  • Encoding error with Sidekiq

    14 mars 2017, par DavidK

    Im following this tutorial https://www.pubnub.com/blog/2015-12-08-building-video-sharing-app-server-messaging-ruby/ on Building a Video Sharing App. Its a bit outdated and Ive already had to fix a view issues to get this far but Im pretty lost now with this latest issue. I believe its something to do with sidekiq. When I try uploading a video it seems to work and shows up on the database, but I get a "Video is still being encoded." message.

    This is the log :

  • Why does av_write_trailer fails ?

    31 mai 2013, par user1914692

    I am processing a video file.
    I use ffmpeg to read each packet.

    If it is an audio packet, I write the packet into the output video file using av_interleaved_write_frame.

    If it is a video packet, I decode the packet, get the data of the video frame, process the image, and compress back to a packet. Then I write the processed video frame packet into the output video file using av_interleaved_write_frame.

    Through debugging, it read audio packets and video packets correctly.
    However, when it goes to "av_write_trailer", it exits. But the output video file exists.

    The error information is :

    *** glibc detected *** /OpenCV_videoFlatten_20130507/Debug/OpenCV_videoFlatten_20130507: corrupted double-linked list: 0x000000000348dfa0 ***

    Using Movie Player (in Ubuntu), the output video file can plays the audio correctly, but without video signals.
    Using VLC player, it can show the first video frame (keep the same video picture), and play the audio correctly.

    I tried to debug into "av_write_trailer", but since it is in the ffmpeg library, I could not get a detailed information what is wrong.

    Another piece of information : the previous version of the project is only to process the video frame, without adding audio stream ; and it works well.

    Any hint or clue ?

  • Bad audio output in stereo mode - FFMPEG PortAudio C++

    26 août 2014, par Spamdark

    I’m here again. This time I am working with the audio, I had before some memory leaks issues but now they are solved, this time I am here with a new problem, when I configure portaudio to sound in stereo (channels = 2), the audio outputs in a bad quality.

    It only outputs good in mono, there is almost no solution in google (Or I am a bad ’googler’), here is the code :

    Thread that plays audio :

    int16_t* audioBuffer=(int16_t*)av_malloc(FRAME_SZ_AV);
    

    

    
int sz = MEDIA->DecodeAudioFrame(audioBuffer,0);
    

    
if(sz==1)
    
    Pa_WriteStream(MEDIA->output_stream,audioBuffer,MEDIA->_audio_ccontext->frame_size);
    

    
if(sz!=1)
    
    MessageBox(0,"error","error",MB_OK);
    

    
ZeroMemory(audioBuffer,FRAME_SZ_AV);
    
av_freep(&audioBuffer);

    DecodeAudioFrame function

    int WbMedia::DecodeAudioFrame(int16_t *audio_buf, int buf_size){
    
int return_status=0;
    
AVPacket t_pack;
    

    
while(!audio_packets.empty()){
    
    // Get new packet
    
    WaitForSingleObject(Queue_Audio_Mutex,INFINITE);
    
    t_pack = audio_packets.front();
    
    audio_packets.pop();
    
    ReleaseMutex(Queue_Audio_Mutex);
    

    
    int obt_size = AVCODEC_MAX_AUDIO_FRAME_SIZE;
    
    int consm = avcodec_decode_audio3(_audio_ccontext,audio_buf,&obt_size,&t_pack);
    
    if(consm > 0 && obt_size > 0){
    
        return_status=1;
    
        break;
    
    }
    
    return_status=-1;
    
    break;
    
}
    

    
av_free_packet(&t_pack);
    

    
return return_status;
    
}

    PortAudio Settings

    output_params.device = Pa_GetDefaultOutputDevice(); //choosen_device.dev_index;
    
output_params.sampleFormat=paInt16;
    
output_params.channelCount=channel_count;
    
output_params.suggestedLatency=choosen_device.dev_inf->defaultLowOutputLatency;
    
output_params.hostApiSpecificStreamInfo=NULL;
    

    
// Start with PA opening
    
PaError pa_opening_err = Pa_OpenStream(&output_stream,
    
    NULL,
    
    &output_params,
    
    sample_fr,
    
    _audio_ccontext->frame_size,
    
    paNoFlag,
    
    NULL,
    
    NULL
    
);

    Why is the audio outputting in bad quality in stereo and not in mono ? How can I fix it ?
