  • FFMPEG audio conversion is taking too much time

    26 octobre 2018, par Sachin Varma

    How to make the audio conversion ultrafast ?

    It is now taking more than 2 minutes for converting an audio around 2mb in size.

    The command i’m using for execution of conversion is

    String[] cmd = {"-y", "-i", audioPath, outputPath};

    How to preset the ultrafast mode ?

    While i’m trying it like

    String[] cmd = {"-y", "-i", audioPath,"-preset", "ultrafast" ,outputPath};

    It is taking same time itself.

  • FFMPEG HLS Multiple audio languages with var_stream_map - EXT-X-MEDIA:TYPE doesn't contain LANGUAGE

    30 janvier 2020, par Moonsurfer_1

    I have a question involving multiple audio languages on HLS with FFMPEG.

    I’m currently using the following command to mux a transport stream with multiple audio languages into an HLS stream with a master playlist :

    ffmpeg -re -i $INPUT_URL -map 0:v -c:v copy -map 0:a -c:a copy -f hls -hls_time 6 -hls_list_size 10 -hls_flags delete_segments+program_date_time -hls_segment_filename "$FULL_OUTPUT_FOLDER/stream_%v_%d.ts" -var_stream_map "v:0,agroup:groupname a:0,agroup:groupname a:1,agroup:groupname a:2,agroup:groupname a:3,agroup:groupname" -master_pl_name master.m3u8 $FULL_OUTPUT_FOLDER/stream-%v.m3u8

    The output of this command looks like this :

    The master playlist that’s being output by this command looks like this :

#EXT-X-STREAM-INF:BANDWIDTH=174900,CODECS="mp4a.40.2",AUDIO="group_groupname"

#EXT-X-STREAM-INF:BANDWIDTH=174900,CODECS="mp4a.40.2",AUDIO="group_groupname"
    
stream-4.m3u8

    While this does seem to work with VLC, I need the EXT-X-MEDIA:TYPE tag to contain the LANGUAGE property. (the player I’m working with uses it to parse the audio tracks’ language) I can’t figure out how to do that based on the documentation I’ve found.

    Could anyone help me with this ?

    Thanks !

  • Integrating FFMPEG using cmake : undefined reference when linking libraries

    21 novembre 2018, par Hamed Momeni

    I’ve been trying to cross-compile ffmpeg for different Android cpu archs for couple of days now and I have finally succeeded in the task. But now that I need to integrate these pre-built .so files in my project I’m facing errors which have me baffled.

    This is the CMakeLists.txt which I’m using :

    cmake_minimum_required(VERSION 3.4.1)
    

    
# convert SDK path to forward slashes on Windows
    
file(TO_CMAKE_PATH ${PATH_TO_SUPERPOWERED} PATH_TO_SUPERPOWERED)
    

    
set(CMAKE_VERBOSE_MAKEFILE on)
    

    
include_directories(src/main/cpp)
    
include_directories(${PATH_TO_SUPERPOWERED})
    
include_directories(${PATH_TO_FFMPEG}/${ANDROID_ABI}/include)
    

    
add_library(
    
        avutil
    
        SHARED
    
        ${PATH_TO_FFMPEG}/${ANDROID_ABI}/lib/libavutil.so
    
)
    
set_target_properties(avutil PROPERTIES LINKER_LANGUAGE CXX)
    

    
add_library(
    
        avformat
    
        SHARED
    
        ${PATH_TO_FFMPEG}/${ANDROID_ABI}/lib/libavformat.so
    
)
    
set_target_properties(avformat PROPERTIES LINKER_LANGUAGE CXX)
    

    
add_library(
    
        avcodec
    
        SHARED
    
        ${PATH_TO_FFMPEG}/${ANDROID_ABI}/lib/libavcodec.so
    
)
    
set_target_properties(avcodec PROPERTIES LINKER_LANGUAGE CXX)
    

    

    

    
add_library(
    
        Canto
    
        SHARED
    
        src/main/cpp/Dubsmash.cpp
    
        src/main/cpp/Karaoke.cpp
    
        src/main/cpp/Singing.cpp
    
        src/main/cpp/EditDubsmash.cpp
    
        ${PATH_TO_SUPERPOWERED}/AndroidIO/SuperpoweredAndroidAudioIO.cpp
    
)
    

    
# link the native library against the following libraries
    
target_link_libraries(
    
        Canto
    
        avutil
    
        avformat
    
        avcodec
    
        ${PATH_TO_SUPERPOWERED}/libSuperpoweredAndroid${ANDROID_ABI}.a
    
        OpenSLES
    
        log
    
        android
    
)

    And this is the source of the file I’m getting errors on :

    #include 
    
#include <android></android>log.h>
    
#include <string>
    
// unrelated includes
    
#include <libavformat></libavformat>avformat.h>
    
#include <libavutil></libavutil>dict.h>
    

    
#define log_write __android_log_write
    
#define log_print __android_log_print
    

    
// unrelated code parts
    

    
int print_file_data(const char *filePath) {
    
    AVFormatContext *fmt_ctx = NULL;
    
    AVDictionaryEntry *tag = NULL;
    
    int ret;
    

    
    if ((ret = avformat_open_input(&amp;fmt_ctx, filePath, NULL, NULL)))
    
        return ret;
    

    
    while ((tag = av_dict_get(fmt_ctx->metadata, "", tag, AV_DICT_IGNORE_SUFFIX)))
    
        log_print(ANDROID_LOG_DEBUG, "%s=%s\n", tag->key, tag->value);
    

    
    avformat_close_input(&amp;fmt_ctx);
    
    return 0;
    
}
    
</string>

    And finally the errors themselves :

    Obviously the linker can not find the needed libraries, but why ?!

    UPDATE 2
    I applied @szatmary suggestion and finally managed to to build the apk file but upon reaching the System.loadLibrary call an exception occurs indicating that the linker can not find libavutil.so.56. I tried changing the address of the library in the cmake file to actually contain the version numbered lib file to no avail :
