[gentoo-user] How to convert and watch dav video file?

[Gevisz]

I have to watch a lot of dav video files and possibly convert
them to a more common video format like avi or mp4.

What are my options?

Thank you.

P.S. My vlc does not understands this format.

Have you tried media-video/handbrake? It's straightforward to use and
comes with plenty of preset output settings.

No.

I am afraid of installing a package that is masked in Gentoo portage tree.

emerge --search handbrake
Searching...    
[ Results for search key : handbrake ]

don't use emerge -s to look for stuffs. It's slow and never shows the
full picture. Use app-portage/eix instead:

# eix handbrake
[I] media-video/handbrake
     Available versions:  (~)0.9.9 **9999 {fdk ffmpeg gstreamer gtk}
     Installed versions:  0.9.9(15:09:43 18/10/2013)(ffmpeg gstreamer
gtk -fdk)
     Homepage:            http://handbrake.fr/
     Description:         Open-source, GPL-licensed, multiplatform,
multithreaded video transcoder.


handbrake-0.9.9 works very well indeed but it's ~arch. If you don't see
it in your output, you need to --sync

Incidentally, there's nothing bad about installing that package's 9999
version. It's masked because it's in the source repo (all
cvs/svn/git/etc sources are always masked so they don't get installed
accidentally). But keeping them current is a pain.

Thank you for your advice. emerge --search is indeed very slow.

Last time, I updated my portage tree on January 11, 2014.
So, it is something different. May be, ~amd64.

Thank you for information, but so far I am trying to keep my system as
close to the main portage tree as possible and really afraid of any
masked packaged and even the packages from other overlays.

By the way, is there any way to find why any given package is masked
in the main portage tree?

Back to the main topic.

I have found out the ffmpeg can convert dav to avi but it also
outputs a lot of error messages. May be, because I use some wrong
options? I use:

ffmpeg -i input.dav -vcodec libx264 -crf 24 output.avi     

The error messages are like these:

That's what Alan said, ~arch, as shown by the ~ in front of the version
number in the output from eix.

handbrake-0.9.9 is not masked, it is keyworded, a very different thing.
Masked means there is some reason if should not be generally used,
keyworded just means the ebuild is recent and hasn't yet moved frmo
testing to stable status. It is still in the main portage tree.

> in the main portage tree?

Yes, ${PORTDIR}/profiles/package.mask contains al the masked packages
along with the reasons for their masking.

ffmpeg is a good example of user-hostile software, partly because video
encoding is such a complex subject. Mencoder suffers similarly, which is
why I suggested Handbrake in the first place. Pick your input file,
choose an output preset and hit the big green Start button.

You're being overly cautious to your own detriment. Handbrake is almost
permanently keyworded, I can't recall a time when a version was ever
marked stable. This is unrelated to code quality, it's likely to be
simply manpower (a huge thread is happening right now on -dev on this
very subject).

Handbrake works and works well. You get the same as what you'd get if
you installed it direct from the project site (or if you ran it on
MacOS). It's an app, nothing consumes it so it either works or it doesn't.

If we were discussing say dbus or apache&php putting latest unstable
package on an otherwise stable system you would indeed have a very valid
point. But this is not the case here. If ~arch handbrake needs to update
some other lib to ~arch, it won't work emerge and you'll get a very
verbose message saying why. Then you can make an informed decision.

I thought Handbrake was masked because upstream have poor packaging practices.

The source for Handbrake (I think) contains the source of loads of other libs (which you might already have installed on your system), effectively snapshotted and hard-linked to. I.E., it's a mess.

I think you might be right. Now that you mention it, handbrake sources
come with a humongous number of bundled libs. Makes chromium and
openoffice look like a walk in the park.

That used to be the case but the 0.9.9 ebuild contain this comment

 # the version 0.9.9 supports the use of system libraries.

and DEPENDS on the libraries that used to be bundled.

And it is not masked, although earlier versions were, it is just ~arch
keyworded. Earlier versions could be problematic, especially with ffmpeg
changing their API every month with a vowel in it, but now the bundled
libraries are gone, and the clashes along with them.

Have you tried viewing them in mplayer?

IMO ffmpeg or mplayer are the correct tools for conversion - my instinct says that Handbrake is not.

In another comment you report some error messages. I think your video files are recordings created by a handheld video camera - it's possible there are bugs in the video it creates.

At least if you use ffmpeg you'll be aware of these warnings - if the converted video plays, then fine, but at least you have the opportunity to tweak the settings and reduce the errors to the minimum. I think a GUI app like Handbrake will only hide the errors from you.

Yes, I have just emerged it (with the default use flags)
but it does not play dav video files properly.

I think you are right.

Actually, I had the same thoughts but was not sure.

The videos are produced by a surveillance digital video recorder.

avi files created by ffmpeg are played ok both by vlc and mplayer.

So, I think that I have to convert them first and then use vlc.

Thank you for your help.

And thanks to all who replyed to this thread, as well. :)

In the past I've found the mplayer / mencoder mailing list helpful. The devs there might even be interested to see a sample file, to see if they can better support it.

TI has a proprietary h.264 implemetation, encoding and encryption technology
built into various processors and DSPs, know as DaVinci [1]. The proprietary
videos are stored in a propriatary format. They provide a high-performance
TI DaVinci series DSP H.264 video. Many asian manufacturers
use a bastardized versions known as h.264-lite (AVCHD lite). Acutally,
the chineese video offering is a plethora of divergence and your experience,
vendor to vendor can vary widely. TI is the 800 lb gorilla in the h.264
space, probably providing the raw technology to 80% of the manufactures
of anything that runs h.264, or licensing via their patents on h.264.

There are tools/software to convert these video clips to other formats,
as you like, under windows, readily available[2]. 

You run into a lot of bullshit, deception and re-branding in this effort,
both from the camera and headend (storage) devices, as well as the snakes
that license these offering. All pay homage to MPLA (bastards). [3] TI
is one of the largest h.264 patent holders that MPLA enforces.

Here is an interesting discussion about a linux SDK [4].

A posible slick (but expensive) way to do this is purchase an expensive
package, like Sony's Vegas Pro12. I hear that is does everything, but,
I have not tried to work with .dav files.......

I have not tried the latest offering of handbrake, but since it is voiced
to be stable and capable, I am interested in this possibility too.
