Hello Carl,
Thank you for responding.
The video that I was transcoding has a specific location for I-IDR frame
placement.
I want to create CBR H.264 version of the video and VBR H.264 version.
Once the video is done transcoding, I use the "elementary" core in
commercial MPEG2 muxer for outputting MPEG2-TS file. When I exported
MPEG2-TS and then analyzed with MPEG2-TS analyzer, I've noticed that
explicit positions that I've indicated in FFMPEG are not being adhered to
in CBR version of the file. Up on further analysis and more "explicit"
output from FFMPEG, I've noticed that POC (picture order count) is
different in CBR and VBR versions. My general understanding of the
situation is such that the difference between CBR and VBR should not be in
area of POC (picture order count). Hence, I'm not sure if this is an issue
that derives from FFMPEG or libx264, it might be the latter, but could be
the FFMPEG '-force_key_frames' option. I think POC should be the same for
CBR and VBR.
Here is my command line for the CBR and VBR outputs:
