Ubuntu Multimedia :: Mencoder X264 Encoding Broken In Maverick?
Oct 16, 2010
I recently upgraded to Maverick and am loving it. Converting over my various scripts to work on the new box I notice that my video trascoding script, which uses mencoder to re-encode video as h264, now does not work.
Code:
mencoder $inpfile -oac mp3lame -lameopts vbr=3:q=3 -ovc x264 -x264encopts crf=22:threads=auto:subq=4:bframes=2:b_pyramid:weight_b:turbo=1 -ofps 25 -o $outfile
For a long time this has worked just fine but the command basically bombs out every time with
Code:
FATAL: Cannot initialize video driver.
I tried using the medibuntu mplayer/mencoder but still no dice.
Does anyone know how I can get this important functionality back?
I've multiple jpegs uploaded form IP cam via FTP, I use mencoder to periodically pack them into single avi file, problem is that sometimes one or two jpegs submitted by cam are broken, and this make mencoder exit, without producing movie
I have a load of XViD videos and I want to re-encode them into x264 - when I say a load, I mean over 300, anyone have any programs they reccomend to do it?I want to make them into those "future-sized movies" (700mb --> 300mb, 170mb --> 95mb, 350mb --> 150mb), what settings should I use? I want to keep the quality of the originals intact, along with the video sizes if possible, but if not, I don't really mind, just make them smaller. Here are the settings some people use in windows:oh yeah, one last thing - fast encoders please, I know it'll take a good while, but I want it to take as little time as possible please
I have been using Avidemux to encode edited video using x264 and the mp4 container for most of my videos. My PCs are not new, using single-core AMD Athlon processors.
In 9.04 and 9.10 (Linux Mint), encoding speeds ranged from 7 to 10 frames per second. In 10.04 these dropped down to less than 2 frames per second.
I booted back into Linux Mint 8 (9.10) and the same video encoded at the previous 7 to 10 fps.
I tried with other videos in different formats (mpeg2 and VOB). The results were the same - 10.04 was extremely slow encoding x264 but Mint 8 was "normal" at 7 to 10 fps.
With a dual-core notebook, however, the encoding speeds ran at 8 to 14 fps in 10.04.
Was 10.04 optimized for dual and multi-core at the expense of single-core? If so, is there a way to restore "single-core optimization"?
I use the script h264enc (installed from the repos) to encode my dvds into avi and mp4. It was working flawlessly under 9.10, now I get the error that MEncoder doesn't support AAC encoding? I have installed all the restricted drivers and I can play dvds, mp4's, .
The version of mencoder I currently have installed segfaults (immediately) when you ask it to convert x264-encoded MKVs to another format. One sample command-line would be:
Code: mencoder -nosound -ovc libdv Puella_Magi_Madoka_Magica_720p_GG_-_06.mkv -o a.avi This produces the following output: Code: MEncoder 20110702-4.5.2 (C) 2000-2011 MPlayer Team success: format: 0 data: 0x0 - 0x1c43987e libavformat file format detected.
[Code]...
Incidentally, I'm wondering if the version of FFMpeg that the MPlayer configure script downloads might be at fault. The slightly outdated FFMpeg I installed from SBo (6.1) does not crash when converting the same file. And no, I can't use either Alien Bob's Mplayer build or the MPlayer binaries included with Slackware. Neither is built against either libdv or x264. I need libdv as an output codec.
I recently tried to upgrade my graphics card. I had an Intel GMA 950, and upgraded to a PNY Nvidia GEForce 8400GS with 512 DDR I installed the card, and was unsuccessful in getting it to work, but while using the onboard graphics I updated the drivers in ubuntu to use the Nvidia proprietary drivers. I went into a cycle of rebooting and fiddling. booting into Ubuntu was successful with the onboard card, however I only got a command line. I used nano to change my xorg.conf from saying
Driver "nvidia". I simply deleted this portion in the hope that X11 would simply think on its feet. Onboard graphics wouldn't deliver any X session after that. I eventually got the card to work after futzing with the BIOS settings, however once I tried to boot, I got the error "init : ureadahead main process (264) terminated with status 5" after numerous upgrades, my GRUB menu has several kernels, however none of them would boot properly, including recovery sessions.
