I'm completely unfamiliar with ffms2 internals and never tried to build it myself (I am building ffmpeg for other projects though, such as mpv, cross compiling in MXE, FWIW), but these 2 options could be useful and AFAIK they work rather well in ffmpeg.

hwaccel (i'm guessing that's dxva2?) actually reduces cpu load and power usage when used, and network _should_ work (can it actually be used to play network clips via avisynth?).

If that matters, I'm using ffms2 as a source plugin together with SVP.

[qyot27]

I'm not sure if FFMS2 allows using the dxva/vdpau/vda/etc. decoders, especially since there is also currently no way (in FFMS2) to select one decoder out of many for the same format that might exist in libavcodec. And I have no idea if the network support would work correctly. AviSynth did/does have the TCPSource/Deliver plugin (not that I've ever used it), but I don't know if it would have an effect in FFMS2.

The reality is that those four options (disable-network, disable-hwaccels, disable-indevs, and disable-outdevs) have been in the build options I've used for a long time. They were suggested quite a number of years ago in the API docs (https://github.com/FFMS/ffms2/blob/master/doc/ffms2-api.md#compilation) and in this thread (http://forum.doom9.org/showthread.php?p=1367924#post1367924), so part of it is just not running any tests on either one to see how necessary it actually is nowadays - unlike the encoders and muxers, which are completely useless for FFMS2 and reduce the size of the .dll by a good amount.

[avih]

Well, mpv (http://mpv.io/) uses ffmpeg's hwaccel (vpdau, dxva2, etc) and it's quite effective on windows and AFAIK on other platforms as well. As for usage for network sources via ffmpeg, imagine youtube clip url into ffms2 into svp into mpv ;) I got this exact chain working well for local files now with a system which generates an avs file on the fly, but doing the same for a network clip could be cool...

Maybe I'll try to build ffms2 myself with different ffmpeg options..

[LigH]

Not for every GPU, using the decoder chip will be a speedup compared to CPU decoding.

And if I have to be afraid that the GPU decoding applies an undesired IVTC or deinterlacing without control, I would not use FFMS2.

The YouTube example won't work, unless you do it the hard way and go through RTMP. Just giving FFmpeg the https:// url won't do anything, and thus FFMS2 won't either.

mpv supports playing streaming media through a youtube-dl bridge, only falling back on FFmpeg's network stuff if the ytdl loader fails. FFmpeg's tenuous support of it was provided through libquvi (which mpv also used to use, before dropping it in favor of ytdl), which is mostly completely broken/outdated now and should be removed from libavformat.

Hello, I'm having a bit of a problem and can't figure out why:

Win7x64

Someone please explain what I'm doing wrong? It simply won't open it. Nothing being returned besides usual "can't open file" error by MPC/Vdub.

Before I download this file, could you post a MediaInfo report about it? Maybe it contains a video or audio stream format not supported by FFMS2?

I know it is xtor, I recorded it. The thing is - I can't open it through ffms2 via avs script. It boggles my mind.

[qyot27]

From the MediaInfo output in the issue on Github (https://github.com/FFMS/ffms2/issues/194):
Writing application : DxtoryCore ver2.0.0.127

2.20 is from June 20th, 2014.

The FFmpeg git log, with a search for 'dxtory'. (http://git.videolan.org/?p=ffmpeg.git&a=search&h=HEAD&st=commit&s=dxtory):
2014-09-25 Michael Niedermayer avcodec/dxtory: Support dxtory-2.0.127.avi

The problem is that the official build of FFMS2 2.20 is not using a build of FFmpeg new enough to decode the file, because the build is from three months prior to that being committed to FFmpeg.

It's also why it's fixed in the C plugin builds, because those use reasonably updated versions of FFmpeg.

[Kein]

I just recorded another clip from this and another game with the same codec and same options and then opened it just fine (with your version of the plugin, ffms2_r940c64-avs_vsp). But that particular clip I cannot.

It works just fine elsewhere. It is not damaged. There is nothing special about it. You can open. Why I can't?

[kolak]

Can we have ffmpegsource based on "current" (2.6) ffmpeg, please?

Did you load ffms2.dll with "LoadCPlugin" or just copy it to your auto-load directory? Your file also works for me with r940c64.

[stax76]

Possibly ffms2 misses to release a file handle, I use the avifile API, after releasing and cleaning everything the process still locks the source, I tried other source filters and it happens only with ffms2.

[stax76]

With latest C plugin build when I open 2-3 movies seeking around in StaxRip's preview memory grow up quickly causing a out of memory exception at 1,5 GB.

With the 2.20 release memory stays always below 850 MB.

Specs of test file: http://pastebin.com/MxqcTkRh

[qyot27]

This has been a mysterious leak for a while. It came up regarding MeGUI a year ago, and I could reproduce it in VirtualDub:
http://forum.doom9.org/showthread.php?p=1674911#post1674911

But I wasn't able to find where it was doing it in the C interface part of FFMS2.

[stax76]

Any ideas on the file lock?

edit: happens also with c plugin only

Another issue with Dxtory and FFmpeg.

For some reason ffms detects source as 1920x1080@44FPS while it was recorded in 60. What gives?

Thanks !
Finally a decent replace for the rather poor ffdca !!
Note : currently no support for 192 kHz sample rates , just up to 92 kHz !

