ffmpepg is not closed(killed) properly when I record the video and audio #104

Closed Rajagopalan-M closed 1 year ago

Rajagopalan-M commented 1 year ago

When the program uses 'recorder.close' to close the recorder, this error is thrown

2023-07-30 11:00:34 ScreenRecorder - ERROR - ffmpeg failed to stop. Force killing it...
2023-07-30 11:00:34 ScreenRecorder - ERROR - Forcefully killed ffmpeg. Recording failed!

I employed the subsequent syntax to capture both the video and audio

     advanced = { log: 'AppData/Logs/recorder.log', f: 'dshow', i: 'audio="virtual-audio-capturer"' }
                ScreenRecorder.ffmpeg_binary = File.expand_path("VideoRecorder/ffmpeg.exe")
                FFMPEG.ffprobe_binary = File.expand_path("VideoRecorder/ffprobe.exe")

recorder = ScreenRecorder::Desktop.new(output: File.expand_path("Output/Video/#{scenario}/#{testcase.first + '_' + testcase[2]}.mp4"), advanced: advanced)

However, when I record only the video using the following syntax, this error is not thrown.

    advanced = {
                  log: 'AppData/Logs/recorder.log'
                }

                  recorder = ScreenRecorder::Desktop.new(output: File.expand_path("Output/Video/#{scenario}/#{testcase.first + '_' + testcase[2]}.mp4"), advanced: advanced)

video log is here
