GStreamer | gst-plugins-bad | 0.10.25
Summary: FAAC bitrate setting has no effect
Classification: Desktop
Product: GStreamer
Version: 0.10.25
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-plugins-bad
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: mike.dyer at provision-comm.com
QAContact: gstreamer-bugs at lists.sourceforge.net
GNOME target: ---
GNOME version: ---
When setting the bitrate on the faac plugin, the resulting bit rate is always
~128kbps
Can reproduce using:
gst-launch -v audiotestsrc is-live=true wave=9 do-timestamp=true
num-buffers=450 ! audio/x-raw-int,channels=2,rate=44100,width=16 !
audioconvert ! faac outputformat=1 profile=2 bitrate=8000 !
ffmux_mpegts ! filesink location=8mbps.ts
gst-launch -v audiotestsrc is-live=true wave=9 do-timestamp=true
num-buffers=450 ! audio/x-raw-int,channels=2,rate=44100,width=16 !
audioconvert ! faac outputformat=1 profile=2 bitrate=128000 !
ffmux_mpegts ! filesink location=128mbps.ts
ls -l *.ts gives:
-rw-rw-r--. 1 mike mike 234436 2010-01-08 10:13 128mbps.ts
-rw-rw-r--. 1 mike mike 232556 2010-01-08 10:13 8mbps.ts
Two files of about the same size, for two very different bitrates.
System is: Fedora Core 12, gstreamer version 0.10.25, gst-plugins-bad version
0.10.17, faac version 1.28
