I am trying to compile ffmpeg for use with a single video type (MP4 /

Here's what my compiler flags are (non-working), can someone shed some
light on this for me, as Video Codecs are not my strong suit.

FLAGS="$FLAGS --disable-everything"
FLAGS="$FLAGS --enable-encoder=mpeg4video"

Code in use that shows failure:

// Open video file (here's the failure, doesn't happen when compiled for all)
inputFormat = av_find_input_format("MP4");
if (!inputFormat) {
    __android_log_print(ANDROID_LOG_ERROR, "NDK:", "Null inputformat!");

When I simply build for everything this works fine, but I do not know
what else I need to include to support decoding of Mpeg4 video files.
