Avisynth, FFMPegSource, DGAVCDecode and some other basic questions

[Maikeru-sama]

I wanted to ask some basic questions.

I am only familiar with AVISource and DirectShowSource, but want to become familiar with others. Here are my questions:

1) How do you disable the audio when using FFMpegSource and DGAVCDecode?

2) When using DGAVCDecode, do you have to use a dga as your source can you use the traditional file extensions (avi, mkv, ogm etc etc)

3) When using an Avisynth Plugin, how come some of the Plugins have to be in the AviSynth Plugin Directory and others can be anywhere? Is it based on how the software was developed?

2) When using DGAVCDecode, do you have to use a dga as your source can you use the traditional file extensions (avi, mkv, ogm etc etc)

only dga index files. from loading input into DGAVCIndex.
valid inputs for DGAVCIndex are elementary h.264 streams or h.264 transport streams.
so...
for all the formats you mentioned, demuxing comes first.

1) How do you disable the audio when using FFMpegSource and DGAVCDecode?

there is no audio with dgavcdecode.
the audio is off by default with ffmpegsource.

3) When using an Avisynth Plugin, how come some of the Plugins have to be in the AviSynth Plugin Directory and others can be anywhere? Is it based on how the software was developed?

all plugins can be anywhere.
(* although some may depend on libs that need to be placed in your path)
plugins in the plugin directory are autoloaded, ie loaded each time you call on a script.
and are available to you to call with a simple: plugin()
plugins external to the directory (and c plugins) have to be manually loaded in each script,
ie loadplugin("plugin.dll"), and then a call to it: plugin()

1) How do you disable the audio when using FFMpegSource and DGAVCDecode?

FFmpegSource is for video only, and FFAudioSource is for audio

The difference between DirectShowSource is because it deals much better with different codecs configuration, it works much like a Graph for render any movie directly connecting pins, much like FFDSHOW.

Not all people uses FFDSHOW, but rather they use CCCP which for me is much better because it is a light version of FFDSHOW and just works fine, or they use CoreAVC. FFDSHOW mega pack can ruin your PC if you don't know how to configure and deal with it...and few people knows about it

It easy to figure that out when there is 1000 computers with different codecs configuration : they can play, therefore they demand a successfully conversion....they just don't care about anything

speed, and one-click conversion, is just what they want

2) When using DGAVCDecode, do you have to use a dga as your source can you use the traditional file extensions (avi, mkv, ogm etc etc)

for DGAVCDecode, never used it, FulciLives would answer

3) When using an Avisynth Plugin, how come some of the Plugins have to be in the AviSynth Plugin Directory and others can be anywhere? Is it based on how the software was developed?

They can be automatically loaded, or manually

Since there is many plugins, each application loads manually the plugins by their own way

Good stuff gents.

One final question (I didn't ask because I need to know the DGA question), is there a command line tool that will encode files to DGA?

[45tripp]

index you mean.

dgavcindex has a cli mode.
read the manual

You're not encoding your files to dga, all you're doing is creating an Index which points to your h264 source file. When you load that index (the dga file) into Avisynth (via the DGAVCsource command) it will provide the necessary information for VirtualDub (or whatever app you want) to convert to another format.



Download the avchd_convert zip file in this thread if you want some help with the command line syntax of DgavcIndex

@Soopafresh, I will download that when I get a chance and of course, ask questions, if I have any.

Also, finally got around to downloading the FFMpegSource Plugin and I have encoded about 5 MP4 files in a row via Avisynth and CCE has not crashed yet .

So it looks like I will be using the FFMpegSource for files that are of the same criteria of the sample most in here is familiar with.

Also, does anyone know if the developers of Quenc frequent this forum? I am in the process of writing a Batch front-end to it, which I would like to share with the forum and I would like to be able to program the "pulldown" option they have in their application with it but there doesn't seem to be a command line argument for it in the quenc notes.

Based on my limited knowledge, it seems like Quenc internally determines if you need it, not sure though.

But anyway, I don't want to derail this thread, so I am going to split.

[45tripp]

no,
the development thread is at doom9.
dragongodz has been inactive for a few months.

do it for hc instead...

no it doesn't
