Ubuntu Multimedia :: Very Slow X264 Encoding Using Avidemux In 10.04
May 8, 2010
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 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 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?

First and foremost is Avidemux. Somewhere between Fedora 11, 12 and 13 Avidemux lost the capability to encode audio streams in AAC format. I've installed all pertinent packages for it and for AAC, and even though AAC is available to other programs (Banshee, SoundJuicer, etc), alas it is not in Avidemux. I read somewhere that since the newer version of Avidemux now uses a plug-in architecture, support for a lot of formats might be missing as they get ported.
I use Avidemux as usually I rip my DVDs into .mp4 files which I serve up from a Linux box at home and stream them to my PS3, or simply to load a bunch onto my laptop to watch on the move or when I'm on call at the hospital (like I am right now)...
Kind of related to this that I remember not too long ago, I was able to convert a DVD into PSP's mp4 format from DVD::Rip, IIRC directly from the application, but last time I used it, it only seems to have support for AVI, OGM and MPEG container formats. Maybe somthing changed along the way that I'm not aware of.
It looks to boil down to the fact that the package avidemux-plugins from RPMFusion is missing the necessary plugin... I'll go check why is that.

I'm using using ubuntu 11.04, and im using Avidemux (GTK+) whatever date that is, got it a couple days ago from the software center.
I attached some .a/s/s subtitles to the video, and the preview looked great. Encoded the video, and the audio plays like two times faster than the actual video, so by about halfway through the video, the audio is done and im left in silence with the video still going.
I set the video to MPEG-4 AVC, attach .a/s/s subs, leave audio alone, and encode using default option (Single pass-quality quantisizer)

under avidemux-qt, the videos play and encode w/out any audio output, and audiodevice is set to "dummy" and cannot be changed. but avidemux-gtk has no problem w/ audio playback.Is this an application specific problem, and if not how do i configure phonon to fix this issue?

Since upgrading from 10.04 to 10.10 (through the update manager) my previously well working avidemux now will not even start. here is the output from the terminal.
Code:
*************************
Avidemux v2.5.2
*************************
http://www.avidemux.org
Code : Mean, JSC, Gruntster
GFX : Nestor Di , nestordi@augcyl.org
[Code].....
I have unistalled and reinstalled avidemux with the same results. I have also uninstalled the ffmpeg, mencoder, and medibuntu codecs and reinstalled, however, I am getting the same terminal output and the same results.

when editing an mp4 file from videos with avidemux, the editing works perfectly but the resulting video sound is speeded up but the image runs at normal speed. the resulting mess is out of synch video/sound.

I eventually did buy a Terra HD from Zareason that I love, but I cannot get it to do my video editing of Flip Mino home videos. I know the machine is capable. It plays bigger AVI files without any problem. For sound it uses the Realtek chipset. Samples of the .avi Flip Mino videos are here. A nice short one for experimenting with is 2.3 MB, here. According to Avidemux, the Flip Mino videos have the following video properties...
Codec 4CC: XVID
Image Size: 640 x 480
Aspect Ratio: 1:1 (1:1)
Frame Rate: 30.000 fps
and the following audio properties...
Codec: MSADPCM
Channels: Mono
Bitrate: 22179 Bps / 177 kbps
Variable Bitrate: No
Frequency: 44100 Hz
My goal is simply to trim the beginning and end to get the best segment in each home movie. Avidemux worked great on my old machine as long as I changed the output audio format to MP3(LAME). But Avidemux is not working and wants to know all sorts of things about devices of which I am ignorant. The default settings must be wrong since the audio playback is choppy and usually the video saves to a one-frame broken file.
I also tried Openshot and it has no device preference issues. However, I am ignorant of how to make it save the videos properly. It wants to "export" the video using all sorts of options, none of which are simply "use the setting for the only track". Based on the 640x480 size I tried some Square NTSC tests but the exported file was always much too big -- usually larger than the untrimmed original!
Also, Openshot appears to lack a keyboard shortcut or button for "move the beginning or end of the clip back or forwards one frame". Is it really expecting me to use the mouse to position the clip's borders precisely? I have no vested interest in which software is used. Nor do I care about the resulting file format as long as it is neither wastefully large nor senselessly abandoning quality. I just want to share my home movies with friends and family.

I installed avidemux so I can split a video file. However avidemux doesn't show up on the menu. It should appear in Applications->Sound and Video but it's not showing up under any of the menu items. When I go to Ubuntu Software Centre it shows that avidemux is installed. How do I find it so I can run it? I'm running Karmic.

