I'm trying to concat a video (mp4) and an audio (mp4 or aac) - both cut out using
-t from the same mp4 file. I'd like to basically freeze the last frame from the video and then append the audio.
I've tried using the concat demuxer
-f conat and
-c copy, but it produces a video of wrong duration (much longer than it should be, so I'm thinking some PTS are wrong in the audio, how can I reset them?). Also, bad output using
I also wonder if it's possible to do whole treat in one call of ffmpeg making use of
filter_complex: apply certain filters to one part of video (
drawtext), then freeze a frame and continue audio as is.
