[Mjpeg-users] Buz Performance Update

[Aaron N. <ane...@an...>]

Preliminary data, but I just wanted to post that -d 1 with the Buz,
everything else otherwise the same EXCEPT I save to a 100Mbs network
connected drive does NOT drop any frames, at least not with the 2 minute
capture test I did:

LAV_VIDEO_DEV=/dev/video1  lavrec -d 1 --input N --format a
--synchronization 2 --audio-bitsize 16 --audio-bitrate 48000 --stereo
--audio-volume -1 --time 120  --file-flush 0 --quality 65 --batch
"QuickTest.avi"

Recording time  :  0.02.23:22
Lost frames     : 000
A/V sync ins/del: 048/000
Audio errors    : 000


Still getting a lot of ins frames though,.. but it looks like my 3Ware
IDE RAID card is not quite as high throughput as I thought it was. The
network connected hard drive is a 7200 RPM Seagate Barracuda, connected to
the host via a firewire interface.

More testing needed now with this new data, and a possible ditching of the
3Ware (maybe even going firewire locally!!).
