ffmpeg2theora with derf's theora codec support

bond · 23rd July 2005, 13:49

j^ has ported his ffmpeg2theora tool to be able to be used with derf's theora encoder which makes use of the full features theora offers and not only the ones which were also there in vp3 (as supported in the reference theora encoder)

the sources can be found here: ffmpeg2theora-exp and derf's encoder

anyone wanting to make a compile for testing this?

You can get one here: http://4nykey.nm.ru/bin/ffmpeg2theora-svn.exe

bond · 23rd July 2005, 22:22

thx, but are you sure that this is with derf's encoder? did you do the compiles?

ak · 23rd July 2005, 22:28

Well, yes, it says 'ffmpeg2theora-exp 0.13-svn' and oggs it produces decodable only with libtheora-exp. If I upped the right one that is

thanks a lot!

I just cant get ffmpeg2theora to crop my clip

ffmpeg2theora -h states:

Code:

ffmpeg2theora-exp 0.13-svn

 usage: ffmpeg2theora-exp [options] input

Output options:
	 --output,-o		alternative output
	 --width, -x		scale to given size
	 --height,-y		scale to given size
	 --aspect		define frame aspect ratio: i.e. 4:3 or 16:9
	 --crop[top|bottom|left|right]	crop input before resizing
         ...

Here a list of commands that I have tried, all in vain.

Code:

::ffmpeg2theora --crop=8:8:8:8 -o out.ogg prodigy90_med.mpg
::ffmpeg2theora -croptop 32 -cropbottom 32 -cropleft 32 -cropright 32 -o out.ogg Suzuka.avi
::ffmpeg2theora -o out.ogg Suzuka.avi
::ffmpeg2theora -i Suzuka.avi -croptop 32 -cropbottom 32 -cropleft 32 -cropright 32 -o out.ogg 
::ffmpeg2theora --crop 8|8|8|8 -o out.ogg Suzuka.avi > out.txt
::ffmpeg2theora --crop 8 | 8 | 8 | 8 -o out.ogg Suzuka.avi > out.txt
::ffmpeg2theora --crop [8 | 8 | 8 | 8] -o out.ogg Suzuka.avi > out.txt
::ffmpeg2theora --crop [8|8|8|8] -o out.ogg Suzuka.avi > out.txt
::ffmpeg2theora --crop=[8|8|8|8] -o out.ogg Suzuka.avi > out.txt
::ffmpeg2theora --crop=[8 | 8 | 8 | 8] -o out.ogg Suzuka.avi > out.txt
::ffmpeg2theora --crop 8:8:8:8 -o out.ogg Suzuka.avi > out.txt
ffmpeg2theora --crop=8:8:8:8 -o out.ogg Suzuka.avi > out.txt
PAUSE


E:\Rechner\Neu\Import\ffmpeg2theora>ffmpeg2theora --crop=8:8:8:8 -o out.ogg Suzu
ka.avi  1>out.txt
ffmpeg2theora: ambiguous option -- crop
Input #0, avi, from 'Suzuka.avi':
  Duration: 00:24:03.8, start: 0.000000, bitrate: 1018 kb/s
  Stream #0.0: Video: mpeg4, yuv420p, 640x480, 23.98 fps
  Stream #0.1: Audio: mp3, 48000 Hz, stereo, 128 kb/s

  Resample: 48000Hz => 44100Hz
      0:00:00.04 audio: 0kbps video: 7480kbps

The output shows ffmpegg2theora`s typical error message, if ffmepg2theora starts up at all. As one can see, the source is modolo 16, and encoding without cropping works just fine. But I want to encode some TV-captures with bad edges that need to be cutted badly.
Can anybody please enlighten me, how to set cropping values.

Hellfred

EDIT:
Googling for "ffmpeg2thora crop" brought up the solution:

Code:

ffmpeg2theora --croptop 16 --cropbottom 16 --cropright 32 --cropleft 16 -o out.ogg Suzuka.avi > out.txt

how's the quality compared to "reference" theora ?

Sorry, that i do not know, as i never used that one. But just try yourself. Win32-binaries are available for both and the usage of ffmpeg2theora is quite simple. I have to hunt bugs right now.

hellfred, i also struggled with its crop option and this is how it works:

Code:

--croptop 82 --cropbottom 78

i would say its worse than the reference one

but derfs decoder is both faster and complete

hellfred · 29th July 2005, 08:41

Yes, last night I encoded the same clip already used for testing derfs encoder with standardt ffmpeg2theora, featuring the mmx-enhanced reference encoder. Derfs encode was a little bit sharper (only set quality with -v 10 to max) but had much more block artefacts e.g. in the sky and more ringing. Source was a vob that needed to be deinterladed (-d).

PatchWorKs · 29th July 2005, 09:48

Why not porting these 'enhanced' features to ffvfw ?

...FairUse is going to become the 1st DVD Backup tool that encodes by it.

dimzon · 29th July 2005, 10:36

how about AviSynth support???

hellfred · 30th July 2005, 08:54

Hi
I have made yet anoter test comparing the two ffmpeg2theora. This time the source was a video clip, captured with my analog tv-card. The Source has only low quality, was captured als lossless MJPEG and was being properly deinterlaced croped and resized (modolo16) before encoding. Deinterlacing was done using kerneldeint.
Again, derf showed much more blocks as the mmx-enhanced reference encoder.

you can feed ffmpeg2theora with .avs via akupenguin's avs2yuv tool

ffvfw is not existing anymore

and ffdshow already includes the theora reference encoder and can even output to .ogg! (yeah .ogg, not .ogm)

What you mean ?
It's present in the last ffdshow build.

celtic_druid · 5th August 2005, 10:06

Well not exactly. There is a VfW wrapper called ff_vfw, but ffvfw as a project as said doesn't exist any more... There is just ffdshow.

PatchWorKs · 5th August 2005, 13:04

oh, well... you mean they merged. I know.

Any way to feed ffmpeg2theora with .avs and have sound?

celtic_druid · 18th March 2006, 16:15

Well I guess you could pipe from avs2wav to ffmpeg.

Sirber · 18th March 2006, 17:21

Is there a way to pipe video and audio from .avs at the same time?
