similar to: option to push "duplicate frame" packet to oggmux

Hallo all, I currently hacking on cheese an got problem with variable framerate produced by webcams (2-30fps). There is no problem to encode it with theora, but problem to mux it in ogg. Or at least to play produced file. There is no problem tu mux it in to matroska. My question is: should actually ogg support timestamps, also variable framerate? If yes: it seems to be some where broken. Here

Hallo oggs, i googled it but still can't find any answer: how can i set default audio track? I transcode my dvds to ogg, i use gst-launch for it: gst-launch filesrc location=stream.dump ! mpegpsdemux name=demux \ oggmux name=mux ! filesink location=out.ogg \ demux.audio_80 ! a52dec mode=2 ! audioconvert ! audioresample ! audio/x-raw-float,rate=44100,channels=2 ! audiorate ! \ taginject

Typically video players will play back the last audio track in a Ogg Theora file, because it is the last one that they see. There is no way to specify which is the "default" audio track and it would not make sense anyway. If you are a German speaker, your "default" would be the German audio track - if you are a native English speaker, it would be the English audio track. So,

Hey all! I'm sure you've all been missing my webcam stream, so I decided to start it up again (also, I wanted to do it for my family overseas). However, this time, I'm doing things a little bit differently. For starters, the encoder is the current (as of about an hour ago) ptalarbvorm branch which is destined to become libtheora 1.2. Another difference is that I'm using

Thanks for responding! Yes, I'm using gstreamer and I'm simply broadcasting the test video source. The only difference between the mountpoints is the mount-option to the shout2send-sink, test.ogg and test2.ogg.

By browsing on the mailing list I learned that its possible to generate .h263 asterisk friendly files with gstreamer. The script below it's supposed to do just that, however I get error when trying it out locally. gst-launch filesrc location=AstriDevCon_Europe_2006.mov ! qtdemux name=demux ! ffdec_h263 ! videoscale ! video/x-raw-yuv,width=352,height=288 ! ffenc_h263 rtp-payload-size=512 !

Hello, I have in the past few days played a bit with libogg. My goal is to learn enough of it to try wrapping current tarkin codecs into an ogg file, with vorbis sound eventually. I did work on a small program which allows you to easyly (de)multiplex Ogg files in a way which seems to conform to the docs. You can do things like: oggmux in1.ogg in2.ogg in3.ogg - mux3.ogg oggmux mux3.ogg -

Well, actually most OGM files do have a subtitle track, often in multiple langauges. Also, re 2. Keyframe seeking in OGM is generally a bit rough because ogm files can contain almost any codec as the video track, usually xvid or divx. re 1. As a general rule you shouldn't be trying to make any more ogm files :) So chances are the ogg muxer is not accepting the connection, because it

Hi all, I am trying to test DirectShow PushSource example from the SDK with Theora encoder and Ogg muxer (DirectShow filters of course) by using GraphEdit tool. My goal is capturing the screen as video by taking snaphot bitmaps continuosly (what PushSource eaxmple does) and giving them to the Theora encoder through the DS pipeline (next goal is transmitting this video **). My DirectShow graph is

Hi All! I have some troubles with OGG and GStreamer: 1) When I parsing ogg file with ogmdemux element, I recieve (in "pad-added" signal callback) video pad as "application/x-ogm-video", but not as "video/something". And that why I can't link It to the oggmux element and write new OGG file :( 2) I'am using "playbin" to play media file, but It

Hi all, This may sound like a weird problem, but I am trying to create a DirectShow graph (using the Theora DirectShow filters from http://www.illiminable.com/ogg/) where I have a video source, which is connected to the Theora encoder, which is then connected to a Theora decoder. The problem is that this doesn't seem to work, those filters refuse to connect to each other. Now obviously
