What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
It is the latest version ( i just downloaded it)
Can you repeat the problem? If so, what are the steps?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)
yes the problem is recxreatable.
here is a qiuck peice of footage
also i am really sorry if this isnt a bug. im just stupid
What are the properties of your source file? Codec, resolution, duration? If you speed something up by 23x, then the duration will be 1/23 of the time. I wonder if that is making the clip too short.
no the clip is over 30 minutes long. so it shouldnt be to short. the source file is always in mp4. and the codec is the default. the resolution is 1080p. (i edit for someone)
this also occurs with clips that are hours long, and trust me my computer can handle that sutff but shotcut just dies. I record in 2k and with the same length of footage and even mp4, just a different software, and it still occurs.
this is very strange. I am running the exact same thing but every time i try to play the footage that is just one bit over x23, it crashes
we also have the same form of drive setup
There was a fix in this area for version 21.02 when enabling Image Sequence in Properties, and that fix was applied to the other types of Properties (e.g. video clip). I think that explains why you did not reproduced in 21.01 but not 21.02.
i downloaded 21.02.15
the problem continued. I am completely unsure why this is happening. At one point i got error messages due to some of shotcuts files mysteriously disapearing, but just redownloading it, got rid of those messages. although the crash continued, no matter the length of footage
I am able to reproduce this with 21.02.27 in Windows, But I not able to reproduce it in Linux.
I have only experienced the crash when changing the speed on a clip on the timeline. If I change the speed of a clip in the source player, it has not crashed for me. But, if I drag the changed clip from the source player to the timeline then Shotcut will crash.
When using a debug build (as in the SDK) Dr. Mingw generates a shotcut.rpt file, which contains a backtrace, alongside shotcut.exe. You can also run Windows debug build in gdb, but that is painfully slow.
Also, immediately before the crash, the console has this message:
[Info ] [filter swresample] 2(stereo) f32le 1200000Hz -> 1(mono) f32le 48000Hz
[Info ] [filter swresample] 1(mono) f32le 1200000Hz -> 1(mono) f32le 48000Hz
[Error ] [filter swresample] swr_convert() failed. Alloc: 800 In: 800 Out: 0
In that case the resample filter leaves the audio buffer unchanged and returns an error code because the resampler needs more samples.
Perhaps the mix transition does not like that error code or there is something wrong with the returned buffer.
It seems like this wouldn’t be too hard to track down. But I will put it on the back of my TODO list because I do not currently have a working Windows development environment.
