Ubuntu Multimedia :: Tool To Compress/splice Videos?
Jan 9, 2010
I have a few '.flv's now and most are small enough to upload to my Joomla web site and play with AllVideos (extension) but a few are over the 10M limit, I have one that is actually 50M! Is there something I can use to either splice the videos (make 2 or 3 out of one, upload seperately) or to compress down to 10M- w/o wrecking the quality?
I'm using vmsplice & splice to send memory buffers through a TCP socket. I have two issues using these methods:
1) According to the documentation, when using vmsplice with the flag SPLICE_F_GIFT, you cannot modify the buffer you've "given" the kernel. Currently, each time I want to send a buffer, I have to allocate a page-aligned buffer (fill it with data) and send it using vmsplice- splice. When can I deallocate this buffer? Is it possible to modify this buffer after the buffer is sent through the socket?
2) The buffer should be page-aligned both in memory and in length, but most of the time the sent messages (to the TCP socket) - are smaller than a page size - is it possible to "clear" the pipe from the remaining buffer?
i want to be able to convert videos into mp4 videos of resolution 320*240 and frame rate 25ps so that i will be able to play them in my phone..any video converter that can do this job for me?
I can get all the utube videos other website videos , but no BBC videos using U 9.10 and Opera 10.10. They work with FF or Using Opera in Fedora it works fine. I have all the usual Gstreamers, restricted extras/flash player etc. I read just about every post I can but see nothing I do not already have.
I cannot get AVI videos to play with the Totem movie player that comes bundled with Ubuntu 8.04 on the Dell Mini 9. I keep getting: "Could not determine type of stream." Randomly, one or two of the dozen or so videos on my SD card will work, but most will not. This is very frustrating because all the videos I download are always in AVI format.
I tried used the synaptic package manager find an alternative player and tried MPlayer, but that didn't do anything. I'd just get a blank screen on everything. Using the tutorial in this forum, I got GNOME Mplayer, which also didn't work, but even a video that worked with Totem would only play audio with GNOME Mplayer.
I looked in the repository for video codec updates but didn't see any. What do I do? Is there like a Winamp for Linux? This is a total bummer. I just want to play AVI files that are so commonly used for video.
I'm trying to find a program where I can edit some hd mkv files. I want to cut pieces of them out and put them together. I was using avidemux but when I went to save it again it said I needed the start point to be a keyframe. It allowed me to save it as an avi, but the color was distorted. I am fine with using avidemux if I can get around this keyframe problem.
I have an issue with my Ubuntu both 9.10 nad 10.04.I had the video worked perfectly untill yesterday but now i can see the video hear the noise (cars, music) but no voice of human.
I had system problems and I decided to do a fresh install and I could only save my home folder and be sure that my system worked. Ever since my new videos never had thumbnails. Is there any way to make sure they do have thumbnails for easy browsing.
I have used ubuntu for a long time but always using either a live CD or my Flash stick.
On past Thursday i decided to install ubuntu on my laptop and i did it . It is light and healthy (ha ha). Any way, I would like to play AVI, MKV, RMVB, and MP4 videos but i couldn't. I tried a lot of debian packages and drives (i.e. files with .deb extension) but no result except installing RealPlay that i am using it to play mp3 files only.
can you give me some packages to play those files. (I can't connect my laptop to Internet for the time being). In addition, I have Huawei E1750 USB Modem but the system does not recogize it. Is there any way to play those videos and surf the net using the modem in UBUNTU 10.04 LTS.
I've been trying to convert flv videos to MP4 so that I can load them onto my iPod Classic 160 G (video).
So far no program has successfully converted an flv file to a usable mp4.I've tried Avidemux (both gtk and qt), Kdenlive, WinFF, Mobile Media Converter, DownloadHelper (FireFox addon) Tragtor and of course the King of them all- FFMPEG. Not one of the previously mentioned programs has successfully and consistently converted an FLV to mp4 for my ipod.
It could be that I'm doing something wrong with FFMPEG or don't have the correct codecs (whatever the heck they are?!) installed or that I voted for McGovern in '68. The "help" from FFMPEG both IRC and their obnoxious email list is beyond deplorable.
Anyway, I need to know a reliable and consistent way to turn flv or any other videos into an MP4 format that will run on my iPod. The program must reside on my machine and not some online converter service. If I have to use FFMPEG (which I understand most programs use as their core) I need to know how to do it....and for God's sake don't tell me to read the online documentation at FFMPEG..
