<p>I guess it didn’t take my comment. I was wondering if there was a way to turn images into video, but, by specifying a range of images… i.e. image50 – image500 . only converting those images?</p>

<p>I only use ffmpeg with xine. I thought it was a library but it seems it is also a command line tool. And a very powerful at that.<br />

Thanks a lot.</p>

<p>@damien: I don’t know why but Akismet flagged your comment as spam…Btw, I never tried to start of at image50.jpg, but I’m pretty sure that it will work if you define a integer shell variable named d which have 50 as a value.</p>
|
||
<p>@Olivier: You can use ffmpeg both as a command line tool, or as a library. I’m pretty sure that Youtube uses it to convert mpeg and avi videos submitted by its users to the flv files they displays on the site.</p>

<p>How would you define that in a command line? How about doing btws? Between image50 and image500? I know this is a lot to ask, but thanx for replying and your help!</p>

<p>iPhone question (yeah, yeah, I know). From looking online it appears that the iPhone can play XVID/DIVX files, since they’re basically MPEG4. Does anyone know a way to do a fast transcode? Leave the data the same, just change the bare minimum (headers/container) so that iTunes will import and sync it to the iPod? It’d take up more space, but it would take minute or so to do an entire (for sake of argument, mind you) TV show that you found on the intertubes.</p>
|
||
<p>(And thanks for the reminder on FFMPEG – I needed something like that last night)</p>

<p>@ jbj</p>
|
||
<p>I have images in sequence that look like this:</p>
|
||
<p>image00001.jpg</p>
|
||
<p>all the way to image05000.jpg</p>
|
||
<p>I tried doing the code up there but nothing. I get an error. Here’s what i tried:</p>
|
||
<p>ffmpeg -f image2 -i image%d.jpg video.mpg</p>
|
||
<p>I get this error: </p>
|
||
<p>image%d.jpg: I/O error occurred<br />
|
||
Usually that means that input file is truncated and/or corrupted.</p>
|
||
<p>What’s interesting is if i change the file name to 001.jpg and so on, it works. I really don’t have control of what the jpg name is going to be so how do i get it to work with that naming convention? Thanx again!</p>

<p>Thanks for the recipe, but can’t encode tv show to mp4 ipod. I get “Unable to find a suitable output format for ‘input’” error. Tried on Ubuntu and FreeBSD, video is:<br />
|
||
Input #0, avi, from ‘Eureka.avi’:<br />
|
||
Duration: 00:41:56.8, start: 0.000000, bitrate: 1157 kb/s<br />
|
||
Stream #0.0: Video: mpeg4, yuv420p, 624×352, 23.98 fps(r)<br />
|
||
Stream #0.1: Audio: mp3, 48000 Hz, stereo, 128 kb/s<br />
|
||
Maybe, I need to install something else? I updated ffmpeg to the latest. Is there an option for dynamic scaling, or the tool can calculate it?</p>

<p>@15 – v3g: “input” is a typo – just delete it. The OP is using the command line from the ffmpeg documentation, which uses “input” as a placeholder for the name of the input file.</p>
|
||
<p>Also, if you get an error about not having the aac codec, use libfaac instead.</p>

<p>Thanks, now its working, but the quality is awfull:<br />
|
||
ffmpeg -i xxxxx.avi -acodec libfaac -ab 128kb -vcodec libx264 -b 1157kb -mbd 2 -flags +4mv+trell -aic 2 -cmp 2 -subcmp 2 -s 312×176 -title X xxxxx.mp4</p>
|
||
<p>Input #0, avi, from ‘xxxxx.avi’:<br />
|
||
Duration: 00:41:56.8, start: 0.000000, bitrate: 1157 kb/s<br />
|
||
Stream #0.0: Video: mpeg4, yuv420p, 624×352, 23.98 fps(r)<br />
|
||
Stream #0.1: Audio: mp3, 48000 Hz, stereo, 128 kb/s<br />
|
||
File ‘eureka.mp4′ already exists. Overwrite ? [y/N] y<br />
|
||
Output #0, mp4, to ‘xxxxx.mp4′:<br />
|
||
Stream #0.0: Video: libx264 (hq), yuv420p, 312×176, q=2-31, 1157 kb/s, 23.98 fps(c)<br />
|
||
Stream #0.1: Audio: libfaac, 48000 Hz, stereo, 128 kb/s</p>
|
||
<p>And that worked on FreeBSD, not Ubuntu. For vcodec mpeg4, I couldn’t change the width and height, but only with libx264. And still doesn’t work with Ubuntu.</p>
|
||
<p>How do you change the quality, something like ‘q=2′ or ‘q=9′?</p>

