if rtmpStream function is like this... is possible to use RtmpCamera1 for the USB, should I pass the camera in RtmpCamera1.switchcamera(id) something like that ?? |

Hello, Your original post is not using CameraUvcSource, it is using Camera2Source. I'm not sure if a USB camera can work like that. |

Yes I am trying to use USB camera for live streaming... Everything works fine... the main problem I am facing is live streaming is lagging badly and also always streaming at 5Mbps, unable to change the video bit rate... |

That is weird. Are you sure that the bitrate value set to prepareVideo is correct? val rtmpStream: RtmpStream by lazy {
RtmpStream(requireContext(), Camera1Source(context), MicrophoneSource(), this).apply {
getGlInterface().autoHandleOrientation = true
getStreamClient().setBitrateExponentialFactor(0.5f)
getStreamClient().setAuthorization("mani","Pr1th1v1")
}
} |

I gave code like this, still the same problem... video bitrate is 5Mbps (I am sending you the screenshot while live streaming), actually it has to stream at 2Mbps (it is working fine in RtmpCamera1 prepareEncoder)... Same code only I am using in RtmpCamera1 also

I confirm there is some problem in the prepare Encoder, it is not changing the video bitrate, even in your sample application also I am facing the same issue. Here I am sending you the screenshot I gave private val vBitrate = 100 * 1000 like this but it streams at 5Mb

Hello, Are you using SurfaceView or TextureView with RtmpCamera1? |

In RtmpCamera1 I use OpenGlView |

If you are using SurfaceView or TextureView with RtmpCamera1 the encoder is configured buffer to buffer mode that is totally different that the surface to buffer used in the others cases. forceCodecType(CodecUtil.CodecType.SOFTWARE, CodecUtil.CodecType.FIRST_COMPATIBLE_FOUND) |

After updating the code, the bitrate is working fine now but still video is not smooth, it is lagging badly |

I tested with RtmpCamera1 Streaming and RtmpStream RtmpCamera1 is streaming superbly The Video Bitrate is fine, but quality is not good Both the streams I tried with both 1Mb and 2Mb, the result is same |

Instead of using SurfaceView, I used OpenGLView for USB Camera, it works fine, there is no lagging and video streaming is smooth. |

Hello, Can you share me the full code example using OpenGlView? Did you try without preview using the rotation app example? (Remove the startPreview line) |

Nothing big change... just used OpenGLView instead of SurfaceView, it worked fine import android.os.Bundle @RequiresApi(Build.VERSION_CODES.LOLLIPOP) companion object { val rtmpStream: RtmpStream by lazy { @SuppressLint("ClickableViewAccessibility") } fun setOrientationMode(isVertical: Boolean) { override fun onCreate(savedInstanceState: Bundle?) { private fun prepare() { override fun onDestroy() { override fun onConnectionStarted(url: String) { override fun onConnectionSuccess() { override fun onConnectionFailed(reason: String) { override fun onNewBitrate(bitrate: Long) { override fun onDisconnect() { override fun onAuthError() { override fun onAuthSuccess() { |

That code solved both? Bitrate and laggy? About the bad quality, did you try 8000 * 1000 using that resolution (1920x1080)? |

Yes it solved bitrate and lagging issue. I will try 8000 * 1000 using that resolution (1920x1080) and update you |

I tested in 8000 * 1000 video bitrate, there is a lag in the stream |

Do you mean delay or low fps? Log.e("Pedro", "Device: ${Build.MANUFACTURER} ${Build.MODEL}")
for (info in CodecUtil.showAllCodecsInfo()) {
Log.e("Pedro", info)
} |

Quality and lag issue: at 8000 x 1000 the video stops for 2 or 3 seconds and starts again (in Youtube) at that time, the image gets distorted |

Your case is normally related with a keyframe issue. You have 4 encoders of H264: 2 hardware and 2 software. Using my app with rotation example(replace surfaceview to openglview if you need). Go to this file: if (name.equalsIgnoreCase("c2.mtk.avc.encoder")) return false;
if (name.equalsIgnoreCase("c2.mtk.avc.encoder.secure")) return false;
if (name.equalsIgnoreCase("c2.android.avc.encoder")) return false;That code will skip that codecs and use the next available code. Remember test using your video config and in both cases, with force software encoder and without it. |

I need a help in prepareEncoders() function, whatever bitrate I pass, it is streaming at 5Mbps speed, in low internet situation the video is lagging very badly. By default iBitRate value will be 2 (for 2 Mbps streaming)...
The same logic is working perfectly for RtmpCamera1 here I am facing problem. Can any one help me
