Bug ID: 750989
Summary: Pipeline with aacparse fails to play stream
Classification: Platform
Product: GStreamer
Version: 1.4.5
OS: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: gst-plugins-good
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: jan.steffens at gmail.com
QA Contact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
I've got a live stream here that plays fine in FFplay/MPV but fails to play in
GStreamer if aacparse is present.
Recording: http://pkgbuild.com/~heftig/foob.flv (Created via rtmpsrc !
filesink)
Failing pipeline: GST_DEBUG='*:WARNING,aacparse:LOG' gst-launch-1.0 filesrc
location='foob.flv' ! flvdemux name=demux multiqueue name=mq demux.video !
mq.sink_0 demux.audio ! mq.sink_1 mq.src_0 ! h264parse ! avdec_h264 ! queue !
videoconvert ! xvimagesink mq.src_1 ! aacparse ! faad ! queue ! audioconvert !
pulsesink
Working pipeline (aacparse removed): GST_DEBUG='*:WARNING,aacparse:LOG'
gst-launch-1.0 filesrc location='foob.flv' ! flvdemux name=demux multiqueue
name=mq demux.video ! mq.sink_0 demux.audio ! mq.sink_1 mq.src_0 ! h264parse !
avdec_h264 ! queue ! videoconvert ! xvimagesink mq.src_1 ! faad ! queue !
audioconvert ! pulsesink
The only interesting debug message seems to be
0:00:00.021212666 14233 0x7f91cc003000 DEBUG aacparse
gstaacparse.c:290:gst_aac_parse_sink_setcaps:<aacparse0> setcaps: audio/mpeg,
mpegversion=(int)4, framed=(boolean)true, stream-format=(string)raw,
rate=(int)44100, channel
s=(int)2
It reports the caps with channels=(int)2, even though the stream is mono.
