ffmpeg.exe encoding in VFW as MEncoder?

[marcorocchini]

Hi

in MEncoder I can encode using FOURCC of windows:

mencoder c0020.mxf -ovc vfw -xvfwopts codec=digivcap.dll -nosound -o output.avi

and in ffmpeg is possible this, also with an older version?

thanks

I can encode using FOURCC of windows:

I assume, you ment, you can encode using vfw (video for windows) encoders.
(FOURCC is simply short for "four character code" - an identifier for a video codec, compression format, color or pixel format used in media files.)

and in ffmpeg is possible this, also with an older version?

No, ffmpeg has no (and never had) an option to use vfw encoders (or decoders), I'm not even sure that mencoder still supports the usage of vfw encoders, haven't used vfw codecs for ages. (+ afaik. even if mencoder still supports it, one would still need to create a mcf-config-File using vfw2menc)

[El Heggunte]

Mencoder still supports the VfW dlls, and at least on Windows, there is no need to mess around with vfw2menc.exe.

[Selur]

@ElHeggunte: afaik vfw2menc is needed (for the configuration) if you want to use a vfw encoder, if you want to use a vfw decoder it's general characteristics either need to be included in the internal or external codecs.conf infos.
That aside, the main point was, that ffmpeg doesn't support either vfw de- or encoding.

If you want to run a 2-pass encode, yes, otherwise, no,
since the encoder settings can be read directly from the Registry

Incorrect --- the main point is, the OP asks the wrong question in the wrong time

[Selur]

since the encoder settings can be read directly from the Registry

Ah, okay, I assumed that the OS wasn't Windows, so no Registry in scenario.

[marcorocchini]

So can I use ffmpeg to encode with a vfw codec?

[Selur]

No, we were just discussing whether it is still possible or not with mencoder.
The statement:

No, ffmpeg has no (and never had) an option to use vfw encoders (or decoders)

is still valid.
