Ubuntu Multimedia :: Video File Says It's Shorter Than It Is?
Aug 13, 2010
I have a video file I pulled off of a disc from a camcorder. The file is in .VOB. If I open the file in anything besides VLC, it says that it is 23 seconds long and will either play only the first 23 seconds or play the whole 15 minutes VERY QUICKLY.
So, if I want to put this file into a video editor, I can't do much with it because it either doesn't play at all, or only plays 23 seconds.
I'm guessing there is some metadata in the file that declares how long it is that VLC is just ignoring. How can I access and change that metadata to its actual length? I fired up a hex editor just to see if I could find the number 23 somewhere in the beginning of the file, but I couldn't..
Trying to sync a bunch of files to a 5.5-gen iPod with Banshee 1.6, on Lucid. I moved the files from my friend's computer to my Sansa View via UMS transfer; just dragged and dropped. The file lengths are correct on my player. My friend used Banshee to sync the same files, from the same computer, to his iPod. In Banshee and on his iPod, the files are all shorter. The files are supposed to be approximately 30 minutes each. In Totem on my friend's computer, and on my Sansa, the first file is 33:11. In Banshee and on his iPod, it's about 17:00. Some files have been cut down to two minutes long. This has happened across multiple albums in multiple folders. Clearly the problem is Banshee, since Totem recognizes the appropriate file length.
I want to be able to play a video file on my pda(Tungsten T5) but from memory the only video file i have seen playable on it was the asf file that is used when it starts up/reboots. I tried other file types in the past that were suggested in maybe a manual or forum or something but they never worked/played. I think it is because of the player installed and i tried installing another player but from memory that didn't install properly or just did not play anything. So if anyone knows of a way to convert files maybe using winff or mencoder i would love that info. I have been googling and have found nothing specific to what i am asking. I do not see anything in winff to convert to asf and cannot remember ever using mencoder.
After reading Jeff Atwood's recent blog post on solid state drives, I'm somewhat deterred in wanting to own one. I basically want to use solid state drives in my home network for the following purposes (all machines running 64bit Linux):
My main (pwn3r) desktop computer. This will be my main workstation for work, video encoding, etc. This will be running an Intel 980x 6-core processor, making it a beast. My hard disk configuration will be:
RAID-0: 2 Crucial 128GB Solid State drives for the main operating system(s), essentially providing 256GB of incredibly fast storage.
RAID-1: 2 WD 2TB Hard Disk drives for media and backup storage.
My network firewall computer. This will be running Untangle on my home network for content filtering and firewalling (if that's a word). It will be running an Intel Atom D525 dual core 1.8GHz processor. The hard disk configuration will consist of a single small 16-32GB solid state drive for the operating system and little, if anything, else.
My home HTTP/SFTP/file/backup server. This will be running a dual-core Intel i3 processor; it will be used for some video encoding, as a local DLNA server, a HTTP server for a few largely static files and perhaps some interactive scripts, a SSH server, possibly OpenVPN, and will be used to back up critical files over the network. It will be running RAID-X (where X > 0), meaning RAID-1 or RAID-5 or 6 for fast, redundant data storage, as well as a small SSD for the operating system.
I'm not exactly made of money, and I can't really count on buying four new SSDs every year or so. I can understand replacing them in computer number 1 once a year... maybe, but for the other computers which won't be utilizing the drive very much (ie: they're not power machines), it seems ridiculous to buy new drives this often.
My question is this: can I actually depend on solid state drives like I would on hard disk drives? Also, is this the best economic option? I'd like to save as much power and heat as I can, and solid state drives seem to be the best option at this point.
I have two video files taken with my phone, but unfortunately they are on their sides.
I was messing around with vlc, and found in the filters option menu, a setting to rotate the video 90 degrees, which is just what I was looking for.... BUT it won't let me save this (I guess you have to re-encode the whole file)
What is the easiest way to rotate video files (.3gp) and keep it in that state, without losing loads of quality?
I have rendered out less than two minutes of High Definition animation to Avi-Jpeg Format in Blender. Now, I have this 2 GB file. Going at this rate, it's going to take a whole DVD set to play a 15 min movie.
Surely, this file doesn't need 2 GB just for 1:45 min/sec, right? Even at high def? How do I reduce this file size down to like a manageable number, say, 20 miB?
I'm trying to extract the audio from an mp4 video file and convert it to mp3 using ffmpeg. The problem is that the resulting audio file is only 3m2s long, whereas the video file is 8m15s long. Anyone know why the audio file is being truncated? Am I doing something wrong? Apart from being truncated the mp3 file plays perfectly. Here's what ffmpeg has to say about the video file:
I was just wondering if someone could point me in the right direction of an easy to use soft package that can be use for basic video editing...and by basic I mean really basic - I have a video file (.ogg format) which is 11 mins long and I want to cut the last 3 minutes off.
