Hi Michael.i'm using FFmpeg 2.4.1 built on gcc 4.4.7
(configuration: --prefix=/usr/local --enable-shared --disable-static
--bindir=/usr/local/bin --enable-gpl --enable-version3 --enable-nonfree
--disable-outdev=sdl --enable-memalign-hack --enable-runtime-cpudetect
--enable-pthreads --extra-cflags=-I/usr/local/include
--extra-ldflags=-L/usr/local/lib --extra-libs=-ldl --enable-zlib
--enable-bzlib --enable-avfilter --enable-libmp3lame --enable-libtheora
--enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265
--enable-libxvid --enable-libfdk_aac --enable-libschroedinger
--enable-libopus --enable-libspeex)

first, i've got well encoded result but with some error when using ffmpeg.

ffmpeg -i src.mp4 -i 200x200.png -filter_complex
"overlay=main_w-10:main_h-10" out.mp4
200x200.png: Input/output error
frame= 1266 fps= 76 q=-1.0 Lsize=    5595kB time=00:00:42.21
video:4888kB audio:662kB subtitle:0kB other streams:0kB global headers:0kB
muxing overhead: 0.825544%

second, i've got frame with no error when using
doc/examples/demuxing_decoding. i should keep digging with it :) thanks
