IMX6 gstreamer pipeline segfault using mfw_mpeg2decoder

[santox]

Hi All,

i'm working with a dvb-t dongle, aiming to watch tv on a MX6Q.

i'm using ltib filesystem with kernel 3.0.35

this is my not-working pipeline:

gst-launch-0.10 dvbbasebin bandwidth=8 code-rate-lp=AUTO code-rate-hp=AUTO guard=AUTO hierarchy=AUTO modulation=AUTO trans-mode=AUTO inversion=AUTO frequency=$f program-numbers=$pn ! mpegtsdemux name=demux ! queue max-size-buffers=0 max-size-time=0 ! mfw_mpeg2decoder ! mfw_v4lsink axis-top=0 axis-left=0 disp-width=$WIDTH disp-height=$HEIGHT axis-top=$Y setpara=1

! consider that substituting mfw_mpeg2decoder with ffdec_mpeg2video there is not segfault (but video has frames dropped) !

please give me an hint to solve this problem!

this is my console output:

good news: using vpudec is working for mpeg2 decoding.

But i'm still in trouble trying to replace 'mpegtsdemux' (aiurdemux should have better performance, am i right ? ) and 'mad' for audio decoding... beepdec doesn't work for me, neither for simple mp3 file playback.

this is my current pipeline:

gst-launch-0.10 dvbbasebin bandwidth=8 code-rate-lp=AUTO code-rate-hp=AUTO guard=AUTO hierarchy=AUTO modulation=AUTO trans-mode=AUTO inversion=AUTO frequency=$f program-numbers=$pn ! mpegtsdemux name=demux ! queue max-size-buffers=0 max-size-time=0 ! vpudec ! mfw_v4lsink axis-top=0 axis-left=0 disp-width=$WIDTH disp-height=$HEIGHT axis-top=$Y setpara=1 \

demux. ! queue max-size-buffers=0 max-size-time=0 max-size-bytes=0 ! mad \

! audioconvert ! 'audio/x-raw-int, channels=2' ! alsasink &

hoping somebody can help!
