Wirecast crash -> corrupt files
on Apr 27, 2009 at 10:19:12 pm

Hi, Craig

I'm Benoît Joossen, founder of aeroquartet.com
One of my business is to repair damaged video files.

I've noticed recently an increase in the quantity of Wirecast corrupt files that are coming to me.
While I can repair them in most cases, it's sad to see so many people in deep trouble after losing an important recording.

Just wanted to know if this is perceived as a very common problem by you guys.
I will contact Telestream people to see what can be done. Do you have a contact in customer support or in the development team?

Regards, BJ

Benoît,

Can you tell me what you're seeing in the corrupt files?
There were bugs in 3.5 but it was quickly replaced with 3.5.1

Are the files from Mac or Windows version?
If Windows is it XP or Vista?
What codec are the files?
Are you sure they're on 3.5.1?

I'm seeing an issue in which files aren't getting there extension on the Windows version but adding it by hand works. I'm not sure how common that issue is though. I've never lost a file myself.

You can use the support link on their website to contact them.

Craig,

Basically I see two types of corrupt files:
1. Application crashed/hangs/runs out of disk space, before movie can be closed. As a result, the movie index (header, tail) is not written, and the file refuses to open.
2. Recording ended correctly, but movie doesn't have video.

The cases below come from my repair customers, who do not usually indicate the versions they are using.
All are Mac users.

case [09039], January 2009
MacPro running current OS and latest quicktime
Wirecast using Quicktime
The file was corrupted by the HDD running out of space unexpectedly, and then the capture froze.
Media: DV PAL and AAC audio.
Repair Technique: Reindexing

case [09083], March 2009
Wirecast 640x480 H.264 video, MP4 audio
Application Crashed
Repair Technique: Reindexing

case [09111], March 2009
Quicktime H264 1500kbps 480X360 25FPS
After recording the QT file video track was black. File opens w/ QuickTime, audio is here, but no video.
Repair Technique: Inspection of structure shows that all is in place except video stsd (sample description). We add this atom and file is OK.

case [09136], April 2009
Wirecast crasched twice and 2 recorded files where damaged, the other one is 113 mb.
H264 480x360, audio AAC 32000Hz.
Repair Technique: Reindexing

I just had about a 50% failure rate with Quicktime recordings on a PC based Wirecast system today. Before I send them off to Benoit to get fixed, are there any other solutions I might try first?

The only issue I've seen around Quicktime recording on Windows is quality based. There's nothing I can think of that would cause that kind of failure rate offhand.
Make sure you're using Wirecast 4.2.6.
Don't record to the system drive.
