i?m fairly new to ruby... any suggestions getting the below to work... i?d like to use myfile_field.read within encodeVideo and then self.data = Student_Interviews.flv class Myfile < ActiveRecord::Base . . . def encodeVideo opts #, stream IO.popen(?ffmpeg #{opts}?, ?w?)#{ |io| io.puts stream} end def myfile=(myfile_field) if myfile_field and myfile_field.length > 0 encodeVideo ?-i

This is resolved: apt-get remove libspeex-dev cd ~/src/speex-1.2rc1/ ./configure --prefix=/usr make; make install cd ../ffmpeg ./configure --enable-libspeex make; make install worked; then I was able to decode a Speex .flv file: ~/flvs$ ffmpeg -i SpeexQ6R16Efalse.flv foo.wav FFmpeg version SVN-r17174, Copyright (c) 2000-2009 Fabrice Bellard, et al. configuration: --enable-libspeex

I''m converting videos to .flv but I can''t hear any sound.

I tried to encode two minutes from an AVI DV file 720x480: ffmpeg latest release produces a FLV 320x240 25fps 360k video 40k audio in about 45 sec. ffmpeg latest release produces an OGG 320x240 25fps 360k video 40k audio in about 1:20 sec. ffmpeg2theora the same in about 2 minutes or more. The FLV quality it's quite good, some dropped frames maybe. I was wondering to know if ffmpeg team

Hi all, I just did a brief test with 3 different codec combinations: 1) ffmpeg sorenson/flv, mp3 audio in flv container 2) ffmpeg h264/vorbis audio/matroska 3) ogg/theora/vorbis using encoder_example Here are the results: 10721201 2010-10-16 14:46 origem1.flv 20731108 2010-09-13 23:04 origem1.mkv 33101703 2010-10-03 11:24 origem1.ogv as you can see, flv wins hands down, and it doesn't look

I am having trouble compiling ffmpeg to support speex, which didn't work with the ubuntu libspeex-dev package, but looks like it might with the Speex version 1.2rc1 tarball from http://speex.org/downloads/ How do I tell ffmpeg's configure and/or make to use the 1.2rc1 version of libspeex in /usr/local/include instead of the older debian/ubuntu libspeex-dev package in /usr/include/speex?

Hello, I basically have the following problem - I have a site that will allow people to upload videos. The video may be in any format - .mov, .avi, .wmv etc.. I can either use embedded Windows Media Player, or embedded Quicktime to play the files but the problem is, how do I create stills from the movies to display them as .jpg''s on my site so when somebody clicks on them, the video

Im using a customs processor to run ffmpeg on a video to create a thumbnail. So far so good. Except when I do: cmd = "-i #{@file.path} -f flv -s 320x240 ~/Downloads/foobar/q.flv" success = Paperclip.run(''ffmpeg'', cmd) Console is reporting: ffmpeg ''-i /var/folders/uL/uL0bYOOZEZaJH5E+BmDJVE+++TI/-Tmp-/stream, 16824,1.mpeg -f flv -s 320x240

Hi, Firstly thanks for great job done with swfdec. I had recognized swfdec at gtk.org site. Last week i decided to integrate it to gtk+webcore browser. And i successfully did it with version 0.4.5 Even thought it is integrated and works fine there are some problems with swfdec. I want to ask some questions about it. Also yesterday i saw the last release 0.5 And i have some questions about it.

rtmplite -- http://code.google.com/p/rtmplite/ -- can be used to record Speex .flv audio and a/v files from Flash/Flex applets, and ffmpeg can be used to extract the Speex audio from such files, which can also be replayed on Flash. > Date: Tue, 23 Aug 2011 14:53:52 -0700 > From: Jozsef Vass <jovass at adobe.com> > > The only way to do this is to publish from Flash Player and

I wish to transcode an AVI from 29fps to 15fps theora. I have tried many combinations. The nearest I have so far is to: 1) ffmpeg -i input.avi -f avi -vcodec rawvideo -acodec pcm_s16le -r 15 -ar 22050 -ac 1 intermediate.avi then 2) ./ffmpeg2theora-0.15.linux.bin -f avi -c1 -H 22050 -o out.ogg intermediate.avi This gives me an output I want, however, the intermediate uncompressed stage

In my app i upload a file, convert it with ffmpeg, delete the original and make a small thumbnail out of the big thumbnail ffmpeg makes. At the moment it seems like these actions are tripping over each other - how can i make the app wait until ffmpeg has completed it''s output before doing the next thing? -- Posted via http://www.ruby-forum.com/.
