similar to: Add an intro to a theora file without re-encoding?

hi guys, first of all, i'd like to ask if there any crossplatform software/service ( gui is also better, an online application like firefogg is great, or at least a command line tools for any platform) to combine theora videos, other than oggcat... i am doing some art projects that people should be able to remix featured theora videos and i find oggcat very usefull in theory but not in

Hi Yorn, all files can be found at http://firefogg.org/~j/oggmix/ audio.ogg and video.ogg are create with oggCat: oggCat audio.ogg audio_01.ogg audio_02.ogg oggCat video.ogg video_01.ogg video_02.ogg oggJoin.mix.ogg is made with oggJoin: oggJoin mix.oggJoin.ogg video.ogg audio.ogg mix.oggz-merge.ogg is made with oggz-merge: oggz-merge -o mix.oggz-merge.ogg video.ogg audio.ogg in my

hi, trying to join audio and video tracks that have been itself composed from several ogg files with oggCat, i get a file that does not work. that happens both with oggz-merge and oggJoin. the files produces by oggCat look ok according to ogginfo / oggz-info / oggz-validate, they also play fine in all players. anyone got an idea what could cause that problem? i can put up some sample file if

Hello everybody ! I am working on a php class to enable, on the server-side, to extract useful data from Ogg theora videos. http://opensource.grisambre.net/ogg . I need to have it extract a thumbnail picture from a video (much like dailymotion or youtube). Right now, I am doing it using the ffmpeg-php extension (for picture extraction only), but the problem is that this module is available on

Hi there, I haven't been on this list until now, so I wasn't aware of this problem until last night ;-) - sorry for that. I am working on a patch for oggCut for that issue (looks good actually but I would like to do some testing befor I can release a patch.) Normal players are not effected by the page time misordering, so I took this issue as "minor". The reason for the

hi yorn and all, thank you oggvideo tools for windows. it is great... i can live with the command line for now myself but i will need to make some art students work with oggvideotools and they may not be happy with that:D anyway your video tutorial is also good (but it also crashed my firefox 3.5 beta 4 for two times on windows and i have reported that to mozilla), i would love to help for that

Hey all, it took me a while, but now I have opened sourceforge project for the Ogg Video Tools with SVN support: https://oggvideotools.svn.sourceforge.net/svnroot/oggvideotools/trunk/ any help (like patches, or additions) are very welcome. - Yorn Ogg Video Tools: contains some nice tools to create and handle ogg files (oggSlideshow, oggThumb, oggCut etc). It is written in C++.

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

j I think, I got the problem: When I re-encode both audio files with the same quality/bitrate, oggCat/oggJoin works as expected. The reason, that it does not work, is as follows: I had a lot of trouble concatenate the audio-files (as I was starting with video only). In many cases, the concatenation works even if the bitrate does not correspond (correct me if I am wrong). In some cases (ffmepg)

Hey Brian, I have had received a lot of complains about the concatenation of audio streams and I therefor decided to be very strict with the audio handling (the resulting file should always and ever be of good quality). That is the reason why sometimes the audio is reencoded even if it would fit. Are you and your friend using the same version of oggCat (as it was handeled less strict in the

> > I thought I fixed the problem with oggCut and ogg skeleton. What version of the Ogg Video Tools are you actually using? If you fixed the problem, I would be happy for a patch :-). > Well, the fix was more of a hack :) I was using oggvideotools 0.7a and the fix is removing the output from lines 189-191 in oggCut.cpp. The toString() method seems to trigger the segfault.

Hi everybody, I've had some time and so I added a slideshow creator with the Ken-Burns-Effect to the Ogg Video Tools. Feel free to visit the following page: http://www.server.streamnik.de:88/test.html It's best viewed with the Mozilla Firefox 3.1 Beta 2, but a Cortado Player is also available for the other browsers. The code is actually not publically available, as I would like to add

Hi Jan, all I am trying to generate a video introduction with a fade-in / fade-out effect. To do this with ffmpeg2theora only, I generated a list of PNG images: img001.png, img002.png... img299.png The ffmpeg2theora man page says: Encode a series of images: ffmpeg2theora frame%06d.png -o output.ogv That's exactly what I tried with the latest 0.24 release of ffmpeg2theora:

Hi everybody, I posted here about two years ago about the initial release. This is a release that fixes many bugs, and has enhancements that make it possible to support a multi-stream format, ALingA, which I will mention briefly later. It also supports a PCM format, Neuro, both as part of the multi-stream codec, and stand-alone. libogg++ is a C++ library implementing Ogg. It is designed to be

Hi J., We are using ffmpeg2theora to produce an introduction video from a series of images: ffmpeg2theora-0.26.linux32.bin images/img-%03d.png -o intro.ogv The video that we get is huge and horrible, with lots of blinking colors: http://free-electrons.com/issues/ffmpeg2theora-mar5-2010/intro.ogv Here's what we had in the past:

Hi, I'm trying to convert some quicktime files into Ogg/Theora using the Xiph QuickTime Components version 1.8. The end goal is to stream these files using apache httpd and the cortado applet (and hopefully the embedded players that will be in Firefox soon). Using iMovie DV on OS X 10.4.11 (intel) I'm able to export as an ogg movie, however the resultant file has problems with audio on
