Known Issues

  • AAC decoder: ADIF format does not support seek mode.
  • The open source Type finder can not correctly recognize some mp4 and AAC type.
  • With Totem player, the open source visualization effect cost about 300 system MIPS resource.
  • The VPU does not support GMC and OBMC feature.
  • The accurate seek mode could have a little long time delay.
  • Cheese limitation:

->The "video effects" and "Image properties" are disabled to get better performance.

-> The video recorder can only reach about 15 fps for VGA resolution.

-> The "totem" and "cheese" can not be executed simultaneously because of the v4l driver does not support two instance.

-> The “take photo” action will flash the UI in current solution.

Notes

  • The gstreamer set the AAC as the default AAC decoder, For the purpose of test AACPlus vectors please remove the mfw_aacdecoder by remove the /usr/lib/gstreamer-0.10/libmfw_gst_aacdec.so.
