Hi,  ffmpeg version:   libavutil version: 49.7.0   libavcodec version: 51.62.0   libavformat version: 52.18.0   libavdevice version: 52.0.0 faac-1.26 faad2-2.6.1 I want to run openmax stand alone demo, could you test how to make it?

In my opinion this is not a problem of the relation between gstreamer and openmax but a decoding error inside the openmax audio decoder. The error in this case seems to be related to faac version that does not match. Which version of ffmpeg are you using? Did you try to run the openmax stand alone demo, in tests/components/audio/omxaudiodectest? -- Giulio Urlini xuefeng wang wrote: > Hi Felipe Contreras, > > Thank you very much. > > It works with "./gst-launch-0.10 filesrc > location=./music/matrix_128_96_MPEG-4_15fps_64kbps.mp4 ! qtdemux > ! omx_mpeg4dec ! ffmpegcolorspace ! videoscale ! ximagesink" while > turning off the TI workarounds. > > Another issue is found by "gst-openmax-0.10.0.4 + > libomxil-bellagio-0.9.0" (cannot reproduce by "gst-openmax-0.10.0.4 + > libomxil-B-0.3.3"): > > ./gst-launch-0.10 filesrc > location=./music/matrix_mp4sp_176x144_15fps_aaclc_44100hz_s_164kbps.mp4 > ! qtdemux name=demux demux. ! queue ! omx_aacdec ! audioconvert ! > audioresample ! volume ! osssink demux. ! queue ! omx_mpeg4dec ! > ffmpegcolorspace ! videoscale ! ximagesink > > [libfaad @ 0x8606a50]faac: frame decoding failed: Bitstream value not > allowed by specification > OMX-error in packet decoding in audio dcoder > [libfaad @ 0x8606a50]faac: frame decoding failed: Bitstream value not > allowed by specification > OMX-error in packet decoding in audio dcoder > > > > > */Felipe Contreras <felipe.contreras@nokia.com>/* 写道： > > On Thu, 2008-10-09 at 15:08 +0800, ext xuefeng wang wrote: > > I have the following issue: > > > > ./gst-launch-0.10 filesrc > > location=./music/matrix_128_96_MPEG-4_15fps_64kbps.mp4 ! qtdemux ! > > omx_mpeg4dec ! ffmpegcolorspace ! videoscale ! ximagesink > > Setting pipeline to PAUSED ... > > Pipeline is PREROLLING ... > > ** (gst-launch-0.10:17245): WARNING **: ffmpegcsp0: size 18432 is not > > a multiple of unit size 24576 > > ERROR: from element /pipeline0/ffmpegcsp0: subclass did not specify > > output size > > Additional debug info: > > gstbasetransform.c(1537): gst_base_transform_handle_buffer > > (): /pipeline0/ffmpegcsp0: > > subclass did not specify output size > > ERROR: pipeline doesn't want to preroll. > > Setting pipeline to NULL ... > > Caught SIGSEGV accessing address 0x3c > > #0 0x00110402 in _start () from /lib/ld-linux.so.2 > > #1 0x008c0119 in ??
