Medibuntu ffmpeg for Ubuntu 8.10 Intrepid missing

[Bill Hung]

the ffmpeg is missing from the 8.10 Intrepid
http://packages.medibuntu.org/intrepid/index.html

On the other hand, ffmpeg is there for 8.04 hardy
http://packages.medibuntu.org/hardy/index.html

Any chance of having ffmpeg listed in Medibuntu for 8.10 Intrepid?

Hi,

An "unstripped" build of ffmpeg is now included in the Ubuntu official repositories (intrepid/multiverse). You need to install the following libraries:
libavcodec-unstripped-51
libavdevice-unstripped-52
libavformat-unstripped-52
libavutil-unstripped-49
libpostproc-unstripped-51
libswscale-unstripped-0

Note that they should be automatically pulled in if you install ubuntu-restricted-extras (ou kubuntu-restricted-extras or xubuntu-restricted-extras).

They should include all necessary codecs (except amr, because I haven't had the time to add it, please open a specific bug report if you are interested by it), thus making a medibuntu package useless.

[Bill Hung (billhung)]

thanks for the quick reply.

I actually had ubuntu-restricted extras installed already. But that didn't work. I am trying your "unstripped" suggestion now.

By the way, I used mencoder from medibuntu and mencoder was able to encode in h.264, but the audio was not quite right. So I still want the ffmpeg in medibuntu to work.

Hope to see ffmpeg in medibuntu.

[Bill Hung (billhung)]

sorry, still couldn't solve my ffmpeg problem with those "unstripped" codecs.

Also couldn't get the ffmpeg to work properly by downloading the latest source and codec.
Nor keep updating the latest ffmpeg + restricted codec from ubuntu.

I will keep looking forward to a medibuntu ffmpeg release. I use ffmpeg from medibuntu on 7.10 in another PC, which worked very well for h264+aac video encoding that I do.

[Lionel Le Folgoc (mrpouit)]

> sorry, still couldn't solve my ffmpeg problem with those "unstripped" codecs.

Could you please be more precise about you issue? The unstripped variant is built with aac and h264 support enabled.

[Laurent Dinclaux (dreadlox)]

It is as simple as:

" Unknow encoder 'aac' "

Or

" Unknow encoder 'libamr_nb' "

Or

" Unknow encoder 'xvid' "

I use Intrepid 64 with all unstripped packages installed. Hate lossing functionnality on OS upgrade. Sure some things go foward but some others backward....

The correct one should be 'libfaac'.

See [*] below.

Try 'libxvid'.

Please, instead of blaming us, run "ffmpeg -formats" to find the correct
 names (it seems they have changed).

[*] AMR support is not available in the Ubuntu package, because I
haven't had the time to update the patch which allows using libamr at
runtime. There is a candidate package available at
https://launchpad.net/~medibuntu-maintainers/+archive if you want to
check it.

[Laurent Dinclaux (dreadlox)]

libfaac is ok.
libmp3lame replaces mp3
libxvid is ok

Thanks

Waiting for arm support....... I'll give your package a try

[Laurent Dinclaux (dreadlox)]

Well trying to encode an mp3 to mono for mobile phone using
-acodec libmp3lame -ab 32k -ac 1 -ar 22050

Result is a 160kbps mp3 stereo....

Mmh, then please report this bug against the ffmpeg package in ubuntu
(https://bugs.launchpad.net/ubuntu/+source/ffmpeg). Thanks

[Marius Grannæs (grannas)]

FFmpeg in main is missing h.264 encoding support.

This is a known issue:
https://bugs.launchpad.net/ubuntu/+source/transcode/+bug/276519

Can you package one with encoding support?

[Lionel Le Folgoc (mrpouit)]

Hi,

Could you try with the unstripped variant (in multiverse), as described in the second comment?
Thanks.

[Marius Grannæs (grannas)]

It is still missing.

