I recorded a TV show on my pc using mythbuntu software (ubuntu version of mythtv). It cut out all the commercials and then transcoded it to a nice 40 min nuv file that I put onto a usb thumb drive. Now it's portable and vlc can play the file...on a pc. I want to burn it onto a DVD so I can put it in any NTSC DVD player. Also, the file was recorded at 480x480 and I want to change the size to widescreen (16:9). Additionally, the top of the screen recorded a thin horizontal line of junk that needs to be deleted.
Now, I've googled around and found this line in ffmpeg that should work:
The new 16:9 video size is great, the annoying horizontal line got cropped, and I got a nice mpg file...but the audio is now out of sync. I tried ffmpeg with fewer options and the audio still got out of sync.
So, I'm thinking I should try different software. Maybe mencoder. How could I put the above ffmpeg options into mencoder?
I'm trying to convert my screencast to an .avi file, but when I open it... the commentary track is waaay out of sync. No matter which codec I use, it will not stop dropping frames!
The version of mencoder I currently have installed segfaults (immediately) when you ask it to convert x264-encoded MKVs to another format. One sample command-line would be:
Code: mencoder -nosound -ovc libdv Puella_Magi_Madoka_Magica_720p_GG_-_06.mkv -o a.avi This produces the following output: Code: MEncoder 20110702-4.5.2 (C) 2000-2011 MPlayer Team success: format: 0 data: 0x0 - 0x1c43987e libavformat file format detected.
[Code]...
Incidentally, I'm wondering if the version of FFMpeg that the MPlayer configure script downloads might be at fault. The slightly outdated FFMpeg I installed from SBo (6.1) does not crash when converting the same file. And no, I can't use either Alien Bob's Mplayer build or the MPlayer binaries included with Slackware. Neither is built against either libdv or x264. I need libdv as an output codec.
I am working in a script I have, to capture video with sound from my capture board, wich is a clone of the pico2000. This script was working in Ubuntu 9.10 untill I reformated my machine and instaled the Ubuntu 10.10, 64 bits. The machine is an AMD Athlon II, 2.6GHz with 3 GBytes of Ram. The former script was:
My 1st and only grandson turned 1 year old and we have taken about 1 million pics of him. I wanted to make a video from pictures taken in the past year. The first one is an ultra sound picture. The last one was taken this last Saturday. I have 153 12 MPixel pictures in a folder. They are named C001.jpg - C153.jpg (I can rename them if needed).
I had noticed mencoder or ffmpeg can create movies from jpegs. But, I didn't think about the frames per second. Would I need to make like 20 copies of each picture and then make it like 10 FPS? or something like that? Optimally, I would like to have a video where each picture lasts for 8-10 seconds or so and I would be able to add a song as audio. (I think I know how to use mencoder to add the audio).
What is a good app to convert videos in Ubuntu? I usually watch documentaries, movies etc in my mobile phone and need an app to convert AVIs etc with a low file size and about 320x240 resolution. Used WinFF but it doesn't seem good enough
Its no secret that flash video performance is sub-par in Ubuntu. I have a Zotac Mag HD ND01 that I have connected to my 40" LCD tv and have a minimal Ubuntu 9.10 installed running openbox and firefox/boxee/xbmc
My primary use for running a web browser is so I could watch live streaming hockey games in HD. However, thanks to Flash's performance (and yes, i've tried the latest versions, even the 091510 version in labs) in full screen mode, watching hockey is not possible because its way too choppy.
Now, on my desktop computer in my office, I can watch the same stream without issue. So, my question is, is there any way to take this live stream (which is using Flowplayer), and re-encode it on-the-fly so I can stream it to my htpc in a format it likes (such as MKV i guess, it can play 720p/1080p mkv files without issue)?
My desktop is a Core i7 920 overclocked to 4.2Ghz with 6GB DDR3 ram, so I would hope its powerful enough for the cause. Also, the desktop is running Windows 7 64bit and Ubuntu 10.04 64bit on a dual boot, so a method in either is fine.
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 need a way to batch convert 720p video files from avc1 to xvid in Ubuntu 10.04. I'm not terribly concerned about file size, but I do wish to retain the picture quality as much as possible. I believe the audio is encoded as aac, which is fine for my purposes.
What would be the best and easiest way to do this? I've tried using Handbrake. During my first attempt, I had it using ffmpeg to convert to MPEG-4, but that just gave me a super-low quality video at twice the file size. Trying h.264 now, so we'll see how that works out. But just in case it doesn't pan out so well, what other ways do you recommend?
I was thinking I'd write a bash script to reencode the files one by one, but the problem is that I have very little knowledge about codecs and containers and whatnot - so I wouldn't know what parameters I would pass ffmpeg/mencoder.
