You should not have added a queue in your context at all, you should have used the one already present using the API in filters.h. As far as I see there is only API to get the first frame in the fifo, and to check if there is at least one frame in the fifo. What I need is to get the frame->pts of the frames (first and last) in the fifo. Paul suggested to #define FF_INTERNAL_FIELDS, this way I can access inlink->fifo directly, and I can use the framequeue.h functions on the inlink fifo. Is this what you are suggesting?

Thank you.
what about to create a new parameter for the filters: relcue/arelcue ?
relcue would be a relative value to current timestamp. This way the
shell variable will be unneeded.
The shell variable is needed to be able to provide a common start
timestamp to all the processes. If relative timestamp is used, that kind
of defeats the purpose of synchronization, because different processes
will have different delays in opening their inputs, which means variable
delay in initalizing their filters, so the start time for passing data
will not be common among processes.
usage of cue and relcue would be mutally esclusive parameters.
Obviously it is possible, can be added later if somebody finds a valid use
case for it :)

Marton