<p>Does anyone know if ffmpeg supports transparent images ? I’m trying to put a sequence of PNGs into a .flv or .mov movies but the transparent parts of the images become black. I searched on Google but can’t find any solution.</p>

<p>Hi! Thanks a lot for this pre-chewed tutorial! The only thing is that I came across errors when trying the command to convert a video to the iPhone/iPod format.</p>
|
||
<p>I was able to fix it by removing the word “input” from the command line. Worked perfectly after that. Just wanted to share that with everyone!</p>
|
||
<p>Merci encore!</p>

No one can help w/ with such a vague question. It would help if you provided the context of the command you are trying to execute and the resulting error.</p>

<p>Using ffmpeg on our linux server to convert user uploaded videos to FLV. Sort of like a YouTube.</p>
|
||
<p>I am not satisfied with the quality, and know there has to be a better way. I have tried several changes, but am not getting where I would like it to be. As good as YouTube.</p>
|
||
<p>Please see my command line below, and suggest any changes I can make to improve the output quality.</p>
|
||
<p>Please keep in mind that the uploaded “user.fil” could be an flv,avi,wmv or a mpg.</p>
|
||
<p>ffmpeg -i user.fil -acodec libfaac -ab 156k -b 1024k output.flv</p>
|
||
<p>Thank you for any help you can give, and this is a GREAT cheat sheet. I will keep a copy by my side!!!</p>

<p>Well, I think I got it.</p>
|
||
<p>All I did is add the format key, and the results were 100% better. So remember this.</p>
|
||
<p>BAD – ffmpeg -i user.fil -acodec libfaac -ab 156k -b 1024k output.flv</p>
|
||
<p>GOOD – ffmpeg -i user.fil -acodec libfaac -ab 156k -b 1024k -f flv output.flv</p>

<p>Hi All…I can see there is some experts in ffmpeg in this blog…<br />
|
||
I’m using ffmpeg in order to compress a continuous streamed mpeg2 retrieved from a dream box machine (satellite receiver)<br />
|
||
I want to compress each minute in a separate file…<br />
|
||
I’ve used the -t option, but in fact I’m loosing some gaps between each consecutive files<br />
|
||
this is the script i’m using:</p>
|
||
<p>while test 1=1<br />
|
||
do<br />
|
||
ldt_now=”$(date +”%y-%m-%d-%H-%M-%S”)”<br />
|
||
ffmpeg -t 60 -i “http://IP…” /home/grabbing/file_compressed_for_$ldt_now.mpg<br />
|
||
done</p>
|
||
<p>I’m wondering if any one can give me any hints regarding how to output from ffmpeg in different consecutive files without having any lost gaps</p>
|
||
<p>Any help will be very appreciated<br />
|
||
TIA<br />
|
||
Rabih</p>

<p>Hello, </p>
|
||
<p>thanks for the samples.</p>
|
||
<p>I think you should add a command to convert mp3 for iphones/ipods, this article is number one on google for linux convert mp3 for iphone.</p>
|
||
<p>PS: fix a typo for IPpod and add a copy command flash button like on github for urls.</p>

