  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. They are referring to 'ffmpeg' as a 64-bit linux build they created from John Vansickle's static FFMPEG builds in their gulp 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

  SharedArrayBuffer is not defined & SyntheticBaseEvent - Dain Park Newest 'ffmpeg' Questions - Stack Overflow
  thank you for your help with my problem. I am using FFmpeg.wasm on Next.js to compress videos when users upload them. I then send the videos to a server and save them on AWS S3. For the client side, I'm using Next.js. To solve the error "SharedArrayBuffer is not defined", I added the following code to next.config.mjs: /** ⓐtype import('next').NextConfig */ const nextConfig = reactStrictMode: false, async headers() return [ source: '/(.*)', headers: [ key: 'Cross-Origin-Opener-Policy',  (...)

  ffmpeg Command in Docker with Rust Tokio Closes Warp Server Connection (curl 52 Error) - user762345 Newest 'ffmpeg' Questions - Stack Overflow
  I’m encountering an issue where executing an ffmpeg concatenation command through Rust’s Tokio process in a Docker container causes subsequent HTTP requests to fail. The error occurs exclusively after running the ffmpeg command and making immediate requests, resulting in a “curl 52 empty response from server” error with the connection being closed. Notably, this issue does not occur when running the same setup outside of Docker. Additionally, if no HTTP requests are made after the ffmpeg command, the curl 52 error does not occur. Here is the verbose curl output of my minimum reproducible (...)

  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 1.4MB/s!). 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 succeeded it for the wav files and I would (...)

  How to use the actual frame numbers in filenames using ffmpeg when extracting frames? [closed] - Joan Venge Newest 'ffmpeg' Questions - Stack Overflow
  Basically I am using ffmpeg to extract every Nth frame from a video. But the filenames appear sequentially from 1 to X. I want to use the actual frame numbers so if it's every 30th frame, then the filenames should be 0, 30, 60, etc. Is this possible? I am doing this in Python using this function: def extract_and_compress_frames(directory, frame_interval=1, crop_width=192, crop_height=108, offset_x=0, offset_y=0): for filename in os.listdir(directory): if filename.endswith(".trec"): # Construct full file path trec_path = os.path.join(directory, (...)
