Q: Will this APIi also convert popular audio formats only like MP3, WMA etc.? I have audio files without any video that I would like to convert to flv.
If so, what's the complete list of formats that it'll support?
A: Flash Video MX SDK V2 can convert any audio files into flv files as long as your audio file can be played on your computer. If it can not be played, please install the corresponding encoder. There is a Codec List in the installation folder, which introduces the needed encoder and download link when you can not play one kind of file form.
In the Flash Video MX SDK V2 Command Line interface, you can use -sa audio file to add audio to convert flv. When you are using -s source_file, it will add the audio and video in the source_file. You can also use option -l, -t to add image, text watermark. In this way, the generated flv files will contain the audio you wanted and image, text watermark which you like.
In the Flash Video MX SDK V2 COM interface, it provides AddAudioSource, AddImageWaterMark, AddTextWaterMark to complete the corresponding functions.
