Convert audio files to mp3 using ffmpeg [closed]
5 août, par Hrishikesh -Rishi- ChoudhariI need to convert audio files to mp3 using ffmpeg.



When I write the command as
ffmpeg -i audio.ogg -acodec mp3 newfile.mp3
, I get the error :

I also ran this command :



ffmpeg -formats | grep mp3




and got this in response :

I guess that the mp3 codec isn't installed. Am I on the right track here ?

finding speed and tone of speech in an audio using python
1er février 2018, par kRazzy RGiven an audio , I want to calculate the pace of the speech. i.e how fast or slow is it.
Currently I am doing the following :
convert speech to text and obtaining a transcript (using a free tool).
count number of words in transcript.
calculate length or duration of file.
finally,
pace = (number of words in transcript / duration of file)
.However the accuracy of the pace obtained is dependent purely on transcription , which I think is an unnecessary step.
Is there any python-library/sox/ffmpeg way that will enable me to
- to calculate, in a straightforward way,the speed/pace of talk in an audio
- dominant Pitches/tones of that audio ?

ffmpeg usage to encode a video to H264 codec format
2 avril 2024, par goldenmeanI have a *.mp4 video file(MPEG4 video codec) and I am trying to convert this to a H264 video codec format(raw h.264 format) using ffmpeg on Linux(Version - FFmpeg version SVN-r0.5.1-4:0.5.1-1ubuntu1, Copyright (c) 2000-2009 Fabrice Bellard,) using command line as shown below,



ffmpeg -i input .mp4 output.h264 




but I get an error saying -



Unsupported codec for output stream #0.0




Then when i try this option :



ffmpeg -i input .mp4 -formats h264 output.h264 




it still does not work, and gives -



Seems stream 0 codec frame rate differs from container frame rate: 59.94 (5994/100) -> 29.97 (30000/1001)
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Rapture.mp4':
 Duration: 00:02:06.44, start: 0.000000, bitrate: 26574 kb/s
 Stream #0.0(eng): Video: h264, yuv420p, 1920x1080, 29.97 tbr, 29.97 tbn, 59.94 tbc
 Stream #0.1(eng): Audio: aac, 48000 Hz, stereo, s16




And then it prints out help on the formats which we get when we do
ffmpeg -formats



When I checked the help,
ffmpeg -formats
, I see below information related to H264 file format and codec :


File format : 

DE h264 raw H.264 video format

Codecs:

D V D h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10




My questions :



- 

-
How can I convert the video to a H264 encoded video (raw H264 video format)
-
When I do
ffmpeg -formats
, I see many acronyms for the codecs supported, I see many acronyms before the codec name/type such as - D V D S E A, what do they stand for ? -
How to use the ffmpeg options
-vcodec
and-formats
?
