gstwebrtc-1.0.lib is a library that is part of GStreamer, which Servo
relies upon for media playback. To my best knowledge, the build
environment setup instructions have been enough to allow other people to
build on Windows without encountering this error. The code that
instructs the build to include gstwebrtc-1.0.lib in the final link comes
from here:
https://gitlab.freedesktop.org/gstreamer/gstreamer-rs-sys/blob/f7034258cd87bcfc3e0f0444417eeb580b3f6ccf/gstreamer-webrtc-sys/build.rs#L20-71
One of these things is likely true about your environment:
* the named file is missing from the gstreamer installation
* the gstreamer environment variables do not match the installation
directory
* you have an unsupported version of gstreamer installed
You may want to try uninstalling GStreamer, installing 1.14.3, then
running `mach.bat clean` before building again.

Hi Josh
Does Rust has issues with building with IntelliJ and Rust Up installed?
I came across several Rust build errors and were able to lookup and fix
throughout with Github issues posted. But this one is driving me crazy
error: linking with `link.exe` failed: exit code: 1181
= note: LINK : fatal error LNK1181: cannot open input file
'gstwebrtc-1.0.lib'
The issue posted and fix posted points to
https://github.com/servo/servo/blob/master/appveyor.yml#L57 which appears to be
VS Specific for build or is that something I missing. PS I am building on Servo
media instead of Servo root so my cargo is in \media instead of \root

Josh,
Just one more clarification,
1. Is it necessary we define and initialize the values and duration
parameter that we are using inside SetValueCurveAtTime inside the struct
Param <https://github.com/JHBalaji/media/blob/master/audio/src/param.rs#L30>
?
We assume that this is not needed as the implementation works without doing
the same (values vector gets passed). But duration gets passed as
Tick(44100) if we set a startTime as 1.0s. (Which we assume is because of
tick?)
Thanks,
Akhilesh

Hi Josh,
I totally understand. We will try to fix it using the examples you have
provided for now. Anyways, we will be continuing with the project for our
final project so whenever you/your team can validate our implementation, it
would help us proceed if we don't fix the issue by then. Thank you for
doing the same.
Best,
Akhilesh

Hi Josh,
1. Yes we are working on the example and have it defined as follows:
https://github.com/JHBalaji/media/blob/master/examples/set_value_curve.rs
Can you tell us if the example we have defined is right? We have
written it
similar to the example you shared with us
<
https://developer.mozilla.org/en-US/docs/Web/API/AudioParam/setValueCurveAtTime
.
2. Our implementation of the SetValueCurveAtTime to this point is as
follows:
https://github.com/JHBalaji/media/blob/master/audio/src/param.rs#L419-L439
As you had mentioned earlier, can you/someone from your team verify if
our
function definition is right? (Specifically for the linear interpolation
part, that's where we think the mistake is but not sure how to change
it)
as we are getting a few errors while trying to run the example.
I cannot guarantee that anybody will review it before Monday, sorry. You
could try looking at an existing implementation in Firefox for reference:

Running with RUST_BACKTRACE=1 will show you the precise line that is
panicking. I suspect you are not dealing with the case where the
duration has been exceeded.
Cheers,
Josh
