  How to send Ctrl+C to boost::process? - Mike Newest 'ffmpeg' Questions - Stack Overflow
  I launch FFmpeg in boost::process and get data from it every n seconds. If I terminate the app or FFmpeg in the console using Ctrl+C, FFmpeg flushes all data it has to stdout. But, if I terminate boost::process using the terminate() function, I don't get any data flushed. So I need to send Ctrl+C signal to the process before terminating it to get flushed data from FFmpeg. I tried: GenerateConsoleCtrlEvent(CTRL_C_EVENT, c.id()) But, it seems to have no (...)

  How can I render frames decoded by FFmpeg using hardware decoding with D3D11? - mercuric taylor Newest 'ffmpeg' Questions - Stack Overflow
  I have completed the process of decoding a video frame using FFmpeg. The format of the decoded frame is AV_PIX_FMT_NV12. Now, I want to render this frame to the screen using D3D11. My questions are: What is the equivalent concept in D3D11 for a decoded frame? Is it a texture? I have seen many solutions that convert NV12 data to RGB, but it seems that DX11 does not require this conversion anymore. I just want to display this frame, and since my frame is on the GPU, is there a more convenient way to render directly on the GPU without copying? Please forgive my (...) -- https://github.com/balapradeepswork/D3D11NV12Rendering/tree/master/D3D11NV12Rendering

  ffmpeg copies and restreams HLS/TS stream to RTP/Janus but fails on HLS/fMP4 stream - puterboy Newest 'ffmpeg' Questions - Stack Overflow
  I am using go2rtc to generate HLS streams to stream video from a PiCamera v3 running on an RPi5 for use in Octoprint. I also need to copy and restream the HLS stream to an RTP Janus server for Spaghetti detection. ffmpeg works fine on an HLS/TS (H264) stream but fails on a similar HLS/fMP4 (H264, H265, AAC) stream -- however, for quality reasons, I would prefer to use an HLS/fMP4 stream. Specifically, I am running the following: ffmpeg -re -i -an -c:v copy -an -f rtp rtp://127.0.0.1:17732?pkt_size=1300``` It streams properly forever when STREAM_URL is in (...)
