search for: oggz_seek

I have a 1.1G Ogg file with vorbis and theora. oggz_seek_units() takes 14 seconds to find a position in the file towards the end. Now, the function guess() in oggz_seek() guesses a position at about 1.5G and then slowly searches back until it finds the end of the file (continously seeking beyond the end of the file and then calling read which returns 0...

...d it means that seeks into regions which are buffered are almost instantaneous - which is a big improvement! I had to change liboggz, so I wonder if you guys would accept the change in your repository? My patch to liboggz is below.

I need to be exposed to a way of seeking theora streams. I have repeatedly found the same question asked on a different forums but could not find an answer. I'm working on a game and started integrating video with theora, the sound works just fine with ogg/vorbis(i find it easy to seek using ov_raw_seek for audio files). Could someone please point me to some example/code of how can i seek with

...pen a Ogg Speex-encoded audio file with oggz_open("MyFile.spx", OGGZ_READ | OGGZ_AUTO); - I have a loop of invocations of oggz_read() that triggers in the due time the page and packet callbacks defined by me. - But when I randomly do seeking by means of ogg_int64_t rseek = oggz_seek_units(pOGGZ, posMsecs, SEEK_SET); I get erratic results: Many times rseek does not match posMsecs. The first page callback after the seek invocation refers to a page that is sometimes previous and sometimes after the page that contains posMsecs. What rules ar...
