@wim: that was exactly what I was looking for, only for linux :-) It finally came back, haven't been doing this for some time. One test would be
tcprobe -i file.avi
The result with my AVI is:
$> tcprobe -i MVI_0566.AVI
[tcprobe] RIFF data, AVI video
[avilib] V: 15.000 fps, codec=MJPG, frames=263, width=1024, height=768
[avilib] A: 44100 Hz, format=0x01, bits=16, channels=1, bitrate=705 kbps,
[avilib] 18 chunks, 1546440 bytes, CBR
[tcprobe] summary for MVI_0566.AVI, (*) = not default, 0 = not detected
import frame size: -g 1024x768 [720x576] (*)
frame rate: -f 15.000 [25.000] frc=0 (*)
audio track: -a 0
- -e 44100,16,1 [48000,16,2] -n 0x1 [0x2000] (*)
bitrate=705 kbps
length: 263 frames, frame_time=66 msec, duration=0:00:17.533
So for me it looks like CBR, not VBR. Maybe I did something wrong in CHDK? Normally I don`t take videos. It`s showing different bitrates while recording though.
@ewavr: Thanks for the clarification. The camera will stay 1.00H for now.