My Dad who I have just gotten on to Ubuntu is wanting to burn some some avi videos onto a DVD, but wants them in a DVD format though so that he can play them on any type of dvd player. I got him to install k3b and try that but as I've never had to do this I'm not sure my self how to do it so this leads me to ask;
I have some 10hrs videos with around 6GB in size. Unfortunately avidemux2_cli runs into problems copying certain parts of it into an output file (frames get blur).
So I tried ffmpeg, but even if I use the sameq switch (same quality as source video), the output video is not a 1:1 copy of the source video. In fact the output video is encoded again (and sound is not as in the source video) and that takes ages against a copy activity by avidemux. Is there any other cli program for simply copying parts out of videos?
I've got an eeepc 1101ha and have installed the latest ubuntu, 10.10, but i can't watch any videos! Besides the original player, i have installed and tried to watch videos in VLC, SMPlayer and GNOME MPlayer but it has always some kind of error. In VLC I can hear the sound. On all others the file simply doesn't work.
I'm able to get HDMI audio/video perfectly when I'm playing a dvd on mythbuntu. However, If I try to play the ripped version or any other video that is on the hard drive, I get no Audio?
I've checked alsamixer to make sure the device isn't muted.
If I use vlc media player I don't have any audio either. Is there a way to enable hdmi audio as default?
If I try playing ..... or other streaming video I have no sound. It used to work and then my dumbA$$ tinkered with it and now I have restored Flash, which was working flawlessly, don't know where my head was at but it was dark and smelly.
EDIT: I have Ubuntu 9.10 and my sound card is an nVidia Corporation MCP61 High Definition Audio (rev a2). I tried to follow along with the instructions in the sticky regarding the

Comprehensive Sound Problem Solutions Guide
but when it gave me the instruction to select my sound card manufacturer from the drop down menu, I never found it.
FWIW, my speaker are on and they play music, system sounds etc, just no sound for streaming video. Pandora works fine etc. Also, this is isolated to Firefox, as it works fine in Opera.
I am having a little problem with my flash player, the video plays fine but I can't get any sound. The sound card works properly with any other application, such as Amarok, but not with flash videos and my hardware is mostly Intel witch is linux-friendly from what I know, so I guess that it isn't a driver problem. Therefore, I switched from windows to linux only a couple days ago, so it may be a newbie issue as well.
I'm using Kubuntu 10.04 64-bit with HDA Intel audio chip set with flash player 10.0.45.2. If anyone have a solution/explanation,
I am trying to combine two videos into one file, so that I can have them playing side by side and in sync.Basically they are two angles of the same thing, and I want to be able to demonstrate both at once. The files are completely different formats right now (MPEG-2 and h.264), but I could convert them. Is there any way to do this, or a way I could have them both play in sync even if I can't combine them?
I've seen posts with similar titles on these forums, but I know nothing about the plethora of codes out there and all those thread seem to be way over my head. I've installed ffmpeg (an unrestricted version) but I can't convert m4a audio files to mp3 audio files. I installed a package called 'libavcodec52' from synaptic because it came up in the search results for 'm4a' and its description said something about m4a and ffmpeg but still no luck..
I have both a 64bit 10.04 install with firefox 3.6.6 and flash player 64bit version 10 and a 32bit 10.04 netbook edition with firefox 3.6.6 and flash player 10.1. They both are missing the overlay controls.Here's an example link:The pbs kids site has the "BIG" button which allows me to go fullscreen, but then I just get audio on the 64bit machine. I haven't tested that on the netbook version yet.
Video files (eg. .mpg, .avi, .flv) work fine on my Dell Inspiron 6400 laptop until I plug a second monitor (or data projector) in. Once the second screen is plugged in the sound plays but the videos are blacked out. It was a bit embarrassing when I went to do a presentation today. Running Ubuntu 10.04.
I have a bunch of videos that I would like to adjust the volume to be the same on all of them. I have searched and all i can find is how to normalize the volume with in the video. I have tried this and it works great on movies where the action is louder that the talking. My problem is on video is a lot louder than another so im constantly changing the volume when a new video starts.
I'm not sure if this is a bug for firefox, kde, kubuntu, or adobe flash playerbut every time I go on an online video site like ..... I see a lot oftearing. And when I say a lot of tearing I mean tearing when their is barelyany motion at all. I know that my video driver isn't the problem because when Iswitch to fullscreen any tearing that their might be is barely noticeable. AlsoI haven't noticed the problem while in gnome. Reproducible:AlwaysSteps to Reproduce:1. Watch an online video while in kde2.3.Actual Results: Tearing while watching videos regardless of the amount of motion