<p># rename files sequentially for FFMPEG to work properly<br />
|
||
counter=10000<br />
|
||
for f in *.jpg; do<br />
|
||
let “counter+=1″<br />
|
||
mv $f screen${counter:1}.jpg<br />
|
||
done</p>
|
||
<p>this will rename a set of files continuously from 0001 then do something like<br />
|
||
ffmpeg -i screen%04d.jpg outputmovie.mp4</p>
|
||
<p>and a question. what is the ffmpeg command to capture a snapshot from the webcam? just a jpg? or is another library better for that?</p>

<p>thanks,<br />

<p>Thanks for the code snippet dan.</p>
|
||
<p>I modified it to make symlinks to images one level up. Make video from links in the directory. No need to rename your data to fit with one time use.</p>
|
||
<p>Runs in linux.</p>
|
||
<p>#!/bin/sh<br />
|
||
# This will make a set of symlinks to files in directory<br />
|
||
# one level up continuously from screen1.jpg screen2.jpg …<br />
|
||
# The total is displayed on the terminal command prompt.</p>
|
||
<p># Then you say something like<br />
|
||
# ffmpeg -r .2 -i screen%03d.jpg outputmovie.mp4<br />
|
||
# or<br />
|
||
# ffmpeg -r 24 -b 1800 -i screen%03d.jpg output.mp4<br />
|
||
# moB 16 Oct 2010</p>
|
||
<p> no=0</p>
|
||
<p># edit this line to select files: S1* or *.jpg …<br />
|
||
for f in ../*.jpg; do<br />
|
||
no=$((no+1)); linkname=screen</p>
|
||
<p> if [ "$no" -lt "10" ] ; then linkname=${linkname}00<br />
|

elif [ "$no" -lt "100" ] ; then linkname=${linkname}0<br />

<p>Hello, All!</p>
|
||
<p>I’m using custom ffmpeg commands on a Drupal website for automatic conversion of uploaded files. It converts various file types to mpeg-4 (H.264) and is working fine. I need to add a simple slow motion to this process – simply repeated frames. In other words, I need a command to convert a video file with the following frames (A, B, C…) to (A, A, B, B, C, C…) for a 50% slomo.</p>
|
||
<p>If there’s some fancy way to do it with interpolation that would be even better, but for now I’ll settle for frame duplication.</p>
|
||
<p>Thanks in advance!</p>
|
||
<p>-James</p>

|
||
<p>why not just halve the frame rate? If you know the frame rate of the input files just divide it by 2 (or whatever number you like). Has the advantage of not increasing your file size, or needing any recompression.</p>
|
||
<p>ffmpeg -i input.mp4 2>&1|grep Video|sed “s/.*kb\/s,[[:space:]]*\([0-9\.]*\).*/\1/”</p>
|
||
<p>gets the fps from the metadata (the sed expression is good for Mac/Darwin, on linux or other OSes it may need tweakage).</p>

<p>Hello,</p>
|
||
<p>I’ve been trying to convert a .flv file I got from youtube and convert it to a .mp4 file playable on my iPod but can’t seem to make it work. I type in:</p>
|
||
<p>ffmpeg -i sniper.flv -acodec aac -ab 128kb -vcodec mpeg4 -b 1200kb -mbd 2 -flags +4mv+trell -aic 2 -cmp 2 -subcmp 2 -s 320×180 -title X sniper.mp4</p>
|
||
<p>but it gives me the following message:</p>

<p>Thanks Jean, useful post.<br />
|
||
One query about the audio-video mix command?</p>
|
||
<p>ffmpeg -i son.wav -i video_origine.avi video_finale.mpg</p>
|
||
<p>Will this mix or replace embedded audio with new audio file?, is there any specific command to achieve that? i.e. completely delete the existing audio in video and replace with a new file?</p>
|
||
<p>Thanks a lot,<br />
|
||
Sohel</p>

<p>Hi,<br />
|
||
I am looking for the conversion of .mov file to avm2 swf file, but it seems .mov file not supported well in ffmpeg. If I use the -an switch in the conversion command then it create the avm2 swf file. But i need the audio conversion as well.</p>

