TIFF/TGA encoder?

Why? It seems too small a task to be done in the course of SoC. --Kostya 09:20, 7 March 2007 (EST)

True, I'll rework it. --Merbanan 11:44, 7 March 2007 (EST)

DPX Encoder/Decoder

From what I understand this is the output of most film scanners. Having not used one I'm not 100% sure of this, and maybe someone could clarify, but my understanding is that film scanners output a collection of these files (I'm unsure if they're put in a container or not). There are already open source implementations in imagemagick and graphics magick.

Should be added to small tasks? Ce 04:41, 8 March 2007 (EST)

No, I'll fix it eventually, it's not that simple.--Merbanan 06:46, 8 March 2007 (EST)

Qualification Tasks

is reviewing and fixing up old unapplied ffmpeg patches not a good small task? Compn 20:25, 8 March 2007 (EST)

I wanted to ask the same question a minute ago;-) The QTRLE patch is not ready yet, and there is no patch for an DNxHD ENcoder in the mailing list. I originally wrote that someone with better knowledge should of course remove those proposals if he thinks they are bad, but I still think they probably tell something about applicants (and that Baptiste possibly didn't read Merbanans "rules"). --Ce 20:31, 8 March 2007 (EST)

Photo Codecs

I see several GSoC project proposals for encoding and decoding a variety of images. Is this truly appropriate for the FFmpeg project, which traditionally focuses on sequences of moving pictures vs. single images? I know that FFmpeg can put a movie together from a sequence of still pictures, or dump a movie into a series of still pictures. Are we hoping to do the same with HDR images? Otherwise, this type of work seems best left to dedicated photo processing projects. --Multimedia Mike 13:36, 9 March 2007 (EST)

And they are designed to operate with colour formats not currently supported by FFmpeg (like 16 bit per component). But JPEG-2000 and HD-Photo are likely to be used in movies so their support is undoubtedly useful. BTW, how do you plan to use qualification projects? --Kostya 14:09, 9 March 2007 (EST)
I'm supportive of something like JPEG-2000 (which uses a colorspace FFmpeg does not presently support, IIRC) since I know that there are plans to include that with certain types of movies. I'm not as enthusiastic about graphic formats that are not known to be encoded as sequences of images in a video file. As for the qualifier projects, we are hoping to weed out unqualified applicants by asking that they perform a task from the list. --Multimedia Mike 16:02, 9 March 2007 (EST)
