Dear all, Hi. I am a newbie to GstOpenMAX. I want to get it work on x86 firstly. I followed strictly with the instructions on this page (<a href="http://freedesktop.org/wiki/GstOpenMAX">http://freedesktop.org/wiki/GstOpenMAX</a>). My working environment was Ubuntu 8.10 and I want to use Totem-gstreamer as the front-end. I compiled and installed all packages (gstreamer 0.10.22, Bellagio omxil, gstopenmax) and exported the environment variables. When I started Totem-gstreamer and choose to play a file, the problems occurred. For example, if I want to play a MPEG-4 file, the errors showed on screen saying that The playback of this movie requires the following decoders which are not installed: MPEG-4 AAC decoder MPEG-4 Video decode And here was the Log: [start] root@fiennes-810:~# totem-gstreamer Xlib: extension "RANDR" missing on display ":0.0". 0:00:14.160030999 30293 0x9e97018 INFO omx gstomx_base_filter.c:81:change_state:<omxmpeg4dec0> changing state NULL - READY ** (totem-gstreamer:30293): WARNING **: libomxil.so.0: cannot open shared object file: No such file or directory ** Message: don't know how to handle video/mpeg, mpegversion=(int)4, systemstream=(boolean)false, codec_data=(buffer)000001b001000001b58913000001000000012000c4f8404d8800cd16843c1463000001b24c61766335312e34302e34, width=(int)720, height=(int)480, framerate=(fraction)25/2 0:00:14.272662105 30293 0x9e97018 INFO omx gstomx_base_filter.c:81:change_state:<omxaacdec0> changing state NULL - READY ** (totem-gstreamer:30293): WARNING **: libomxil.so.0: cannot open shared object file: No such file or directory ..... [end] The gstopenmax seemed to start work but interrupt. I googled around and can't figure out what caused the problem. Actually I can not find the library libomxil.so.0. So could anybody give me some glues or suggesions ? Thanks a lot. Best wishes, Fiennes