<p>OK… stupid newb question….</p>
|
||
<p>How do I convert a whole directory full of videos as a batch, ie: video01.mp4 to video01.avi ….. video25.mp4 to video25.avi?</p>
|
||
<p>This is the command that I’m using right now to convert 1920×1080/60i h.264 video with 128kb AAC sound to standard def at 30 fps rather than the 60. Makes a big difference in the file size, and uncompressing seems to make it play a lot smoother. Mostly though, I want to be able to edit it in an NLE like Kdenlive (haven’t tried PiTiVi… maybe I should) so that I can cut stuff, add titling, etc.</p>
|
||
<p>ffmpeg -i HDV_0028.MP4 -s 720×480 -r 29.97 -vcodec mpeg4 -acodec libmp3lame -ac 2 -ab 128000 -aspect 16:9 -b 15000k HDVsd_0028.avi</p>
|
||
<p>Any help is appreciated!</p>
|
||
<p>Thanks,<br />

<p>@Derrick,</p>
|
||
<p>I don’t know if ffmpeg suppose this however, it should be easy to script. Something like:</p>
|
||
<p>#/bin/sh<br />
|
||
for i in $(ls video*.mp4)<br />
|
||
do<br />
|
||
ffmpeg -i -$i s 720×480 -r 29.97 -vcodec mpeg4 -acodec libmp3lame -ac 2 -ab 128000 -aspect 16:9 -b 15000k $i.avi<br />
|
||
done</p>
|
||
<p>Regrads,</p>

<p>@BlackSheep: Only just seen this so you’re probably long gone, but in case anyone else is interested, here’s the command I use to code any video into .3gp format:</p>
|
||
<p>ffmpeg -y -i $1 -vcodec mpeg4 -s 480×320 -r 15 -b 700k -acodec libfaac -ac 2 -ar 32000 -ab 64k -f 3gp $OUTFILE</p>
|
||
<p>Change the 480×320 to the size required.</p>

<p>Can any one please help me to write the command to make .jpeg from .flv through ffmpeg ?</p>
|
||
<p>$fromdurasec=”10″;<br />
|
||
$ffmpegpath = FFMPEG_PATH;<br />
|
||
$input = “video_file/orig/Lady.flv”;<br />
|
||
$output = “video_file/thumb/Lady.jpeg”;<br />
|
||
$command = “$ffmpegpath -i $input -an -ss 00:00:$fromdurasec -r 1 -vframes 1 -s 80×80 -f mjpeg -y $output”;</p>
|
||
<p>The above works fine for .mpg and etc, but not for .flv files.<br />
|
||
Please help me to find out the command to make .jpeg file out of a .flv file.</p>

<p>Hello,<br />
|

Does anyone knows how to limit the process of ffmpeg.exe to only 50% of the CPU, to avoid the CPU to stay on 100% on every conversion.<br />

Tks<br />

<p>With regards to personal preference, pragmatism, and/or programming syntax/structure, is there any particular reason why these 19 pearls aren’t bundled in a “user-friendly” gui? I have struggled so much with various versions of Linux but refuse to give up. I just have to scratch my head and wonder what is the attraction for the purist who prefers line commands. Is it just me or has anyone else noticed how the body of human knowledge has quickly and greatly expanded as we went from dial-up BBS to graphically rich internet content?</p>

<p>Say for example, you had 10,000 mpegs that you wanted to convert to avi. Would you want to use a gui to do that? I think not. No, one would use the CLI and likely wrap a bourne, bash, perl or python script around it and be done with it.</p>
|
||
<p>What if you want to convert an mpeg to avi automatically at some time of the day as part of an unattended process? GUI? Nope. A script and a cron job.</p>
|
||
<p>Another extremely powerful linux/unix command is xargs. Google it. Learn how to use it. Then maybe you’ll begin to appreciate the power of the shell.</p>
|
||
<p>GUIs are wonderful. But there are a multitude of examples of tasks which are better performed from the shell. This page provides excellent recipes which can easily be embedded in scripts.</p>

