  • How to disable non-1st Audio Streams/Tracks in FFmpeg for mp4 files

    16 décembre 2016, par Dipesh

    My end goal is to create a single FFmpeg command that will convert my h264.DTS.mkv files to a format that is compatible with my AppleTV, whilst preserving the original quality.

    I’m almost there, however I have not been able to figure out how to disable streams/tracks.

    So far I have got :

    ffmpeg -i FILE \
    
 -y -strict experimental \
    
 -map 0:0 -map 0:1 -map 0:1 -map 0:1 -map 0:2 \
    
 -c:0 copy -c:1 aac -ac:a 2 -c:2 ac3 -ac:a 6 -c:3 copy -c:4 mov_text \
    
 OUTPUT

    This produces an output file that looks like :

    1. H264 video track (enabled) [copied from original]
    2. AAC 2 channel audio track (enabled)
    3. AC3 6 channel audio track (enabled)
    4. DTS 6 channel audio track (enabled) [copied from original]
    5. subtitle track (enabled)

    The problem is I need it to look like :

    1. 1 H264 video track (copied from original) (enabled)
    2. 1 AAC 2 channel audio track (enabled)
    3. 1 AC3 6 channel audio track (disabled)
    4. 1 DTS 6 channel audio track (copied from original) (disabled)
    5. 1 subtitle track (enabled)

    Hence I need to know how I can disable the non-1st Audio Streams/Tracks.

    From what I have read, this is part of the track header atom at the location "tkhd.flags". But I have not been able to figure out how to set this via command line arguments.

    Any help would be greatly appreciated.

  • OpenShot export no sound [closed]

    25 juin 2021, par Oneiroi

    Version : openshot-2.5.1-6.fc34.noarch

    


    Imported mp4 file with audio track.

    


    Export to mp4 format, AAC audio, lacks audio track verified with ffmepg and VLC (audio track is absent in exported file).

    


    I have already tried :

    


      

    1. Right click video track, set Enable audio to ON (from auto).

      2. 


    2. Edit -> Preferences -> Preview, set output device from Default to specific
device

      3. 


    


    Verified imported clip has audio even by right click track -> Display -> show waveform

    


    How can I export to mp4 format, with audio ?

    


    At the moment presuming "simple" option I am not seeing, perhaps ?

    


    Thanks in advance.

    


  • Does not work -hls_playlist in ffmpeg in the -dash section

    18 mars 2019, par jidckii

    I will use this assembly ffmpeg
    https://hub.docker.com/r/jrottenberg/ffmpeg/

    ffmpeg version 3.4.1 Copyright (c) 2000-2017 the FFmpeg developers
    
built with gcc 6.2.1 (Alpine 6.2.1) 20160822  

    I’m trying to do dash and hls at the same time.

    In the documentation from here http://ffmpeg.org/ffmpeg-all.html#dash-2

    the key is :

    -hls_playlist hls_playlist
    

    
Generate HLS playlist files as well. The master playlist is generated
    
with the filename master.m3u8. One media playlist file is generated for
    
each stream with filenames media_0.m3u8, media_1.m3u8, etc.

    those. mpd and m3u8 must be created at the same time.

    Running :

    ffmpeg -re \
    
-analyzeduration 20000000 \
    
-i udp: //239.0.0.1: 1234? overrun_nonfatal = 1 \
    
-map 0 \
    
-c copy \
    
-f dash \
    
-min_seg_duration 5000000 \
    
-window_size 10 \
    
-extra_window_size 10 \
    
-remove_at_exit 1 \
    
-hls_playlist 1 \
    
-use_timeline 1 \
    
-use_template 1 \
    
-vtag avc1 \
    
-atag mp4a \
    
cam01.mpd

    and get an error :

    Unrecognized option 'hls_playlist'.  
    
Error splitting the argument list: Option not found`

    without the -hls_playlist
    everything works correctly ...

    What could be the problem ?
