Creating animated AVIF with FFmpeg
17 septembre 2022, par Ollie WilliamsEdit : This did eventually complete, and the output file is fine. I am using a top-end MacBook M1 Pro computer. Is it normal for it to be this relentlessly slow ? It was


My input file is an
.mov. I used this command :

ffmpeg -i Jellyfish.mov Jellyfish.avif

I also tried converting an MP4/h264 file.
In both cases it took over 50 minutes.


It's a 5 second long clip but it has taken about 20 minutes and the output file is still zero bytes.


This is the output in my terminal :

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 ?

lavc/mediacodecdec_common : enable refcounting of buffers unconditionally
18 septembre 2022, par sfan5lavc/mediacodecdec_common : enable refcounting of buffers unconditionally
This allows av_mediacodec_release_buffer to be called safely after
the decoder is closed, this was already the case with delay_flush=1.
Note that this causes holding onto frames to keep the decoding context
alive which is generally considered to be the intended behavior.Signed-off-by : sfan5 <sfan5@live.de>
