Hi John,
just to make sure I get this right, are you trying to build an advanced
version of Vantage Camera Ingest? Have fun then... ;-)
Let's go trough this step by step to find out if your approach makes sense:
Obviously you're trying to concat recordings from a DSLR.

Hi:
I filed a bug yesterday and Cigaes suggested my problem wasn't
really a bug and I should seek out help here, so I'm doing so. (Would it
be better for me to try to do this in html email with some markup instead
of plain text? Sorry there's so much ffmpeg/ffprobe output involved.)

Hi,
You should probably send to the list the command *with* the complete
console output when it fails, in addition to what you expect to happen.

Hi Nicolas,
> I suspect the difference might be related to the period time. FFmpeg
uses the lowest possible period time to allow low-latency uses, but it
makes for heavier CPU consumption.
I actually ran a test where I ran Arecord using FFMPEG's period_size and
buffer_size settings. Even when tho

Nicolas,
You're right and I understand your point. Apologies that I have top-posted
several times. I'll make sure to avoid it from now on.
This community is my last hope, as I've been stuck on this issue for over a

Replying to the troll, for once.
Carl Eugen has no formal authority on anybody on the list. But he, like
anybody else, has the author
Hi,
You're right. The 3Mbps speed is as expected.
However, this still doesn't explain why my FFmpeg command requires 95% of
my device's CPU to record raw audio audio, when the equivalent Arecord
command takes 5% of my CPU.
Again, here are my two commands:
arecord -v -r48000 -c2 -fS32_LE --perio
