[FFmpeg-devel] Problem when remuxing mpeg4 from mp4 container to ts container

(I recently posted this on -user, but as I fear this might be a bug, I
decided to also post here (-devel).)
I have a problem where the resulting file from the following commands
produce a transport stream file that does not display video.
(Any mp4 file will probably be fine, but I used that one.)
Reencode the h264 video into mpeg4:
ffmpeg -i big_buck_bunny_480p_1mb.mp4 -acodec copy -vcodec mpeg4
Then convert the container from mp4 to transport stream:
ffmpeg -i big-mpeg4.mp4 -codec copy big-mpeg4.ts
The resulting file "big-mpeg4.ts" cannot be played by ffplay. It prints
tons of logs, but this one seems most important.
[mpeg4 @ 0x7f9af80008c0] [IMGUTILS @ 0x7f9afe8bb420] Picture size 0x0 is
Please note that if the operations are done in one single step, like this:
ffmpeg -i ~/streams/big_buck_bunny_480p_1mb.mp4 -acodec copy -vcodec mpeg4
... ffplay has no problem, video is shown.
This behaviour is the same on these two ffmpeg versions:
ffmpeg version 2.8.8-0ubuntu0.16.04.1 Copyright (c) 2000-2016 the FFmpeg
developers (ubuntu 16.04 standard)
ffmpeg version N-82217-gb642290 Copyright (c) 2000-2016 the FFmpeg
developers (built myself)
Any ideas what could be wrong here?
