I tried to install ffmpeg in trusty/Ubuntu 14.04 and got the following message:  $sudo apt-get install ffmpeg  Reading package lists...

I'm trying to render a video using blender, it have some images and sound, if I render it using just the default options I get no sound.  Searching on internet I found that I need to use other format than AVI JPEG to set some codecs options, I just have "AVI JPEG", "AVI RAW" and "FRAME SERVER". I'm keep looking but I can't found any information to solve my problem.  Im using fedora and actually I have  xvidcore-1.3.2-5.fc20.x86_64 ffmpeg-2.1.7-1.fc20.x86_64 packages installed.  EDIT: When I had the problem I had the last version of blender installed from , I also tried installing blender from dnf, also tried with , so  didn't solved my problem.

I am a huge fan of . It is the epitome of simple. Select a video file (or DVD), select a preset, select an output path, click Start. A certain amount of time later relative to the size/quality of the content, and you have yourself a pretty much perfect video file suitable for the medium of your choice.  I've been looking for similar qualities in an Audio Converter, and more preferably, an Audio Extractor (from a given video file). I would love to be able to drag a video file into an application, specify that I want the Audio File in AAC at a given bitrate, click Start, and let the app do the rest.  I am not averse to using Handbrake to suffice the conversion aspect of this, so long as the audio extraction after the fact is a simple process. The point is to take as few steps as possible.  Any tips? Apps? Ideas?

I received 4 .mov files from a client that they want on their mobile website via SlideShowPro. Each original file was between 200 and 400 mb. I've gotten each one down to about 30 mb using transmageddon as described , but that's still really big for a mobile connection.   Is there any way to shrink them even further? Maybe it's the settings; I used Output Format = MPEG4, Audio = AAC, Video = H264 (which is what is suggested by SlideShowPro.)

I would like to scale a watermark to 5% of the video width.  I need something like that:  ffmpeg -i 1.mp4 -i logo.png -filter_complex "[1:v] scale=1_MP4_VIDEO_WIDTH*0.05:-1 [logo1]; [0:v][logo1] overlay=0:0" -y -b 1600k -c:v libx264 -profile high -level 4.1 -c:a libfaac -q:a 128k 2.mp4   How can I reference the video width?

Does anyone know if there are any video formats (besides the HUGE uncompressed avis) that you can render in that maintain the alpha channel? (i.e. for after FX etc.)   I used to use quicktime, but that's no longer an option.  I know you can render in png. or other image formats, but video is significantly smaller, and I often work on machines with less space &amp; resources.

My Canon 60D creates .MOV files when recording video and I've found out that the .MOV container has an H264 video stream and a PCM audio stream.    I've used ffmpeg and GSpot to look at some of my videos, and I see what seem to be pretty high bitrates (22,000kbps for 640x480, 45,000 for 1920x1080).  I'd like to reduce the size of the files, but keep the quality quite high.  I've played around with the simplest thing I could think of, reducing the bit rate and that does what I'd expect: cut the bitrate in half and the file size is about half.  But I'm wondering if there's a way to determine a "good" target bitrate, or if there's any point in trying to do variable bitrate.

This should be pretty trivial, but I can't find a way to get it to work.  I want FFmpeg to take one JPEG image and an audio file as input and generate a video file of the same duration as the audio file (by stretching the still image for the whole duration).  I don't care very much about what video codec is used for output, but it is vital that I can use "copy" as the audio codec (i.e. copy the audio stream without transcoding it).  What is the right command line that would do that?  I tried:  ffmpeg -i image8.jpg -i sound11.amr -acodec copy test.avi   and tried a lot of combinations with and without -s 640x360, -loop_input, -shortest, -t xxx, -r 0.1 (artificially low frame rate in the hope that the video would be longer) and -f image2  Either I get errors or I get a video file of the duration of one frame.  I've googled around and found a dozen of proposed solutions (supposedly to this very same question) none of which works.  Can anybody suggest a working command and explain the rationale behind it?

How do I split a 7GB (movie) file into smaller files of (say) 1GB, and then (in another Ubuntu computer) integrate them to get the original file (using just bash commands)?

Is there any FREE software that I can use to convert a MP4, AVI or MOV file to a collection of images that are GIF, JPG or PNG?

i want to split a video file by size using ffmpeg.  Do you know how to do that ?  Do i have to calculate the duration that corresponds to each size ?  Thank you.

Is there a simple way to do something like..  [NSMagicDataConverter humanStringWithBytes:20000000]   ..which would return "19.1MB"?

I found this example   ffmpeg -i input.mkv -filter:v "setpts=0.5*PTS" output.mkv    but I have a video I want to speed up by 60 times, not just 2X.

I have an mp4 video file with multiple audio tracks. I would like to strip away the rest of the tracks and keep just one. How do I do this?

Situation  I have obtained some blender files &amp; licences for 3d models of transit vans and some trucks. Currently, when I export these objects to .obj files they are rather large, take a while to render and look to have been built in segments.  Problem  These models need to be used on Android devices and they need to be observable through one .obj file. What is happening is when I open the .obj I am not seeing the same model as I do in Blender. The doors and wheels of the vans for instance don't appear.  End Product  I need to find a way of reducing these models to be just one single object. Items on the interior of the van don't matter, seats for example. The file would ideally also be around 200kb, and exportable in a single .obj file. Can anybody shed some light on how I would go about doing this?
