[FFmpeg-user] Trouble with h264 video in mpeg ts container

Hi,

I try to encapsulate mp4 video (h264/aac) into an mpeg-ts container 
using ffmpeg but it produces invalid videos if the framerate (fps) is 
very low (<1). It works just fine for standard fps (like 25). If fps<1, 
the output is containing only audio.

Is there a way to make this work correctly? Or anyway workaround?

By the way, yes, I really need this very low fps for my usage... ;-)
Thanks for any help...

I'm using ffmpeg 2.3.2 release but reproduce same behaviour with 2.3.3.

I made the conversion using the cmd:
ffmpeg/bin/ffmpeg -i tests/converted/passthrough.mp4 -y -map 0 -c copy 
-f mpegts -bsf:v h264_mp4toannexb tests/converted/passthrough.ts

Full output here (files probing output below):

 > ffmpeg/bin/ffmpeg -i tests/converted/passthrough.mp4 -y -map 0 -c 
copy -f mpegts -bsf:v h264_mp4toannexb tests/converted/passthrough.ts