<p>I am trying to create a video with dyamically generated images, which are stored in database.</p>
|
||
<p>eg: http://localhost/image/id/20<br />
|
||
http://localhost/image/id/21<br />
|
||
http://localhost/image/id/51 etc.</p>
|
||
<p>Can I create video with these kind of images or by getting them directly from database.<br />
|
||
I’m using ffmpeg-php library. Its documentation says we can use ffmpeg_animated_gif. But it doesn’t look like exist anymore.<br />
|
||
So help here would be great. </p>
|
||
<p>Many Thanks.</p>

<p>PHPTribe,</p>
|
||
<p>I would keep it very simple.</p>
|
||
<p>Write your php code so it looks thru your database, and copies the images you want to turn in to a video, to a “Temp” directory, while also renaming each image to “image1″, image2, image3… and so on.<br />
|
||
For example: copy /image/id/21.* /temp/image1. (very easily done with a “While Statement”.)</p>
|
||
<p>One issue is, they all need to be of the same type. .jpg, .bmp, .gif</p>
|
||
<p>Then use the above example: ffmpeg -f image2 -i temp/image%d.jpg video.mpg</p>
|
||
<p>Then have your code clear out the temp directory.</p>
|
||
<p>This is just a thought. Not sure exactly how you plan to implement.</p>

<p>You should try out http://transloadit.com – it can convert all videos for you without you having to install the tools or find a webhost with ffmpeg.</p>

<p>Heya. Having an issue while trying to merge a FLV video (consisting of a single picture file looping for 1,5h) with a MP3 file, basicly trying to create a video of a podcast-mp3 with a single static picture as the only visual element.</p>
|
||
<p>Got the 1,5h picture FLV working with [ffmpeg -loop 1 -i picture.jpg -t 01:22:16 -r 1 -vcodec flv -an film.flv]</p>
|
||
<p>But when trying to merge these by using [ffmpeg -i film.flv -i podcast.mp3 -acodec copy -vcodec copy podcastvid.flv]</p>
|
||
<p>.. it ends up with: [flv @ 00000000040517D0] Application provided invalid, non monotonically increasing dts to muxer in stream 1: 304327 >= 304327 av_interleaved_write_frame(): Invalid argument</p>
|
||
<p>No idea how to try this otherwise <img src='http://www.catswhocode.com/blog/wp-includes/images/smilies/icon_sad.gif' alt=':(' class='wp-smiley' /> </p>

|

<p>How about the delay between images? If I want to have e.g. 3 seconds for each image?</p>

<p>Hi everyone,</p>
|
||
<p>I’m trying to decode an mp4 stream to its frames and extract information about Motion Vectors and DC coefficients for each MB of the frames. Does anyone can help?<br />
|
||
Could -debug mv and -debug dc_coeff provide the necessary information? how can i properly use them?</p>
|
||
<p>Thanks</p>

<p>every server config is different… and the video conversion to mobile quality vid wasn’t working as I was expecting it to, after some research and some work on this I came up with this:</p>
|
||
<p>ffmpeg -i original.mp4 -acodec aac -strict experimental -ab 128kb -vcodec mpeg4 -b 1200kb -mbd 2 -flags +4mv+aic -trellis 1 -cmp 2 -subcmp 2 -s 320×180 new_mobile.mp4</p>

<p>There’s an error in the extract video and convert to MP3 part: “-ab 192″ should be “-ab 192k” instead<br />

Don’t know if an audio at 192 bytes/s would be audible…</p>

<p>I have a device that dumps blocks of fixed-length uncompressed audio samples at 48kHz in signed 16-bit LE format and I would like to use this as input to FFMPEG so that it can multicast an audio stream via RTP (it doesn’t have to compress the data on output, but if it does it should use something like MPEG-1 L2 ES format). Can you help me understand how this can be done with FFMPEG? I can interpose a simple pipe between the device and FFMPEG if necessary.</p>
