    26 février 2017, par asad

    Hi iam using following c++ code to create ffmpeg command. When i run this command in bash using linux popen, following error occurs. If i put the command directly in bash, it works fine and doesn’t give any other. Please help me figure out the cause of it.

    C++ code to generate command :

     const string VideoCreator::GetFFMPEG_Silent_Audio_Merge_command()
    
{ 
    
    stringstream command;
    
    command << FFMPEG_BINARY  << " -nostdin -loglevel error -y -threads 0 -f concat -safe 0 -i <(echo file /home/ec2-user/videoData/DnXptC4ld8/FADING_OUT_VOLUP_Blrt_Decrypt_1ed5c4d569d8a1f23428b65217f65eaf_audio.m4a; echo file /home/ec2-user/videocreation/temp/silence.m4a) -c copy " << _outputAudioWithSilence;// << " 2> " << _ffmpeg_log_file;
    
    std::cout << "\n Command = " << command.str() << "\n";
    
    return command.str();
    
}

    Bash error :