I have a collection of music videos of various ages, and want to consolidate the codecs into mp4 files with the following criteria:
1) Retain the same directory structure and same name, hopefully with something like "/music/Videos (Encoded)/" and "/music/Videos (Failed Encoding)/" (Note: Using UTF-8 filenames)
2) Prefer to do this all in one batch; terminal commands/ bash script = awesome
3) Keep the highest quality video without having to encode everything the same (some widescreen, some hd, some with super low resolution)
4) Retain the audio stream untouched (plus, some help on what command to do to convert it to a good format) and, hopefully, to encode with settings that allow for universal apple playback (Handbrake as a great preset for this)
I have movies downloaded onto my Linux based system and want to convert them so I can burn them to ddvd so I can watch from my couch. I have found a couple for windows but not Linux. By the way I running Mint 8 -X64.
I'm just wondering if anyone knows of a rmvb video converter that works with ubuntu. There is a windows rmvb converter, but when I try to use it through wine it either crashes while converting or just doesn't work period.
i am using ubuntu 8.04.I wanted to clip from a movie so I ran
Code: mencoder -ss 2453 -endpos 34 InpuTFile -acodec copy -vcodec copy -o Output I changed the ss value still it cut from same frame of the video.It seems mencoder works faster than ffmpeg but jumps to keyframe hence cannot jump to accurately specified second.
I have found that if I change the FPS of a video, the audio is out of sync.
Is there a way in mencoder to have it correct this, and maintain the correct sync?
I don't think it is just a matter of audio/video delay. I have tried many times to correct this via that method, and it doesn't come close. Although, if I encode the video to another format, but with the original fps, the audio is sync'd.
A recent update to ffmpeg, in which I've learned was an upgrade to the restricted ffmpeg as opposed to the unrestricted default one that is in the official repos, has now made it unable for me to use mplayer or Devede. Reading up about this, especially from here: [URL].. I have learned it's a frequent problem when installing the restricted ffmpeg. Basically what Devede says at startup is:
Code: Cant's find the following programs: mplayer mencoder
Devede needs them to work. If you want to use Devede, you must install all of them. Using the terminal to open mplayer (or mencoder), I get this error: mplayer: relocation error: mplayer: symbol codec_wav_tags, version LIBAVFORMAT_52 not defined in file libavformat.so.52 with link time reference From my research, seems as though the problem lies in libavformat52 not being installed (or removed) and libavformat-extra-52 is installed, which is the same thing, but because it's the restricted version, it is called something different. Anybody know if that is correct?
Also, checking up, libavformat-unstripped-52 isn't installed but available, so should I install that to replace the missing libavformat52, as when I sudo aptitude install libavformat52, it says it conflicts with libavformat-extra-52?
I installed libavformat-unstripped-52, which didn't conflict with the already installed libavformat-extra-52, just to see if it would basically just replace the missing libavformat52, which conflicted with libavformat-extra-52 and couldn't be installed safely, but after I did, nothing changed. I still get the same error with opening Devede and mplayer (or mencoder) in the terminal.
I have an 8Gb mkv file, which I tried to encode to avi using mencoder, it took more than 6hrs and when completed, the quality of the avi was pretty poor.Is there a way to increase the quality or is there a program that can encode mkv files? The mkv will not play on my system without stuttering badly.
I was just wondering if it is possible to output an encoding file to http, mms, udp etc... (eg. http://127.0.0.1).I found a way to input these streams and encode them I just cant find a command to output to these.
I edited some mpeg videos using Mencoder to crop unwanted footage from the beginning and the end. It worked, but now the file does not have a "visual" icon, i.e. a still from the video. The properties of the new file also reveal that it thinks it's an audio file! The file still plays (as a video) okay though.A typical command I used to extract just the first 14 seconds of the video was:
mencoder "e03.mpg" -o ee03a.mpg -ss 0:0:0 -endpos 0:0:14 -oac copy -ovc copyI did try to make up a new icon by making a snapshot of the movie playing, then using the image to replace the icon in the properties window. (I am using Nautilus file manager in Ubuntu). The icon it now gives me looks like a small sheet of paper with one end curled up.I can appreciate that editing the video length might have "lost" the icon information, but is there any way I can put it back again
I'm trying to convert a video in .ogm format to .avi format so I can stream it to my PS3 via uShare. I'm using Mencoder and the following command to do it (to transcode the audio from vorbis to mp3 and the video from mpeg4 to xvid):
Code: mencoder input.ogm -oac mp3lame -ovc xvid -xvidencopts pass=1 -o output.avi.The only problem is, the video contains 2 audio streams - one Japanese and one English. Needless to say, I need the English one. The above command only seems to transcode the Japanese audio though!Here's what ffmpeg has to say about the input file:
what I can do to specify the correct audio stream to encode? Also, how can I keep the bitrate the same as the output.avi seems to default to 96kbps?I'm not sure which audio stream is which but a little trial and error will sort that out in no time.
