  • How to merge segmented webvtt subtitle files and output a single file ?

    15 février, par Dobbelina

    How to merge a segmented webvtt subtitle file and output a single file ?,
m3u8 looks like this example :

    



    #EXTM3U
#EXT-X-VERSION:4
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-MEDIA-SEQUENCE:1
#EXT-X-INDEPENDENT-SEGMENTS

    I noticed that each segment is not synchronized/cued against total playing time, but against the individual ts segments.
If ffmpeg could be used to do this, what magic input do i need to give it ?

    



    A single correctly cued vtt or srt file is what i want.

    



    I have a great appetite and don't like chunks, lol !

    



    Thanks for any replies you lovely people !

    



    



    With this i get a merged vtt file, but the cues are all wrong :

    



    ffmpeg -i "https://cmoreseusphlsvod60.akamaized.net/vod/bea44/0ghzi1b2cz5(11792107_ISMUSP).ism/0ghzi1b2cz5(11792107_ISMUSP)-textstream_swe=2000.m3u8" -f segment -segment_time 4 -segment_format webvtt -scodec copy out-%05d.vtt


    



    Each segment is not synchronized/cued against total playing time, but against the individual ts segments.
Example output of above command :

    



    WEBVTT

00:00.000 --> 00:03.040
Du har aktier i ett företag
som saknar framtid.

00:00.000 --> 00:03.280
De vill ha aktierna.
Du känner dem inte, Olga.

00:00.000 --> 00:01.720
De som får Kastrups aktier vinner.


    



    Cues all start like this which isn't very helpfull : 00:00.000

    



    Some segments contains no cues, like segment 15 for example :
https://cmoreseusphlsvod60.akamaized.net/vod/bea44/0ghzi1b2cz5(11792107_ISMUSP).ism/0ghzi1b2cz5(11792107_ISMUSP)-textstream_swe=2000-15.webvtt

    



    


    "A WebVTT Segment MAY contain no cues ; this indicates that no
 subtitles are to be displayed during that period."

    


    


  • Where to find old ffmpeg/ffprobe documentation ?

    5 mars 2019, par Multihunter

    There are several different versions of ffmpeg and ffprobe flying around, and each version has a different API.

    If I apt-get install ffmpeg on Ubuntu 16.04, I get ffmpeg version 2.8.15-0ubuntu0.16.04.1. If I install apt-get install ffmpeg on Ubuntu 18.04, I get version 3.4.4-0ubuntu0.18.04.1.

    When I visit the ffmpeg documentation, it says "The following documentation is regenerated nightly, and corresponds to the newest FFmpeg revision. Consult your locally installed documentation for older versions." That is, the hosted documentation is neither of those two versions.

    So I have two questions :

    • What does it mean "your locally installed documentation" ? Is it only talking about man ffmpeg ? Or is there some way to host the documentation as a webpage ?
    • Are there any places that simply host the older versions of the ffmpeg documentation ?

  • ffmpeg split audio and silences in a files, and replace the silences by custom silences

    16 mars 2019, par fireDevelop.com

    I have hundreds of podcast without music, just the voice and the room silence.
    In the silences, I have many clicks, respirations, etc...
    I need to clean all silences with a script, keeping intact the voice.

    In this picture you can see my dirty silences

    And here the result I want in all my audios

    When I use some scripts of sox. I don`t get the result I spect because the voice is affected by the script, the room-silence disappear and some clic still in the silences.

    Then in order to keep intact the voice, I want to do this :

    1. Delete all the silences longer than 3 seconds.

    1. Split all the audio and silences with in a sequence numbers. ie. :

      • 001-Silence-2.0seconds.wav
      • 002-voice.wav
      • 003-Silence-0.25seconds.wav
      • 004-voice.wav
      • 005-Silence-0.75seconds.wav
      • 006-voice.wav
      • ...
      • ...

    1. Before, run the script I created manually many files with silences of diferents silences I will use :

      • myManuallySilence-0.25seconds.wav
      • myManuallySilence-0.50seconds.wav
      • myManuallySilence-0.75seconds.wav
      • myManuallySilence-0.1seconds.wav
      • myManuallySilence-1.25seconds.wav
      • ...
      • ...
      • myManuallySilence-2.50seconds.wav
      • myManuallySilence-2.75seconds.wav
      • myManuallySilence-3.0seconds.wav
    1. the script will check the dirty silences duration and replace by the files myManuallySilence-x.xseconds.wav
    1. merge all files in one wav file, with the original voice and all the silences cleanned.

    At the moment I have only this script :

        # First denoise audio
    

    
## Get noise sample
    
ffmpeg -i in.wav -vn -ss 00:00:00 -t 00:00:01 noise-sample.wav
    

    
## Create noise profile
    
sox noise-sample.wav -n noiseprof noise.prof
    

    
## Clean audio from noise
    
sox in.wav clean.wav noisered noise.prof 0.21
    

    

    
# Split audio by noise
    
sox -V3 clean.wav output.wav silence 1 0.2 0.4% 1 0.2 0.4% : newfile : restart
    

    
####### (these settings worked for my computer mic - maybe we need to finetune them later) #######

    Is getting all the voice in separate files like this :
    output001.wav
    output002.wav
    output003.wav
    output004.wav
    ...
    output00x.wav

    Please, any suggestion will be appreciated.
    Thanks so much in advance !