I decided to boot into a livecd to edit my xorg.conf in a Live environment, but I was unsuccessful, the LiveCD (simply Maverick Meerkat, after trying Karmic Koala) got stuck in a loop of not being able to detect media in /dev/sr0, which is very puzzling. So now I'm stuck with a computer with a functioning video card and nothing else.
I have installed a Maverick machine and was utterly annoyed by the removal of XDCMP chooser in GDM (why in the world one would do this?!). The common wisdom seemed to install xdm or wdm instead.
I did try both of them (dpkg-reconfigure gdm and select xdm or wdm), BUT none is working. The only relevant point I found in xdm log: it fails to start X correctly, where spawned X instance claims that no usable screens can be found.
At the same time, gdm starts just fine.
Was anyone successful in getting any of these running?
So for the last, oh, three or four hours now, I've been trying to get videos to play properly in Ubuntu. I have the default player, I have vlc, I (apparently) installed mplayer, but it won't play anything at all.
I was having horrible screen tearing with standard definition .avi's in vlc, fixed that by setting vsync in catalyst control center to always on or whatever it is.
Now, I have tried to run a 720p x264 video. It PLAYS, but not well. Audio is fine, however video is all jerky in VLC, and in Totem it's just a mess of screen tearing (although the video does no jerk on that player).
I have just spent HOURS trying to get VIDEOS TO PLAY. This makes no sense. Playing a video should be the simplest thing in the world for any OS to do, but with Ubuntu it is like pulling teeth. I have NEVER been so frustrated while using a computer. What is going on here?
BTW, I installed every single thing needed to use mplayer but it still does not work. The player comes up but will not play any type of file.

I was really enjoying Ubuntu until I got around to trying to watch some videos. Now I am maybe minutes away from going back to vista. At least on there I can watch full 1080p videos if I want with no problems.
My totem crashes after several seconds of playing x264 .mkv files. Plays everything else fine (and my HD content better than .vlc so I'm not interested in switching). In terminal, the only output I get is 'Aborted'.
I am trying to compile OpenCV 2.0 with ffmpeg (with x264) support on my Ubuntu 11.04 64-bit machine. (Since I want to use the binaries provided by other developers, I have to use opencv 2.0 version)
I followed the guide from: [URL] to compile x264 and ffmpeg manually, and succeeded.
Then I followed the guide in the INSTALL file provided by the OpenCV 2.0 package. I use CMake to configure and generate them, and use "make" command to try compiling. However, I got the following error report, which haunted me for almost half a week.
When booting from the netbook USB, there are two wireless connection stages:
the first appears at the "TRY/INSTALL" selection screen, and after supplying the keyring password, the connection appears to succeed.
the second appears on the desktop, after selecting "TRY"; the keyring dialogue appears & seems to work, but then the network login dialogue pops up, and refuses to connect.
Both my Acer machines connect to the same AP under Maverick and the EEE PC works in Lucid.
I'm using openSUSE 11.2 64bit in Dell E6400 with Intel video chipset. I can play x264 720p files without any problems in Windows 7, but in openSUSE, I could play it in Totem, but it is very slow (lots of stopping).
In addition, in songbird, if I use the mediaflow add-on,the scroll becomes really sluggish.
In general, I feel like openSUSE is showing less ram usage but higher CPU usage than Windows 7. Is my video card driver is messed up? I really like openSUSE a lot but so it is disappointing....
I've probably exhausted all possible ffmpeg argument combinations for encoding with a libx264 codec - none worked, the codec always either segfaults or tells me incorrect parameters. I've installed, uninstalled and re-installed all available versions of the codec - no difference. Did anyone have any luck with it? Are there any tricks or conflicts in different arguments? Does the input file have to be in any particular container/format/codec for the x264 to work on?
