Hi, I want to convert a function pointer call in the IR of MPlayer to a function call. For example, I have the following line: ... %10 = tail call i32 %7(%struct.demuxer* nonnull %0, i32 %1, i8* %2) #7, !dbg !863222 ... I want to set the target which is stored in %7 to a real function called "demux_lavf_control()" with the following definition: ... define internal i32

I am putting together an ogg mux/demux application which uses two logical streams. One is a vorbis stream, the other is some application specific data. This came together really quickly, following the ogg/vorbis documentation it took only a few hours to get it up and running. Just a small question... My application stream is currently running as a continuous stream but really I want it to be

Listening to the meeting on granule pos tonight/today it became clear that the issues everyone is concerned with for the most part don't affect my implementations and the issues i have pretty much don't affect anyone else... and in the cases where they overlap, the reasoning seems to be different. And since everyone else has had a lot more time to consider all these issues and i'm

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

Hello, I need to demux video files created with ffmpeg2theora 0.28+svn18147 I have ogminfo v1.5 and getting this error (ogminfo.c) OGG stream 1 is of an unknown type (bad header?) (ogminfo.c) OGG stream 2 is of an unknown type (bad header?) (ogminfo.c) (a1/serial 1092562206) Vorbis audio (channels 2 rate 48000) Is possible, that ogminfo is older then ffmpeg2theora ? Or what can be the reason?

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 !

I have been developing some directshow filters for ogg, and vorbis and speex... currently i have an ogg demux filter and a speex/vorbis decoding filter. In this pre-release only vorbis is operational... but the speex decoder is pretty much done... i jsut need to tweak the demux filter so that it can negotiate a speex connection with the other filter. Just though some people might find them useful

Hello, I would like to "piggy-back" other data in an Ogg/Vorbis I physical stream (i.e. file) in a manner that does not conflict with specifications and existing decoders/players/editors etc. As far as I can see, I have some possible choices: 1 - Chaining a logical bistream at the end. If this is the way to go, two questions arise to begin with: q1a - How to identify this stream in a

Friends, My name is Igor, I am new to this forum. I have a peculiar problem with my OGG/Speex implementation: I encode a short PCM stream in OGG/Speex, but the result can not be read by VLC and MediaInfo <http://mediaarea.net/nn/MediaInfo> reports that the file is too short (240ms). In reality the file contains about 2.7 sec worth of audio. Another interesting thing I noticed is that the

Hello all! i want to use Theora in a little video portal, because its free and open source and i want to contribute some code to get the Java Theora player (Cortado) more feature-rich. But now I'm stuck and hope that someone can point me into the right direction. I have videos stored in several formats (mostly H.264 or MPEG4) and use ffmpeg2theora to recode them on the fly. The recoded

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,

Dear members, since two weeks I am stuck, trying to demux a physical ogg stream (theora and vorbis) and play the audio part using vorbisfile. I hope that one of you can give me a hint or point me to additional documentation. I used ogg.h and vorbisfile.h. The way so far: - initializing an ogg_sync_state - inserting data to sync_state using ogg_sync_buffer - when whole page found

Hi, Is it expected that an Ogg logical bitstream might logically serve as the physical bitstream from which other logical bitstreams might be demuxed? I am not sure that I really see the point of doing this, but it would certainly be possible within the current spec. The trouble is that there are any number of ways to do the low-level muxing of several streams into one logical stream, with respect to paging and packetization. This makes it...

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....

Helo. I intend to use OGG audio in DivX movies because its excellent size/quality ratio. I was searching round many forums concering DivX conversion but didn't find satisfatory answer. So I send my question to you directly: 1,I am able to play movie with OGG audio on my PC but not on another one though I have installed last OGG Direct show filters.

Hi, I've seen several implementations of Ogg demuxing that use a zero granulepos to detect headers. However, I do not recall seeing this in the Ogg docs - is this an abuse that happens to work because Vorbis is timed by end granule, or is it a proper way to check ? Thanks

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
