I am currently developing an app which involves uploading video to the server. The video is on .MOV format since it comes from an iOS Device. I have set-up FFMPEG on the server already. But everytime I try to upload a video, an FFMPEG error comes out:

):

app/controllers/v1/businesses_assets_controller.rb:33:inupload_video'
Anyone who also got the same error as mine? How did you solved it?
The key part of the message is 'The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it'.
You need to add this flag to your ffmpeg command. For example the following command, which will compress an mp4 video, contains this flag:
ffmpeg -i BigBuckBunny_320x180.mp4 -strict experimental -acodec aac CompressedBBB_320x180_aac.mp4
Fixed it by installing the latest FFMPEG.
Followed this guide: https://gist.github.com/xdamman/e4f713c8cd1a389a5917

Problem
Recently I uploaded App preview video to my app in iTunesConnect
It looks like it was uploaded successfully, I was able to play it but there was a text overlay on the video preview:
Processing App Preview
The app preview can take up to 24 hours to process.
I have closed Safari and go to sleep. Next morning I see this
Questions
How can I get a reason why this happens, as far as I see my video conform to https://help.apple.com/app-store-connect/#/dev4e413fcb8 , here is ffprobe output for it

Who actually does this video review? Humans or machines?
Is there any automation script to do this validation before upload?
Silly me, looks like 24 hours wasn't passed, once I waited more time this problem just gone
P.S. only Safari show this, there is no error in Google Chrome
P.P.S sometimes it happens even for successfully processed video but after a page refresh, the problem is gone
I encoded a series of 16-bit grayscale PNGs to a lossless video with the following command:
ffmpeg -i image%04d.png -crf 0 -c:v libx264 -preset veryslow output.mp4
I am now trying to verify that the conversion to video was truly lossless by pulling out the PNGs at the same quality. The command I'm using:
ffmpeg -i output.mp4 image%04d.png
However, this is outputting 8-bit PNGs. I've tried various options I've read about such as -vcodec png and -qscale 0 but so far nothing appears to make it output 16-bit PNGs.
How do I extract all frames from the video at the same quality as they were going in? Or did I make a mistake in creating the lossless video in the first place?
Edit: I get this error message when trying to use -pix_fmt gray16be.

I'm happy to use a non-ffmpeg solution if there is one.
Your lossless video is 8-bit, as that's what x264 has encoded to. And in any case, x264 does not go above 10-bit (for which you would need a standalone encoder, or a different ffmpeg binary).
-c:v ffv1 is lossless and can encode to 16-bit gray (gray16le) or 16-bit RGB (e.g. rgb48le)
That swscaler line is a warning, not an error. FFmpeg does report the output as 16-bit per channel,
Stream #0:0(und): Video: png, gray16be, 512x512 ...
but you've already lost fidelity with the downgrade of the bit depth when you encoded to H.264.
I'm unclear on what the pixel format of the input PNGs is - RGB with no hint of hue, or a monochannel encoding? I suspect the former, in which case, use
ffmpeg -i image%04d.png -c:v ffv1 output.nut
Then you can do a compare with
ffmpeg -i output.nut -i image%04d.png -filter_complex ssim -f null -
A readout of
SSIM R:1.000000 (inf) G:1.000000 (inf) B:1.000000 (inf) All:1.000000 (inf)
indicates full fidelity.
I'm facing an issue using ffmpeg to convert video, precisely mp4 video => Http Live Streaming (HLS)
Once converted to HLS, the .m3u8 file has a wrong duration (e.g : 20,1s instead of 20.00s), causing bugs when playing it with AVPlayer on iOS.
Playing the video with Safari cause the same issue.
Example :
1) Open Safari
2) Play this video that i've converted
3) Look at the download progression, stopped at 98% cause of wrong duration.
4) When you slide between 98% and 100%, the video player can crash.

I had the same error. In my case it was because of carrierwave-video is incompatible with streamio-ffmpeg (3.0.2). streamio-ffmpeg expects to receive array of format_params, but carrierwave-video returns a string. I fixed it in my fork
I ve tried to upload videos using Carrierwave-video & FFmpeg. I've installed FFmpeg and there is no problem with installation. I have made configurations (I'm not sure from them) from but when I tried to upload video (.mov file), I have an error.
Please help me to fix this problem with Carrierwave & FFmpeg or please guide to me uploading videos to my app with different ways. (Note: I am using Carrierwave for uploading images to my app, and it works perfect)
Thanks for your attention.
