Strange behaviour with FileTexture

vvvv beta question
1

Hi everybody,

after a long time using the VLC-plugin for video-playback - i decided to look back to the build-in features.

with filestream → videotexture the playback is much smoother - but the video has some horizontal stripes always.

i use picvideo 4 64bit and 32bit… the same video pushed through vlc looks perfect

did i missed something???

thanks in advance ;)

the videotextures stripes look like interlacing. you can try VideoTexture (EX9.Texture YUVMixing) to see if it deinterlaces for you (but probably not). else pre-deinterlace your material…

Windows 7 (and therefore filestream) often defaults to its internal decoder for playing back mjpeg the result sometimes looks garbled. Use Graphstudio or have look at Renderer (TTY) to determine which decoder is used. Try Win7DSFilterTweaker to change the decoder if necessary.

thanks for reply

joreg: video file is 100% progressive with square pixels… YUV-Mixing filetexture has the same result…

bjoern:

i´ll check your solution

fu**ing shit… bjoern, you are my hero!!

changing MJPEG to MERIT in Win7DSFilterTweaker solved my problem

1000 thanks!
