Only warn when the pointer provided to obs_source_release() is
non-NULL. In some custom usages of libobs, libobs may be freed before
OBS* smart pointers (like OBSSource) are destructed, leading to a
misleading warning if the pointers have already been cleared with
nullptr.
Previous behavior is basically:
- Clear OBS* pointers with nullptr
- Unload libobs
- Those smart pointers that were cleared will still call
obs_source_release() on destruct
- Warning appears
Add comparison check so that NaN is caught.
Comparisons with NaN always result in false.
NaNs cause problems later in audio encoder.
Note: may break with -ffast-math compiler flag.
Fixes#4885.
Since [1], avcodec/version.h is not included anymore in codec.h and
therefore is not included any more in avformat.h.
As a result, LIBAVCODEC_VERSION_INT is no longer defined. This commit
fixes the include.
Since obviously we can't ifdef the avcodec include by referring to an
avcodec version, we ifdef it with the avformat version which was bumped
at the same time [2].

Prior to this change, the audio thread roughly waits the time of
`AUDIO_OUTPUT_FRAMES`, and consecutively processes twice or more if the
latency is accumulated. This behavior causes fluctuation of timing to
output audio packets. This change introduces `os_sleepto_ns_fast` so
that the audio packets will be periodically output.
The function `os_sleepto_ns` has a spin loop so it will consume CPU
resource. The new function has same interface but consumes less CPU
resource with a drawback of less precision.
Fixes studio mode preview on SDR monitor for HDR canvas rendering SDR
source into SDR swap chain. Needs to render SDR source into HDR render
target, and then tonemap into SDR swap chain for preview.
To simplify logic in source files, `LINUX_PORTABLE` is only defined
if the associated build flag is enabled. Thus straight-forward `ifdef`
checks suffice.
Details in #6226, basically this fixes an issue where OBS links
to the system-installed librtmp1, which is incompatible with our
librtmp.

Due to the way the frontend works, the logic for inserting the row for
the group in the UI was dropped since the new item_add message will
insert one automatically since it forces a refresh of the scene items.
The reliance on that implicit row insertion when grouping items is a
bit of a code smell, although the alternative would be to add logic to
disable handling the signal for that instant, which is probably a
worse choice.
Allows a frontend the ability to set the maximum audio buffering
latency, and specify whether that audio buffering is either fixed (to
the maximum audio buffering latency), or dynamically increasing from 0.
This will be useful if the user wishes to output audio to devices or
through a virtual audio device at a guaranteed minimal latency.
When audio buffering is maxed, certain sources will always repeat the
same debug logging message of "render audio source [name] has gone
backwards", which shouldn't apply if the audio timestamp is 0 rather
than a valid audio value.
This is in anticipation to adding low audio latency mode, will cause
audio buffering to be fixed rather than dynamically increasing. Having
fixed audio buffering means that audio latency always stays the same
rather than dynamically increasing.
Timestamp of some of audio sources desync over the time and audio glitch
is suspected to be caused when the difference between `timestamp` and
`next_audio_ts_min` exceeds TS_SMOOTHING_THRESHOLD.
When such condition happens, leave a log message to investigate the
glitch of the audio.
Defaulting to 1 means that it can't be differentiated between whether a
source really has 1 channel. Now, should a source not have any audio
(yet), this function makes it very clear that this is the case by
returning 0.
HLG output uses MovieLabs-recommended procedure.
- If peak luminance is greater than 1000, use maxRGB EETF to 1000.
- Otherwise, don't tonemap.
- Then use normal HLG conversion procedure with gamma 1.2 (1000 nits).
Rec. 2020 is really an SDR spec, but I think HDR10 made it okay to slap
PQ on it, call it an HDR spec. Rec. 2100 came along after and formally
allowed the use of PQ/HLG, so we should use 2100 instead.
Verbosity of stdout was previously hardcoded to INFO, while log viewer
and log files had correct verbosity. This makes the behavior of
--verbose make sense in all places.
