Debian Multimedia :: Up-to-date Binaries Of Mplayer, Mencoder And Ffmpeg
Mar 18, 2010I'm wondering if anyone distributes mplayer, mencoder, and ffmpeg, up-to-date builds of each and their associated dependencies (x264, faac, xvid, etc).I had to compile all that stuff myself and fought with it, and finally got it working.
If no one distributes latest builds, then I was thinking of going further with what I've done to help others: virtualbox lenny and automated compiles of all packages and putting up the builds, with latest revisions of mplayer and ffmpeg from their source code repos. Using LD_LIBRARY_PATH to isolate the build so any modern linux can run the produced binaries, with only glibc as a dependency.
Ubuntu Multimedia :: Video Capture Using Mencoder?

Ubuntu Multimedia :: Create Video From JPEGs - Use Mencoder To Add The Audio?
Jan 18, 2010My 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).

Ubuntu Multimedia :: Getting Video Info With Ffmpeg / Mplayer?
Feb 19, 2010I am trying to get a listing of video information using ffmpeg or mplayer. I have found a way BUT it is only returning 1 piece of info..
Here is what I'm doing in PHP:
print exec("/usr/local/bin/mplayer -identify file.flv -ao null -vo null -frames 0 2>/dev/null | grep ^ID_");
But this will not provide an entire listing, it will only print out 1 thing such as:
ID_AUDIO_CODEC=mp3
I can specify what exactly I want to know something like:
print exec("/usr/local/bin/mplayer -identify file.flv -ao null -vo null -frames 0 2>/dev/null | grep ^ID_VIDEO_WIDTH");
but I want to just have all the info available at once instead of having to loop through like 20 times..

Ubuntu Multimedia :: Trim Video In FFmpeg Is Not Accurate?
Aug 13, 2011I tried to trim a video in FFmpeg using this command:
Code:
ffmpeg -ss 00:20:48.500 -t 00:01:00 -i INPUT.mp4 -acodec copy -vcodec copy OUTPUT.mp4
But FFmpeg is not accurate and it started the video from a nearby point instead (from 00:24:46~). I tried to add 2 seconds to my starting point and it took another frame (not what I wanted).
The video source is H264 video with AAC audio.
Ubuntu Multimedia :: Lossless Padding Of H264 Video With Ffmpeg?
Mar 11, 2011I have some videos in an mkv container that are 1920 pixels wide, but less than 1080 pixels high. This causes problems when playing the videos on a PS3 (after converting to an AVCHD system), because the PS3 won't centre the video, leaving a very large black bar at the bottom but none at the top. Is there a way to use mencoder or ffmpeg to losslessly add padding to the top and bottom to make the video 1920x1080?
If I use
Code:
ffmpeg -i video.mkv -acodec copy -vcodec copy -scodec copy -padtop 132 -padbottom 132 out.mkv
then ffmpeg won't do the padding, and the resulting file is basically exactly the same. If I use
Code:
ffmpeg -i video.mkv -acodec copy -vpre libx264-lossless_fast -scodec copy -padtop 132 -padbottom 132 out.mkv
I get
Code:
Output #0, matroska, to 'anr.mkv':

Ubuntu Multimedia :: Make Exact Video Quality Conversion With Ffmpeg?
Jan 3, 2010I spent about a half hour wrestling with different website tutorials about how to convert a file with ffmpeg and figuring out how to get all the video quality options right. Then I discovered you can just use the -sameq option and it figures it all out for you if you don't want to change the vid quality but just want it in another format. Thought I'd leave this on the site in case anyone else finds himself in the same boat.

Mar 1, 2010I'm trying to write a bash script for gpodder to automatically convert video podcasts to play on my media player. I'm using ffmpeg for the conversions (compiled myself with all codecs enabled). I'd like to avoid resampling the video or audio whenever it's unnecessary but ffmpeg seems to want to resample my video even if I only give it audio parameters to change.For example I have a test video with the following parameters:
Code:

Ubuntu Multimedia :: FFMPEG Scaling - Get Some Weird Green Band At Bottom Of Frame In Converted Video
Jan 14, 2011I've got a 1920x1080 video I've edited and rendered with Cinelerra, and I'm trying to use ffmpeg to transcode it to something smaller. However, when I use a command like this, for instance:
Code:
I inevitably get some weird green band at the bottom of the frame in the converted video. I know that there's some weird pixel stretching going on here, because the NTSC standard for 16:9 is 720x480 with rectangular pixels, and the 1080 version has square pixels, so I'm guessing the green band is an artifact of that process?

View 3 Replies View RelatedUbuntu Multimedia :: Ffmpeg Audio Merge With Video Merge
Feb 22, 2011I am using ffmpeg for merge wav files to a mov video. My doing is below
1. First extract audio (wav file) from video
2. Create wav file from mp3 track 1
3. Create wav file from mp3 track 2
4 Merge extract audio from video with track 1 and track2.
Now finally create a new video with original video's video stream and merged audio stream.
Process is working. However final video is 3-4 times greater than original one. I want that final video should be near about size of original video. As I understand, all three wav files (created from ) make video larger.

Fedora :: F13: Increase The Number Of Loop Device

Software :: Converting DVD Video With Mencoder
May 22, 2010I 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:
ffmpeg -i V-RedSky.nuv -croptop 4 -y -target ntsc-dvd -sameq -aspect 16:9 RedSky.mpg
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?
General :: Get A Shell Script To Loop Through A Number Of Directories And Subdirectories?
Jul 27, 2010I'm looking to get a shell script to loop through a number of directories and subdirectories,looking for files that contain a particular substring, and renaming the file by replacing the search string with a different substring. For example if you had a directory full of folders that contained digital photos (along with various other files which would need to remain unaffected), and the intent was to remove the "DSC_" prefix from several thousand files buried within. I've whipped up a rather long-winded solution that works well for this purpose but chokes on directory names with spaces. I am reasonably sure there's a 2 or 3-liner that would accomplish this exact same task.
