jit.movie~ is only supported by the viddll engine.

if you want to use hap engine, you must use jit.movie.

if you have a hap file that is crashing in either jit.movie @engine hap or jit.movie~ you can send me the file and i'll try and see why it's crashing (robr at cycling74.com)

Thank you for your reply. At your prompt, I did more tests on two computers, hoping to make the problem clear. This is my patch.

I cut my 4k（4096*2048 30fps） video file for a 2 second clip for testing. I tested it on vdmx and it works perfectly. How to give you my video file. Thanks!

are you running in 32 bit mode? definitely recommend 64 bit for viddll engine video. you can increase your cache size which may help the crashing in jit.movie~, by setting @cache_size 2 in each of your jit.movie~ objects (for 2 GBs, adjust to your needs and RAM specs).

the hap engine will always play hap files better, so If you need that performance then simply strip the audio file out and play it with sfplay~, syncing the video playback to the audio. if you need help with that i can send you a patch.

I don't know why my program is running by default with 32 bits. Thank you for your reminder. I switched back to 64 bit now. I think your patch can help me a lot. I haven't used ''splay~'' before for this, I need to change the playback speed, I am worried that this will cause synchronization problems, so I always building the program on jit.movie~.

By the way, I found that rate $1 does not work smoothly on jit.movie~(no problem on jit.movie), and the speed is limited to a few fixed values. Is this a bug?

here's a basic patch showing how to sync a jit.movie with an sfplay~ if both have the same duration.

it will send a seek message (time_secs in this case) to the jit.movie to re-sync. an alternative approach is to use the rate message to speed up or slow down until it's back in sync.

if you want to change the rate dynamically, send the same value to jit.movie @rate attribute, and sfplay~ @speed attribute.
