La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.

Convert swf file to mp4 file using FFMPEG [migrated]
24 septembre 2012, par user1624004I now want to show an html5 video on a html page.
Now I have an sample.swf file, I want to convert it to .mp4 or .ogg or .webm file.
I have tried :
ffmpeg -i sample.swf sample.mp4But I got this error :
[swf @ 0000000001feef40] Could not find codec parameters for stream 0 (Audio: pcm_s16le, 5512 Hz, 1 channels, 88 kb/s): unspecified sample format

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.

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 ?
