Apparently, despite the fact that Apple added
kAudioHardwarePropertyTranslateUIDToDevice in 10.8, it's not actually
usable in 10.8, only 10.9. So, instead of being able to use it like a
normal, sane person, we have to enumerate all devices manually and find
the AudioDeviceID ourselves. A slight annoyance and a mark against
apple's competence, but audio devices should now be working again on
10.8 at least, so whatever.
The biggest problem with DirectShow is that available configuration
capabilities can change if you so much as look at it the wrong way.
Previously, configuring devices often didn't configure the device
settings correctly, you would choose one setting and then another
setting wouldn't be compatible with that settings.
Let's take the terrible microsoft lifecam series for example. First,
you'd be at 640x480 happily webcam'ing away, which is using the YUY2
format. Then you decide "hey, this webcam resolution is a bit low. I
would love to have it a bit high resolution so it's a bit more crisp and
clear." You'd select 1280x720, and then suddenly the only format
supported is MJPEG output. However, the interface has to update that
fact, it can't list YUY2 if MJPEG is the only one available for this
resolution. This doesn't just apply to formats either, this applies to
framerates and such as well. Some framerates will only be supported by
certain resolutions which can in turn only be supported by certain
formats.
This causes user interface for configuration to be really be a nightmare
to manage if you want these features to be available to the user. It's
extremely annoying because you have to update all the configuration UI
after something has changed, double check the configuration values, and
if the values aren't supported, update those configuration values.
This covers the basics of devices. Mostly functional but not at 100%
yet. Uses 'libdshowcapture' library to capture directshow video/audio.
Both libdshowcapture and the plugin still need some work. Should at
least capture basic webcams and capture cards for the time being.
Character conversion functions did not previously ask for a maximum
buffer size for their 'dst' parameter, it's unsafe to assume some given
destination buffer may have enough size to accommodate a conversion.
This doesn't add FLV file output to the user interface yet, but we'll
get around to that eventually. This just adds an FLV output type.
Also, removed ftello/fseeko because off_t is a really annoying data
type, and I'd rather have a firm int64_t for large sizes, so I named it
to os_fseeki64 and os_ftelli64 instead, and changed the file size
function to return an int64_t.
This patch adds support for multi-screen setups by using xinerama
information if available to determine the screen size and position.
In case xinerama is not available or not active it uses the information
provided for the x screen.
To clean up the code some generic helper functions were moved to a
separate source file.
- Add volume control
These volume controls are basically nothing more than sliders. They
look terrible and hopefully will be as temporary as they are
terrible.
- Allow saving of specific non-user sources via obs_load_source and
obs_save_source functions.
- Save data of desktop/mic audio sources (sync data, volume data, etc),
and load the data on startup.
- Make it so that a scene is created by default if first time using the
application. On certain operating systems where supported, a default
capture will be created. Desktop capture on mac, particularly. Not
sure what to do about windows because monitor capture on windows 7 is
completely terrible and is bad to start users off with.
