FFmpeg Error "No such filter : 'libvmaf' Mac
4 janvier 2021, par ringola27I want to use FFmpeg to calculate PSNR for video sequences.
At first I installed libvmaf with the instruction from here and here. I installed ffmpeg like here. I tried for a test :



ffmpeg -i output4.mpg -i output1.mpg -lavfi libvmaf -f null -




But I get an Error (below). I think I could solve it with
./configure --enable-libvmaf --enable-version3
or./configure --enable-libvmaf
but unfortunately I can not run it (I don't know how).


I hope anyone can help me to solve this problem.

The SSIM values calculated using FFMPEG are not what I expected
18 mai 2020, par fd-alexerI'm trying to encode an m2ts (MPEG-2 Transport Stream) file to mp4 (H.264) and get the ssim value.

I did get some SSIM values, but the results were contrary to my expectations.


Are there wrong command options for ffmpeg ?



Encoding and SSIM calculation commands



# encode
$ ffmpeg -hide_banner -fflags +discardcorrupt -i input.m2ts \
 -c:v libx264 -crf <crf> -preset:v medium \
 -c:a copy -bsf:a aac_adtstoasc \
 output_ff_crf-<crf>.mp4

# calculate ssim
$ ffmpeg -hide_banner -i <a> -i <b> \
 -lavfi "[0:v]settb=AVTB,setpts=PTS-STARTPTS[main];[1:v]settb=AVTB,setpts=PTS-STARTPTS[ref];[main][ref]ssim" \
 -f null -
</b></a></crf></crf>



The results of the SSIM



(a) A=input.m2ts, B=input.m2ts, ssim=0.973266
(b) A=input.m2ts, B=output_ff_crf-0.mp4, ssim=0.813347
(c) A=input.m2ts, B=output_ff_crf-30.mp4, ssim=0.819897
(d) A=output_ff_crf-0.mp4, B=output_ff_crf-0.mp4, ssim=1.000000
(e) A=output_ff_crf-0.mp4, B=output_ff_crf-30.mp4, ssim=0.972911




- 

- (d)(e) : These are what I expected.
- (a) : The files are the same, but ssim≠1.
- (b)(c) : SSIMs with CRF=0 and CRF=30 have almost the same value, although the image quality is different.









In the case of HandBrakeCLI



To determine if there was a problem with input.m2ts, I ran HandBrakeCLI with almost the same parameters as ffmpeg.



# encode
HandBrakeCLI --verbose --format av_mp4 --encoder x264 --quality <crf> --x264-preset medium \
 --aencoder copy \
 --input input.m2ts --output output_hb_crf-<crf>.mp4

# calculate ssim (same as ffmpeg)
$ ffmpeg -hide_banner -i <a> -i <b> \
 -lavfi "[0:v]settb=AVTB,setpts=PTS-STARTPTS[main];[1:v]settb=AVTB,setpts=PTS-STARTPTS[ref];[main][ref]ssim" \
 -f null -
</b></a></crf></crf>



(b') A=input.m2ts, B=output_hb_crf-0.mp4, ssim=0.999999
(c') A=input.m2ts, B=output_hb_crf-30.mp4, ssim=0.972886
(d') A=output_hb_crf-0.mp4, B=output_hb_crf-0.mp4, ssim=1.000000
(e') A=output_hb_crf-0.mp4, B=output_hb_crf-30.mp4, ssim=0.972886




It's all as I expected. (although A is not ssim=1.0) 
Therefore, I don't see a problem with input.m2ts.

FFMPEG Add thumbnail to video [duplicate]
18 mai 2020, par james-normanadd a thumbnail to my video file. I have the code that I have compiled with the help of other people from StackOverflow and I have one bit left to finish it off and that is to add a line of code to add video thumbnail.



you will see some weird text in command like targggget these are words that get replaced by the software so ignore it.

app.path\ffmpeg gets replaced with file-path/ffmpeg

targgggett\targ3et.mp4 file-path/xx.mp4

targgggett\targetimgee - output is example C :\Users\username\Desktop\vidz\New folder\images\demo.png


"app.path\ffmpeg" -y -i "targgggett\targ3et.mp4" -loop 1 -framerate 30000/1001 -t 5 -i "targgggett\targetimgee" -t 0.5 -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=44100 -filter_complex "[0:a]atempo=1.0,pan=stereo|c0code>



i want to add a video thumbnail using targgggett\targetimgee and set video thumbnail only



"app.path\ffmpeg" -y -i "targgggett\targ3et.mp4" -loop 1 -framerate 30000/1001 -t 5 -i "targgggett\targetimgee" -t 0.5 -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=44100 -filter_complex "[0:a]atempo=1.0,pan=stereo|c0code>
