[REPOST TO trac.ffmpeg.org] Speeding up video doesn't affect duration #369

Closed sdfdger closed 2 months ago

sdfdger commented 2 months ago

Posting here because https://github.com/FFmpeg/FFmpeg disabled the Issue tab

setpts speeds up the video, but the duration stays the same. The rest of the video is the last frame.

Version: https://github.com/BtbN/FFmpeg-Builds/releases/download/latest/ffmpeg-master-latest-win64-gpl.zip from "Latest Auto-Build (2024-04-30 12:51)" https://github.com/BtbN/FFmpeg-Builds/commit/1a3e916b912dcd3f89c4502803fb08284a586a78

ffmpeg -i "sampletext.mp4" -filter:v "setpts=PTS/10" "10x sampletext.mp4"

sampletext.mp4 10x sampletext.mp4

Please direct user questions at the appropriate channels(#ffmpeg IRC or ffmpeg-user ML). These issues are for issues regarding these builds specifically.

Someone should repost this to https://trac.ffmpeg.org

trac is not a support channel either, and this does not look like any kind of bug to me.