In that bugreport I've attatched to my previous post, the ubuntu people mention that they cannot link their ffmpeg to x264, because ffmpeg is in main, while x264 is in multiverse.

(x264 is afaik what gives ffmpeg its h.264 encoding capability)

[Lionel Le Folgoc (mrpouit)]

The unstripped variant is in multiverse, and thus linked with libx264.
ffmpeg -formats | grep 264 returns something here, so this should be ok.

[Marius Grannæs (grannas)]

My ffmpeg -formats returns:

D V DT h264

note this is not the same as the package format "raw h.264", which returns:
DE h264 raw H264 video format

Maybe I'm missing something big here. Can you point me to the multiverse-version of the package, so I can test
it explicitly?

[Guillaume Martres (smarter)]

Just read https://bugs.edge.launchpad.net/medibuntu/+bug/291011/comments/1 again.

[Marius Grannæs (grannas)]

I have just done so. Still no h.264 encoding. Can you please post your output of ffmpeg -formats | grep h264 ?

I have:
grannas@hydra:~$ ffmpeg -formats | grep h264

[Lionel Le Folgoc (mrpouit)]

As I wrote several times above, many codecs have been renamed in ffmeg since the old snaphost shipped in hardy. The correct name should be 'libx264' now (that's why "ffmpeg -formats | grep h264" returns nothing useful).

[Paul Gevers (paul-climbing)]

libavcodec-unstripped-51
libavdevice-unstripped-52
libavformat-unstripped-52
libavutil-unstripped-49
libpostproc-unstripped-51
libswscale-unstripped-0

Note that they should be automatically pulled in if you install ubuntu-restricted-extras (ou kubuntu-restricted-extras or xubuntu-restricted-extras).

ubuntu-restricted-extras only pulles in libavcodec-unstripped-51, but AFAICT that's enough for x264 and xvid. Mind you, it only recommends...

[Paul Gevers (paul-climbing)]

Hmm. The above comment is not too clear. The first two parts should of course be quoted...

[Lionel Le Folgoc (mrpouit)]

Yes, you're right. IIRC, recommended packages are automatically installed for packages belonging to the "metapackages" section tough, so this should be ok anyway.

[Alex Wauck (awauck)]

If I try to install the unstripped versions, it removes the libav*-dev packages! I need those!

[Guillaume Martres (smarter)]

This is *not* a Medibuntu bug. Fill a bug report to Ubuntu, this bug report is not here to collect every problem caused by the unstripped flavour.

[Lionel Le Folgoc (mrpouit)]

Already reported as Bug #289600 btw.

[Hal Vaughan (hal-halblog)]

After reading through this, I'm still a bit confused. It's been a big help because I can use libmp3lame and finally produce MP2 files from my .mts files to put on DVDs for some friends, but the usefulness of the FFmpeg library is still quite limited. For example, I tried to us VLC to easily and quickly transcode my .mts files to .mpg and it would not work because VLC is trying to specify codecs that are either renamed or no longer existent in the repository version of FFmpeg. I also tried to transcode my .mts files to .mpg using "-target DVD" on the command line with FFmpeg and ended up with no audio. My best guess, after a lot of experimentation, is that the MP2 files have no audio playback unless the audio is in MP3 format and that within FFmpeg, if one specifies "-target DVD," that internally FFmpeg automatically uses the mp3 codec, which is not there in the Intrepid version of FFmpeg (replaced by libmp3lame).

Is it possible to put in hooks so if one specifies a codec that has been replaced that rather than giving an error, it'll automatically call on the replacement -- but with a warning message to the console? That would let VLC and other external programs that use it to continue to work with FFmpeg as they did in Hardy and before they were broken in Intrepid.

[Laurent Dinclaux (dreadlox)]

+1

[pt123 (pt123)]

I don't get this I thought medibuntu used to provide a package of ffmpeg because the one provided in Ubuntu has always pretty useless because xvid and other codecs were never enabled.

So why was this package dropped after being provided for Hardy by medibuntu?
