FFMPEG want to Keep the bitrate constant.

How to fix to Mpeg2-TS bitrate.

I want to create the MPEG2-TS(Static Bitrate) & specify PID.
I can specify PID by FFMPEG , but it cannot create MPEG2-TS(Static Bitrate).

Therefore,
Step 1: I used Adobe Media Encoder to create CBR file.(This file is really static bitrate).
Step 2: I used FFMPEG to the CBR file into specify PID(command: -vcodec copy -acodec copy).

But It cannot static!!

Anyone know how to fix the bitrate by FFMPEG??


//Except [-b:v 2500k -minrate 2500k -maxrate 2500k] it is only way to x264.

How are you measuring the bitrate? or determining if it's static (or not) over time ?

Did you try specifying -muxrate ? Or else try tsmuxer CBR (I think it inserts padding)

Thanks a lot!! -muxrate can static messuring bitrate.

But When I use -muxrate code, The error of below came out.

[mpegts @ 00000000005827a0] dts < pcr, TS is invalid



Do you know happen to know this one?


My all code is below.

ffmpeg -i input.ts ^
-vcodec copy -acodec copy ^
-muxrate 14500k ^
-c:v copy -c:a copy ^
