problem on freescale gstreamer plugin

[Volter Yen]

Hi all,

    I am working on freescale i.mx27 for mutltimedia application developing,according to the requirement I should construct a decode pipe and an encode pipe line at the same time.    It seem to impossibe that using the freescale's decode and encode plugin at the same time. because they need to open the '/dev/vpu'  when initialize the plugins for both decode plugin and decode plugin,  but it is not permitted to do so, then the systemIOinit() could not be finished, that is only one pipe line is allowed. 

     has anyone meet  the similiar problem and how to work it out? please give me some hint on it.  thank you!

You are probably asking the wrong mailinglist: you are plugins by
Freescale that are not availble in GStreamer.

[mleeman@bane gst-git]$ gst-inspect encode
No such element or plugin 'encode'
[mleeman@bane gst-git]$ gst-inspect decode
No such element or plugin 'decode'

[mleeman@bane 20090811]$ find . -name '*.[ch]' |xargs grep systemIOinit
[mleeman@bane 20090811]$ find . -name '*.[ch]' |xargs grep vpu

Both show nothing.

You seem to be confusing GStreamer with custom hardware drivers from
what I make out from your post.

Hi marc,

   I know this mailist is mainly focused on the opensource gstreamer items, but I think there are still many people on ti or freescale's hardware platform using partly the gstreamer opensource framework. and then they would be in this maillist too. when they notice this problem, they expirenced engineer would give me some hint on this issue.  Anyway, thank you for the reply.