I have a question about the license:

The source is MIT licensed and can be obtained from https://github.com/FFMS/ffms2/. The precompiled binary is GPL3 licensed. (...)
I don't understand this construction. As I understand it you can only license the software (being the binary here). The binary can be released under different licenses, and you (if one wouldn't be the sole copyright-holder) can release it under a compatible license. It doesn't make any sense to me to say that the sourcecode is licensed under a particular license. Perhaps i'm missing something ...

Well, to my understanding, the copyright-holder can put his/her own code under whatever license he/she wants. The code can even be released under multiple different licenses at the same time - as many projects do.

Now, if you combine your own code with someone else's code, then the combined work needs to be distributed under a compatible license, of course. So, if the authors of FFMS2 decide to release their own code under the MIT license, they are of course free to do so! But as soon as a binary is created, which unavoidably contains some FFmpeg code too, then the whole thing must be distributed under the LGPL or GPL - depending on what FFmpeg feature are enabled. That's because FFmpeg is released under the LGPL - and partly under the GPL. And the GPL/LGPL is more restrictive than the MIT license. You can combine MIT'ed code with GPL'ed or LGPL'ed code, but the combined work has to be distributed under GPL/LGPL then.

Unless I'm missing anything here, this should be fine :confused:

What exactly is the confusion? Certain source files in ffms2 are licensed under something like the MIT license, but the project also contains GPLed code. So as a whole the combined work, the binary, is licensed under the GPL per the way the GPL works. It's no different than how countless other projects such as the Linux kernel work. The Linux kernel is overarching GPLv2, but it contains MIT/BSD/etc. more permissive licensed code in it as well. There is nothing exotic or out-of-the-ordinary here.

[Wilbert]

Guess i should think a little bit before asking. I forgot that you are combining GPL en MIT code. How stupid.

Greetings qyot27. Appreciate your continuing effort to update ffms2.

Is this to be used with Avisynth 2.58?

Many thanks and best regards.

[qyot27]

2.5 is still supported, at the moment. But the C plugin's purpose had shifted to giving 2.6 precedence years ago.

[mariner]

Thanks for the kind reply, qyot27.
I take it yours is the preferred version to the official 2.2 built?
Many thanks and best regards.

My builds of the C plugin are simply updated more often. 'Preferred' is purely subjective.

Thanks qyot27. Two questions:

1. Can this deal with interlaced content?
2. And what about interlaced content that's been encoded as progressive (as reported by mediainfo) in a ts container? Or is there a way to flag these as interlaced without re-encoding?

Many thanks and best regards.

[qyot27]

I don't know, as I've never had to handle interlaced H.264 with FFMS2. Since the latest builds have the Haali splitters removed, its performance should map fairly equally to how it's handled in FFmpeg itself.

[Selur]

Or is there a way to flag these as interlaced without re-encoding?
iirc there's a modified ffmpeg version floating around which can remux and change the interlaced flag,..

[StainlessS]

iirc there's a modified ffmpeg version floating around which can remux and change the interlaced flag,..

Dont know about that, but there is one to hack Aspect Ratio:-

http://forum.doom9.org/showthread.php?t=152419

[Selur]

damn, thought that one could also change the interlaced flags,...

[LigH]

There is quite a difference between PAFF and MBAFF interlacing. It's more than a matter of setting flags. You would confuse a decoder substantially if you patched them wrong.

MultiAVCHD was not able to display the menu and video when the r944 files was placed in the Avisynth plugin folder. No issue with the official 2.2 build. What may have caused this?

Did you also put the file FFMS2.avsi in the plugin directory ?
You need to do so, because this is a C-plugin and it will not autoload without the FFMS2.avsi file being present in the same directory.

[LigH]

AviSynth+ (note the plus) is able to autoload AviSynth C plugins; the original AviSynth 2.x is not, therefore the import script (with additional declared convenience functions).

[mariner]

Thanks for the reply, Pat.

All the three files are placed in the plugin directory.

Here's the situation:

1. No files in plugin directory: multiAVCHD OK.
2. Build 2.2 files in plugin directory: OK.
3. Build 944: NOT OK

Any idea?

[qyot27]

Some programs require AviSynth's plugins folder to be on the %PATH% in order to handle the .avsi. In those cases it's the program's issue, not FFMS2's.

[Myrsloik]

I'm posting about it here as well since not everyone reads the VapourSynth thread...

Here's a ffms2 32bit test build (https://www.dropbox.com/s/6vxgt5npuyifjjw/ffms2-test1.7z?dl=1) from my own development branch. Compiled with latest libav.

I need help to test it to see so I didn't break anything for Avisynth users. If you don't test it now you'll be getting buggy Avisynth builds later.

[stax76]

Thanks for build although I could only test x64.

[stax76]

The ffmsindex memory leak is critical since a 8 GB movie causes ffmsindex to grow 8 GB memory, it's only happening with the x64 version.

[Myrsloik]

64 bit test build (https://www.dropbox.com/s/lc0x2qncwbaup45/ffms2-test1-x64.7z?dl=1). Basically the same code as the 32 bit one.

Report your results.

[stax76]

First thanks for your work and support. :thanks:

I confirm the ffmsindex leak is fixed but there is another problem, the filter reports 'No video track found' trying to open avc mkv.
