Hi! I'm afraid there is nothing can be done on the kernel side. It seems userspace app is trying to load dynamic library and fail with it, so it is why video can't be played. The library could be requested on linking stage or runtime via dlopen() call.

It plays MP4 files without any problems. It uses the hardware accelerator (IVA-HD) on omap4 in galaxy nexus to decode the video. However, I want to use software decoding instead of the hardware accelerator. Is having your own decoder (ffmpeg etc) the only way to do software decoding? Under /system/lib I see the following files: libstagefrighthw.so libstagefright_soft_mpeg4dec.so libstagefright_soft_h264dec.so My guess is that libstagefrighthw.so is for hardware decoding while the other two are used for software decoding. I naively thought that removing libstagefrighthw file would make the software decoder be used. Unfortunately, after removing that file, the app just throws an error saying "the video cannot be played". Is there anyway for using the in-built software decoder? I have unlocked the phone and can load my custom kernel (in case there is anything to be done on the kernel side, I am up for it!).
