|

* file-name property
|

- supplying an already opened filedeskriptor would be more safe
|

- need to check what filesink does if the file exists and cannot be overwritten
|
||||
|
||||
* imagbin
|
||||
- we want async operation here (especialy for burst mode capture)
|
||||
- right now, its a bit fragile as we muck with locked_state
|
||||
- main problem is that the location for filesink can only be set in NULL/READY
|
||||
and we need to do that sync'ed with the dataflow. we can't use multifilesink
|
||||
as it does a file per pad_push
|
||||
- one problem of the current approach is that we can't have an image in e.g,
|
||||
postprocessing while anotherone is beeing saved
|
||||
- we could use a pool of imagebins:
|
||||
- configure one (set filename)
|
||||
- push_buffer
|
||||
- on eos, put it back to the pool
|
||||
- for this we need to check that we can have multiple instances of e.g.
|
||||
dsp jpeg encoders
