Ubuntu Multimedia :: Can't Encode Files With Mpeg-4?
Nov 28, 2010
This is my first post in this forum. After trying out every video compositing program I found for Linux, I am about to settle with KDEnlive. It looks like the best allrounder professional program in this section to me.
I only got one problem. I cant encode files with mpeg-4. All options here are grayed out and if I hover over one of the options for a moment it's going to tell me:
"Unsupported audio codec: libmp3lame" Whats funny is that it worked a time before i reinstalled my system. I also checked and I got libmp3lame installed. So why has KDEnlive problems to access this library?
I have been searching the forums with limited success on how to convert MTS files to MPEG. I have been able to open the MTS file with OpenShot and KdenLive but they aren't really for converting files or at least I haven't figured out how to do it. Is there a simple GUI tool to convert these MTS files quickly and easily?
I have some videos made with a digital camera in mjpeg format and I want to convert so something else, into xvid, mkv or I dont know, just to made them smaller without quality lose. So is there something GUI for this, or I need to start reading the mencoder man page?
I am looking for a simple tool that would allow me to stitch together short mpeg files or to cut out unwanted sequences of files, without having to use a heavy video editing programme like OpenShot.
If it can do the same for audio files (mp3) and possibly convert between formats, even better !
There's so little documentation for GLC that it's nearly impossible to get it working. I just tried encoding a file I made using the script provided, and got this output:
Code: joseph@joseph:~/Desktop$ sh encode.sh lugaru-17880-0.glc [: 103: lugaru-17880-0.glc: unexpected operator
After several google searches and forum searches, installing restricted repos, encoders, codecs, ffmpec still REFUSES to encode H.264. Here the output of an FLV to be converted:
I recently installed Ubuntu 10.10 after using 10.04. While using 10.04 I used ffmpeg quite a bit and just a few days ago I was using ffmpeg to encode video with the h263p codec.Anyway, for some reason ffmpeg no longer seems to want to decode h263p anymore. If I type "ffmpeg -codecs" to get a codec list, I get" EV h263p H.263+ / H.263-1998 / H.263 version 2"When it used to be "DEV" for decode / encode video. But now just " EV"Even on the ffmpeg website here http://ffmpeg.org/general.html#SEC3 it says ffmpeg should still be able to decode h263p. Yet, it can't!I've tried installing all sorts of codec libraries and I even followed a guide to download and compile ffmpeg myself. Nothing seems to change.
I can't for the life of me find the option to encode my video in H264 in Pitivi. There's just about every other codec imaginable in the list. I'm running Ubuntu 11.04 32-bit and everything is up to date.
I used K3B to rip some of my DVDs (using the Xvid codec) onto my laptop to take away on holiday with me. This worked fine for 2 of the DVDs but the 3rd one ended up with the audio out of sync with the video. Fortunately VLC comes to the rescue with the ability to offset the video and audio tracks.Is there a way to re-encode the ripped files to permanently fix the offset.
I have a lot of old video footage around that, I am ashamed to say, I encoded with heavily proprietary codecs like DivX and such during the dark ages (aka. the Windows Times).
Now, I would like to redeem myself from the mistakes of my past by re-encoding everything into open formats. Since those videos are often not of the best quality (poor camera, poor codecs, poor knowledge), I do not want to loose more quality in the process.
So, to avoid any more mistakes in the future, I would be glad if someone could answer me some of the following questions: 1. Is it even possible to re-encode those movies into something like x264/vp8/theora without loosing any more quality? 2. What tools should I use for that? Command line is actually preferred. 3. What would be the most desirable format to have? I'm thinking about x264 in Martroska with ogg Auto. Is there anything better suited?
I have been having a problem with K9 Copy whenever I try to convert a DVD to MPEG files using the method without encoding, but for some reason lately it seems to be splitting each episode into about 6 or 7 pieces instead of just one. I never usually have a problem with this, but for some reason it seems to be doing this whenever I try to rip something. On a side note, I am running on Obuntu 9.10 and have K9Copy version 2.3.0 installed. I have tried installing several other versions, but it does the same thing with each.

I have just captured some screen-shots with GTK-RecordMyDesktop, but now I can't use them. The videos plays right in vlc and totem, but crashs Pitivi and turn into pink splotches in kdenlive. When I convert them using ffmpeg, the video turns into blue and pink splotches. Here is how I'm converting it:Code:ffmpeg -i out.ogv out2.mpgConverting it with vlc crashes the program.I never had problems like this before. I have used recordmydesktop and ffmpeg many times, but on a 32bit computer. I have a 64 pc now, running ubuntu 10.04 x64.
I need to convert an mpeg into a series of still images but I cant find any software on linux to do this unless you know of any software that can convert video into vector style graphics
downloaded dvdrip from synaptic, got all dependencies, got the css library... When I click the button to collect the table of contents (DVD's info from the DVD, it seems), it just flat out fails. I get a warning dialog with this message: "Job 'Read TOC (lsdvd)' failed with error message: Error reading table of contents. Please check your DVD device settings in the Preferences and don't forget to put a DVD in the drive. The log looks like this:
Looking for efficient program for Ubuntu like DVD Flick for Windows to convert one or several mpeg videos to DVD without the necessity to make a menu screen with choice buttons. I want the videos to auto-load and run continuously. I have tried all the programs in the U. Software Center and none have this option. (Or I have not been able to discover it).
I have an MPEG video file of 1.2 GB. I want to chop it into three (unequal length) pieces so that each piece can play well as a standalone video clip in most media players.I tried using trusty old Avidemux, but I'm getting problems at the start of vid clip #2 and #3, where the colours go very odd indeed before righting themselves after a few seconds.
The settings I used were:
Code:
Video: MPEG-4 ASP (avcodec) Configure: Constant Quantiser - 4 (all other settings at default) No filters applied. Audio: MP3 (lame)
[code]...
The settings above are those I use most often and I usually manage to get reasonably decent output. But this is, I think, the first time my input has been an MPEG file.
I am running 10.10 64-bit and am trying to get an option in WinFF to convert an MPEG file to an iPod compatible video. All of the HOT_TO guides I could find involve installing the FFmpeg libraries, which I have done as well as I could have.The problem is that within WinFF, I don't see anything different in the "Convert To ..." drop-down. The Wiki I am reading tells me to select iPod, but this isn't available.What do I need to do to get this to be selectable?
i try to split mpeg file using ffmpeg. The splitting itself works OK, but the quality is lower. What should I do in order to keep the same video quality?
