Instead of having ffmpeg-mux stored in a data directory, install it to
the primary binary directory. On windows, this fixes ffmpeg-mux
potentially accessing the wrong FFmpeg libraries (some programs install
them to system32, foolishly), and instead ensures that it uses the ones
that come with the program. On Linux, ensures that a binary is in its
appropriate directory (/usr/bin or /usr/local/bin rather than a subset
of /usr/share or /usr/local/share).
The quadro P5000 would incorrectly be considered blacklisted because it
used a string search for the P500, which is an earlier quadro variant
that does not have NVENC support.
To fix this, instead of just doing a string search, additionally check
to make sure that there preceding or trailing numbers on the adapter
name.
As per mantis issue 1403, the current wording for ClearOnMediaEnd is
ambiguous. Since it says "Hide source", some may believe it to mean the
scene item in the sources list will have it's visibility set to hidden.
This wording makes it clearer what the checkbox actually does.
According to nvidia's documentation using b-frames as reference results in
a slight quality improvement with no/negligible performance impact and is
recommended to be enabled by default when using multiple b-frames.
Because the new NVENC implementation requires texture sharing, if the
user chooses to use a secondary GPU, fall back to the old implementation
instead.
Adds a texture-based NVENC implementation which passes OBS NV12 output
textures directly to NVENC without downloading them off of the GPU,
increasing NVENC performance by a significant margin.
If NV12 textures are unavailable or the new encoder fails to initialize
for whatever reason, it will fall back to the FFmpeg NVENC
implementation safely.
Adds VBR rate control mode, adds a lookahead option, adds psycho visual
tuning option, removes level property (now always set to 'auto'),
removes "2pass" option (replaced by new "Max Quality" preset which uses
2pass by default), modifies a few defaults, and updates their locale
text.
This implements a blacklist of devices that ship with NVENC libraries,
but do not support NVENC, which would cause the plugin to mistakenly
think that NVENC was available when it was not. If these devices are
the only NVIDIA devices on the system, consider NVENC unavailable.
This is much more efficient than spawning an encoder on startup to see
if NVENC is available, which would incur a ~500 millisecond hit on
startup. Additionally, also much less crash-prone.
A bit of a hack, but this is one of the more common errors that users
are encountering, so showing useful information will help cut down on
the number of support issues.
Input buffer by default is set to 2MB - for some sources, for example streaming
RTSP input over UDP, this is not enough and causes significant playback issues
that are not present while playing back the same source under ffplay/mpv.
It looks like someone actually started working on this feature as there are
translated strings, properties and everything ready - only the control was
missing from the UI. This commit adds that control.
Currently, the range is set to 1-16MB, step 1MB. This is somewhat arbitrary,
so suggestions to tweak this range with more real-world use cases are welcome.