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.
My system specs:
2.2Ghz dual core (intel)
3gb ram
1GB radeon hd 4650 vid card
asus ipibl-lb mobo
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.
Code:

i bought an obscure video/mp3 player from china recently, and one day, i managed to use AVIDEMUX to succesfully transfer video to it. However, i dont remember the settings AT ALL. I open the working video file with AVIDEMUX, and check out the properties, but there is option in the lists to the left to convert to the video type that is open. Is there anyway to export the video properties, then convert any video, to those parameters?

In newer versions of Avidemux wrong parameters are set when choosing "Sony Playstation Portable" from the Auto menu. The PSP doesn't support more than 2 reference frames or 8x8 DCT Transform.
This is how you can fix it. Backup the original file
Code:
sudo cp /usr/lib/ADM_plugins/videoEncoder/x264/Sony PlayStation Portable.xml /usr/lib/ADM_plugins/videoEncoder/x264/Sony PlayStation Portable.xml.org
Edit the file
Code:
sudo gedit /usr/lib/ADM_plugins/videoEncoder/x264/Sony PlayStation Portable.xml
Change this line

I use ffmpeg to covert video files for the net.
Code: Select allffmpeg -i infile -vcodec libx264 -vpre ipod640 -b 250k -bt 50k -acodec libfaac -ab 56k -ac 2 -s res.mp4
which works good. I was wondering if I could use larger resolution presets, but
find /usr -iname '*.ffpreset' only gives
#/usr/share/ffmpeg/libvpx-360p.ffpreset
#/usr/share/ffmpeg/libvpx-1080p.ffpreset
#/usr/share/ffmpeg/libx264-ipod320.ffpreset
#/usr/share/ffmpeg/libvpx-1080p50_60.ffpreset
#/usr/share/ffmpeg/libx264-ipod640.ffpreset
#/usr/share/ffmpeg/libvpx-720p50_60.ffpreset
#/usr/share/ffmpeg/libvpx-720p.ffpreset
with only 2 presets for libx264.
I installed ffmpeg from deb-multimedia. Is there a package which provides further preset files? There should be e.g. hq, max etc..

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 have used avidemux to cut a mp4 file, choosing just a part of it, and I have discovered it automatically adds "avidemux" to the beginning of the name of the file, plus the author of the file and that I cannot edit the file to erase it. Note that I talk about "right click - properties", and that the file, as seen from home folder dont include the "avidemux" prefix, but if, for instance, I run the file with VLC, "avidemux" will appear, and that is annoying. how to delete that annoying avidemux prefix?

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 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.

I'm copying an animated TV series from DVD to my computer. The DVDs are encoded at 29.970fps, which I find strange because animation usually uses 23.976fps. Anyway, what I have done is de-interlaced and re-encoded it to H.264. Now it is set to 59.970fps, which I think is higher than what I want. I'm seeking advice on whether I should leave it at that or change it to one of the lower frame rates. Another question: Do you think that I should be encoding to H.263 instead? This is just to have copies of the videos on my hard drive.
Note: I used Avidemux with the Yadif filter using the bob method to de-interlace the film. I think the bob method preserves the actual 60 fields and converts them into complete frames. I'm guessing that the temporal spatial check would halve the frames and give me the 29.970fps.

Handbrake simply will not encode. I've used it for a while now on 32 bit Ubuntu 9.10 and on 64 bit Windows 7 but since I've upgraded to 10.04 64 bit I can add a video as source and the encode button is grayed out. I cannot start encoding. The version of Handbrake I am using is 0.9.4.Does anyone have any idea how to remedy this issue? I am thinking of trying version 0.9.3 again.

rubyripper is designed to be the EAC for linux and in this thread here mc4man very kindly gave me the other box encode line for mp3HD slightly modified to give a 320kbps on the lossy aspect of the file
Code:
mp3hdEncoder -br 320000 -if "%i" -of "%o".mp3 - -Title "%t" -Artist "%a" -Album "%b" -Track "%n" -Year "%y" -Genre "%g"
ALSO IMPORTANT
MAke sure you have Lame installed on your synaptic the encoding relies on it for the lossy part and make it executable ALSO make sure you go into the terminal enter mp3hdEncoder and ACCEPT the agreement now i am seeking the same information for 3 other formats.
