[solved] Decoding DNxHD 10bit with MPlayer?

[Selur]

Since I managed to get mencoder&mplayer to playback/decode Apple ProRes I was wondering if someone here knows a way how to playback/decode DNXHD 10bit Material (http://www.limpans.com/DNxHD%20Samples.htm)?
Maybe by using the Quicktime Components coming with the Avid QuickTime Codecs LE 2.1 (http://avid.custkb.com/avid/app/selfservice/search.jsp?DocId=263545)?
(AvidAVdnCodec.qtx should be the one needed,..)

Cu Selur

Ps.: No, I don't want to use Avisynth or any Avisynth plugin to do the job, I'm interested to know if someone know a way do to it with mplayer/mencoder.

Implement 10-bit support in FFmpeg's DNxHD decoder? :)
But in principle yes, using the Quicktime component should be possible, it is basically a matter of adding an entry for it to the codecs.conf file (so should not even need a recompile, though you would probably need a SVN checkout to get an "initial" copy if that file).
There is supposed to be a document describing how to add support for a binary codec somewhere in the documentation but I don't know where exactly.

[Selur]

Looking at the codecs.conf file in the SVN I really need some good documentation to get this working,.. so still hoping someone know a bit more about this,...
(just realized there are two codecs.conf files one in the main folder and one under etc,..)

Okay, I found: http://www.mplayerhq.hu/DOCS/tech/codecs.conf.txt, copied etc/codecs.conf to the folder where my mplayer bianary lies, removed:
videocodec ffdnxhd
info "FFmpeg DNxHD"
status working
fourcc AVdn
driver ffmpeg
dll "dnxhd"
out 422P
and added:
videocodec dnxhd
info "QuickTime Avid DNxHD"
status untested
fourcc AVdn
driver qtvideo
dll "AvidAVdnCodec.qtx"
out YUY2

but judging from the mplayer output: MPlayer Sherpya-SVN-r32492-4.2.5 (C) 2000-2010 MPlayer Team

How fast is decoding?
No gamma, color shifts? It would be better to have YUY2 on the output. Most DNxHD steams will be YUV, only in some cases they will be RGB (DNxHD supports both)

Is decoding multithreaded ?

Andrew

[Selur]

I accidentally deleted my DNxHD test file -> downloading it in the background
No gamma, color shifts?
dont' think so, but definitely nothing major will look at it again once the download is finished,..

How fast is decoding?
Didn't do any benchmarks and I'm not sure how to do one. :) (will try the -benchmark parameter for mplayer)

It woudl be better to have YUY2 on the output.
"out YUY2" gave me a 'VDecoder init failed' and atm. I'm happy to be able to decode the material with mencoder&mplayer at all. :P

YV12 probably would be best if it is supported and the input is 4:2:0.

[Selur]

DNxHD 10bit -> is 4:2:2 ;)

[kolak]

Try simple decode to something easy to encode or uncompressed if you have RAID. This will show possibilities of decoding.

I can get about 1.5x-2x faster than RT decoding to uncompressed (avisynth with QT import plugin).
If it goes through AVID codecs than it will be probably the same. AVID's QT decoder is not multithreaded- this what I have heard.
Would be nice to have faster decoding.

Andrew

[Selur]

it took Mplayer 12.801s to decode a 23 second clip so 2x RT seems to be right,..

[Reimar]

DNxHD 10bit -> is 4:2:2 ;)

Ok, that leaves UYVY and YVYU to try if you want. I think you can also specify multiple formats in order of preference, I just do not know if that will work with the qt binary codecs (the implementation is somewhat... suboptimal).

Thanks, I added that to MPlayer's codecs.conf, so for builds from SVN r32649 or later you won't need to do this change anymore.
It's a good idea to delete your custom codecs.conf version, even though MPlayer should start ignoring it when it notices it is outdated.

Most of these should either already be supported or easy to add support for in FFmpeg. I admit I do not know what OMF is though. Possibly extending DNxHD for 10-bit support wouldn't be that hard either, but the specification (which is SMPTE VC-3) is only for-pay unfortunately (it's not unaffordable but I don't really have time anyway).

Nice! Thanks a lot!
While at it: Could you also change the "printf("-calls in the components.h to "printf(stderr, " calls?
The printf calls break the video output when using stdout-pipes.

Is it this part and then output format?
What do I have to add to save to uncompressed avi?

Did you try with MXF- should be faster.

