I have no experience with S3, but this Stackoverflow thread seems to
suggest you need to use the "aws s3 cp" command:

https://stackoverflow.com/questions/54736246/stream-ffmpeg-transcoding-result-to-s3

I *guess* ffmpeg assumes it can seek on HTTP PUT output URLs, which
doesn't work on AWS S3. Instead, when piping with above command, ffmpeg
doesn't use this assumption. But I may be wrong.

Please try this.

Cheers,
Moritz

[FFmpeg-user] Output to S3

[Bohdan Fihar]

Hi,

How can I output a video file to AWS S3 either public bucket ot Presigned
url ?
I tried
*ffmpeg -i small.mkv -f matroska -movflags frag_keyframe+empty_moov -method
PUT https://[my-bucket-name].s3.us-east-2.amazonaws.com/video/output.mkv
*

bur it won't work, fails with

Re: [FFmpeg-user] ffmpeg http filter?

[Alex]

Server just do post processing of raw rgb image/frame and return it as response 
for request.Something like so: POST http://localhost:8080

I don't think it's possible using filters, or with a single invocation like 
that. (The 'http' filter is hypothetical and just meant for illustration right?)

Depending on how you're connected to the server, I think pipes or sockets would 
be a better place to start. And also separate commands for outputting frames 
for the server to consume, and another that takes the returned images.

Re: [FFmpeg-user] Output to S3

[Bohdan Fihar]

Hi Moritz. Thanks for the answer.
I can't rely on "aws s3 cp", since it can be not installed on a machine
where I will run ffmpeg.

Do you know what this error means ?

If I understand correctly: use two outputs.  One for the rawvideo
which goes over some network protocol to your server and one for that
jpeg output.

I would assume "-map 0:v" *only* tries to map image attachment, no
audio. What's the second file good for anyway, if you're taking the
image from the first one?

And "_desposition:v" should throw a warning or an error. It will be
interpreted as an output file, not an option. (Even if you replaced "_"
with "-", the option is still misspelt.

Same here. And your stream indices are incorrect.

This is not useful. Show us the actual command you tried, and its
complete, uncut console output. Then we can correlate the input and
your options to your error messages, and point out where you are going
wrong.

I would say metadata and video "stream" (attachment) do not relate, but
I may be wrong and Mediainfo may be weak with AIFF files - I don't
know.

Each and every format has it quirks on where that is stored, and ffmpeg
tries to implement that best it can.

Generally, there should be. ffmpeg did have some limitations in the

Well, then we can't interpret the errors. ;-)

Re: [FFmpeg-user] ffmpeg http filter?

[Alex]

Hi! Thank for reply, but no I need next logic:

input.jpg => (ffmpeg decode image/video) => (ffmpeg scale frame to 600x600 pix 
and convert frame format to rgb24) => (ffmpeg send frame to remote address 
localhost:8080 for post processing of image/frame) => (ffmpeg get result image 
from remote server, format + add overlay) => (ffmpeg encode frame/image to 
output format) => out.jpg

Re: [FFmpeg-user] Correct conversion of yuvj420p?

Dear Paul,

What would be the right commandline to losslessly convert this to FFV1?
I've tried, but so far I get differing streamhash MD5s for the video -
regardless if I set the color range :(

ffmpeg -i input_video.mov -vf setrange=limited -c:v ffv1 out.mkv

That command will tell ffmpeg that range is not full but limited
and will not do lossy conversion with swscale at all.


That worked! Thank you!
Streamhash says it's a match :)



You will need to signal that encoded video is still full range somehow in 
container,
otherwise you will get correct hash but output display will think
its really limited while it is actually still full range.


Thanks for pointing that out.
I've done the following:

$FFMPEG -i $VIDEO_IN -an -c:v ffv1 \
 -vf setrange=limited \
 -pix_fmt yuv420p \
 -color_range jpeg \
 -colorspace smpte170m \
 -color_primaries bt709 \
 -color_trc bt709 \
out.mkv

The streamhash matches, and the color interpretation metadata seems to 
be identical to the source:


  * Source video (h.264):
    yuvj420p(pc, smpte170m/bt709/bt709)

  * Target video (ffv1):
    yuv420p(pc, smpte170m/bt709/bt709)



Thanks again Paul!

