@Kation

Is that build parameter at VisioForge.MediaFramework.Classes.DSFFMPEGEXEOutputBase.BuildVideoCodecParams ?

Can I get pdb file to breakpoint?

VisioForge

@visioforge

Yes, should be correct

@Kation OnFFMPEGInfo event can show you command sent to FFMPEG

Please show me your command line

We never tested it with nginx, but it's worked with YouTube and Wowza

Kation L

@Kation

@visioforge command line is : -y -loglevel error -hide_banner -rtbufsize 50M -f dshow -video_size 1920x1080 -framerate 25.000 -i video="VisioForge Network Source Video":audio="VisioForge Network Streamer Audio Source" -vf "scale = 1920:1080" -pix_fmt nv12 -c:v h264_mf -rate_control 3 -scenario 4 -quality 23 -c:a aac -b:a 128k -f flv "rtmp://127.0.0.1/live/demo"

When I use vfffmpeg64 to run it. It show

Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

Too

vfffmpeg64 -rtbufsize 50M -re -i "demo.mp4" -vf "scale = 1920:1080" -pix_fmt nv12 -c:v h264_mf -rate_control 3 -scenario 4 -quality 23 -c:a aac -b:a 128k -f flv "rtmp://127.0.0.1/live/demo"

This command run without error

@Kation

I think there is something wrong with DirectShow?

Kation L

@Kation

Or nuget package version is not newest?

Kation L

@Kation

@visioforge Any idea?

VisioForge

@visioforge

@Kation do you have 1920x1080 source?

Kation L

@Kation

yes

My test project contains a mp4 file. It is 1920x1080

Have you run my project successfully?

Kation L

@Kation

@visioforge When I start program, I use ffmpeg to capture dshow source and save to file

vfffmpeg64 -f dshow -i video="VisioForge Network Source Video":audio="VisioForge Network Streamer Audio Source" out.mp4

It capture the video with this image all time

Kation L

@Kation

And if I use ffmpeg download from official and run

ffmpeg -y -loglevel error -hide_banner -rtbufsize 50M -f dshow -video_size 1920x1080 -framerate 25.000 -i video="VisioForge Network Source Video":audio="VisioForge Network Streamer Audio Source" -vf "scale = 1920:1080" -pix_fmt nv12 -c:v h264_nvenc -quality 23 -c:a aac -b:a 128k -f flv "rtmp://127.0.0.1/live/demo"

while start program

It can publish video to server but with issue image slow than audio more and more every time that I said before

Kation L

@Kation

I change a RTMP server also fail with Error while opening encoder for output stream #0:0

Kation L

@Kation

@visioforge I'm using Youtube for live streaming but fail too

Any idea?

Hi. I have the project running with the trial and there is no water mark. All i need to do is a basic screen capture video. Record, Pause, Stop. Do i need to buy the full version or what are the limitations of the trial?

Says a nag-screen must appear. I'm assuming this might be after a couple mins of the video or something?

VisioForge

@visioforge

@MacWazzy yes, you need to buy the full version. Trial logo may appear randomly and stop randomly after a few minutes.

Hello guys, I have been using the old version of VisioForge and now there is no using VisioForge.Types.OutputFormat and a lot of stuff I was using, can someone tell me how can I use the videoView tool to show my screen? I have made a screen recorder and the only thing I need is to be displayed in the VideoView tool.

SacredTravis

@SacredTravis

@visioforge

VisioForge

@visioforge

@SacredTravis please check screen capture demo code - https://github.com/visioforge/.Net-SDK-s-samples/tree/master/Video%20Capture%20SDK/WinForms/CSharp/Screen%20Capture

SacredTravis

@SacredTravis

@visioforge Does that work on the newest version?

VisioForge

@visioforge

@SacredTravis yes, that's official demo applications repository

SacredTravis

@SacredTravis

@visioforge is there a way with VisioForge to capture only one window and not the whole screen? I want the user to be able to choose a window to screen record.

VisioForge

@visioforge

@SacredTravis https://github.com/visioforge/.Net-SDK-s-samples/tree/master/Video%20Capture%20SDK/WinForms/CSharp/Main%20Demo - It's possible. In the Main Demo you can select a window using special UI. in code you can specify window HWND to capture.

SacredTravis

@SacredTravis

@visioforge I cant make it work, I try to make the Videoview display what is being recorded but no luck :/

VisioForge

@visioforge

@SacredTravis With Main Demo and window capture or with Screen Capture demo and desktop capture? Screen Capture demo worked on your side?

SacredTravis

@SacredTravis

@visioforge those does not work in the newest version, those are for 15.3.4 and some code does not work like "VideoCapture1.OnError += VideoCapture1_OnError;"

VisioForge

@visioforge

@SacredTravis I've cloned the latest version and run demo (Net 5), all worked correctly. SDK v15.3.41, not v15.3.4. Why did the OnError event code not worked? What do you mean?

Maybe better to contact us using support@visioforge.com and send us full logs or create a remote session in AnyDesk?

SacredTravis

@SacredTravis

@visioforge this is the error

VisioForge

@visioforge

@SacredTravis please clone the latest samples repository, I've checked that all worked correctly
