File contains data in an unknown format. (m4a load from librosa)
2 août 2022, par Moriyama AikoSo I am currently working on a DNN that takes in m4a files. I have ffmpeg, it creates a few batches and then dies on this error :

I am using this command


wav, sr = librosa.load(path, sr=16000)


is it just a broken file ? How do I skip such then ? Or is it something about loading a m4a file even with ffmpeg and the desired output when tested on a single m4a file ?

FFmpeg : encoding a PCM audio file to AAC using AAC codec info from another file
7 septembre 2022, par Siddharth KumarI have two audio files :


- 

audio_0.wav: PCM audioaudio_1.aac: encoded audio using some parameters






I'm trying to achieve the following outcome with FFmpeg :


Create a new file
audio_2.aacwhich contains audio fromaudio_0.wavencoded using the codec parameters fromaudio_1.aac.

If I run the following :

ffmpeg -i audio_0.wav -i audio_1.aac -c copy audio_2.aacthen I get streams from both muxed together.
I do not want content fromaudio1.aac. Any pointers to solve this would be appreciated.
