search for: ogg_page_granulepo

I have the following problem. Be an encoder application (station) and a decoder application (receiver). If I feed the vorbis encoder with 'n' pcm samples in the station I want to know how many pcm samples will be decoded in the receiver if I feed the decoder with the encoded output. The ogg_page_granulepos is right for the purpose? I read the documentation about the ogg_page_granulepos function. There is the following: "Returns the exact granular position of the packet data contained at the end of this page. This is useful for tracking location when seeking or decoding. For example, in audio c...

...does just that, but it never seeks exactly where it should. For example if I use oggz_seek_units(oggz, 18450, SEEK_SET) result it's 16386 and there is a delay between the playback and the moment where it should start. Only when I seek to position 0 I get the desired result. I've also used ogg_page_granulepos for seeking but it seems more difficult to use. I use something like this: do { while (ogg_sync_pageout(&oy, &og) != 1) { data = ogg_sync_buffer(&oy, 512); readbytes = fread(data, 1, 512, spxfile); ogg_sync_wrote(&oy, rea...

Hello Conrad, I'm trying to seek the way you told but I'm facing a problem. ogg_page_packets returns 164 and following code returns 189. Shouldn't it be the same, what does that means ? int res; while (true) { res = ogg_stream_packetout(&os, &op); if (res == 1) nPackets++; if (res == -1)

...s is an array bounds guard. I guess it's defensive programming vs warning.

I'm adding some final features to my CD Ripper and Encoder before the full, version 1 release. As part of that release, the program will offer the ability to play (for review purposes) both WAV and OGG files. I have both the decoder and playback code working but I have one final issue to resolve: finding the play time for the Vorbis bitstream that is being played back. I used the

Hi, when I encode some files with the current CVS I get the following error with ogginfo: [...] New logical stream (#1, serial: 476aea05): type vorbis Warning: Vorbis stream 1 does not have headers correctly framed. Terminal header page contains additional packets or has non-zero granulepos Vorbis headers parsed for stream 1, information follows... Version: 0 Vendor: Xiph.Org libVorbis I 20020713

...9 fps. Since Theora is fed with a framerate which isn't precise the time of each frame when I play it in VLC doesn't match the exact time of when the frame occurred. So basically I wonder how can I sync a video frame to a clock using Theora and Ogg? I tried looking at?th_granule_time() and?ogg_page_granulepos() but they seem to be concerned with the frame number and not time of the frame. Thanks for a great video codec! Regards Bjoern

Hello, All. First, I want to thank Ian Malone and Ralph Giles, thanks for your kind replies. But I still have problems about seek. As you suggested, I could use ov_open_callbacks() to supply my own read/write/seek functions. So, can you give me an example? I?m sorry for my ignorance, because I haven?t used callbacks before. I analyzed the vorbisfile.c in Tremor, and I think I

Hi Seeing as other people are posting streams to test, the system I have been developing has an Ogg/Vorbis/Theora stream that you can watch. I would appreciate any feedback to what players can play it and which players have problems. (I am using Icecast as the streaming server) So far I have found VideoLan plays the stream very well. MPlayer was ok, but wasn't as good at buffering.
