[libdv-dev] Continuous "audio block/sample failure" with JVC DV camera

[Nathan K. <nat...@ya...>]

Hello,

Whenever I dump DV from my JVC camera I get continuous lines like:

    asf 00:00:00.00 2000-00-00 00:00:00 70 b7 08 12 2/48
    ...above repeated 30 times...
    # audio block/sample failure for 0 blocks, 60 samples of 1280

The resulting audio stream sounds odd, with little breaks in it. (As one 
might expect if 60 out of every 1280 audio samples were bad.)

Details:
--------
Camera:     JVC GR-DVL28 (PAL)
OS:         Mandrake 10, 2.6 kernel
Libdv:      libdv 0.102  (libdv4-0.102-1mdk.rpm package)
Other libs: libraw1394_5-0.9.0-4mdk, libdc1394_0-0.9.2-1mdk,
             libavc1394_0-0.4.1-4mdk

This problem occurs consistently and immediately with dvgrab 1.5/1.6 and 
Cinelerra 1.2.1.

Running the command
   dvgrab testvideo
immediately shows the "audio failure" output lines listed above.

I searched google and this list's archives, and the only reference to 
this I could find was
https://core.fluendo.com/trac/cgi-bin/trac.cgi/ticket/67
which suggests there is a problem with JVC cameras and libdv.

So my questions: Has anyone else experienced this?  Is this a known 
problem? Is there any workaround/fix?  Is there any more info I should 
supply?

I'd be grateful for any suggestions on how to debug this further.

Thanks to the developers (Buck and Dan especially) for making this lib!

Best Regards,

-Nathan
