  1. vc_image: Add plumbing for side-by-side YUV420 format

    popcornmix committed Jan 31, 2018
    So U and V have same pitch as Y, but V = U + pitch/2

  1. MMAL: Use calloc on some structures to make Valgrind happy

    6by9 authored and popcornmix committed Feb 5, 2018
    Valgrind complains that various bits of MMAL structures
    are used before initialised. They aren't, but are filled
    in by the VPU or kernel so are out of sight of Valgrind.
    
    Using calloc for a couple of structures has minimal overhead
    and shuts Valgrind up.

  1. Raspicam: Verbose does not need to be disabled when writing to stdout

    ledazul authored and popcornmix committed Jan 30, 2018
    When writing to stdout ("-o -") verbose mode was being cancelled
    due to an expected conflict.
    Verbose text actually goes to stderr, so there is no conflict,
    therefore remove the code that was disabling verbose mode.
  2. raspividyuv: Fix saving timestamps.

    6by9 authored and popcornmix committed Jan 31, 2018
    The copy/paste from raspivid was missing some bits, so
    fix it.

  1. Support for independant display configuration

    JamesH65 authored and popcornmix committed Sep 12, 2017
    Add config.txt entries for individual display transposition and
    mods to dispmanx to support it.
    
    Required (in a way) for new LCD displays that operate by default
    in portrait, where you need to rotate them, but not the HDMI
    output.
    
    Displays info structure now contains information to say what needs to be
    done to the orientation to make it landscape so display driver can
    tell dispmanx whether a transpose is required without configuration
    options needing to be set.
    
    Three new config.txt flags:
    display_lcd_rotate -specifies rotate of LCD only.
    display_hdmi_rotate - rotate of HDMI/composite only.
    extra_transpose_buffer - allocates an extra transpose buffer when of
    a display is required.
  2. vc_image_helper: Add YUV 16 bit formats to second header

    6by9 authored and popcornmix committed Jan 29, 2018
    Duplicated in vc_image.h and vc_image_helper.h :-(
  3. vc_image: Add VC_IMAGE_TF_U8 and V8 to the ANY_TFORMAT case

    6by9 authored and popcornmix committed Nov 13, 2017
    Thew case_VC_IMAGE_ANY_TFORMAT macro was missing VC_IMAGE_TF_U8
    and VC_IMAGE_TF_V8, so computing the pitch was failing.
    
    The case described in #433
    is fixed with this.
  4. Video encode: Add option to set number of droppable P frames

    6by9 authored and popcornmix committed Jan 9, 2018
    OMX_IndexParamBrcmDroppablePFrames allowed the codec to be set up
    to make every other P-frame droppable (ie not a refernce frame for
    any subsequent frames).
    Extend this with OMX_IndexParamBrcmDroppableRunLength/
    MMAL_PARAMETER_VIDEO_DROPPABLE_PFRAME_LENGTH to set the rate at which
    reference P frames will be inserted.

  5. mmal/ril: Add MMAL_PARAMETER_VIDEO_ENCODE_SEPARATE_NAL_BUFS

    6by9 authored and popcornmix committed Nov 13, 2017
    Adds MMAL_PARAMETER_VIDEO_ENCODE_SEPARATE_NAL_BUFS to map to
    OMX_IndexParamBrcmNALSSeparate.
    Also adds MMAL_BUFFER_HEADER_FLAG_NAL_END to map to
    OMX_BUFFERFLAG_ENDOFNAL.
  6. mmal_il: Add missing mappings for 8 bit Bayer encodings

    6by9 authored and popcornmix committed Nov 29, 2017
    Mappings were missing for MMAL_ENCODING_BAYER_SGRBG8,
    SGBRG8, and SRGGB8. Add them.
  7. gx_create_window error cleanup fix

    piense authored and popcornmix committed Jan 23, 2018
    In the event of an error the cleanup code for gx_create_window() was cleaning up things that hadn't happened and crashing.
  8. Verbose is not disabled when capture is streamed

    ledazul authored and 6by9 committed Jan 29, 2018
    Verbose was being disabled when a capture is sent to stdout, but verbose is sent to stderr, so there is no need to disable it.

