similar to: oggcat or other ways to combine theora videos (with or without re-encoding)?

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

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

hi all, i have written a detailed explanation below bu in short, we need a simple free gui for windows to join several ogg files end by end to make one ogg file out of it for an art project. you can see more explanation below... i am working on an art projects with some art students called "readymade dictionary of the author: a copyleft crowdsourcing free/open source project" where

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

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)

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

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

Hi, folks. I'm trying to prepend an OGG file with a given amount of silence. The solution that another developer and I are working with is to generate an audio file of a given duration of silence, convert that to OGG and use oggCat to try to append them. This does work, however I'm seeing that in Windows, oggCat is seems to be re-encoding the audio (it counts from 0 to what I assume is

I mentioned it in the #theora channel a few days ago but here it is with a more permanent url: http://www.firefogg.org/make/advanced.html & http://www.firefogg.org/make/ These will be simple links you can send people so that they can encode source footage to a local ogg video file with the latest and greatest ogg encoders (presently thusnelda and vorbis). Updates to thusnelda and

this sample is very blocky, the older version seems to do much better and less blocky video. i'm not sure if my 1.9ghz 1 gb ram is the problem here or the encoder has hicups on this new libtheora 1.1 20090806 (Thusnelda). please advice how to fix this or should i use the older version. this encode was 2 pass with horrible output. http://www.megaupload.com/?d=NDGY0EAL General ID

Hi, do you know the author of the ffmpeg2theora project? Because his domain name, http://v2v.cc/, which hosts the project, expired on 2010-07-16, and pending renewal or deletion. The contact email address listed on the page also use the v2v.cc domain, so I cannot contact him. Please notify him ASAP if you know his other address! In the meantime, how can I install ffmpeg2theora 0.27 on Ubuntu? I

Hey, everyone. I'm sure this thread will generate some email! Some people are working on a super-easy to use converter for people to be able to convert videos to Theora for the upcoming Get Video on Wikipedia push: http://videoonwikipedia.org/ (Note that this isn't being pushed yet, and is pre-launch quality!) For the converter one thing we'd like to be able to provide is a set

Unfortunately, one of the applications we want to use this with has declared not supporting chained OGG streams, so we cannot do a simple file concatenation. So far, yorn has been helping me troubleshoot. It looks like the previous release (0.80) was less picky about the input files, but I haven't been able to try using oggSilence because when I specify a bitrate at or above 128Kbps, the

Thanks a lot for the new encoder_example and the two pass encoding. I was not yet able to compare the gain of it against my previously encoded video (HD content takes a lot of time to encode). Why it can not be used with -v ? Could it be possible in the future ? I had better result with -v than with -V before. Congratulations again. -------------- next part -------------- An HTML attachment was

Hello, I hope this is not an inappropriate list for this. This is the list suggested by http://www.xiph.org/quicktime/ I use Linux exclusively at the moment and do not plan on buying a Mac, but I am working on a CMS including html5 media support. Patent licensing costs forbid decoding proprietary video formats on the server for transcode into Ogg Theora so I am looking for a way that non

ffmpeg2theora nightly builds found at http://firefogg.org/nightly/ still uses Thusnelda. Where can I get a Ptalarbvorm version for Windows? Regards

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

Hi All, Firefox 3.1 will be released in a couple of months and I still feel we need a strong knowledge base to leverage a widespread use of Theora. While working on the Firefox in Motion video I've been looking for some kind of comprehensive documentation, but the best I could get was answers of the community here (thank you again). Theora will not become a standard if people have to err and
