Problems seeking
Locked
 
|
Hello,
i am trying to seek in a pipeline but it always seems to fail. I have tried it in every possible state NULL/READY/PAUSED/PLAYING but it never works. My pipeline setup is like that filesrc location=audio.ogg ! queue ! oggdemux ! vorbisparse ! vorbisdec ! audioconvert ! queue ! alsasink filesrc location=video.ogv ! queue ! oggdemux ! theoraparse ! theoradec ! queue ! dfbvideosink So the audio and video are in separate files. Playing stopping, pausing works fine. But i can't get seeking to work. I need seeking because i have 6 audio tracks in 6 files and need to beable to switch the track without stopping the video (or at least only pause it for a sec and than restart at the old position) I tried it like that 1) set pipeline PAUSED 2) get pipeline position 3) set pipeline NULL 4) set new location=audio.ogg 5) set pipeline PAUSED 6) seek to position got at (2) 7) set pipeline PLAYING I do wait for the ASYNC state changes, but the seek always returns FALSE, and the files starts playing at position 0. What am I doing wrong, cause i really can't find much in the net other than that seeking only works in paused/playing state. - Erwin ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

Do you need to set the pipeline in the NULL state after pausing it?

If I don't set the pipeline in NULL state i don't seem to be able to set a new location on the filesrc. - Erwin > > Regards, > Javi > > 2009/3/15 Erwin Rol <[hidden email]> > >> Hello, >> >> i am trying to seek in a pipeline but it always seems to fail.