[FFmpeg-user] Problem with time-lapse

[Jippo12]

  Hi!

I'm trying to automate time-lapse video from still images. I have all sky
camera that captures around 200 images / night. I've managed to do videos
like this
https://drive.google.com/file/d/1yyihZNypBy0r5y_JJiTHgtvc8N1RAZ3e/view?usp=sharing

However what i'm looking for is for smoother video. Is it possible with
ffmpeg?

I've tried to clone every image 30 times etc but still fail to get good
results. I've tried to search ffmpeg man pages and the web but no success.

I use python script to automate the whole process. so below is some option
ive tried

os.system('ffmpeg -i ' + workdir2 + '%d.jpg  -vf '
'"tblend=average,framestep=1,setpts=0.50*PTS,minterpolate"'  + ' -r 30 -b:v
64K -crf 10 -an ' + destinationdir + videofile)
os.system('ffmpeg -r 30 -i ' + workdir2 + '%d.jpg -vcodec mpeg4 -qscale 1
-y -filter:v '" setpts=2.0*PTS"' ' + destinationdir + videofile)

That is a very small window of view into the error you got, I'd try using the

but what I might start with when I do the throw all of it on the wall and see

Yes, it's rather misleading isn't it. Based on what the ff* tools tell you,  
what you tried (or at least one of them) should definitely have worked. The 
problem is that the output from the commands you used to determine your plan is 
not really an accurate description.

The output from mediainfo gives some indication that something is different; 
unusual; the video "stream" reported by ffprobe isn't really another stream. 
And when you think about it, it makes sense. It's an aiff format file, how is 
it going to have a video stream?? I don't even think it can have multiple 
streams of any kind (at least the "simple" kind, not the ones that are saved by 
drum machines and sequencers and whatnot. Think those get a different extension 
anyhow).

The answer is that the metadata and cover image are in an id3 tag. Use 
-write_id3v2 true with the aiff muxer to force it to write one. It's disabled 
by default for good reason though, chances are other applications than iTunes 
(and now its various spawns) won't expect, or look for one.

Ted Park

Ehh, you are doing fine. Start by doing a "reply to all", and your email

[Tim] Here is the command line output of both tests one after the other…

What this seems to show is that FFprobe is installed, and runs 
correctly, giving reasonable output. That makes it more likely that the 
log entries you posted are noting a successful run of FFprobe, instead 
of a failed run.  I think that puts the ball back in the PinballBrowser 
court. Is it getting the same result when it calls FFprobe?  And that is 
a question for them, not for this list.

Perhaps some differential diagnosis could be helpful. It sounds like the

Tests you asked for:

"The first log entry appears to show how the app called FFprobe. You

It might be the option, but it will be the last option I'd like to accept.
I'm seeking for more simple solution.
I'm afraid that I'll stuck on sending a video to that server too.

I tried several video formats with this command:
ffmpeg -i sample_640x360.ts -method PUT

The bucket (its name is changed here) is public and I was able to send data
to it by Http Put request from the C# code sample.

I tried several video formats.

Re: [FFmpeg-user] Problem with time-lapse

Timelapse can be counterintuitive sometimes.

Sometimes you need to slow the framerate down, sometimes you need to raise it. 

Sometimes you need less frequent captures (or a step in the middle where you 
approve/reject the pictures that are going to be your frames), and sometimes, 
you need to capture at a much higher rate.

I think this case it is a matter of not enough captures to make a good 
timelapse video.

Also, maybe interpolating/duplicating frames is actually counterproductive by 
giving you a less clean starting point? I think the simplest timelapse render 
looks pretty good, from there maybe you can minterpolate but I'm not sure if 
the filters before minterpolate help.

This is just a general tip, I can excavate the command from that, but it would 
be immensely helpful if you put it into a line you can feed into a shell and 
also attach the output.
