  • Compiling FFmpeg on OSX - "speex not found using pkg-config"

    19 septembre 2016, par n4zArh

    I recently had few problems with FFmpeg and compiling it to get library. I managed to get through all of them, however recently I found out I need to add Speex decoder (and possibly encoder) to my project. I got Speex by sources, ./configure and make;make install (later - as I had problems - I also used Brew to download Speex). I added --enable-libspeex to my configure script and every time I try to use it I get "Speex not found using pkg-config" error.

    I am sure that there’s Speex files at /usr/local/include and lib directories, I also added those two as CFLAGS and LDFLAGS, I tried building Speex with or without using --prefix (both pointing to /usr/ and /usr/local/), I tried modifying FFmpeg’s configure file (require_pkg_config with Speex call), but no matter what I try to do I fail to build it - every time with same error.

    Long story short - how to build FFmpeg with Speex decoder on OSX ? I read somewhere that libspeex-dev might be needed, but it’s available through apt-get and not Brew (unless I screwed something up).

    My build script :

    #!/bin/bash
    

    
if [ "$NDK" = "" ]; then
    
    echo NDK variable not set, assuming ${HOME}/android-ndk

  • mediastreamvalidator "Error injecting segment data" and Can't deal with multiple sample timings per sample buffer

    14 juin 2018, par Dathan Vance Pattishall

    So using ffmpeg

    /usr/local/bin/ffmpeg -i track.m4a -vn -c:a aac -b:a 192k  -f segment -segment_list 93_jrf2niqb7n2s8pzjopkqvbbw1wmzz3foqrsa93bm.m3u8 -segment_time 120 -segment_format_options movflags=faststart  93_jrf2niqb7n2s8pzjopkqvbbw1wmzz3foqrsa93bm.%03d.m4a

    a playlist file is created where

    #EXTM3U
    
#EXT-X-VERSION:3
    
#EXT-X-MEDIA-SEQUENCE:0
    
#EXT-X-ALLOW-CACHE:YES
    
#EXT-X-TARGETDURATION:121
    
#EXTINF:120.000726,
    
93_jrf2niqb7n2s8pzjopkqvbbw1wmzz3foqrsa93bm.000.m4a
    
#EXTINF:119.883175,
    
93_jrf2niqb7n2s8pzjopkqvbbw1wmzz3foqrsa93bm.001.m4a
    
#EXT-X-ENDLIST

    Then using mediastreamvalidator I get the following output which leads me to believe there are errors which I have no idea how to fix. I am assuming that ffmpeg is jacking up the segmenting.

    I wish to remove the "original display aspect ratio" entry from the video section.

    I tried the following commands,

    



    ffmpeg -i input.mp4 -map_metadata -1 -c copy output.mp4

    



    ffmpeg -i input.mp4 -metadata original_display_aspect_ratio=0 -c copy output.mp4

    



    but none of them worked.

    



    If I want to remove the "original display aspect ratio" entry completely, what ffmpeg command can I use to achieve that ?

    



    Thank you.
