search for: ogg_stream_flush

Hi, While building an ogg-vorbis stream encoder, I encountered some problems with silence in the audiostream. The bitrate drops to almost zero, and pages going out less then ones a minute what makes the stream to stop / buffer. In earlier postings I read that I shout use ogg_stream_flush as an alternative to ogg_stream_pageout, in case of silence. My question is this; Is there any reason for not using ogg_stream_flush all the time. So what are the advantages of ogg_stream_pageout?

I was wondering. When doing ogg only encoding, how do you mark end of stream? I am setting ogg_packet.e_o_s and then submitting it via ogg_stream_packetin() and then, because its the last potential page ogg_stream_flush()ing it. But when I walk through the file, EOS is not set on that logical bitstream. I have been using oggenc.c/encoder.c and oggdec.c/decoder.c for examples, but because the packet assembly is done down in the vorbis stuff, I havent yet seen how this is handled normally. Any help would be greatly...

Hi there, for a streaming application developed for a project at the Society for Arts and Technology Montreal, Canada, we would need to know the exact delay of our ogg/vorbis streams. It seems there are several factors that make up the total delay I get. Is there a way to find out how large the delay introduced by the encoder and decoder is? Or in other words, how many unprocessed samples

...ogginfo seekable.ogg Processing file "seekable.ogg"... New logical stream (#1, serial: 00003039): type unknown Warning: EOS not set on stream 1 I have looked into this and suspect that the FLAC__stream_encoder_finish() function needs to finish off the stream using a call to ogg_stream_flush() instead of the standard function ogg_stream_pageout(). Josh (or anyone), I'd appreciate it if you could take a look at this.

In the Ogg code, I believe that there are two things that must be satisfied to correctly write an end of stream: - packet.e_o_s must be true - Need to call ogg_stream_flush() instead of instead of ogg_stream_pageout() I haven't tested it, but I don't think just setting packet.e_o_s is sufficient to close the stream. The forced ogg_stream_flush() is required. Maybe these two actions can be carried out in the function FLAC__ogg_encoder_aspect_finish() wh...

...l no more ogg_packets needs to be added? Or do I need to call ogg_stream_pageout after every ogg_stream_packetin? Iaw may I delay calling ogg_stream_pageout until there are no more packets to be added? 2.) I assume I have call ogg_stream_pageout until no more pages can be created and then call ogg_stream_flush if there are still bits left to be 'paged'? 3.) Do I need to manually set the e_o_s of the last packet added? 4.) may I call ogg_stream_init again on a already used ogg_stream_state struct to reuse it? 5.) Is it possible to start decoding a ogg_stream which has not yet been fully cons...

I need it to be able to take a stream of PCM data and encode it. Right now it works if I am recording from a source (i.e. microphone or with "what you hear") but when I try to use another API (Team Speak) to capture the PCM data it doesn't seem to be encoding correctly. (I know the PCM data is correct. I am able to use it to create a wav file.) I'm also having a problem with

When using ogg_stream_pageout(), I'm making sure that all the remaining pages are flushed at the end;...

Hi, I have recently implemented encoding/decoding to/from OggVorbis in my app, with the code being based upon the Libvorbisenc sample code supplied with the SDK. It all works very well indeed (encoding from a PCM file, then playback), except that no matter the length of the source PCM file, the last (approx) 4 seconds of audio is always missing from the Ogg file. I am trying to find some