  1. Install interface/peer headers.

    gamaral authored and popcornmix committed Apr 27, 2014
    Currently vc_vchi_dispmanx.h requires vc_vchi_dispmanx_common.h which is
    not distributed on install. This limits access to the ELEMENT_CHANGE_*
    defines.

  1. dtoverlay app: Report unknown parameters in help

    pelwell committed Dec 8, 2017
    dtoverlay and dtparam will now report the first unknown parameter and
    return an error.

  2. dtoverlay app: Keep overlay symbols private

    pelwell committed Dec 8, 2017
    As of 4.14, the kernel overlay merging includes any symbols defined
    by an overlay, which can cause clashes between overlays (and even
    within them in the case that an overlay deliberately adds a global
    symbol as a way of exporting it to other overlays).
    
    In future we may choose to make use of this mechanism as a nicer
    way of exporting symbols, but for now just delete all symbols before
    presenting the overlay to the kernel.

  3. host-apps/dtoverlay: don't install scripts in random location

    yann-morin-1998 authored and pelwell committed Mar 7, 2017
    Currently, we add a custom command that installs the dtoverlay pre/post
    scripts in ${CMAKE_BINARY_DIR}/../../bin
    
    However:
    
      - this points outside of the package directory; it even points two
        directories higher;
    
      - when doing cross-compilation, this is definitely not the place where
        the /bin directory really is;
    
      - the scripts are already properly installed without this code.
    
    Remove that code, it serves no purpose and breaks for cross-compilation.

  4. dtoverlay: Create "/aliases" node when needed

    pelwell committed Nov 29, 2017
    Attempting to add an alias currently fails if there is no
    existing "/aliases" node. Prevent an error by creating one
    as necessary.

  1. RaspiVid: Print message stating TC358743 drivers are unsupported (#437)

    6by9 committed Nov 3, 2017
    Support requests for the TC358743 are getting annoying, so
    state that the drivers are unsupported, and are there on an
    as-is basis.

    RaspiCamControl.c : Typo in digital gain
Commits on Oct 10, 2017
  1. Raspicam: Add manual controls for analog and digital gain.

    6by9 authored and popcornmix committed Oct 6, 2017
    Requires exposure mode to be left at "auto" (or at least not
    "off").
    Fixes the value of analog and digital gains independently,
    so eg fixing analog gain at x4.0 will still allow exposure
    and digital gain to vary.
  2. MMAL: Fix example_basic_2 to actually play video

    6by9 authored and popcornmix committed Sep 27, 2017
    example_basic_2 seemed to be broken. It tried to use
    ZERO_COPY but in an invalid way. It also never looked
    for format changed events off the decoder, so would
    just stop once the decoder issued those.
    
    It now correctly allocates pools so that it can use zero
    copy, and also acts on MMAL_EVENT_FORMAT_CHANGED events
    to reallocate the pools and hence proceed.
    
    Fixes #285
  3. .gitignore: Ignore typical output files

  1. tvservice: Avoid unmatched reference counting on attach/unplugged events

    popcornmix committed Sep 15, 2017
    Thanks to Phil for spotting the suspicious code.
    See: raspberrypi/firmware#875
  2. IL Camera: Add manual analog and digital gain controls.

    6by9 authored and popcornmix committed Aug 15, 2017
    With MMAL_PARAMETER_ANALOG_GAIN and MMAL_PARAMETER_DIGITAL_GAIN
    setting either numerator or denominator to 0 will retain auto
    operation, otherwise the tuner will adopt the specified gain
    where the hardware will allow.
    The AGC algorithm does NOT include a fixed digital gain,
    so a fixed digital gain with auto exposure and analog gain
    will typically result in over exposed images.
