As said it works for me with a 32 stream (video+audio) file, because after "Too
many streams", it tries other demuxers:
[matroska,webm @ 0x16b8a20] Too many streams               
LAVF_header: av_open_input_stream() failed

Could you try with a file with too many audio streams (instead of subtitles) or
make your sample available so we can try to reproduce the problem?

The FFmpeg problem is known, see issue963.
