If audio buffering is very high, the audio packets built up in the
interleaved buffer would be significantly before the first video packet,
causing the offset between the starting video/audio packet pairs to be
significantly off, leading to desync.
This issue was not spotted until recently because it only happens when
streaming/recording with same encoders while audio buffering is very
high.
When using a chain hook method (forward or reverse), it was unwisely
assumed that the previous hook in the chain would not overwrite new
hooks when it's called. When the game capture hook calls the previous
hook in the chain, certain other programs that hook (in this case,
rivatuner on-screen display) would overwrite the hook with older data
and erase the game capture hook, causing it to only capture the first
frame and then never capture again.
This patch ensures that the hook is always saved before calling the next
hook in the chain and then restored after the call returns. It also
preserves any new hooks that may be added on top of it at any point.
The source shouldn't be inserted into obs->data.first_audio_source until it's
fully initialized, or other threads will access source->control and
dereference an uninitialized pointer.
Bitrate limit warnings wouldn't be correctly shown if service settings
are changed but not yet saved before modifying the bitrates/settings.
It would use the currently active service settings instead of the
changed values.
This is a band-aid solution to be able to create temporary services
without logging them and keep them out of enumeration functions.
This is a band-aid solution -- 'master obs context lists' should not be
kept by the core. Logging of object creation/destruction should also be
controlled by the front-end instead of the core.
avformat_free_context() only frees the memory used by an AVFormatContext
but it does not close the opened media file. This causes a leaked file
descriptor every time a media source frees a demuxer. Using
avformat_close_input() instead frees the context and closes the media
file.
This option is an x264-specific feature that may generate additional
keyframes when a major visual change in the output is detected. This
functionality is undesirable for streaming because it can cause
keyframes to become inconsistent and unpredictable, which can negatively
affect viewer buffering.
This patch fixes a specific crash where if the user named a filter the
same name as an input source that already existed in the system, scene
item loading code could find the filter with the same name instead of
the source, and mistakenly use it as the scene item's source directly.
This would cause a crash when trying to render that filter as a regular
source.
Marking filters as private is a temporary and simple workaround to the
solution. Filters are currently not meant to be found via the main
enumeration/search functions, which is a design flaw (lack of
consistency). In future major API revisions of libobs, filters should
be reworked to act as sources, with the sources they filter as
sub-sources ideally.
Additionally, the concept of "private context objects" and "primary
lists of context objects" in the back-end should probably also be
removed, allowing the font-end (or optional separate API layers) to
control all primary lists of obs context objects. These minor issues
that occur ultimately stem from API design flaws which need to be
corrected.
This crash happened when a filter was mistakenly used as a regular
source due to an unrelated bug in filter code and scene loading code.
The filter and the source it belongs to both had the same names, and the
source loading code found the filter and mistakenly used it as the
source instead of the actual source with the same name.
Fixes warnings with deprecated packet functions (av_free_packet and
av_dup packet, which were replaced by av_packet_unref and av_packet_ref
respectively)
This is to work around a Mesa issue that prevents copying
between RGB and RGBA textures. Other drivers seem to allow
this, even though it's technically not allowed by the GL
spec.
Closesjp9000/obs-studio#514
Determines whether an obs object was created successfully. If a plugin
that's used for a saved object is removed (third party plugins), its
data will become invalid, but the objects can often still be created for
the sake of preserving user settings, but sometimes these objects can
cause problems if they're actually used (such as using them for
transitions).
(Note: This commit also modified text-freetype2)
Prevents issues from being able to update files that may not be using
the current system encoding on windows.
Useful for two purposes:
1.) When many devices are hooked up to the system and used in separate
scenes, but only one device active at once is desired
2.) Allows users who are dependent on outputting audio to desktop to
disable that audio (via disabling that device) when the device isn't
being displayed
