Making a YT compatible audio file with image ffmpeg

[Yellow Pasque]

Your ffmpeg doesn't appear to be built with libvpx support :\
For that matter, it doesn't appear to support libx264 either.

[shantiq]

OH that must the reason for my problems here? i forgot when i did install back in March i was only thinking of audio

thanx Temüjin; looks like you have spotted the issue

will do a full reinstall on ffmpeg and report

thanx for your advice


===================


well full reinstall


and still REJECTED by YT

[FakeOutdoorsman]

Try adding "-loop 1":

ffmpeg -loop 1 -i image.png -i music.mp3 -c:a copy -c:v libx264 -crf 0 -preset veryslow -shortest output.mkv

or maybe:

ffmpeg -loop 1 -r 2 -i image.png -i music.mp3 -c:a copy -c:v libx264 -crf 0 -preset veryslow -shortest output.mkv

I tried several combinations of various options to try to break YouTube and the only ones it didn't like were without "-loop 1":

ffmpeg -i normal.png -c:v libx264 -crf 0 -t 10 testsrc-crf0.mkv
ffmpeg -i normal.png -c copy -t 10 testsrc-copy.mkv

[shantiq]

ha thanx for that research FakeO

i understand now that what i was trying to upload in earlier attempts was in effect a sound file with ONE image only

so this explains why it took just a few seconds to obtain and why YT rejects them. They are not video files only have the name of them

Of course now it takes the same time it takes Kdenlive but at least it is command line which i favour when choice is there

PS had to add

-s hd720

since my original image was 2300x2800 or somesuch and i only need 720p


Thanx to you and to Temüjin for help and time
marked as solved [YT is now happy!]

of course it now takes same time as Kdenlive

[FakeOutdoorsman]

had to add -s hd720 since my original image was 2300x2800 or somesuch and i only one 720p

Consider using "-vf scale=-1:720" instead of "-s hd720". In this example scale will automatically choose the correct width with your declared height to preserve aspect, otherwise -s can stretch or squish your output by make a "hard" resize to hd720 (1280x720).

actually s hd was fine in my case but problem is muxing takes possibly [?]longer than Kdenlive to process .... not sure why
and Kdenlive uses ffmpeg for its muxing ... mind you hard to tell about time since muxing never seems to take the same amount of time
i shall prepare the image so it is the size i want with Gimp first then remove size switches on the command ... that should reduce the time?

[FakeOutdoorsman]

-r 2 input, -r 25 output

$ time ffmpeg -y -loop 1 -r 2 -i image.png -i music.mp3 -c:a copy -c:v libx264 -crf 0 -preset veryfast -shortest -r 25 output.mkv
real    0m11.037s

-r 2 input

$ time ffmpeg -y -loop 1 -r 2 -i image.png -i music.mp3 -c:a copy -c:v libx264 -crf 0 -preset veryfast -shortest output.mkv
real    0m11.070s

Default (-r 25 input)

$ time ffmpeg -y -loop 1 -i image.png -i music.mp3 -c:a copy -c:v libx264 -crf 0 -preset veryfast -shortest output.mkv
real    2m9.211s

[shantiq]

is there a timer for processes on ffmpeg? i have never seen it. what do you need to add? or did you time it some other way?

my muxing took about 25 minutes on a 5 minute video

[FakeOutdoorsman]

I only added "time" to the commands, or you could use the "-benchmark" global option in ffmpeg if you only want utime/user/CPU time.

$ time sleep 5
real    0m5.022s
user    0m0.000s
sys     0m0.000s

$ time ffmpeg -y -f lavfi -i testsrc=d=60 -c:v libx264 output.mkv
...
real    0m1.987s
user    0m7.093s
sys     0m0.363s

$ ffmpeg -y -benchmark -f lavfi -i testsrc=d=60 -c:v libx264 output.mkv
...
bench: utime=7.037s
bench: maxrss=69480kB

‘-benchmark (global)’

Show benchmarking information at the end of an encode. Shows CPU time used and maximum memory consumption. Maximum memory consumption is not supported on all systems, it will usually display as 0 if not supported.

[shantiq]

thank you great tips!
never knew either were there...


ouch! on a 5 minute video

real 106m16.869s
user 64m12.836s
sys 2m37.396s

this my command

time ffmpeg -y -loop 1 -i amarilla.png -i bulgaria.mp3 -c:a copy -c:v libx264 -crf 0 -s hd720 -preset veryslow -shortest output2.mkv

will now time Kdenlive on same and it took 17 minutes

so that is still a huge discrepancy; not sure what they are using
here first one is the ffmpeg mux second kdenlive

mediainfo output2.mkv output.m2t
