This feature allows a user to delay an output (as long as the output
itself supports it). Needless to say this intended for live streams,
where users may want to delay their streams to prevent stream sniping,
cheating, and other such things.
The design this time was a bit more elaborate, but still simple in
design: the user can now schedule stops/starts without having to wait
for the stream itself to stop before being able to take any action.
Optionally, they can also forcibly stop stream (and delay) in case
something happens which they might not want to be streamed.
Additionally, a new option was added to preserve stream cutoff point on
disconnections/reconnections, so that if you get disconnected while
streaming, when it reconnects, it will reconnect right at the point
where it left off. This will probably be quite useful for a number of
applications in addition to regular delay, such as setting the delay to
1 second and then using this feature to minimize, for example, a
critical stream such as a tournament stream from getting any of its
stream data cut off. However, using this feature will of course cause
the stream data to buffer and increase delay (and memory usage) while
it's in the process of reconnecting.
This was broken in cd222f8ce0 which had a
horrible commit message that makes replicating the issue impossible if
there weren't others who reported similar visual studio issues when
using a Japanese locale
This improves logging for when audio data insertion is way out of bounds
or is getting cut off in the front due to a bad negative sync offset.
Instead of throwing out a log message for every time this happens with
each piece of data, it now states when the out of bounds or cutoff has
started and stopped only.
This fixes a case where an insertion of audio data would pass
valid_timestamp_range yet the insert position would cause a negative
integer position and thus an unsigned integer overflow.
obs_data_create_from_json_file_safe: Attempts to create an obs_data
object from a file, and if that fails and a backup file exists, deletes
the old file and tries to open it again.
obs_data_save_json_safe: Saves json data to a temporary file first,
optionally backs up the target file if the file exists and backup_ext is
valid (otherwise deletes it), and then renames the temporary file to the
target file. This helps reduce the chance of json corruption on save.
This helper function saves to a temporary file first, (optionally) backs
up the original file, then renames the temporary file to the actual file
name. This helps reduce the chance of file corruption under various
circumstances (such as shutdown or crash while the file is being written
to disk).
API Changed:
---------------------------
From:
- bool obs_startup(const char *locale, profiler_name_store_t *store);
To:
- bool obs_startup(const char *locale, const char *module_config_path,
profiler_name_store_t *store);
Summary:
---------------------------
This allows plugin modules to store plugin-specific configuration data
(rather than only allowing objects to store configuration data). This
will be useful for things like caching data, for example looking up and
storing ingests from remote (rather than storing locally), or caching
font data (so it doesn't have to build a font cache each time), among
other things.
Also adds a module-specific directory for the UI
Manually specifies the UTF-8 character codes used by the file rather
than relying on the compiler to determine what the codes are manually.
I was getting compile errors due to the fact that my current code page
is not at the default code page; so visual c++ tried to use my current
code page rather than UTF-8 and it would cause an error on the file.
When getting a blank module data file (indicating you want to get the
path to the module data directory itself), on certain operating systems
(windows) it will fail if you end the path with '/' or '\'. So simply
make sure that if a blank module sub-path is used, don't try to append a
slash.
Just a little helper function that allows you to create an obs_data_t
object from a json file (rather than having to manually open it each
time and then call obs_data_create_from_json on the file data)
The rationale for rejecting these register calls is that these functions
may be required for the plugin to work properly, which can't be
guaranteed when libobs doesn't know about them.
This behavior may be revisited once the plugin manager is implemented,
to e.g. make it configurable (potentially per plugin) to allow loading
newer plugins in case they are known to work with the older libobs
The id and parent_id fields should now allow better recovery of the
actual call trees, though they aren't compatible between different data
dumps in a single profiler session anymore; for that reason the new
fields name_id and parent_name_id are introduced, they hold the old id
and parent_id values respectively
Due to all the threads in libobs it wouldn't be safe to make that
parameter reconfigurable after libobs is initialized without adding
even more synchronization. On the other hand, adding a function to set
the name store before calling obs_startup would solve the problem of
passing a name store into libobs, but it can lead to more complicated
semantics for obs_get_profiler_name_store (e.g., should it always return
the current name store even if libobs isn't initialized until someone
calls set_name_store(NULL)? should obs_shutdown call
set_name_store(NULL)? Passing it as obs_startup parameter avoids
these (and hopefully other) potential misunderstandings
(Non-compiling commit: windowless-context branch)
API Changed:
---------------------
Removed functions:
- obs_add_draw_callback
- obs_remove_draw_callback
- obs_resize
- obs_preview_set_enabled
- obs_preview_enabled
Removed member variables from struct obs_video_info:
- window_width
- window_height
- window
Summary:
---------------------
Changes the core libobs API to not be dependent upon a main window/view.
If you wish to draw to a window/view, use an obs_display object to
handle it.
This allows the use of libobs without requiring a window to be present
on the system. This is also prunes code that had to be needlessly
duplicated to handle the "main" window.
(Non-compiling commit: windowless-context branch)
Changes API from:
---------------------
EXPORT int gs_create(graphics_t **graphics, const char *module,
const struct gs_init_data *data);
To:
---------------------
EXPORT int gs_create(graphics_t **graphics, const char *module,
uint32_t adapter);
Summary:
---------------------
Changes the gs_create function to use an adapter parameter instead of
requiring a gs_init_data with window/color/etc information.
Intentionally breaks compilation when trying to compile the specific
merged commits within the windowless-context branch. This is meant to
be used in conjunction with a merge commit so that bisecting will never
see any non-compiling commits.
Microsoft basically deprecated GetVersion/GetVersionEx, so now you have
to query the file version of kernel32.dll in order to get the actual
windows version. Because of the steps involved in getting the windows
version are fairly complicated, this is an exported libobs helper
function that can be used to get the windows version if needed.
(Microsoft does have its own set of helper functions for this but the
API feels a bit.. awkward, and you can't actually get the real windows
version with them)
A minor optimization: in copy_rgbx_frame (used when libobs is set to
output RGBA frames instead of YUV frames), if the line sizes for the
source and destination match, just use a single memcpy call for all of
the data instead of multiple memcpy calls.
Added cast to unsigned and the assert because microsoft's compiler
doesn't support "%zu"
Actual warning:
libobs/graphics/effect-parser.c:1387:4: warning: format specifies type
'unsigned int' but the argument has type 'size_t' (aka 'unsigned long')
[-Wformat]
Certain plugins/modules that are loaded on windows may be dependent on
libraries that are located in the same directory as the module in
question. This makes is so that LoadLibrary will also search for
dependent libraries for that module in the module's directory.
