$ bitbake

Nothing to do.  Use 'bitbake world' to build everything, or run 'bitbake --help' for usage information.

$ bitbake world

NOTE: Resolving any missing task queue dependencies

ERROR: Nothing PROVIDES 'libav' (but /home/minimonk/src/yoctoProject/meta-raspberrypi/recipes-multimedia/omxplayer/omxplayer_git.bb DEPENDS on or otherwise requires it)

ERROR: libav was skipped: because it has a restricted license not whitelisted in LICENSE_FLAGS_WHITELIST

ERROR: Required build target 'omxplayer' has no buildable providers.

Missing or unbuildable dependency chain was: ['omxplayer', 'libav']

Summary: There were 2 ERROR messages shown, returning a non-zero exit code.

3.A. omxplayer

==============

omxplayer depends on libav which has a commercial license. So in order to be

able to compile omxplayer you will need to whiteflag the commercial license

adding to you local.conf:

LICENSE_FLAGS_WHITELIST = "commercial" 

$ bitbake --help

Usage: bitbake [options] [recipename/target recipe:do_task ...]

    Executes the specified task (default is 'build') for a given set of target recipes (.bb files).

    It is assumed there is a conf/bblayers.conf available in cwd or in BBPATH which

    will provide the layer, BBFILES and other configuration information.

Options:

  --version             show program's version number and exit

  -h, --help            show this help message and exit

  -b BUILDFILE, --buildfile=BUILDFILE

                        Execute tasks from a specific .bb recipe directly.

                        WARNING: Does not handle any dependencies from other

                        recipes.

  -k, --continue        Continue as much as possible after an error. While the

                        target that failed and anything depending on it cannot

                        be built, as much as possible will be built before

                        stopping.

  -a, --tryaltconfigs   Continue with builds by trying to use alternative

                        providers where possible.

  -f, --force           Force the specified targets/task to run (invalidating

                        any existing stamp file).

  -c CMD, --cmd=CMD     Specify the task to execute. The exact options

                        available depend on the metadata. Some examples might

                        be 'compile' or 'populate_sysroot' or 'listtasks' may

                        give a list of the tasks available.

  -C INVALIDATE_STAMP, --clear-stamp=INVALIDATE_STAMP

                        Invalidate the stamp for the specified task such as

                        'compile' and then run the default task for the

                        specified target(s).

  -r PREFILE, --read=PREFILE

                        Read the specified file before bitbake.conf.

  -R POSTFILE, --postread=POSTFILE

                        Read the specified file after bitbake.conf.

  -v, --verbose         Output more log message data to the terminal.

  -D, --debug           Increase the debug level. You can specify this more

                        than once.

  -n, --dry-run         Don't execute, just go through the motions.

  -S SIGNATURE_HANDLER, --dump-signatures=SIGNATURE_HANDLER

                        Dump out the signature construction information, with

                        no task execution. The SIGNATURE_HANDLER parameter is

                        passed to the handler. Two common values are none and

                        printdiff but the handler may define more/less. none

                        means only dump the signature, printdiff means compare

                        the dumped signature with the cached one.

  -p, --parse-only      Quit after parsing the BB recipes.

  -s, --show-versions   Show current and preferred versions of all recipes.

  -e, --environment     Show the global or per-recipe environment complete

                        with information about where variables were

                        set/changed.

  -g, --graphviz        Save dependency tree information for the specified

                        targets in the dot syntax.

  -I EXTRA_ASSUME_PROVIDED, --ignore-deps=EXTRA_ASSUME_PROVIDED

                        Assume these dependencies don't exist and are already

                        provided (equivalent to ASSUME_PROVIDED). Useful to

                        make dependency graphs more appealing

  -l DEBUG_DOMAINS, --log-domains=DEBUG_DOMAINS

                        Show debug logging for the specified logging domains

  -P, --profile         Profile the command and save reports.

  -u UI, --ui=UI        The user interface to use (e.g. knotty, hob, depexp).

  -t SERVERTYPE, --servertype=SERVERTYPE

                        Choose which server to use, process or xmlrpc.

  --token=XMLRPCTOKEN   Specify the connection token to be used when

                        connecting to a remote server.

  --revisions-changed   Set the exit code depending on whether upstream

                        floating revisions have changed or not.

  --server-only         Run bitbake without a UI, only starting a server

                        (cooker) process.

  -B BIND, --bind=BIND  The name/address for the bitbake server to bind to.

  --no-setscene         Do not run any setscene tasks. sstate will be ignored

                        and everything needed, built.

  --remote-server=REMOTE_SERVER

                        Connect to the specified server.

  -m, --kill-server     Terminate the remote server.

  --observe-only        Connect to a server as an observing-only client.

  --status-only         Check the status of the remote bitbake server.

  -w WRITEEVENTLOG, --write-log=WRITEEVENTLOG

                        Writes the event log of the build to a bitbake event

                        json file. Use '' (empty string) to assign the name

                        automatically.

Or whatever you like for speed, rotation, and frames-per-second. BUT, here's the thing, the Pi only supports a fixed number of SPI frequencies. So tweaking the number a little won't do anything. The kernel will round the number to the closest value. You will always get frequencies that are 250MHz divided by an even number. Here's the only SPI frequencies this kernel supports

15,625,000 (a.k.a 16000000 = 16 MHz)

17,857,142 (a.k.a. 18000000 = 18 MHz)

20,833,333 (a.k.a 21000000 = 21 MHz)

25,000,000 (= 25 MHz)

31,250,000 (a.k.a 32000000 = 32MHz)

41,666,666 (a.k.a 42000000 = 42MHz)

62,500,000 (a.k.a 62000000 = 62MHz) 

use videocore GPU command  to switch off or on HDMI service thus saving valuable watts :)

Switch on

“/opt/vc/bin/tvservice -p”

Switch off

“/opt/vc/bin/tvservice -o”
