01cd9378   V4L/DVB (7293): DMX_OUT_TSDEMUX_TAP: record two streams from same mux, resend ... Browse Code »

    Currently (in linux-2.6.24, but linux-dvb hg looks similar), the
    dmx_output_t in the dmx_pes_filter_params decides two things: whether
    output is sent to demux0 or dvr0 (in dmxdev.c:dvb_dmxdev_ts_callback),
    *and* whether to depacketise TS (in dmxdev.c:dvb_dmxdev_filter_start).
    As it stands, those two things can't be set independently: output
    destined for demux0 is depacketised, output for dvr0 isn't.

    This is what you want for capturing multiple audio streams from the same
    multiplex simultaneously: open demux0 several times and send
    depacketised output there. And capturing a single video stream is fine
    not what you want: you want multi-open (so demux0, not dvr0), but you
    want the TS nature preserved (because that's what you want on output, as
    you're going to re-multiplex it with the audio).

    At least one existing solution -- GStreamer -- sends all its streams
    simultaneously via dvr0 and demuxes again in userland, but it seems a
    bit of a shame to pick out all the PIDs in kernel, stick them back
    together in kernel, and send them to userland only to get unpicked
    again, when the alternative is such a small API addition.

    The attached patch adds a new value for dmx_output_t:
    DMX_OUT_TSDEMUX_TAP, which sends TS to the demux0 device. With this
    patch and a dvb-usb-dib0700 (and UK Freeview from Sandy Heath), I can
    successfully capture an audio/video PID pair into a TS file that mplayer
    can play back.