Thanks,

[Selur]

Can you tell me how to use it please?
I posted the codecs.conf modifications,.. not sure what's unclear. :)

Is it this part and then output format?
Output format is i420 "-vf scale,format=i420" which I from stdout " -o - " to " | x264 ... "

What do I have to add to save to uncompressed avi?
if you change "-o -" to " -o test.yuv" you will end up with a raw i420 file.
If you want another raw format you need to modify the 'format=i420' part,...
If you want the raw video inside an avi you need to change '-of rawvideo' to '-of avi' and "-o -" to " -o test.avi"
(if you remove '-vf scale,format=i420' output should be "UYVY")

Did you try with MXF- should be faster.
No, got no .mxf file here to test.

That's why you should rather use named pipes instead of stdout, but I realize that's a pain in Windows :)
I don't want to change that file since other stuff uses it as well, and if anything it should use mp_msg instead of printf, but I changed it so it will only be printed if you use -v, which for your purpose should have the same effect.

the imx files will probably work with the QuickTime IMX Codec for Windows (http://www.nanocosmos.de/v3/en/quicktimeIMX.html) (400€/ 500$)
the dvpro files should work with the Quicktime DVCPRO HD Decoder (http://www.nanocosmos.de/v3/de/dvcprohd.html) (250,00€/350.00$)
the jpeg2k should work with the Morgan M-JPEG codec V3 (http://www.morgan-multimedia.com/technicalsV3.htm) ($20/20€)
no clue about the wave_hd files

But for the moment, I'm happy with mov(DNxHD) decoding. :P

Yup, downloaded these samples and couldn't playback some them:

op1a-jpeg2k-wave_hd.mxf -> no video - missing 'm3jp2k32.dll', the one in mplayers package was a expired trial so I deleted it some time back
op1a-mpeg2-wave_hd.mxf -> no video - [mxf @ 01d5d5d0] only frame wrapped mappings are correctly supported
op1a-up-wave_hd.mxf -> no video - Cannot find codec matching selected -vo and video format 0x18524742.
op2b-mpeg2-wave_hd.mxf -> broken output - Slices start in the middle!

Wave is audio file- PCM :)
Yes - you need decoders for DVCPROHD etc.

jpeg2k works just fine if you compiled MPlayer with support for libopenjpeg (well, as long as you do not care about speed).
The uncompressed one is probably fixed (well somewhat), but what kind of... well, honestly idiot makes an uncompressed RGB sample that contains only black frames? That's useless for verifying anything.
The others in above list (all are ordinary MPEG-2) play fine for me, I guess you'll have to either remove the -lavdopts threads=... or use -noslices.
The rest is not supported, and honestly this "clip wrapped MXF" is quite nonsense anyway.

MXF is getting bigger and bigger support- it's for broadcast usage, but it would be nice to have one wrapper which works on every platform etc. MXF has a chance.

I'm interested mainly in fast DNxHD decoding. AVID codecs are not the fastest implementation. It's I frame based codec and it should be easy to make it multithreaded, like Canopus HQ or Cineform.
Selur's x264 encode looks fast.

The thing that MPlayer does not support is "clip-wrapped" MXF. Clip-wrapped means you take a random multimedia file and just throw a header in front.
That's not a multimedia format, that is crap, it does not even allow seeking.
However I noticed the clip-wrapped MPEG-2 plays just fine (ignoring the seeking issue).
The clip-wrapped DVCPRO plays only the first frame, since we miss a parser for that format.
However it is possible to play it with -lavfdopts format=dv . Seeking does not work at all, but that is a bug, it should "only" work badly.

How fast is decoding?
No gamma, color shifts? It would be better to have YUY2 on the output. Most DNxHD steams will be YUV, only in some cases they will be RGB (DNxHD supports both)

Is decoding multithreaded ?

Andrew

No gamma, color shifts :)

Is decoding multithreaded ?
don't think so, afaik all the avid codecs are single thread codecs,..

Small update, found two other avid decoders that work CMAvidHDCodec.avx and DNxHDCodec.dll (which come with AVID MediaFuze), here are the codecs.conf entries:

videocodec dnxhd
info "QuickTime Avid DNxHD"
status working
fourcc AVdn
driver qtvideo
dll "CMAvidHDCodec.avx"
out UYVY,YUY2,BGR24

videocodec dnxhd
info "QuickTime Avid DNxHD"
status working
fourcc AVdn
driver qtvideo
dll "DNxHDCodec.dll"
out UYVY,YUY2,BGR24

note, both support YUY2 Output, but the UYVY output is, at least for -benchmark the fastest, but if you need raw YUY2 output one of them are probably the best way to go.
(speed wise all three decoders seem to be equally fast for UYVY output, with my 23 seconds clip; since "AvidAVdnCodec.qtx" is freely available it is probably the one most people will use)

Cu Selur

Ps.: does anyone know if it is possible to add all three codec.conf entries as some sort of alternative for mplayer to choose from?

Nice. Thought it was payware. :)
