Additional information

Since upgrading to versions with the new GUI, I've seen an increase (but not always) where CCextractor instantly crashes with the above command line. In this particular case, comparing 0.88 (previous version I used) to 0.94 (current), in 0.88 it gets to about 62 minutes into the .vob file before it crashes. In 0.94, it crashes instantly when I click to process or start via cmd line. Interestingly, if I first re-mux this .vob file to .mpg and run the resulting new file through ccextractor, it is able to extract the closed captions fine without crashing. I also tried re-muxing to .mkv format, but got a differing error (no crash, just unable to read mkv for whichever reason)

@canihavesomecoffee Did you get the files? If not, let's close the ticket.

@cfsmp3 I believe I had sent them over back when, but can again if need be.

Thanks.

@r0ckingit yes please - we're catching up with this stuff now.

I will get back to you soon with a new sample file. I figure there is no rush given the time span this far, but wanted to acknowledge in the mean time. I’d love a fix!On Dec 20, 2025, at 1:35 PM, Carlos Fernandez Sanz ***@***.***> wrote:cfsmp3 left a comment (CCExtractor/ccextractor#1414) @r0ckingit yes please - we're catching up with this stuff now. —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you were mentioned.Message ID: ***@***.***>
