#3674: Just audio without video in windows decoder -------------------------------------+------------------------------------- Reporter: mfz | Type: defect Status: new | Priority: normal Component: avcodec | Version: Keywords: h264, | unspecified height, audio, windows media | Blocked By: player, internet explorer | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: I have a screen recorded video with frame rate 15, video codec H.264 (MP4) and AAC as audio. The target via FFmpeg should contain frame rate 25, height of 720 pixel and the codecs without change. After encoding, the file is playable in VLC player, Chrome browser (HTML5 video tag) and Firefox. In Windows Media player I just get the audio played (no video to see) and in Internet Explorer 11, I get an error ("Unknown source.") How to reproduce: {{{ % ffmpeg -i input_file.mp4 -vf "scale='(trunc((out_h*a)/2)*2):(min(720, in_h))'" output_file.mp4 VERSION: N-63439-g96470ca N-63439-g96470ca }}} Strange is: If I encode the video with a height of 718 or 722 (or any other height I tried), the video is playable anywhere - without problems. Test video file for input (short, length of 1 second): http://www.datafilehost.com/d/1ca920ac -- Ticket URL: <https://trac.ffmpeg.org/ticket/3674> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
