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.mp4
But I got this error :

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.aac
which contains audio fromaudio_0.wav
encoded 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.aac
then 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 ?
