I would go more specific here: setOutputVideoCodec(...) and setOutputAudioCodec(...) So when mplayer supports vorbis in Avis/Ogm, you don't have to change API. > setProcessing(id, deint=0, aspect=0) > Sets wheter u want deinterlacing. 0 being none, 1 being the default > interlacer > or a string specifying a certain deinterlacer.

More > filters/operations can be added later) I would split it in various parts: setProcessingCrop(...) --> If not specified, don't crop. You can have also autodetect and: getProcessingCrop(...) --> Get recomended crop Maybe, in future, you can use mplayer's -vf rectangle to show user where it would crop. setProcessingAspect(...) getProcessingAspect(...) setDeinterlacer(...) getDeinterlacersList() > qeueIt(id, now) > Adds the job with id to the encoding qeue.

Maybe setNiceness() too! with setPriority() you can have EXCLUSIVE priority. That priority may set nice() (setNiceness()) to values lower than 0 and run alone. You could also have non-exclusive (SHARED?) priority, that priority would only allow process to be set to >= 0, and run together. Maybe one can specify how many process to run at once with some configuration value. So: setPriority( id, EXCLUSIVE | SHARED | ... ) getPriority( id ) setNiceness( id, nice = 0 ) getNiceness( id ) > > getProgress(id) > Returns 0 if the job has not been started yet, or a tuple (pass, > progress, > trem) if the job is being executed. pass being a name describing the > current > pass (fx Audio, Video pass 1 etc).

Or even better: removeJob(id) --> removes and clean up stopJob(id) --> just stop. Later process will resume from the lastest place it could. IE: IF you pause in the middle of encoding, but already rip, you're back to the begining of the encoding process again, when resume. With this you can reboot your machine, for example. restartJob(id) --> resume from stopJob() pauseJob(id) --> Just SIGSTOP process resumeJob(id) --> resume from pauseJob() (SIGCONT) > listJobs() > Returns a list of tuples, each tuple containg id and friendly name > (id, > friendlyname) > > What do u guys think?
