Video files corrupted after post processing extraction

Post by westsidesuburbanite »

I have sabnzbd installed and I'm running it with the post processing to extract files itself. I noticed a LOT of video files that it extracted were corrupt.

When I go to play them they will have a point where they just stop playing sometimes, and VLC will just freeze up. I confirmed this is sabnzbd causing this because if I extract them manually again they will play correctly.

I'm wondering if this is an issue because the download folder and completed folder are on different drives? Or if it's because it's trying to do it while downloading (1Gig DL speed)? Or if there's another issue that could be causing this.

Thanks!

On top of Sander's questions (things we need to know), did you maybe disable "Post-process only verified jobs" in Config > Switches?

I'm on Windows. Version is the latest release however I believe it's done it on previous ones too. The drives are 14TB Seagate Exos, but the temp drive is a 10TB Ironwolf. The size of the video file extracted automatically AND the size of the manual one are both the same exact size. I have post-process only verified jobs on. Even if it was disabled though, wouldn't it make sense that if I can manually extract them that the download has no errors since the original rar files are able to extract without error?

I'm not 100% sure why the video doesn't play right. The file size is the same. It will usually play some of the video but just freeze at some point. It's not happening to all of the downloads, just some which is why I thought maybe because the download speed is so fast that it has issues while extracting due to disk write or that moving the files from one drive to another might be why.

Same size? OK, then let's compare the checksum of the automatic and the manually unpacked video files: are they the same, or different?

On my Windows, in Explorer, right-click a file offers "CRC SHA" -> SHA-256. Do you have that too? If so, get the SHA256 on each file.

If not, open a CMD box, and calculate like this:

Code: Select all

C:\....    CertUtil -hashfile ubuntu-20.04.2.0-desktop-amd64.iso  MD5
MD5 hash of ubuntu-20.04.2.0-desktop-amd64.iso:
2b0bfcb7e9e95c8eadb14a6fb59efae8
CertUtil: -hashfile command completed successfully.

You are correct. The SHA hash shows differently for both files. I verified that one file will play completely and that the auto extracted one does not, and they don't match hashes. So, what could be the cause of this?

A few things to do:

- check sabnzbd.log if you see any errors or Tracebacks in there.
- redownload with SAB, and check what result you get
- share the .NZB (on pastebin?) so that I can download and check.
