  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.

  Convert pcm_s16le audio to mp3 (in php with ffmpeg/sox/...)? - Loïc Newest 'ffmpeg' Questions - Stack Overflow
  I have a bin and a cue file (CD image) and I am making a website to be able to listen to my music. I managed to split the tracks and make a (44 bytes) wav header so my browser can read the audio but the wav files are too big to be read on an unstable connection (it's 1411kbps where an mp3 would be 320kbps or lower!). At first, is there a way to convert the audio to mp3 without making a temporary file in php? Maybe ffmpeg or sox could help? Secondly, I would like to be able to satisfy partial content requests (so I can skip without loading the whole file). I have already (...)

  ffmpeg throwing "errorMessage": "spawn ffmpeg ENOENT" - ian Newest 'ffmpeg' Questions - Stack Overflow
  My ffmpeg function thats running as a shell command isnt working. I think its because 'ffmpeg' isnt really referring to anything. I have the ffmpeg node module in my bundle, but i dont know the execFile command is referring to it here. Im following aws-lambda-ffmpeg as an example of how to call this particular function.

I want to know how to replace 'ffmpeg' with something that will just recognize it (...) -- aws-lambda-ffmpeg, John Vansickle's static FFMPEG builds

  ffmpeg use shell script to make video from multiple images and one audio with specific timestamps for each image [closed] - Trojosh Newest 'ffmpeg' Questions - Stack Overflow
  I have an audio file and I have 15 images. I would like to make a video from these 15 still images. Each image may appear for different number of seconds. E.g. Image 1,2,3 will take 3 seconds each but image 4 may take 40 seconds because it is more complex. How can I use a shell script that uses ffmpeg to specify timestamp for each image and add audio to the same. Also note that the sum of timestamps of all images = running time of the audio. I looked at this question and image2 filter option from the official documentation but no luck in producing such a (...) -- image2 filter option
