AvxSynth: a Linux port of AviSynth

[osgZach]

Just wanted to say I hope this project does not die. I would love to see it continue and be successful.
I don't have any meaningful talents to donate to the cause, but I just wanted to show my support for the project.
I completely understand what it is like to have something you believe in, while suffering from a lack of contributors / others who could help.

I would love to fire up a Linux distro one day and use it, when it is in a well-polished "For public consumption" state.

Maybe it would be nice to make AvxSynth "cross platform" instead of just "linux only" so that devs from both sides could help out, etc.

Or at least wish that AviSynth would move to github :P

From what I remember, the DLL loading code in mplayer (see the loader/ directory) looked somewhat reusable. It doesn't have a solution for 32/64bit mismatch though.

We are still working on it. The current focus is a clean build and install, and fixing the worst bugs. Meanwhile, we would like to see more devs join the project.

Hello everybody, my first post in Doom9's Forum.
I began editing video 10 years ago, and learnt a lot about avisynth and video edition at Kvcd.net as member, and in Doom9 as visitor.
And I switched to a linux environment 6 years ago. I just keep visiting Windows to use natively avisynth.
That's the reason I find it so () interesting the avxsynth project.
I don't have programming skills, I cannot help as a dev. But once you find it ready to test, I will be very pleased to help in testing and improving avxsynth.

I wish you success.

Hello everyone...
Awesome job on this project, it was indeed needed.
On my Windows box I ve got Avisynth passing video onto mencoder so I can batch transcode some videos.
My problem when I try the same with Avxsynth on my linux box, is that I only get Video and not Audio.
For some reason, AVXsynthserver only drops video frames on the stdin of mencoder.

Trying to troubleshoot the issue, I realised that axvframeserver , only passes video and not audio on Mplayer also.
My AVS script is a simple

FFVideoSource(pathtomyfile.avi)

If I use FFAudioSource I get only audio and no video.

Any ideas are much apreciated...

A) That's how FFMS2 works, regardless of being used under AviSynth 2.5/2.6 or AvxSynth. The video and audio functions are totally separate. The solution is either to use AudioDub to combine them manually or (if AvxSynth doesn't have issues with .avsi files), to use the FFmpegSource2 wrapping function with the atrack= parameter.

B) There was a point where AvxSynth had issues with using AudioDub. I'm not sure if that's been fixed yet.





How easily could avxFrameServer be modified to also output yuv4mpeg streams? That would allow resolution and framerate (and colorspace?) to be preserved when piping to x264 and co. At least for the time being until AvxSynth-specific import is added and piping is no longer needed.

Currently, the frame server will deliver audio or video, not both. Video gets priority.

I followed the instructions here and everything works fine. However, I skipped the kdev setup steps. Were the kdev setup instructions included for debugging/development purposes?

kdev is necessary if you want to build ant run avxedit, which provides a simple avsedit-like tool to develop and test scripts.

not at all. only need Qt libraries. the master configure/make build avxedit without install kdev

Yes you are right. I was thinking about QT, but the question was about kdev.

[sl1pkn07]

kdev is painfull and rapefathers/killmothers deprecated method XD

edit: only need libqt4-dev. libqt4-designer and libqt4-gui installed by libqt4-dev dependencies

hihihi, an acquaintance ported over (albeit more like "hacked over") fft3dfilter and successfully has it working with AvxSynth. Feel free to try it out and report any bugs.

Please note that this has been relatively untested. So your mileage may very.

Said acquaintance would have posted himself—but he just registered and is waiting for the 5 days to pass in order to post.

I knocked up a quick port to AVXSynth of Donald Graft's Decomb package. Includes 64-bit patches from squid_80. Builds on 64-bit linux with both GCC 4.6 and Clang 3.0, and includes assembler optimisations. It hasn't been made ready for building on 32-bit yet, so expect it to do bad things if you try it.

You need cmake and yasm in order to build it, and cmake must be passed the flag "-DCMAKE_ASM_NASM_COMPILER=yasm" in order for it to use yasm to build the assembler files.

Beyond integrating squid_80's patches, the changes largely revolve around the following (and was otherwise pretty painless to port):

1. Ensuring the correct headers are imported.
2. Ensuring the case in header import statements matches the file name.
3. Differences in what MCSV++ and g++ consider acceptable C++.

I've tested it with a YV12 source, but not with a YUY2 source yet.

Yes, squid_80 has an explanation of what that is about in this post: http://forum.doom9.org/showthread.ph...502#post728502

It doesn't appear to stop anything from working.

[sl1pkn07]

oks. thanks

Distribution packagers and end-users may be interested to know that AvxSynth now has a proper build procedure using GNU autotools. See https://github.com/avxsynth/avxsynth/wiki/System-Setup for instructions.

Additionally, it is excellent to see that plugins for original AviSynth can be ported and remain functional. Those curious may wish to investigate the modified versions of several popular plugins associated with the now-defunct 64-bit port of AviSynth (if JoshyD ever did upload the source -- perhaps he forgot): http://forum.doom9.org/showthread.php?t=152800

[sl1pkn07]

is possible run avxsynth in silent mode? without all error/warnings/info messages (of course. without pipe to /dev/null XD)

greetings
