 Summary of the bug: Muxing .264 files, even ones which have been created
 by ffmpeg, cannot be muxed to playable MP4 files anymore.
 How to reproduce:

 [..]
 % ffmpeg -i foreman.264 -vcodec copy foreman.mp4

 The issue seems to be the lack of timestamps (possibly related to
 https://trac.ffmpeg.org/ticket/502). However, even adding -fflags +genpts
 and a frame rate via -r does not change the output, nor does it generate
 an MP4 file that can be played back.
 Older versions of ffmpeg did not have this issue. In particular, the
 ffmpeg version that comes with Ubuntu 16.04 (ffmpeg 2.8.14) happily muxes
 .264 files to MP4 with the commands above.
