Merge pull request #202 from fryshorts/v4l2-input
...
Add libv4l2 as dependency for the v4l2 plugin
2014-07-29 11:39:43 -07:00
892fdea83e
Remove macro to free locale
...
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.

Remove version parameter from obs_module_load
...
Replaced by obs_get_version() API
2014-07-27 17:29:10 -07:00

Improved Documentation and Logging for mmap functions in v4l2 plugin.
...
This adds some documentation to the mmap functions and also
improves the logging by bumping errors to LOG_ERROR.
2014-07-26 19:55:57 +02:00
276a97877b
Add const keyword to fixed lists in v4l2 plugin.
...
This should save a little bit of memory memory.
2014-07-26 19:29:08 +02:00
25f71fd71d
Improved Documentation and Logging for update in v4l2 plugin.
...
This adds some documentation to the update function and also
improves the logging by adding some info and bumping errors
to LOG_ERROR.
2014-07-26 19:29:08 +02:00
b88fe5078c
Remove the getwidth/getheight functions from v4l2 plugin.
...
Those functions are actually causing more problems than
helping out with the preview because the width/height is
updated immediately while the actual size of the frames
displayed changes later.
2014-07-26 19:29:08 +02:00
b629087513
Reorganized data struct and update function for v4l2 plugin.
...
Due to the plugin creating a thread to retrieve and output the
captured image data, care must taken to not modify data the
thread reads from the outside while the thread is running.
In previous revisions some settings accessed by the capture
thread were written to in the update function which could cause
image corruption and in the worst case crashes.
The members of the data struct are now split into two groups,
those that are used by the thread while it is running and must
not be changed from the outside, and those can be changed at any
time.

Add function to prepare frame structure to v4l2 plugin.
...
This adds a function to prepare the source_frame struct for use
with obs_source_output_video. Since all of the values except for
the timestamp and data pointers are known in before it makes
little sense to compute them over and over again.
Due to the fact that v4l2 uses a single continuous memory segment
for multi planar formats we can also precompute memory offsets for
the planes.

Fix handling of multiplanar pixelformats in v4l2 plugin.
...
The data provided by v4l2 for multiplanar formats is one
consecutive block that just needs to be splitted for obs.
2014-07-26 19:29:08 +02:00
a6bb42c367
Display emulated formats as such in v4l2 plugin.
...
Formats that are emulated by v4l2 are marked by appending
"(Emulated)" to them.
2014-07-26 19:29:08 +02:00
9a573bb456
Replace all system calls with there counterpart in libv4l2.
...
By using the wrapper functions supplied by libv4l2 we gain
support for formats not natively supported by obs.
The library intercepts certain system calls to transparently
enable recoding.
2014-07-26 19:29:08 +02:00
d6f65be966
Add libv4l2 as requirement for the v4l2 plugin.
...
In order to convert formats not natively supported by obs the
v4l2 userspace library is required. This patch adds a cmake
script to find the library.
2014-07-26 19:29:08 +02:00

Add 720x576 (DV-PAL) as another fallback v4l2 framesize

Move all data into the subdir it belongs to
...
Completely removes the build dir in favor of cmake based build layouting
2014-07-19 01:38:41 +02:00
87a527701a
Use default color space in v4l2 plugin
2014-07-16 23:42:55 +02:00
ba3c093156
Add fallback sizes and framerates to v4l2 plugin.
...
Until a proper fix is found to support devices that use stepwise
or continuous values for framesize and framerate this adds fixed
values that can be selected.
For devices that support discrete values those are still queried
and used.
2014-07-16 23:42:55 +02:00
27297e7009
Add more logging to v4l2 plugin.
...
This adds some mostly user focused logging statements.
2014-07-16 23:42:55 +02:00

Use macro for prefixing log messages in v4l2 plugin
2014-07-16 23:42:55 +02:00

Some minor code refactoring in v4l2 plugin
...
Small code changes to decrease indentation a little.

Add locale for modules
2014-07-11 17:29:00 -07:00

Fix infinite loop in v4l2 plugin
...
With no device present the capability callbacks would cause an
infinite loop.
2014-07-11 17:48:12 +02:00
0b4a259e56
Remove 'locale' parameter from all callbacks
...
The locale parameter was a mistake, because it puts extra needless
burden upon the module developer to have to handle this variable for
each and every single callback function. The parameter is being removed
in favor of a single centralized module callback function that
specifically updates locale information for a module only when needed.
2014-06-25 12:36:26 -07:00
74b4743bce
Remove 'locale' from properties
...
Having the value stored here is somewhat pointless, so this is one step
in fixing the locale handling. Locale should be handled by the modules
themselves with their own loaded locale lookup information.
2014-06-25 12:36:26 -07:00
32911f774c
v4l2 plugin properties
...
added ability to choose device, pixel format, resolution
and frame rate
2014-06-18 23:37:19 +04:00

Add initial implementation of a v4l2 capture plugin
...
This patch adds a plugin to capture video data from v4l2 devices under linux.
