The argument is in the form unit:amount. So --stop-at duration:10 for a 10 second encode, --stop-at pts:300300 to end when that timestamp is reached, or --stop-at frame:1000 to stop after reading 1000 frames. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@2286 b64f7644-9d1e-0410-96f1-a4d463321fa5

* Fix two problems that would cause HB to hang in the muxer whenever the input ↵van2008-07-301-23/+23
| | | | | | | | | | content's video finished before audio: - sync has to keep processing until all its input fifos report eof otherwise it won't send an eof on all its output fifos. - do_job has to wait for muxer to finish. Waiting for anything earlier in the pipeline (we were waiting for the video encoder) can cause other parts of the pipeline to get terminated early which will result in lost data & no eofs. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@1597 b64f7644-9d1e-0410-96f1-a4d463321fa5

* Adds a job->cfr boolean to indicate "encode this with a constant frame rate" ↵jbrjake2008-06-051-1/+1

| | | | | | | | | | | | end, and an deadlock with pcm audio. - since the SCR clock recovery is done in reader.c we can't currently skip audio frames during pass 1 or we miss clock changes signaled by those frames & end up dropping more video frames in pass 1 than pass 2. - since many modules buffer frames we can't tell if we're done just by looking for empty fifos. Send an empty buffer to mark end-of-stream all the way along the processing pipeline & use it to flush internally buffered data. - in a processing pipeline you're done when the end of the pipe says your done. add a thread status variable so we can tell when individual threads are finished then make do_job wait until the encoder thread is done so that we're sure all the frames have been processed and sent to the muxer. - since the muxer alternates between reading video & audio packets we have to have enough buffer in the audio pipeline to handle a video-frame's worth of audio packets (33ms). Since pcm packets are <1ms we need >60 slots in the audio fifos or we'll deadlock. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@1412 b64f7644-9d1e-0410-96f1-a4d463321fa5

* Minor chapter cleanups.van2008-04-041-0/+13
| | | | | | | | | | - put chapter number in buf rather than a 'new chapter' flag. - use that chapter number to index chapter text in muxers so a dropped chapter doesn't make all subsequent chapter labeling wrong. - get rid of most of the chapter logging & just output one line giving the chapter text, number, frame & time. - fix a bug in sync that could cause chapter marks to be lost. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@1377 b64f7644-9d1e-0410-96f1-a4d463321fa5

Get rid of fudge factors so we drop all such frames otherwise they screw up our a/v sync. - fix video timing 'off by one': since we look one frame ahead time has to actually advance on the next video frame. time that stays the same guarantees a one frame overlap which really messes up mp4 durations. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@1372 b64f7644-9d1e-0410-96f1-a4d463321fa5