My examples: >ffmpeg -i video.mpg -vcodec libx264 video.mkv >... Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height >ffmpeg -i video.mpg -vcodec libx264 -b 4000 -s hd1080 -f h264 video.mkv Same error If I use any other codec, they all work fine. give a working ffmpeg arguments example,
I'm trying to convert a video in .ogm format to .avi format so I can stream it to my PS3 via uShare. I'm using Mencoder and the following command to do it (to transcode the audio from vorbis to mp3 and the video from mpeg4 to xvid):
Code: mencoder input.ogm -oac mp3lame -ovc xvid -xvidencopts pass=1 -o output.avi.The only problem is, the video contains 2 audio streams - one Japanese and one English. Needless to say, I need the English one. The above command only seems to transcode the Japanese audio though!Here's what ffmpeg has to say about the input file:
what I can do to specify the correct audio stream to encode? Also, how can I keep the bitrate the same as the output.avi seems to default to 96kbps?I'm not sure which audio stream is which but a little trial and error will sort that out in no time.
So I typically use cat to put my avi files together.. but today I figure lets see about ripping over so I can watch on my Droid.
As nobody has a xvid or vlc player on the droid (yet.. coders are doing alot for Android ya know) I will have to convert the video down and change the format.. So.. can anybody tell me a mencoder command line directive to get as close to this as possible (I found ipod settings leave the actual video lacking).
Video Format MP4 Encoder H.264 Resolution 854 x 480 (or 720 x 480; 480 x 320; 320 x 240) Frame Rate 12 fps - 30 fps
Using Miksoft's Mobile Media Converter, and I cannot convert files to MPEG4.[URL]Converting to MPEG1/2 works fine, but trying to convert video for my son's PSP always produces an error. Here's the output:
I am working in a script I have, to capture video with sound from my capture board, wich is a clone of the pico2000. This script was working in Ubuntu 9.10 untill I reformated my machine and instaled the Ubuntu 10.10, 64 bits. The machine is an AMD Athlon II, 2.6GHz with 3 GBytes of Ram. The former script was:
I'm doing a little python app for encoding .avi from dvds. I know there are a few really good applications out there that do the same thing but I wanted something simple with less faff. The application has 3 settings: Fast, Medium, and Slow. These are for the varying quality rips. For file format I was thinking either lavc or Xvid.
So my first question is, which is better? I really don't know anything about it and I haven't found a decent site that compares them. And secondly what are the best settings for a DVD rip for a Fast Rip, a 'Best of Both' Rip, and a Best Quality Rip? If I've missed any factors in this, please let me know, I'm new to the DVD ripping game. I have no intentions of distributing the movies, they are for my own uses.
I'm trying to convert my screencast to an .avi file, but when I open it... the commentary track is waaay out of sync. No matter which codec I use, it will not stop dropping frames!
I have a video that is currently in .mkv format, and I need it in .avi, however, when I attempt to convert it with MEncoder, it cannot find the video. (Please note this is my first attempt to convert anything with MEncoder, or convert any video on Linux). What I entered and my results are as follows -
mencoder Pocketful_Of_Rainbows.mkv -o Pocketful_Of_Rainbows.avi -ovc xvid -oac mp3lame MEncoder SVN-r29237-4.4.1 (C) 2000-2009 MPlayer Team File not found: 'Pocketful_Of_Rainbows.mkv'
I want to try encoding some videos with Dirac. I was told on another site that I have to build mencoder with Schroedinger support if I want to do this with OGMRip. I have installed the libschroedinger package installed. How do I buld it with mencoder?
Is the motion compensation deinterlacer missing in Ubuntu's Version of Mencoder?
mencoder -vf help doesn't show it (I guess this means it's not installed...), although mencoder's man pages do have an mcdeint entry.
I have those versions installed:
Code:
I first tried the Versions shipped with Ubuntu Lucid Lynx, then I installed them from the Medibuntu repositories. Both without any success. Does anyone know, how to enable mcdeint support? Is there a repository or something I could add to my sources?
I have been doing some very basic editing in Pitivi and how to get it to encode to X.264. I'm encoding to 480p and I was wondering how do I change the setting to make make it encode to X.264 and look good at small or ok file sizes. I will be uploading these to ..... and want them to look sexy.
And if X.264 can't encode to X.264 then at lest how do I turn the quality up in the formats that it does support.
