I have a existing mp4 file to which I wish to append a few more frames. What is the file writer parameters method to create a file writer to append data. For instance, if I create file writer like this:
m_fileWriterParams.m_portion_size = 0; vm_string_strcpy(m_fileWriterParams.m_file_name, (wchar_t *)m_inFileName.c_str()); status = m_fileWriter.Init(&m_fileWriterParams);
It erases all the data in the current mp4 file. How do I initialize it in "Append" mode?
