QuickTime IMA ADPCM Encoder
Is this related to http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2008-February/042475.html ?
- I assume so. I am watching that patch too. --Multimedia Mike 14:32, 25 February 2008 (EST)
And this to This patch?
Realistic time frame
A problem that has come up in past years is the number of projects that go uncompleted. I think the Matroska muxer was the only project that was actually completed by the end of the summer. If the student is willing to continue working on a project past the end of summer then that's great, but we should try to estimate a realistic time frame. In looking over the current project list, I think the following could reasonably be completed in three months time:
- ALAC encoder
- Speex decoder
- MXF muxer
These are all very clearly defined tasks, as opposed to some things involving psychoacoustics and perceptual coding, which can be very open-ended. -Mkhodor 06:00, 26 February 2008 (EST)
- I'm not sure about the ALAC task. Do we have enough complete information documented for a student to reasonably complete the task? --Multimedia Mike 11:59, 26 February 2008 (EST)
- We have a working, not too obfuscated decoder. Also, I think it is similar enough to FLAC to put the student in the right track. Also, the original author of the alac decoder says :
Although an encoder is not provided, by using the decoder as a sort of specification it should be fairly trivial to write an encoder. By exploiting other lossless audio encoders, such as FLAC, the task will be much easier. Although one wouldn't be able to copy the compression algorithms verbatim, as adaptive compression is used in ALAC and not in FLAC. There are, however, a bunch of academic papers on the issue.

It could be done based on the G.722.1 specification as banan suggested once somewhere.
(I know, I haven't submitted the G.722.1 decoder yet, but it's almost cook with different huffman tables and a 320-point iMDCT) (posted by User:Angustia)
- I want to see some more solid documentation before I will consider it for a project. I also need a mentor for such a project. --Multimedia Mike 13:03, 27 February 2008 (EST)
I'm a bit sad because the completion of snow and it's specification doesn't appear as a potential SoC project. Is there a reason for this?
No - I'm not one that could do this. (posted by User:Elte)
