tpad filter doesn't work with -r on input

[occvtech]

I'm trying to use the tpad filter on file inputs that also need their framerate changed. If I use the -r flag on the input file, the output ends up duplicating the last frame of the file for a really long (arbitrary time), and throws an error saying "More than 1000 frames duplicated'.

Here's an example of the command:

ffmpeg -r 15 -i INPUT -filter_complex "[0:v]tpad=stop_duration=5[out]" -map [out] OUTPUT

If instead, I remove the -r 15, and instead use the -framerate flag or the frame rate filter, then the command works properly.

Please provide the command line you tested together with the complete, uncut console output to make this a valid ticket.

Is this what you needed? I just copied all the content out of the console for this. If you need it formated another way, please let me know.

One particular area that is interesting to note is the "More than 1000 frames duplicated". This only appears when the framerate flag is included.

Thanks again for your help!

Does the above provide the details you need? If I can help in any other way, please let me know.

As workaround use -framerate demuxer option instead of -r
