This reverts commit c3f4b0f018.
The obs_source_frame should not need to take flags to do this. This
shouldn't be a setting associated with the frame, but rather a setting
associated with the source itself. This was the wrong approach to
solving this particular problem.
Add 'flags' member variable to obs_source_frame structure.
The OBS_VIDEO_UNBUFFERED flags causes the video to play back as soon as
it's received (in the next frame playback), causing it to disregard the
timestamp value for the sake of video playback (however, note that the
video timestamp is still used for audio synchronization if audio is
present on the source as well).
This is partly a convenience feature, and partly a necessity for certain
plugins (such as the linux v4l plugin) where timestamp information for
the video frames can sometimes be unreliable.
Typedef pointers are unsafe. If you do:
typedef struct bla *bla_t;
then you cannot use it as a constant, such as: const bla_t, because
that constant will be to the pointer itself rather than to the
underlying data. I admit this was a fundamental mistake that must
be corrected.
All typedefs that were pointer types will now have their pointers
removed from the type itself, and the pointers will be used when they
are actually used as variables/parameters/returns instead.
This does not break ABI though, which is pretty nice.
This prevents certain issues I've encountered with devices where they
expect to shut down in a specific thread they started up in, as well as
a number of other issues, such as the configuration dialogs.
The configuration dialogs require that a message loop be present, and
this was not the case previously because everything was in the video
thread, which has no windows-specific code.
Configuration/crossbar/etc dialogs will now execute correctly.
This adds support for dynamic format changes on the fly. Format,
resolution, sample rate, can all now be changed by the current
directshow device on the fly.
On an asynchronous video source, the source resolution is automatically
handled by the core, and set to the resolution of the last video data
that was sent. There is no need to manually specify a resolution.
This implements audio support, allowing not only the ability to capture
the built-in audio from the video device's audio capture pin, but also
the ability to override the default audio with a custom audio device.
The DShowInput::Update function was split up and refactored a bit, as it
was getting a bit large and messy.
For the sake of consistency, renamed these two functions to include
_value at the end so they are consistent.
Renamed: To:
-------------------------------------------------------
obs_data_has_default obs_data_has_default_value
obs_data_has_autoselect obs_data_has_autoselect_value
obs_data_item_has_default obs_data_item_has_default_value
obs_data_item_has_autoselect obs_data_item_has_autoselect_value
This functionality can now be handled automatically because locale can
now be freed seaparately from obs_module_unload with
obs_module_free_locale, which is called automatically when the module is
being freed.
Autoselection is only implemented for frame rate as it doesn't make
sense to autoselect the video format (Any fills the role of library
supplied autoselection) or the resolution (it may make sense to
implement resolution matching based on the current transformation
settings in the future though)
