  FPS reduction for H264 [closed] - Александр А Newest 'ffmpeg' Questions - Stack Overflow
  There is a USB camera that sends H264 frames with a frequency of 30 fps in a resolution of 1920x1080, GOP size 30 or 60 (1 or 2 I frame per second depending on the camera and only P-frames), which requires throughput of about 6 mbit/s. It is necessary to reduce this to no more than 2 mbit/s. All this is done on a weak ARMv7, so the option of transcoding is extremely resource intensive, especially considering that I did not find how to do it as a GPU Mali (NanoPi Neo Core). # ./ffmpeg -hide_banner -codecs | grep h264 DEV.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders: (...) -- as I understood from what was written here

  FFmpeg lavfutils.h seems to be missing - Collin Newest 'ffmpeg' Questions - Stack Overflow
  The lavfutils.h file is missing from the include folder where the ffmpeg library was put. I installed the ffmpeg library to load an image in c++. I installed it using ./vcpkg ffmpeg. The ff_load_image function is in lavfutils.h, but that file is missing from the ffmpeg_x64-windows folder where vcpkg put the rest of the library. Has the way you load images changed? Or have I installed ffmpeg incorrectly?

  I am working on a project to stream an H.264 video file using RabbitMQ (AMQP protocol) and display it in a web application. The setup involves capturing video frames, encoding them, sending them to RabbitMQ, and then consuming and decoding them on the web application side using Flask and Flask-SocketIO. However, I am encountering performance issues with the publishing and subscribing rates in RabbitMQ. I cannot seem to achieve more than 10 messages per second.
