Hi Carl, libstagefright.cpp compiles now, but I'm still getting the posix_memalign error when compiling libavutil/mem.c, but I guess that is something related with my environment configuration. However, I was able to decode h264 videos using libstagefright from outside ffmpeg. I mean, I compiled ffmpeg without libstagefright and, from my app, I read the frames using FFmpeg and decoded the packets using libstagefright. So I won't need more help on this, but if you need more information to reproduce this issue, please let me know. Despite the compilation issue, after being working with stagefright these days, I think (because I didn't test it), that the FFmpeg libstagefright_h264 decoder will have problems when the libstagefright decoder returns a buffer in QOMX_COLOR_FormatYUV420PackedSemiPlanar64x32Tile2m8ka format. This weird format is a tiled NV12 one and, as far as I know, FFmpeg libstagefright_h264 decoder does not handle it properly. Reading the code in "libstagefright.cpp", you can see that this format is treated as AV_PIX_FMT_YUV420P (this is done in Stagefright_init function). To treat this format properly, you should "untile" the buffer returned by the stagefright decoder and treat the result as an AV_PIX_FMT_NV12 buffer. Thanks!! Abel.
