After a bunch of cumbersome testing I was able to transcode a Quicktime MOV file to OGG with theora and Vorbis. The method's a bit fumbly, but it works... It is automatable except for the initial audio decoding. Software used: Xine, oggenc, ffmpeg, ffmpeg2theora, oggzmerge Step 1: Get the video out of Quicktime ffmpeg -i infile.mov -b 5000 -f mpeg2video outfile.mpg Step 2: Get the video

Hi guys , I used ffmpeg , and ffmpeg2theora , with oggfwd for streaming to the icecast2 streaming server without any problems. But now , only works if I use ffmpeg2theora. I try with one of the latest svn version and one that I consider " stable" because is ok for all my needs , and they don't work. This is the complete shell output ffmpeg -i /home/pierpaolo/Scrivania/31.mpg

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

For last few days I was trying to learn ffmpeg and libtheora API. In the process, I have modified ffmpeg2theora code to include support for start time and end time. ffmpeg2theora -s 60 -e 130 file.avi will produce file.ogg which will be from 60th to 130th second of input file (something like -ss and -endpos in mencoder). This is a useful feature for someone who wants to cut a part of video

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

I''m converting videos to .flv but I can''t hear any sound. Is this ffmpeg command correct? ffmpeg -i #{path} -an -s 480x360 -vcodec flv -r 25 -qscale 8 -f flv -y #{flv} Thank you. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

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

Hi, I'm trying to get the following project to work : * acquisition from video acqusition card using vlc * vlc transcode to theora/vorbis and sends it to an icecast2 server Using VLC to acquire from the device is working ok. I get a stream in theora/vorbis format with audio & video sync'ed. Now, when I use VLC to send the stream to my icecast2 server, the stream mounts, it is

Hi folks,I'm joining this list because I've encountered difficulties with the ogg tools. I'm running Windows, and can't find binaries for liboggz tools, such as oggz-merge.exe Can someone provide oggz-merge.exe? So I use ffmpeg (v19289) for muxing ffmpeg -y -i sync2.ogg -i sync.ogv -vcodec copy -acodec copy sync2.ogv but the framerate fluctuates wildly on playback, and ogginfo

I've attached the command I ran, the output, and the crash log in the hope that it is useful. jason$ ffmpeg2theora -v 5 --optimize -A 64 -c 2 -H 44100 /Users/jason/ Movies/TV\ Shows/Holding\ Area/video.vob Input #0, mpeg, from '/Users/jason/Movies/TV Shows/Holding Area/ video.vob': Duration: 00:05:43.90, start: 0.211444, bitrate: 7217 kb/s Stream #0.0[0x1e0]: Video:

One thing I noticed though when reading about ffmpeg to make the h.264 was that for internet, you could use qt-faststart to move some stuff (I think called MOOV) to the front of the file allowing the file to start playing before it was finished downloading. That certainly helps quite a bit, I was wondering if there is a similar type of thing for theora? Theora files I host do not seem to

I agree I have not seen any H264 streaming info for icecast2. If you are however interested in using ogg/vorbis (Theora) look up Theora Streaming Studio in the Theora Cookbook and it will give you some info. Additionally if you wish to script this task you can look up the info on the three commands TSS wraps, specifically dvgrab/ffmpeg2theora/oggfwd. if your source file is in a h264 medium you

Thanks both of you for yours replys. I change my video source to theora with this comand: ffmpeg -i in.wmv -vcodec libtheora -sameq -acodec libvorbis -ac 2 -sameq out.ogg Now I have a theora video. How can I stream this video with Icecast2? Is there any guide? Thanks for all and best regards. 2010/8/12 E Ferguson Earnshaw <ferguson.earnshaw at gmail.com>: > I agree I have not seen any

Hello, We are working on the Radio station project and we are trying to implement the Live Video Streaming module using Icecast server with VLC player. We have installed and configured the Icecast into our server. Also, we have installed the VLC player in our local desktop computer. The USB webcam(200 CMOS UCAM - DLC220T) has been connected into my machine. Now we are trying to live video

After posting my previous mail, I realized that i should instead post a patch against HEAD. This is because v0.12 was released while I was also changing ffmpeg2theora.c from v0.11. So please use this patch instead and apply it to version at http://svn.xiph.org/trunk/ffmpeg2theora Nilesh Bansal http://www.cse.iitb.ac.in/nilesh/ -------------- next part -------------- Index: ffmpeg2theora.c
