similar to: Quicktime 2 Theora Transcoder's Nano-Howto

Hi, I sent the message below a couple of months ago but I got no reply. Now that there's more activity perhaps someone could kindly provide me some guidance. Theora is great and the developers are doing a wonderful job, so I'd like to implement the codec in a way which does it justice... Original post: I wrote a plugin to enable LiVES (a video editor) to encode theora/vorbis/ogg files.

Hi, I would like to create a movie out of a lot of png files. Using mencode I would do have something similar to mencoder "mf://*.png" -mf type=png:fps=5 -vf spp,scale -ovc lavc -o output.avi but I want to have an ogg format. I.e. an ogg movie How to do it? convert can convert the pngs to an mpg but not to an ogg! convert: unable to open module file

I had some shows on tivo that I figured I wanted to keep on a CD in case I might ever want to watch them again. (Not that you care, butthis really is for my own personal use. I wouldn't have the bandwidth to "share" this stuff even if I wanted to.) So I downloaded a 1 hour show with TiVo ToGo, and I jumped through a few hoops to "free the mpeg", and I got a nice 2 GB

hi everyone! i'm playing around with theora streaming for the linux audio conference 2005 (http://lac.zkm.de). i checked out svn.xiph.org/trunk, built all ogg, vorbis, speex and theora related libs from scratch, then pulled icecast-2.2.0. three issues: [1] icecast runs fine as always, but when i do cat myvideo.ogg | oggfwd myhost 8000 mypasswd /test.ogg, the stream dies after a few

Hello, I would like to add a introduction video (typically a title with fade-in / fade-out) at the beginning of an Ogg/Theora video. I generated this intro video in Ogg/Theora from a sequence of png files. I would need to do this in an automatic script, because I have many such videos to process, and without doing any re-encoding step (which would be very costly because my videos are huge). I

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 think we are likely to settle for CMML for everything text in Ogg. Of course,

Is there a program currently available that will correctly mux a52/ac3 streams and theora streams into an ogg container? I've tried oggzmerge, and it will mux ac3 into ogm and correctly create a new ogm from an existing theora file, but it doesn't seem to put the two together correctly.

i have a theora video file and vorbis audio file, how i mux it into the ogg container?

Hi, I would like to create an output file with mono audio. How to do it ? If use a video with mono as input, the result will be a video with stereo. Is there a way to use the --downmix from oggenc ? Regards -- ZikZak

Hello all - I'm out of my element with multimedia, can anyone point me in the right direction? I've a pchdtv-3000 card I am trying to record from. I can successfully record audio/video using streamer or watch television with audio using tvtime, so I know the audio is there. I want to record directly to theora. I am trying to do so using ffmpeg2theora like so: ffmpeg2theora --v4l

dv file from minidv camera - interlaced. small dv created by imported jpeg images - not interlaced. seems that when I use ffmpeg2theora with deinterlace switch and reduce size, it works. But when the only reduction I am doing is to width (720x480 -> 640x480) the encoder ignores the naturally interlaced bit and uses the last de-interlaced frame. Since the small bit made from jpegs is a dv

Hi Folks, What is the proper way to embed text stream into the Ogg stream? I need to have text information (lyrics as example) recorded together with the audio. Is there a standard mechanism for that? What is the right way to do it?
