The question is to get header size from format context (AVFormatContext) in ffmpeg.

Now i'm using first packet position to get it:

avformat_open_input(&m_formatContext, m_openedFilePath.toStdString().c_str(), NULL, NULL);
//...
AVPacket packet;
if(av_read_frame(m_formatContext, &packet) >= 0)
    printf("Header size: %d", packet.pos); // First readed packet will be with header offset

Any better way to do it without reading frame?
