FFmpeg for Unity

Hi, I am trying to add audio to a video by executing the following command:
-y -i C:\Users\NOWHERE\Desktop\2019BackupJDI\NikeJDIKids\Captures\MovieCapture_2021-09-17_18-40-03_1920x1080.mp4 -i C:/Users/NOWHERE/Desktop/2019BackupJDI/NikeJDIKids/Assets/Michael/Sounds/FinalGameSound.mp3 -c:v copy -c:a aac -map 0:v:0 -map 1:a:0 C:/Users/NOWHERE/Desktop/2019BackupJDI/NikeJDIKids/Assetsugc_9171840.mp4

but I get the error:

InvalidOperationException: Cannot start process because a file name has not been provided. System.Diagnostics.Process.start() at <...........>

 

Please inspect what is the code behind "Add Sound" demo.
And do the same.

Good luck with a project!
Cheers!

 

hello, i am trying to mix Video with Audio by using

Code (CSharp):

1. -y -i test.mov -i test.wav -filter_complex [0][1]amix=inputs=2[a] -map 0:v -map [a] -c:v copy  -result

it is working fine, im getting the expected result however i want to know when does the command end to call another function how is that possible?

 

Good job!
You can path callbacks to main interface method:

Code (CSharp):

1. public static FFmpegProcess Execute(string command, List<IFFmpegCallbacksHandler> callbacksHandlers)

So when your job is done - you can start next one from the beginning.
Good luck with a project!

 

Not sure how to use that
im currently in a script where i call the FFmpegCommand.cs to run the command

Code (CSharp):

1. FFmpegCommand.StartFfmpeg(command);
2.  

after that i need to delete old video and keep the Merged one, however i cant really tell when the command is done, because merging bigger video with audio would take more time.

 

Another question, what is best approach regarding the command used

1. 
   
   Code (CSharp):

   1. -y -i test.mov -i test.wav -filter_complex [0][1]amix=inputs=2[a] -map 0:v -map [a] -c:v copy  -result

1. 
   is there a better command ? i am trying to take first input as video and 2nd as audio then merge and get video output of both but i need to keep the output duration equal to first input

 

Are you sure you use FFmpeg Bind 2 from here?
https://assetstore.unity.com/packages/tools/video/ffmpeg-bind-2-187458

 

Post title is ffmpeg for unity so thats what i am using https://assetstore.unity.com/packages/tools/video/ffmpeg-for-unity-199811 , it is not possible to use ffmpegcommand more than once simultaneously?

 

I'm not sure about that asset.
This thread is about FFmpeg Bind 2.
https://assetstore.unity.com/packages/tools/video/ffmpeg-bind-2-187458

 

Why is set 1920×1080, the picture is still very vague

 

How to close rtsp stream? I tried to use stopfmpeg function, but it didn't work

 

May depend on your backend.
You can also try own encoding as an option.
Good luck with a project!

 

If you have any problems with this in your app - killing of thread can be the option to try.
Good luck with a project!

 

Good news:
FFmpeg Unity Bind 2 is Open Source now.
Everybody can use, update, fork or develop it further.
Good luck with projects!

 

I can't get this to build for iOS at all, should I assume support has ended for this now it's open source? I don't really know where to start with trying to get a build up and running, the errors are:

In __threading_support:
Variable has incomplete type '__libcpp_timespec_t' (aka 'timespec')
Calling '__convert_to_timespec<timespec>' with incomplete return type 'timespec'

in system_clock
Reference to unresolved using declaration twice.

 

Hi wayfarergames i just deleted folder libavutil and a get the build
but, i use just for convert video and works great!

hope this can't help
