hi, how do i make a video with an animated gif and music? i'm

with ffmpeg, to convert a gif to video you can use:
ffmpeg -f gif -i dumb_gif.gif out.webm

to add audio give your audio track as input:
-i audio_track.mp3 -codec copy

but, if you need to re-encode the audio to something compatible to a webm use
-i audio_track.mp3 -c:a libvorbis

that's great man, thanks!!
but the gif cycles just once. how does one make it loop through all the music length?

>>334114
ffmpeg -f gif -i dumb_gif.gif -stream_loop -1 --i audio_track.mp3 -c:a libvorbis -shortest out.webm

-stream_loop -1 should loop the gif indefinitely. -shortest stop the encoding when shortest steam end, since the video stream is "infinite" it should stop at the end of the audio stream.

unfortunately i get ad "Unrecognized option 'stream_loop'" error.

looking on the internet about that stream_loop error, i found some instructions to create an infinite loop by linking explicitly hundreds of single loops, using a name list stored in a text file.

do you think it is a valid alternative?

>>334210
just tried on my machine and it should be working (but the -shortest option is not necessary apparently).
Are you using an older version? mine's 3.3.2. I'm not sure about it but I think in older versions this option was simply called "-loop"

>>334298

ok, i removed the ffmpeg version i had downloaded from the repositories and compiled the 3.3.2 version. this solved the stream_loop option problem. then it told me that i haven't got any libvorbis codec, and i installed it and recompiled ffmpeg.

now it works fine, except for two things:

- it fails creating .webm files, cause vp8 encoder is apparently disabled. no problem though, cause an .mp4 should work fine as well.

- in making an .mp4 video, if i keep the 'shortest' option, the output video is just 0.6 seconds in length, that is just one cycle of the gif. if i remove that option, the video length is correct, but the gif loops just once and then freezes for the rest of the time.

i really don't know what to do.

i also tried to hack with -vframes option, or changing the -1 parameter of -stream_loop option to 0 or 100 but it doesn't affect the output at all

if ffmpeg aint working you could always try to grab shotcut

compile option should be --enable-libvpx

yeah, sorry you are right, I didn't notice the gif would stop looping. The manual (https://ffmpeg.org/ffmpeg-formats.html#gif-1) says that the gif demuxer has an option which default to 1 (causing the gif to not loop), so finally it should be:
ffmpeg -ignore_loop 0 -i 1497890724216.gif -i audio.raw -c:a libvorbis -shortest out.webm
with this I get the gif correctly looping on the audio.

>as an option which default to 1
the option is "-ignore_loop 1"

>>334493

damn son, it worked! thank you very much for your effort!

>>334491
i'm gonna try this as well, thanks
