MP4Box Resolution unmatched between representation
30 janvier 2018, par Massimo Vantaggiofor one of the last stability tests i try with two representation instead the only one of before to get the adaptive bitrate streaming .
Below my encoding command :ffmpeg -y -i $name -i logo.png -c:a aac -b:a 256k -ar 48000 -ac 2 -async 1 -c:v libx264 -x264opts keyint=$GOP:min-keyint=$GOP:no-scenecut -bf 0 -r $FPSC -b:v 1060k -maxrate 1060k -bufsize 530k -profile:v main -t $FDUR -filter_complex "[0:v][1:v]overlay=main_w-overlay_w-10:10,scale=-1:478" format480.mp4
ffmpeg -y -i $name -i logo.png -c:a aac -b:a 384k -ar 48000 -ac 2 -async 1 -c:v libx264 -x264opts keyint=$GOP:min-keyint=$GOP:no-scenecut -bf 0 -r $FPSC -b:v 2400k -maxrate 2400k -bufsize 1200k -profile:v main -t $FDUR -filter_complex "[0:v][1:v]overlay=main_w-overlay_w-10:10,scale=-1:1080" format1080.mp4If for the first rapresentation i use 480p ffmpeg give me this error :
width not divisible by 2 (853x480)
Error initializing output streamIf i use for first representation 478p ffmpeg run correctly all two encoding but after when i try to load these two files on MP4Box to dash them live with the following command :
MP4Box -dash-live 8000 -subdur 8000 -profile dashavc264:live -mpd-refresh 240.0 -time-shift 24 -min-buffer 4000 -insert-utc -no-cache -out manifest.mpd format1080.mp4#video format480.mp4#video format1080.mp4#audio format480.mp4#audio
the error come back into mp4box :
"files have not-proportional layout 1920 x 1080 vs 849 x 478 but sample size and aspect ratio match, assuming precision issue"I would like to understand what i don’t know about, which are the resolutions that match, i understand that some movies have atypical resolution for example 1040 or 432 but the input video for this test is correct 1920 X 1080 and i wish to compress/encode it for dash and to create another representation with 480p, could i ask where I’m wrong ?
Thanks !

ffmpeg scale/forcing a video resolution issue
30 janvier 2018, par Massimo VantaggioI try to be sure that the
video comes out
with aresolution
of1920 x1080
,
If not the encodingmust force this resolution
.
I need this to create fine adaption set from a video input with standard resolution (HD).Im unable to get always this resolution, for example with a movie of
1920 x 1040 i get 1993 x 1080, below my ffmpeg command line :
ffmpeg -y -i $name -i logo1080.png -c:a aac -b:a 256k -ar 48000 -ac 2 -async 1 -c:v libx264 -x264opts keyint=$GOP:min-keyint=$GOP:no-scenecut -bf 0 -r $FPSC -b:v 2400k -maxrate 2400k -bufsize 1200k -profile:v main -t $FDUR -filter_complex "[0:v][1:v]overlay=main_w-overlay_w-10:10,scale=1920:1080" format1080.mp4
I tried every possibility that the ffmpeg scale page tells, without understand how to fix it.
I think i need some help,
Thanks,
