New description:

 Apparently, ffmpeg (at least version 2.0.2) has a mal-functioning "ffv1"
 codec. The attached program replicates the problem. It was extracted from
 the example section of the ffmpeg manual (http://ffmpeg.org/doxygen/2.0
 /doc_2examples_2muxing_8c-example.html), slightly modified to force the
 FFV1 codec by replacing lines 419-421 (with video_st = add_stream(oc,
 &video_codec, AV_CODEC_ID_FFV1)). It used to at least, before the updated
 to 2.0.

 Compiling and linking:

 {{{
 clang -I/opt/local/include test.c -L/opt/local/lib -lavutil -lavcodec
 -lavformat -lswscale -lswresample -o ffmpeg_test
 }}}

 Running:

 {{{
 ./ffmpeg_test test.avi
 }}}
