Avisynth opening HEVC?

[Lukas]

Hello,

is there posiibility to open MKV with x265 HEVC video in AviSynth + VirtualDubMod?
I'm trying but I can't find any free x265 DirectShow filter.

[Atak_Snajpera]

use ffms filter

LAV Filters

MPC-BE standalone filters

Not-free:

Cyberlink Video Decoder (PDVD Generic)

Or LSMASHSource ;

Write LWLibavVideoSource or LSMASHVideoSource in your script.

LWLibavVideoSource works for me for pretty much everything; haven't yet seen a reason to use anything else.

I also use this for most everything however when I opened a m2ts hevc file all I got was green and black jumbled lines.

First, remux the video stream to a better container (MKV, MP4) and try again.
If the L-SmashSource keeps failing, then build a .GRF file with GraphStudio (LAV Splitter and LAV Video are mandatory in this case) and apply DirectShowSource() on it.

Or possibly it actually works, but you didn't specify the format parameter, or if higher bit depth whether to output stacked or not

Or the program you're using for preview doesn't display certain bit depths or pixel formats correctly (how are you viewing it)

Use mediainfo for more information on what it's supposed to be

[sneaker_ger]

Very likely it's high bitdepth. L-Smash outputs the hacked format by default, then. You can let it dither to 8 bit:
lwlibavvideosource("source.ts", format="YUV420P8")
Or put into hacked stacked format:
lwlibavvideosource("source.ts", format="YUV420P16", stacked=true)

Into AviSynth+ native format:
lwlibavvideosource("source.ts")
ConvertFromDoubleWidth(bits=10)
See README for more info.

Compatibility of non-8 bit formats can be limited in older software, e.g. VirtualDub.

ffms2 does all this automatically, btw. Easier to use.

Thanks sneaker_ger, I can tell you that

ConvertFromDoubleWidth: top half of the picture showed and bottom half had a green line between the top and bottom and the bottom half looked like analog static. Or perhaps the top half was all of it and bottom half was just static.

stacked=true: This option just showed black and white garbage where you could see bits and pieces of the video.

format="YUV420P8": This worked and was able to open video in vdub.

It is important that you use my examples 1:1 without any changes. (Except file name, of course.)

Though I am sure sneaker_ger's suggestions are good, I have had success with the following:LWLibavVideoSource(<path>, stacked=true, format="YUV420P10")
## 'format' must match source; in this example,
## MediaInfo says "Chroma subsampling" = 4:2:0, and "Bit depth" = 10

ConvertFromStacked(bits=10) ## ('bits' must match format above)
ConvertBits(8, dither=0) ## '0' means on, '-1' means off

[jriker1]

I'm going to have to try a few other suggestions. With format="YUV420P8" it comes up but is really washed out. Almost black and white.

Edit: I am using avisynth+ however it doesn't recognize convertbits

[sneaker_ger]

Is the source HDR? Then things become more complicated.
What is your goal? Smaller file? Convert from HDR to SDR? Both?

Edit: I am using avisynth+ however it doesn't recognize convertbits
Try clean install.

I updated and it loaded however is still washed out. Looks fine in premiere pro when it loaded its own codec but for some reason the video is over a minute short in that tool. Goal is to reduce to 1080p and format to stream well thru my Xbox 360.
