video frames or 'valid' chunks of video).Īdditionnaly, I cannot find a lot of information about the image2pipe format but what I found is that this is only an input format, which expects to find data from multiple image files concatenated in the input stream. The way it is split in chunks depends mostly on the OS data buffering configuration (and possibly also both on how ffmpeg writes its output and on nodejs streams implementation), so chunk boundaries will most likely not be related to the actual data contents (ie. pipe(), you get the same data that would be written to a single output file, except it never ends up being written to the filesystem.

The code successfully runs the first time, creating an mp3 file, but after the 2nd time, it throws an error instead of appending it to the existing mp3 file. I tried take chunks of an audio file and directly convert them into an mp3 and append them to an mp3 file. mp3 file because of the wait time for large audio files. I am trying to avoid saving a very large audio file to disk and then formatting it to an. I was uploading an audio stream (.webm) to node which is accepted as an array of buffers.
