When I run this command: gst-launch -v filesrc location=/spiderMan3.mp4 ! qtdemux name=demux demux.audio_00 ! queue max-size-buffers=8000 max-size-time=0 max-size-bytes=0 ! TIAuddec1 ! alsasink demux.video_00 ! queue ! TIViddec2 ! TIDmaiVideoSink videoStd=D1_PAL videoOutput=COMPOSITE

it shows this error

I use cat to check cmem module as follow.

 [root@HUALU omap3530]# cat /proc/cmem

Block 0: Pool 0: 1 bufs size 5251072 (5250000 requested)
Pool 0 busy bufs:

Block 0: Pool 3: 1 bufs size 4096 (1 requested)
Pool 3 busy bufs:

But I can play avi file. I played mp4 file successful once time.
my bootargs is setenv bootargs 'mem=99M console=ttyS2,115200n8 console=ttyS0 root=/dev/mmcblk0p2 rw rootfstype=ext3 rootdelay=1 omap-dss.def_disp="hdmi" omap_vout.vid1_static_vrfb_alloc=y omap_vout.video1_numbuffers=3 omap_vout.video1_bufsize=829440 omap_vout.video2_numbuffers=0'

what is wrong ?

    The CMEMK error seems fairly straight forward in that it could not allocate a pool of the necessary size, so if this is the real problem than you may need to adjust your CMEM configuration to have additional pools of the large enough size. To start I would probably try to ensure that there are really sufficient CMEM pools available, since the error itself seems so simple.

    On the other hand if this is a failure of GStreamer to request the proper number and size of CMEM pools (i.e. it is allocating too many for some reason with MP4 or otherwise doing so incorrectly) than you may want to consider submitting it as an issue to the GStreamer project https://gstreamer.ti.com/gf/project/gstreamer_ti/.
