Hi,
does someone know about an issue about coding a video with ffmpeg (git-version, Jul 11 2011) and x264 (0.115.x) for older ipod/iphone 3G?
I'm trying to coding the video with the following command:
ffmpeg -y -i video.flv -acodec libfaac -ar 48000 -ab 128k -ac 2 -s 640x360 -vcodec libx264 -b 1200k -flags +loop+mv4 -cmp 256 -partitions +parti4x4+partp8x8+partb8x8 -subq 7 -trellis 1 -refs 5 -coder 0 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -bt 1200k -maxrate 1200k -bufsize 1200k -rc_eq 'blurCplx^(1-qComp)' -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -level 30 -r 30 -g 90 -async 2 video.mp4
Well, on an older version its working perfect (ffmpeg 0.5-30, x264 20100902-2245), but with the new version and the same command it's not possible to view the video with the older ipod/iphone versions.
I'm trying to view the video with safari.
Did something change so I have to take an other command? Does somebody have an idea?
Thank you very much for help.
