Ubuntu Multimedia :: Mass Encoding Into X264?
Jan 3, 2010
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 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?

What I am trying to do is to convert a mass of files from standard Windows text encoding to UNIX encoding(462 .txt files). After a bit of searching, I found this bit of code, changed the necessary parts, put in "Sleep" so I could see the output and ran it:
Code: #!/bin/bash
FROM=iso-8859-1
TO=UTF-8
[code]...

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:
Linking CXX static library ../../lib/libhighgui_pch_dephelp.a

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'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've got a bunch of wmv files that I'd like to re-encode to avi - about 50 of them. Is there a straightforward GUI application that does the same thing as Sound Converter does with audio files? As in, add a folder full of files, select the output format and output filename/folder, click "convert", and come back a few hours later.
Yes I know I can convert video files with mencoder and ffmpeg, but doing it file by file at the command line means I can't leave it running overnight or something.
I found something called Arista but the only output options are designed for specific hardware, ie. iPods and PSPs. I just want to convert the wmv's to avi's, not mess around with resolution etc. Also, with Arista you still need to add the files one at a time.

I am so completely frustrated with this and can't seem to find any solid answers. I have a Google Nexus One phone. I want to also use it as a portable music player. I can find no player for Linux that can do ALL of the following:
- copy music
- transcode when necessary
- transfer cover art in appropriate format
- transfer playlists (music files AND .m3u playlist files)
Banshee is the closest, but it is so painfully slow, has many problems with tags and also doesn't transfer playlist files. Banshee advertises support "out of the box" for this device. I've tried overriding with an .is_audio_player file, but it is ignored. Rhythmbox will transfer song files and transcode as necessary, but no artwork, no playlists. Exaile doesn't recognize this device for some reason.

I share my music between ubuntu and windows 7 (nothing fancy just copy, paste, external hard drive). and have learnt that my music collection doesn't show up right in windows media player because WMP can't read version 2.4 right. most of my collection is saved in 2.4. I used mp3tag on windows for converting my whole collection but wiped the computer recently and had to start over. This time i would like to just convert my whole collection on my ubuntu pc through the terminal. I tried using EyeD3 but it didn't seem to work for me. But perhaps i typed the command wrong. Could someone show me either a proper command for converting my mp3 collection to v2.3 OR recommend another ubuntu program/commandline that can handle 7,500 songs and convert them to ID3v2 v2.3.

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.

I have a 1TB external HDD which I use to store my music library of roughly 40 gigs. Therefore I would normally import music directly from it to my Rhythmbox library while keeping everything stored on the removable drive. In recent versions of Rhythmbox this is no longer needed as the application integrates my external HDD into the side pane and lists the music automatically. This is great although when closing Rhythmbox and reopening it, the drive has to be scanned all over again. This is a huge pain when it has to scan through 40+ gigs of music.
Therefore I would like this feature disabled and removed from my side pane. It is not needed and causes quite a large annoyance. Either I want it removed or the ability to keep the index of music from the drive in Rhyrhmbox at all times. Achieving this would be fantastic and would switch me back to Rhythmbox. recently I have been using Exaile which I love but rhythmbox not working bugs me.

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.

I need to enable my new E2120 samsung phone as a mass storage device. but I think I need a USB driver. Had a good look round the forums but can't seem to find any posts. Its quite a new phone but hopefully the solution is already about. When I plug it into the USB the phones screen has a hashed out 'mass storage' option.

I'm trying to encode a video using only one image during a complete audio file, but a can't find the way to do it. What I need to do is to extend the duration of the frame up to the duration of the audio file. How do I do that with mencoder?

Since I use openbox with some packages from Xfce4 (mainly for convenience) I get most stuff "for free" as it were when using openbox, but I can't figure out how to mount android devices in a simple way. I can either do it manually, or install some other file manager that has this capability. This leads me to my question, I've noticed that if I install Nautilus, which automatically mounts android devices OotB, I get this functionality in Thunar as well. This leads me to believe that there is clearly a dependency package of some kind installed when running apt-get install nautilus that enables it, It'd be great to get this functionality in Thunar without having all the nautilus packages just littering about for no good reason. the required package is gvfs-backends, which I should have realized when I was unable to browse smb:// addresses. You forget a lot when you only make a fresh install once every 2 years or so.

I am using 11.2, KDE 4.3.5 with Grip and Flac to rip and encode CDs. Two questions:- Have read flac -help and do not understand the -o option which is used in a few example threads. The man page suggests that -o should be used with subsequent parameters such as --output_name=FILENAME for example. In the example posts this general option is used on its own. What for?
The installation when first used, already had a string of options including --best on the command line. I cannot find any documentation for this. I assume it is a preset in the same way as for example --preset extreme in lame.

It is well known that mencoder can be used to encode video to be burned on DVD with a tool like dvdauthor. The whole procedure is described here:
7.8. Using MEncoder to create VCD/SVCD/DVD-compliant files
Sound for a DVD is normally encoded with AC3. I encountered some cases where the encoded sound was badly distorted. As it seems, the default for the input changed to float at some point. The fix for this is to use:
Code:
acodec=ac3_fixed
instead of "acodec=ac3".

I am trying to perform a 2-pass encoding of a video from .mov to .webm, but it looks like that the 2-pass encoding is much worse than doing a single pass encoding. Here are the two commands I use:
Code: Select allavconv -y -i input.mov -r:v 25/1 -c:v libvpx -minrate 400k -maxrate 600k -b:v 400k -s 640x360 -force_fps -b:a 80k -pass 1 output.webm
avconv -y -i input.mov -r:v 25/1 -c:v libvpx -minrate 400k -maxrate 600k -b:v 400k -s 640x360 -force_fps -b:a 80k -pass 2 output.webm

I am unable to rip from CD to .mp3 using pretty much any tool. Dolphin / Konqueror auidiocd:// KIO slave shows the mp3 folder, but when you move the tracks you get: Could not read some_song.mp3: encoding failed WARNING: libsndfile may ignore -r and perform fseek's on the input. Compile without libsndfile if this is a problem. I'm running 11.3 (KDE 4.4.4) with K3B 2 from Packman (with the k3b 2 codec package) and K3B fails as does the KIO slave method above. Lame version is: lame-3.98.4-2.pm.4.1.x86_64 Restricted multimedia formats packages are installed from Restricted formats/11.3 - openSUSE Community Wiki Alsa works great otherwise, I have no sound issue, etc. - just can't rip anything to mp3 Seems like I'm not the only one who has had this problem, there are a few posts here on the Suse Forum, and others elsewhere, but the resolution seems to be nebulous at best. Sometimes lame 3.98 from packman works for some guys, other times not, etc. Unable to rip an audio cd into mp3's using 11.2 - opensuse.opensuse.org - ArchiveOrange
