Hi Josh, As you know, I'm writing a FLAC ACM codec using libFLAC. The Audio Codec Manager sends messages to the driver with blocks of data to be converted. I think it will be much easier to decode the data if we could use FLAC__stream_decoder_process_whole_stream() to process the first message, not processing any data that don't make a whole frame, and then use

Hi, >That's what I wanted to say a month ago. Mr. Blum, I'm really sorry for misunderstanding you. My mistake. I choose an ACM codec because it's the only option that works on every Windows Platform, and since the DirectShow has a generic wrapper that allows it to use ACM codecs, it appeared a good idea. I didn't note that the file format was going to be a problem. But I think

HI Josh, I'm starting now to compile the ACM codec. I don't know how long it will take, since I do it in my free time, but I guess it will not take to long. About Mark Powell's comment, with an ACM codec there will be a lot of Windows GUIs for FLAC. I'm writing this message to talk about the FLAC format. The GUIs for the Audio Codec Manager, including Winamp and Windows Media

Mr. Blum, I had to make some assumptions writing the driver, because I had no previous experience writing ACM drivers. I did what I could based in Microsoft's documentation but, of course, I made same mistakes. I had no time to test the code I wrote yet and will not in the next 2 weeks. All I can tell you now is about what I did and about my sources. So, considering your enthusiasm, I suggest
