Hey guyz, Well basically what i am trying to do is get ruby to read my video files in so that i can get the dimensions of the video and then place the dimension sizes in my view. The two formats i need to do this with are mpeg4 (h.264) and FLV. Is there anyway i can get rails to access the metadata of these formats and pull the dimensions from the metadata? Any help would be greatly

I am using theora_encode along with ffmpeg: ffmpeg -an -s 1920x1080 -r 24 -i bigbuckbunny.mp4 -vcodec rawvideo \ -pix_fmt yuv420p -f rawvideo - 2>/dev/null \ | ffmpeg -an -f rawvideo -s 1920x1080 -r 24 -i - -f yuv4mpegpipe - 2>/dev/null \ |* theora_encode /dev/stdin 2>/dev/null *| ffmpeg -y -f ogg -i - \ -f mp4 -i bigbuckbunny.mp4 -map 0:0 -map 1:1 -vcodec copy \ -acodec libvorbis -ab

Basically i am wondering how to call ffmpeg in rails so i can read video files in order to get their properties? My goal is to have ffmpeg read thru a list of video files and then take their properties and place these properties along with the name in a sql table. -- Posted via http://www.ruby-forum.com/.

Hi, and thank to you all for this great codec ! I have this bug on Debian Lenny with compiled packages of last svn versions of ffmpeg and libtheora. This seems to append only on the amd64 arch. Here is a valgrind log : pre-barreau at augustins:~/video$ export LD_LIBRARY_PATH=/usr/local/lib pre-barreau at augustins:~/video$ valgrind /home/pub/apps/ffmpeg_dev/ffmpeg_svn/ffmpeg -i

CentOs zoneminder users, I have been trying to install zoneminder on Centos 5.3 (2.6.18-128.1.16.el5xen) and have hit a brick wall with ffmpeg which zoneminder has as a dependancy. There were no rpm's in centos or rpmforge so I have followed the instructions on the zoneminder website for a CentOs install. I have posted a note on the zoneminder list, but have not been able to get any takers

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?

If neither --enable-ffmpeg nor --disable-ffmpeg was given, try to find ffmpeg. If it wasn't found, print the warning, but don't fail. If --enable-ffmpeg was given, fail if ffmpeg is not found. If --disable-ffmpeg was given, don't print the warning, as the user already knows that ffmpeg won't be enabled. It's important that ffmpeg is not viewed as a hard requirement, as

I have a matrix y: > dimnames(y) $x93 [1] "1" "2" $x94 [1] "0" "1" "2" .................. so on (there are other dimensions as well) I need to access a particular dimension, but a random mechanism tells me which dimension it would. So, sometimes I might need to access dimnames(y)$x93, some other time it would be dimnames(y)$x94.. and so

Hi Fred. Appreciate your response. Maybe in my explanation I have some red and green apples, but I can agree that my understanding is as you explained it. 😊 The point is that if I can successfully stream mp4 with H.264 and AAC encoding without any issues to icecast, I can then use ffmpeg to turn it into HLS which then solves my iOS support issue. The CPU cost of repackaging MP4 into HLS

We're trying to build a rich media website, and will need to re-encode the video content with ffmpeg. Unfortunately, the ffmpeg version that comes with the most common repos are rather out of date.

Hi, I'm the founder and still very active developer of Puppy Linux, and a variant named Quirky. Puppy is a cut-down distro, typically 100MB live-CD. We have always used the Adobe Flash player, though I have stayed with the Flash 9 player (9.0.48.0) due to its smaller size. Puppy also has ffmpeg, xine-lib and gxine. Recently I have been experimenting with Swfdec and Swfdec-mozilla. I started
