mpg/avi editor for linux?

[mindows]

can someone recommend me a mpg/avi editor for linux? i just want to cut a few frames out of avi & mpg movies. what do ppl use?
thanks,

[okram]

There is the heavyweight cinelarra published by heroinewarrior http://heroinewarrior.com/cinelerra.php3, but that is probably much more than you need.

for dv encoded avi there is the excellent kino http://kino.schirmacher.de/

And then there are the two superb command line utilities mjpegtools http://mjpeg.sourceforge.net/
and transcode http://www.theorie.physik.uni-goettingen.de/~ostreich/transcode/html/misc.html
that you can use for converting between formats and very simple editing (cutting, pasting).

The commercial program MainActor http://www.mainconcept.com/ is quite good too and has a free demo.

There's a great little prog called avidemux.
For those who know virtualdub for win, it's THE program they're looking for.
I'v committed an ebuild, bug 7973.
I will be in the tree in 1.4 final they say.
You could check it out it you like, just dl the ebuild and put it in your PORTAGE_OVERLAY dir.

cinerella didn't compile well on my machine. complained about not finding libquicktime.a. i think kino compiled successfully after getting a few dependencies, but segfaulted just about every time. do i need to patch my kernel to support the libraw? i'm using the 1.2 gentoo source.
if avidemux is going to be in the 1.4 tree, does that mean it wouldn't work with 1.2?

[mean]

The strict minimum to build avidemux is
- Gtk & Gdk 1.2
- Divxencore & divxdecore

So try zypher ebuild, and if for whatever reason it fails, build it manually
with ./configure --disable-warnings && make

I've downloaded this app from the author's web site, r18. I installed it (./configure, make, make install) it runs, loads AVI (divx) files, and plays them, but when I try to save as MPEG1 (VCD) it pops up a message box which states "Not compiled with MPEG output support.)

I have libmpeg3 installed. What else do I need to do?

<edit> OK, emerged mjpegtools, now configure states it has mpeg support... will test in a few minutes. Also emerged mad, and ffmpeg. mad is now seen by ./configure, but it still does not see ffmpeg. Going to install xvid next.</edit>

er.. uhm.. so, does k3b have VCD support yet? How would I go about burning a VCD with linux? I have xcdroast, gtoaster, and emerging k3b right now.. not sure which app I will use, so I'm testing a whole bunch.

BTW, after emerging libmpeg3, mjpegtools, and mad, avidemux now works properly (had to rebuild/compile it of course.)

Well, now I have arson installed as well. Also merged VCDImager. Still getting an error when I try to burn VCDs with arson =/
BTW - I can write audio and data CDs with all of the programs.

Ahh well.

Any help? anyone? anyone at all?

[Mr. Pointy]

If you've sucsessfully used vcdimager and have the created videocd.bin and videocd.cue ( or whatever they're called) use cdrdao.

for vcd:

cdrdao write videocd.cue

for svcd:

cdrdao write -t svcd videocd.cue

there are other options related to cdrw drivers and speed etc that you can put on the command line or in a config file here's mine:

~/.cdrdao

write_device:"/dev/cdrw"
write_speed:12
write_driver:"generic-mmc"
read_driver:"generic-mmc"
read_device:"/dev/dvd

[mean]

If you want to convert divx to VCD there is a meta filter called VCD-Res that will adjust the size automagically to VCD compatible one.

Using mjpegtools to create VCD works but it is painfully slow

I'm looking for a faster way.

For ffmpeg when installing it, don't forget to use --enable-shared
If already done, copy avcodec.h common.h (bswap.h ? depending on you build) to /usr/include/ffmpeg.

If you do editing (cut etc...) i strongly recommend you disable misc->turbo (ffmpeg).

[zypher]

I compiled ffmpeg by hand and used --enable-shared.
That did the trick for me.
BTW, be sure to start avidemux from an xterminal, the console-output is often useful.

nice! thanks everyone, I will give all your suggestions a try and report back with my results (compiling the CVS of ffmpeg.)

<edit>
Ack, the ffmpeg FAQ states:
FFMpeg Frequently Asked Questions


1) ffserver doesn't not work.
ffmpeg development is now concentrated on the codec and format
handling. New developments broke ffserver, so don't expect it to work
correctly. It is planned to fix it ASAP.

Maybe I should stick with the ebuild.
</edit>

just a quick note: arson automatically detected VCDImager after I emerged it, but it still fails after it writes the xml file. I'm not exactly sure what the error message is since I haven't messed around with it for a few days. Will post more details soon.

Also, this may be a silly question: Does CPU optimization (CFLAGS, etc) improve decoding / encoding performance? I currently have not set these flags, just have CHOST set to i686 (I have an AMD Duron 950mhz.) I hope the answer is a minimal increase in performance because I'm not sure I feel like recompiling my whole system =)

OK, avidemux now sees ffmpeg as well! thanks =)

One other thing I noticed:

[thorne]

More updates...

1. While trying to convert divx to vcd, I only get video in the output file, no audio. I'm using ffmpeg. This is related to the fact that it did not find mp3lame, right?

2. Should there be a difference in speed while using ffmpeg compared to mjpeg? I see no difference at all. Both say about ~300 minutes for a 700MB divx file.

For arts, it is due to the dumb way configure is build.
It does not use the same flags for C and preprocessor
In the config.log you should have something about
arts.h ok
arts.h rejected by preprocessor, no ?
Did you use --with-extra-includes=/usr/kde/3/include --with-extra-libs=/usr/kde/3/lib

For ffmpeg and vorbis, lame -> Better that way else you will have dependancy problem.

For mpeg-1 output, it is normal you get only the video.
To have audio, select audio->process mode, normalize (48->44 if needed) and file -> save audio

Then toolame /tmp/audio.wav -e -b 224 -ms /tmp/audio.mp2
Then multiplexe audio.mp2 and video.m1v to have your final mpeg file.

It works but it is painfully slow. I have success using TMpgenc with wine.
It may be a solution if you don't mind wine.

Mjpeg is fast but the size is not the same (nor the quality)
Try on a 5 mn sample both and look at the size

[mean]

For arts
export LDFLAGS="-L/usr/kde/3/lib"
./configure --with-extra-includes=/usr/kde/3/include --with-extra-lib=/usr/kde/3/lib --disable-warnings

And it should be detected

[thorne]

[mean]

For arts please try http://fixounet.free.fr/avidemux/configure.gz
with the LDFLAGS and --with-extra...

It should work
