Description

Summary of the bug:
I have tested it with more files from different sources, on fresh compiled git version of ffmpeg, on ffmpeg compiled without "libopenjpeg", but it doesn't work - R3d files from RED Cinema cannot be decoded.

Sorry, is there a timetable for red support? R3d is listed as supported decoder - so for me it's look more like bug as enhancement or wish. Can i help in any way?

http://thread.gmane.org/gmane.comp.video.ffmpeg.devel/78938
http://thread.gmane.org/gmane.comp.video.ffmpeg.devel/80922
Old version ("3") r3d files are "supported" insofar as the can be demuxed but since FFmpeg currently does not (yet) support Bayer colourspaces, the files cannot be decoded.
The file you uploaded is version "4", either this version needs a patch to the demuxer or to the decoder, in any case, that wouldn't fix the missing Bayer support.

comment:10 by Elliott, 11 years ago

Would it be possible to utilize the official RED SDK to decode these files in ffmpeg? It's free, but not open source. You can read their license agreement at http://www.red.com/docs/RED_R3D_SDK_Agreement.pdf
I think this would be preferable to rewriting it from scratch, because the R3D format is under such heavy development by RED, and it would be too hard to keep up with the frequent updates to their color science, etc.

Is it compatible with the GPL or the LGPL in your opinion?

comment:12 by Elliott, 11 years ago

I think it would be compatible with LGPL, so you can avoid distributing their source code. But this legal stuff is way over my head, so I'm not sure.

comment:13 by Elliott, 11 years ago

This is the response I got from RED's legal team:

You are not allowed to distribute any of the R3D SDK documentation, header files, sample code or library files directly. This means you would have to create either a custom ffmpeg binary people can download, or provide some sort of binary plugin if ffmpeg has such a system.

Is this doable?

in reply to:  13 comment:14 by Carl Eugen Hoyos, 11 years ago

Replying to spookybathtub:

Don't you agree that it would be much simpler to get the (existing) Bayer patch(es) into FFmpeg and update the demuxer?

Note that if it would be legal to distribute such a binary of FFmpeg (I think this is unlikely but ianal) it would not be legal to have x264 support (which is what most people want).

comment:15 by Elliott, 11 years ago

Cc: elliottbalsley@gmail.com added

I'm not sure which would be simpler. I don't know how to code any of this myself, but I am very grateful for all the work done by the ffmpeg developers so far.
I do know that the SDK provides a huge amount of options for how to process R3D raw files, and many of these options are essential when dealing with RAW — for example you have to set the ISO, white balance, etc. before converting to a linear color space. It seems like it would be rather difficult to recreate all these settings.
I've read that about 3 years ago, RED started using some kind of encryption in the files. See http://ffmpeg.org/pipermail/ffmpeg-user/2011-September/002444.html

As an alternative, RED provides a free command line conversion tool called REDline, but I can't figure out any way to pipe its output to ffmpeg. If anyone else wants to try, you can get it here: https://drive.google.com/file/d/0B52QuT8oHvtZZE5TMmdfSVZybFU/edit?usp=sharing. If that can be made to work, then there is hardly any reason to develop native R3D support in ffmpeg.

I agree it would not be practical to distribute crippled ffmpeg binaries, but is it possible to make some kind of "binary plugin" that doesn't reveal the source code, but can be used when compiling ffmpeg?

Why?
Consider discussing this on ffmpeg-user.

Why??

comment:17 by Elliott, 11 years ago

R3D is an extremely complex codec, with dozens of raw processing parameters that need to be specified, and color science that is under heavy development by RED. Also, REDline takes advantage of the Red Rocket hardware accelerator card for a huge speed benefit over CPU.

The R3D SDK is kept up to date, and supports Red Rocket. But if licensing prohibits that, then I suppose the alternative would be to write a decoder from scratch. In that case, it seems unlikely that ffmpeg developers could keep up to date with the color science and perform the debayer and raw conversions accurately. But maybe I'm wrong.

codec? Isn't it just a relatively simple format with jpeg2000 in it?

with dozens of raw processing parameters that need to be specified, and color science that is under heavy development by RED.

Check out all the color filters in libavfilter, including lut3d.

Also, REDline takes advantage of the Red Rocket hardware accelerator card for a huge speed benefit over CPU.

I wonder what this has to do with the software implementation.

Isn't the issue just about supporting some random pixel format, just like with XYZ with D-Cinema? (recently added)

lol

Yes.

The pixel format is Bayer, a patch was sent but is unfinished.

comment:20 by Elliott, 11 years ago

Yes, it's a bayer pattern, and it does use a modified JPEG2000 wavelet compression. But the debayered image is raw data with no specific color space until it is converted with RedColor3 or some other algorithm.

comment:21 by compn, 10 years ago

bayer colorspace support was added a few months ago.

whats next to support .r3d ?

in reply to:  21 comment:22 by Carl Eugen Hoyos, 9 years ago

Replying to compn:

bayer colorspace support was added a few months ago.

FFmpeg supports bayer formats with 8 bit per pixel and 16 bit per pixel, the r3d formats have 12 bit per component (48 bit per pixel).

comment:23 by Elliott, 9 years ago

That used to be true, but the current cameras are 16 bit.

comment:24 by compn, 9 years ago

do these 16bit bayer colorspaces have to be reverse engineered ?

can someone upload a 16bit r3d file for testing with? possibly with the original input so we can make sure its identical decoding.

comment:25 by Elliott, 9 years ago

I can upload a sample. What do you mean by "original input"?

comment:26 by compn, 9 years ago

something so we know what the input looks like. correct colors and stuff. screenshot etc

comment:27 by Carl Eugen Hoyos, 9 years ago

Please find the requested samples in http://samples.ffmpeg.org/r3d/

comment:28 by Elliott, 9 years ago

Those samples are ancient, and not 16 bit. I don't know the best way to upload samples here, but here is a recent sample from RED Dragon, along with two JPEG references — one debayered as REDlogFilm, and the other as REDgamma4. Both use DRAGONcolor2. Note: The JPEG preview on Google Drive does not look right at all, probably because it can't handle this high resolution (6144x3160).

Hi Peter,

Your PoC sounds promising!

I have a few queries:

  • Would it be feasible to concatenate spanned R3D clips and incorporate an audio track from a WAV file?
  • Is there a possibility of integrating your code directly into FFmpeg?

We are in the midst of developing a server encoding application tailored for raw camera files, including XDCAM and R3D. However, the absence of comprehensive R3D support in FFmpeg poses certain limitations. Given the importance of this feature for our project, we're considering sponsoring its development.

One of my primary concerns revolves around potential copyright challenges, especially when implementing the RED SDK in an open-source framework.

I'd appreciate your insights on these matters.

Only just realized that Red footage wasn't compatible with ffmpeg today, but sounds like it's been an ongoing issue for some time.

Any updates on this one?