I'm looking for a program of some kind that I can combine 4 (if not 2 minimum) streams of video into one file. The only program so far that I've found that does this is avisynth but I can't seem to make it work at all. Does it even work under ubuntu? I've tried numerous guides and how to's but nothing seems to be working.
Basically I just need something that will take a video file, from several different sources (cameras placed around a car) and be able to place them in a grid form into one file. Basically in a format like this, where each letter is a different video file: a b c d
I would like to get one software using which we can converto file format to another. Like .mkv to .mpg and .avi to mpg or .3gp to .avi . converting one to another.The other software I need is about ripping and editing mp3.From DVD video or VCD format, i would like to extract only audio mp3 files and i would like to cut some unwanted portion of those mp3 files.Which software do I need? I dont want to install Ubuntu studio
I need to know a command that is able find the hight and width of a video. I know in VLC you can go into the Codec details but I need something in the command line because I have hundreds of files that I need to organize. I could not find any VLC command that does what I want to do.
I have lots of 720p MKV files which play fine on VLC and/or mplayer. These are the two players I know. Whenever I try to play a 1080p file, the video is sluggish and quickly desynchronizes from the audio (mplayer) or the sound is choppy (vlc). This is because one CPU cannot decode a 1080p x264 video. Not powerful enough. Now, I have a Q6600, with 4 cores. Options in mplayer and VLC to use more than one decoding thread don't seem to do anything at this date, as one core is only user (reported by TOP).
every time I reboot and play a video file the colours are messed up. I need to manually increase then decrease the hue or saturation to get the picture to normal in smplayer. The colours aren't competely inversed as in the common bug with the totem sliders, they're just far too red and bright.Smplayer is the latest from PPA. I've checked the totem settings and everything is OK. It only takes two key presses to resolve but it's a pain, to be honest, so if anyone knows what causes this and how to fix it permanently I'd be much obliged.
is there a way to pipe a video feed from virtual box to vlc and save it as a file? cause if i could then i could save streaming videos from places like hulu and netflix or save bluray movies to a avi file for latter use.
Can I ask for some advice in converting a video (from my phone) which is a 3gp file into something more universal. I use audokonverter for audio files and this gives me a menu right-click option to convert a song from (say) wav to mp3. Is there an equivalent for videos? I am using opensuse 11.4 64 bit and have mplayer, xine and vlc installed plus the necessary codecs. Or is it simpler to use ffmpeg in a c/l environment
I'm having trouble playing back videos from a DLNA device in Ubuntu 11.04, and I'm not sure where the problem lies.
Using the software manager I've installed the extra plugins package for Totem, and enabled the Coherence DLNA/UPNP plugin. I can see the device (Humax Freeview HD recorder) in the MediaServers list, and can browse through the programmes I've recorded on it. However, trying to play any of the has no effect, the main part of the window still shows the "clapperboard" graphic.
I noticed that the "recent files" filenames that were appearing on the Movie menu didn't match the ones that were listed in the sidebar - they're of the form e.g. 313.TS rather than the original descriptive name with a .ts extension. Running Totem from a shell prompt, I can see the following console output: request to play: Man on Earth_20110622_0508.ts 013311314 http://192.168.254.1:9000/web/media/313.TS I tried entering that URL into Firefox, and it started downloading okay; according to the LiveHTTPHeaders addon the response headers are
Why can't Totem play the file? Some other codec needed for video/ts files that I've not got installed? (it hasn't prompted me to install any extra packages) Does it just not like the fact the file extension is upper case? Or something else entirely?
On a separate machine, also running Ubuntu 11.04, I installed the VideoLan client; VLC can browse to the files and play them without any problem. So why can't Totem?
I have problem with VLC player. The problem, from the image below, appears whenever I open video file. I click Ok, and a everything is ok, until I jump to another time sequence, when sound and subtitles disappear.
I want to watch a certain video on [url]...., but I get an error message instead. Some videos can be played, so I'm thinking it's a form of restriction, but I can't be sure.I tried using a few proxies, but on some the error message persists and on others the video doesn't load. I'm running Ubuntu 9.10 and Firefox 3.5.8.
I have two seperated video clips, that captured same event from two cameras. i would like to create one clip, that will show one on the left side, the second on the right side, and play together.
When I play large HD videos in mplayer, the video and sound frequently get out of sync, and the video plays a little strangely (occasionally speeding up and occasionally slowing down).
I think it's because mplayer is only running on a single core. As I've got a quad-core processor, it seems inefficient. I've seen that there is theoretically a way to get mplayer to work with multicore setups, but it requires compiling with different options. That'd take me a little while to work through.
Ideally there would be a pre-compiled version in the software centre, or a player which has support built in (again, ideally in the software centre). Is there such a thing available?
I have a video file in which the audio runs faster than the video, so they quickly go out of sync. The way to fix it would be to separate the audio and video streams, speed up the video (the audio is FINE, it's the video that's wrong), and then recombining them. What is the easiest way for doing that?
