similar to: OGG theora with mono output

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, I'm switching from the mainstream theora trunk to the exp one and I encounter a problem with the encoder. Every video I encode are played like a 'mosaic', I do not know how to say that. The picture is just a bunch of coloured pixels. During the encoding process the video stream is defined like that: File stream.yuv is 320x240 15.00 fps 420 video. Why 420 ? Why not YUV like for

Hello. I'm trying to encode an Ogg Theora file from an unencrypted dvd using mplayer and encoder_example. I set up named pipes stream.wav and stream.yuv. I then run: mplayer -ao pcm -aofile stream.wav -vo null /dev/dvd & mplayer -vo yuv4mpeg -ao null -nosound /dev/dvd & encoder_example -v1 -a 1 stream.wav stream.yuv > lec1.ogg but I get the following error: File stream.wav is

Hi everyone, For your information, geexbox (http://geexbox.org) is now able to play OGG Theora files. Happy new year -- ZikZak

As far as video playback is concerned, it seems to mostly come down to how the video is compressed - although Gnash (the open flash player) still has a ways to go to play flash media as well as the closed source flash players. For the Colingo activity and library, we've found it very difficult to find optimum settings for flash and instead have decided to go with Theora. We've managed to

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

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.

Hello, Could you kindly point me to some instruction, how to encode demuxed files (.m2v and .mp2) to .ogg (Theora + Vorbis)? I was trying to use ffmpeg2theora, but I don't know, how to put two files to ffmpeg2theora (one audio an one video) and did not found, how to mux them into one file? Exist a way, how to do two pass encoding? I'm using Ubuntu Fiesty Linux. Thank you, Jiri Navratil

Hi, Here is a skin for the famous Java applet, it use PHP to select the file and other options. Could you add it as a link on http://theora.org ? http://menguy.aymeric.free.fr/theora/ All is in french but the php files are very easy to understand. Best regards -- ZikZak

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello For some reasons, I need to encode in mono a stereo wave file, as with the --downmix option from oggenc. I searched in speexenc man page and in the on line documentation, unsuccessfully. Of course I could first use something like sox to down mix my file, but it would be more practical to have an option directly in speexenc. - -- RIQUER

This patch adds a new option "channel-mapping" to opusenc which sets the channel mapping family used by the multistream encoder. Please let me know whether adding this option is worthwhile and whether the help string is okay. I tried to keep it short but accurate. The error message for an unimplemented channel mapping is "Error cannot create encoder: request not implemented".

Hello, I recently attempted to build theora 1.1.1 with mingw-w64-gcc 7.1 and msys and it fails to build the encoder_example.c example program. There are multiple declarations of the function 'rint'. The source file created its own version of the function that rounds AWAY from zero. MinGW-W64 has its own version of the 'rint' function, which does not round away from zero.

While integrating 1.1, I ran into some errors with my compiler and, after examining the code, saw what might be some invalid pointer math in opus_encoder.c. In optimize_framesize(), the first parameter 'x' is typed as opus_val16 and pointer math is done on the variable (in the 'if (buffering)' block) and then x is passed to the downmix function. I see that the downmix function uses

Hello, In one of my recent assignments, I was asked to develop a ogg player. I am not able to find the right repository of the source code. There are few repositories on vorbis but I am not clear which one is the right one for Windows environment. If somebody has successfully compiled any ogg player ever, his ideas will be helpful to me. In one of the code set, I was able to compile the

Hi I was surprised with size of Theora files and thought of feedback. Following 1minute duration Theora and Xvid files were made from a y4m file. The resolution is 1280x720: 1. Xvid 17MB 2. Ogg/Theora Q7 31MB 3. Ogg/Theora Q8 38MB 4. Ogg/Theora Q9 49MB 5. Ogg/Theora Q10 61MB The Xvid file was made using mencoder by 2 passes with following options:

Hi, We would like to announce the first release of the Speex project. Speex (http://speex.sourceforge.net) is an open-source (LGPL), patent-free compression format allowing an alternative to expensive proprietary codecs. Unlike Ogg Vorbis which compresses general audio, Speex is designed especially for speech. For that reason, Speex is meant to be a complement to Vorbis. Since it is specialized
