[FFmpeg-user] Not able to get constant 25fps for H.264 HD Transport Stream after transcoding

[Mrukant Popat]

Dear All,

Below command line generates a Constant bitrate TS of 5000Kbps , but the
video elementary stream inside does not show 25 fps when using MediaInfo.
Infact when I play it with mplayer, it plays with 50fps. However, VLC plays
with 25fps.

Here is the command line

ffmpeg.exe -loglevel debug -i input.ts -pix_fmt yuv420p -r 25.0 -c:s copy
-c:v libx264 -preset slow -tune film  -x264opts
tff:fps=25.0:bitrate=4500:ref=3:threads=6:no-scenecut
:keyint=50:vbv-bufsize=180:vbv-maxrate=4500:videoformat=pal -c:a libfaac
 -ab 192000 -ar 48000 -f mpegts -mpegts_pmt_start_pid 0x64 -map 0:0 -map
0:1 -map 0:2 -
map 0:3 -streamid 0:1000 -streamid 1:1001 -streamid 2:1002 -streamid 3:1005
-muxrate 5M output.ts > c:\commandoutput.txt 2>&1



Here is the link to detailed output to this command --->

I am looking to get video with 25 fps and also the value of 25 fps set in
VUI of SEI inside H.264 stream.


Thank you,
