  How to use ffmpeg to open 2 cams and push the stream from one of them? - kkk123 Newest 'ffmpeg' Questions - Stack Overflow
  I'm using ffmpeg to capture 2 cams and push stream from one of them. For single camera, I start capturing frames by calling startCameraCapture() from main() which calls initRemoteStream(). Here it opens a pipe to ffmpeg to initialize streaming. Followed by it, decodePacket() is called which writes YUV422 data to the pipe. It runs fine. But when I want to use 2 cameras, I create a thread for each camera in main() and define active_cam. When I want to push cam1's stream, active_cam = 1. The same logic of the single cam is used. It doesn't work. Could you please (...)

Each package is h264 encoded frame, wrapped with some relevant data. I need to write a code using Libav where I can: Feed the frames one by one using AVIOContext (or smth similar). Grab decoded frame. Draw that to a window (Not relevant to the question, writing for context). I've been doing the same with GStreamer by creating a pipeline like this: AppSrc -> H264Parser -> H264Decoder -> (...)

  FFPEG: Errors opening audio input stream on MacOs - Xavi Newest 'ffmpeg' Questions - Stack Overflow
  I am encountering the following warning (from Audio Toolbox?) very often when opening an external microphone audio stream with ffmpeg's libavformat on macOS: CMIO_Unit_Converter_Audio.cpp:590:RebuildAudioConverter AudioConverterSetProperty(dbca) failed (1886547824) This warning results on the codec id of the stream not being properly detected and it defaulting to the dummy AV_CODEC_ID_FIRST_AUDIO, which defaults to AV_CODEC_ID_PCM_S16LE, and results on distorted audio decoding the packet when this is not the correct codec. You can observe the error with the following (...) -- Audio Toolbox

I used ffmpeg to create a function that gets in input the path of the file, the position in time where to start to output the samples and the lenght of the chunk to decode in seconds. I have no reputation, so I had to make a gdrive directory where you can see the problem and the files on which I worked.
