vrecord crash when capturing PAL

[kieranjol]

Using 0.7.9, vrecord, specifically ffplay crashes once we start capturing PAL from a Blackmagic ultra studio 4k. It captures a frame and that's it. I'm attaching the video file and all the logs: https://www.dropbox.com/s/kx75aaa2vzpmvq3/Archive.zip?dl=0

Here's possibly a key error from the ffmpeg log: [v210 @ 0x7fdec300f200] packet too small Error while decoding stream #0:0: Invalid data found when processing input [output stream 0:0 @ 0x7fdec17044c0] EOF on sink link output stream 0:0:default. [output stream 0:2 @ 0x7fdec17034c0] EOF on sink link output stream 0:2:default. [output stream 0:1 @ 0x7fdec1703d40] EOF on sink link output stream 0:1:default. [output stream 1:0 @ 0x7fdec3800a40] EOF on sink link output stream 1:0:default. No more output streams to write to, finishing.

Dave, any idea what the error might be?

@kieranjol what does it say when you bmdcapture -h

Bern testers have been capturing PAL and haven't had any crashes as of yet.

[kieranjol]

Thanks @jfarbowitz . It's surely something on our end. We'll need to investigate more. It doesn't help that it's not a VTR that we're testing with. Our only blackmagic card is hooked up to a standard def PAL 8mm/16mm telecine machine. It has captured just fine with FCP/Avid/Media Express, but we probably need to investigate our settings when hooking it up to vrecord. Those capture tools all have shortcomings that I'm hoping can be alleviated with vrecord.

On a side note, it'd be great if you could pass along my email address along to the Bern people, or if they're comfortable with me getting in touch first. I'd be interested to hear how they've been getting on with PAL vrecord. kieran[dot]o[dot]leary [attt] gmail[dot]com

I was able to do some testing today and all was well. Maybe the mac needed a reboot after installation or something? You have created some truly wonderful software. I hope that we can make use of it at the one workstation that has a blackmagic card. All those logs & framemd5s are just a thing of beauty. You're all amazing!!!
