Mark FD -

I am definitely interested in seeing the code. Did you write it in a programming language other that C++? I finally figured out how to write a YUV version of colorbars(). Dividee told me how to handle the audio, so now it works. I am using the invert filter as a pattern. I need to compare that with simple filters that work entirely differently.

No, no, sbasic is really a neat new programming language!

If you can really write a filter in basic instead of cpp I'd like to see how that is done.

quoting myself :
>i wrote first : "simple"

i didn't mean basic as a langage. "basic instinct" is not a film about computers

Hello MarcFD,

the new 2.5 beta is out and your fantastic filter is not running anymore :

"Plugin raw422.dll is not an AviSynth 2.5 plugin"

would be cool, if you had time to fix it.

Thanks again,
hanfrunz

MarcFD has abandoned development and this filter has no source code.
Stick to 2.0 for this application (you can safely use two versions)

I made a new version for importing YUV-files (WITH source code):

http://www.avisynth.org/warpenterprises/

RawSource(filename, width, height, pixeltype)

e.g.

RawSource("d:\src6_ref__625.yuv",720,576,"UYVY")

Change the framerate with AssumeFPS(30) if it is not 25fps.

"pixeltype" isn't the internal AviSynth-format, but the format in the YUV-file. This will be mapped correctly, without any resampling.
Supported types:
RGB, RGBA, BGR, BGRA, YUYV, UYVY, YVYU, VYUY

Remember, this plugin reads video files which contain many frames.
It works for reading ONE frame, but not for file sequences (they must be loaded separately).

Actually I think Richards ImageReader/ImageWriter supports YUV images by now (in ebmp mode).

@WarpEnterprises,

1) what do you use to make such a yuv clip?

2) No NTSC support?

Sorry, I misread the docs. There is NTSC support.

I have one small request thought Could you add I420 and YV12 support?

The only free avi2yuv tool I could find:

http://www.ee.surrey.ac.uk/Personal/S.Worrall/dloads/

converts uncompressed RGB stuff (= tried XviD encoding, didn't work) to I420.

I hate YV12 :-)

ac-chan123, your problems with the xiph videos come from that format.

It is a little more typing to add this and I have to download some frames first, but I will give it a try (which gives the answer to Wilbert, too).

OK, get the new version with YV12 and I420 support.

@ac-chan: try

RawSource("d:\blue_sky.yuv",1920,1080,"YV12")

This is true. Right now it uses a small custom RIFF header to set the image parameters, but these could be specified as filter arguments (to the Reader) if there was demand.

@Richard:

- Is that ebmp == the custom RIFFed filed?
- ImageWriter: would it be possible to APPEND all written images to ONE file (without header), with this it would be possible to generate those YUV files, maybe useful for testing purposes.

It is clear that we (ImageReader/RawSource) have some overlapping functionality but I don't see how to combine it nicely.

I added YV12 support for you! Not bad for someone who can't program

I failed to add I420 (which is what I really want). I tried to add the code of SwapUV, but I couldn't get that to work. But there might be a simplier way.

Could you have a look at I420 support?

I420 clip (640x480, 25 fps):

http://www.geocities.com/wilbertdijkhof/raw.yuv

source+dll:

http://www.geocities.com/wilbertdijkhof/RawSource.zip

Note that if you open the clip as YV12, you will see that the output is correct except that the U and V channels are swapped. Thus YV12 input is correct since YV12 = I420 with swapped U and V.
