jp9000 fa7286f84c libobs: Shut down encoder when not in use
This prevents encoders (hardware encoders in particular) from being
continually active when all outputs disconnect from an encoder.  This is
mostly just a temporary measure; the encoding interface may need a bit
of a redesign.  It will also definitely needs to be able to flush at
some point.  Currently when an output is stopped, the pending data is
discarded, which needs to be fixed.

jp9000 af310fb556 libobs: Allow object creation if id not found
Allows objects to be created regardless of whether the actual id exists
or not.  This is a precaution that preserves objects/settings if for
some reason the id was removed for whatever reason (plugin removed, or
hardware encoder that disappeared).  This was already added for sources,
but really needs to be added for other libobs objects as well: outputs,
encoders, services.

jp9000 df14671d2f libobs: Fix cmake bug (make sure variable exists)
If the FFMPEG_AVCODEC_LIBRARIES variable does not exist, it will
generate a cmake error, so check to make sure the variable exists before
executing this code.

jp9000 d78d0072a0 libobs/util: Add functions to inhibit sleep
These fucntions prevent the computer from going to sleep, hibernating,
or starting up a screen saver.

On linux, it will also attempt to use DBus to prevent gnome/kde/etc
sleep, but it's not necessarily required in order to compile the
library.  Otherwise, it will simply call "xdg-screensaver reset" once
every 30 seconds to reset the screensaver timer.

jp9000 5096b3c697 libobs: Set reconnect to false on user cancel
This fixes the issue when an output cancels reconnecting, reconnect is
left at true, causing obs_output_active to always return true even
though reconnecting has actually been canceled.

jp9000 0538865553 libobs: Add encoded output delay support
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.

Palana b2714fa353 libobs/util: Restore original code point
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

jp9000 ff6cf508e5 libobs/media-io: Improve audio data logging
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.

jp9000 263037102b libobs/media-io: Fix potential crash inserting audio
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.

jp9000 e479d4d0dc libobs: Add obs_data funcs for safe file handling
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.
2015-08-21 18:22:24 -07:00
jp9000 40988f7e1d libobs: Add obs_data_save_json function
We keep having to repeat code for saving the json data to a file, so add
a helper function to help clean up some of that code.

jp9000 dd9107dbd8 libobs: Don't return valid obs_data if json fails

return a valid data object; return NULL instead.

jp9000 3a77ac3516 libobs/util: Add os_quick_write_utf8_file_safe
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).

jp9000 0d30d1229f libobs: Add API func to get module config path
Allows the ability to get a module-specific configuration file/path
2015-08-19 12:16:21 -07:00
jp9000 2bd8ab7c09 (API Change) libobs: Add global module config path
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

jp9000 cd222f8ce0 libobs/util: Fix character encoding issue
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.

jp9000 6bd4f27fe9 libobs: Fix issue with getting the module data dir
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.

jp9000 d53cef47ac libobs: Add obs_data_create_from_json_file func
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)

Palana bf2df49d71 libobs: Prevent registering (potentially) unsupported plugins
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

Palana a26afbb9ae libobs: Prevent out of bound reads in obs_register_*

Palana 13b2469d61 libobs/util: Extend profiler csv export data
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

Palana 44b5afbd07 (API Change) libobs: Add profile_name_store_t parameter to obs_startup
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

jp9000 b89ea47b96 (API Change) libobs: Remove main window funcs/vars
(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.

jp9000 cf9f21e422 (API Change) libobs/graphics: Change gs_create param
(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.

see any non-compiling commits.

jp9000 0fb79a4733 libobs: Use get_win_ver (not GetVersionEx) 2015-08-01 14:51:22 -07:00
jp9000 ef332ab8b6 libobs: Add function to get the windows version
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)

Anthony Catel ffb3ca4595 libobs: Use one copy for RGBA output when possible
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.
