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 test samples...

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 that helps....

...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 version before)? Technically the code is completely the same on both systems. The only difference might be between 32 to 64 systems. -yorn BTW: you can also use oggSilence to produce a duration of silence. ----- Urspr?ngliche Nachricht ----- Von: Brian R...

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 the number of seconds of audio in the resulting file, taking a couple minutes, which is how long it would take to encode the audio in que...

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) the...

...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 tried to use oggCat: oggCat final.ogv intro.ogv video.ogv Unfortunately, this doesn't work well because my intro video has no sound track to be concatenated with the one in the real video. As a consequence, the concatenated video only has a video track. It tried to add a silent track to my introduction video (sa...

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 practice... i always get cat files that have some errors, so should the people i will encourage to use oggcat... also it is a little scaring to use comma...

...t to mozilla), i would love to help for that as you offered in your previous mail but i am just new into oggvideotools and not a tech person, so maybe i can help for video tutorials when i have more experince... but i am planning to write a very simple dummy's tutorial for the students just for oggcat on windows to concatenate some videos we are working on... anyway, oggcat works great for me on windows! but there is one issue i should let you know about the Skeleton... oggcat works totally ok on windows for the ogg files created with ffmpeg2theora 0.18... it also works for ogv files created...

...files to ogg theora but it cannot join/ concatenate / merge the several input files to one ogg file. is there a way (add a simple command on the command line of the GUI) to make it join the input files... our input files will be all ogg theora with same spesifications except for lenght and i think oggcat command does this on linux but we need a GUI for windows to do that. simple theora encoder does it for mac, as i read also http://commons.wikimedia.org/wiki/Help:Converting_video so, 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 i...

...l you about the file when you've merged it (without skeleton)? It may say that there are two logical video bitstreams, because they've come from different files. So, two skeletons may actually be correct. I hear that ffmpeg has a a concat feature. Not sure how it does it. There's also OggCat (http://en.flossmanuals.net/ogg-theora/command-line-editing/cat-files/). However, you have to make sure that the video is encoded with the same parameters (same resolution, audio encoding parameters). Multiple skeletons are actually valid, so you should be able to deal with it! HTH. Cheers, Silv...

Hi All I'm currently trying to put together an ogg file with two theora streams, a handful of audio streams (probably mixed vorbis and opus), and a Skeleton stream that describes their relationships to each other. I had hoped to be able to use the oggz suite of tools, but I can't seem to get that to work. To generate my theora files, I'm using ffmpeg2theora, which will happily
