Hi, I have an older build of ffmpeg (1.1.3) on my Mac and I'm able to put a list of png images in a file and use ffmpeg to create a h264 encoded movie.
Trying to do the same thing on a PC with the most recent build (ffmpeg-20151205-git-a16243a-win64-static) results in "DTS" errors and a file that has just a couple frames in it. A large number of images produces a massive stream of errors. I saw https://trac.ffmpeg.org/ticket/4765 and the related discussion http://ffmpeg-users.933282.n4.nabble.com/DTS-Out-of-Order-DTS-amp-PTS-Invalid-Dropping-td4667944.html and it seems related to what I'm seeing. It sounds as if the simple case of creating a movie just from images has regressed. For a testcase, I've uploaded some loopable public domain test images to http://imgur.com/a/TVyJT (under Post Options at the bottom, choose download album) The commands I run are (in a bash shell) printf "file '%s'\n" ./*.png > test_ffmpeg.list ffmpeg \ -f concat -i test_ffmpeg.list \ -r 30 -pix_fmt yuv420p \ -c:v libx264 -preset slow \ Muybridge_race_horse_animated.mp4 On my Mac, this creates a nice loopable movie. On the PC it creates a 2-frame movie. Am I doing something wrong or is there a bug? Thanks, Roger p.s. logfiles & script are at https://gist.github.com/rogerallen/426203d3a580898bd864 _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
