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

Xavier Benech Thu, 04 Sep 2014 02:37:14 -0700

(sorry for the repost, this one includes a link to input video)

Hi,

I try to encapsulate mp4 video (h264/aac) into an mpeg-ts containerusing ffmpeg but it produces invalid videos if the framerate (fps) isvery 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


Input video is available here:
https://www.dropbox.com/s/1aarhpd4ayerx23/passthrough.mp4?dl=0

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
