Problem using CCExtractor 0.55 on one certain file ...

[epstewart]

Hi,

I'm trying to use CCExtractor 0.55 on a certain file which contains an HD recording of "Bruce Springsteen & the E Street Band - Live in Barcelona," recorded by my TiVo and downloaded to my iMac. I've used CCExtractor a lot on other files that have been created in the same way, but this is the only one so far that has come from the Palladia HD channel. When I use the command line

iMac:~ eric$ /Users/eric/Desktop/ccextractor /Volumes/Hitachi\ 2TB\ Drive/Music/Bruce\ Springsteen\ \&\ the\ E\ Street\ Band\ -\ Live\ in\ Barcelona/Bruce\ Springsteen\ and\ the\ E\ Street\ Band\ Live\ in\ Barcelona\ \(06_16_2010\).mpg

I see oodles of complaints like this:

Warning: Reference clock has changed abruptly (33 seconds), attempting to synchronize
Last sync PTS value: 3750097
Current PTS value: 6765109
Change did not occur on first frame - probably a broken GOP

and the output .srt file has wildly inappropriate subtitle timings ... though all the subtitles appear to be there, in the right sequence.

If I add the -gt option ("Use GOP for timing instead of PTS") to the ccextractor command, virtually all the error messages disappear, but the subtitle clock in the output file seems to have been reset to zero every few seconds. Maybe that's the source of the "reference clock" errors in the error messages for the first ccextractor call.

Adding the -fp option to "fix padding" is no help.

The actual .mpg file seems to play fine, and to show its closed captions fine, when I look at it on my iMac in MPlayer OSX Extended, so clearly there are captions in the file, and they are capable of being displayed correctly and with proper timing.

Can anyone tell me what to do to get ccextractor to extract the captions in usable form? Or, alternatively, how to correct the incorrect timings in my ccextractor output file? Thanks ...

Have you tried running the file through VideoRedo's Quickstream Fix first and then attempting to extract the captions?

OK, great! VideoReDo's Quick Stream Fix was just what the doctor ordered, and once I did that, CCExtractor was at last able to extract the captions just fine! Thank you very much for the idea ...
