[mythtv-users] HD-PVR bitrate not being set in v29?

[Dan Wilga]

I recently noticed that my free disk space was creeping downward, and 
decided to investigate. I discovered that many recordings made since I 
switched from 0.28.2 to 29.1 are consistently larger--sometimes double 
or triple in size.

Looking further, I noticed that the bitrate of the HD-PVR (not HD-PVR2) 
recordings seems to be much higher than it should be. SoI checked the 
recording profiles in mythtv-setup. I have confirmed that the recordings 
rules in question are using my Low Quality profile, which has this for 
all three (low, med, high) resolutions:

Avg. Bitrate: 4500 Max. Bitrate: 6200

What is clear is that recordingsdon't seem to be using this value. 
Taking the output of mediainfo from a 0.28.1 recording and comparing it 
to that of a 29.1 recording of the same program on another night gives 
this diff:

# diff /tmp/1 /tmp/2

< Duration : 33 min 25 s

 > File size : 2.52 GiB

58c58
< Stream size : 91.8 MiB (11%)
---
 > Stream size : 91.8 MiB (4%)

At the same time, while a recording is ongoing, the output of "v4l2-ctl 
-l" gives these values:

video_encoding (menu)   : min=0 max=2 default=2 value=2
video_bitrate_mode (menu)   : min=0 max=1 default=1 value=0 flags=update
video_bitrate (int)    : min=1000000 max=13500000 step=100000 
default=6500000 value=13500000
video_peak_bitrate (int)    : min=1100000 max=20200000 step=100000 
default=9000000 value=20200000

The recording bitrates are maxed. It's as though the values in the 
profile aren't being used, even though they are in the range of 
acceptable values (once you multiply by 1000). Can Anyone else with an 
HD-PVR confirm this?
