I am trying to extract images from video using ffmpeg:
ffmpeg -i sample.mp4 -vf fps=1/30 img%03d.jpg
But I am getting this following error

image2: Invalid argument
The final out required is I need to extract image at fps 30.
For extracting images from a video:
ffmpeg -i sample.mp4 -r 30 -s WxH -f image2 image%03d.jpg
The -r flag defines extracted image frames per second. It will output them in files named image001.jpeg, image002.jpeg, etc. The optional -s flag will rescale images to fit the new WxH values.
If you want to extract just a limited number of frames, you can use the above command in combination with the -vframes or -t option, or in combination with -ss to start extracting from a certain point in time.
For more informations, check documentation.

I'm trying to concatenate video and audio files, filling space between them with black frames or silence correspondingly.
I use the following command:
ffmpeg -i test/v/1.mkv -i test/v/2.mkv -i test/v/1.mka -i test/v/2.mka -filter_complex 'color=c=black:s=640x480:d=12ms[black0];
color=c=black:s=640x480:d=207725ms[black2];
aevalsrc=0:d=257495ms[silence1];
aevalsrc=0:d=114833ms[silence2];
[black0][0][black2][1][2][silence1][3][silence2]concat=n=8:v=1:a=1[v_out][a_out]' \
-map [v_out] -map [a_out] -c:v libvpx -c:a libopus result.webm
But I get the following error:
Stream specifier '' in filtergraph description matches no streams.

What I'm doing wrong? Help please.
I followed Im getting error "deprecated pixel format used, make sure you did set range correctly using ffmpeg".. can someone check my code below? to save a frame from a video but the saved frame is of timestamp 00:00:00 instead of the given timestamp

FFmpeg resets output timestamps to start from zero, unless the user expressly adds flags to override it. So, nothing wrong or unexpected here.
I see that there are a few questions on this subject but I am still getting errors. All I want to do is convert videos in my library to HEVC so they take up less space.
I've tried this:
ffmpeg -i input.mp4 -c:v libx265 output.mp4
ffmpeg seems to take a long time and the output seems to be about the right size. The video will play with VLC but the icon is weird and when I try to open it with QuickTime, I get the error: 'The document “output.mov” could not be opened. The file isn’t compatible with QuickTime Player.'
I don't want to change any of the fancy settings. I just want the files to take up less space and with minimal or no quality loss.
Thanks!
EDIT:
Having trouble keeping the time stamp that I put into the videos.
Originally I was using exiftool in terminal. But, sometimes that doesn’t work with videos, so I would airdrop them to my iPhone, use an app called Metapho to change the dates, and then airdrop them back. Exiftool was create but sometimes I just wouldn’t work. It would change the date to something like 1109212 Aug 2nd. Weird. Bottom line is that when I do these conversions, I really don’t want lose the time stamps in them.

This answer was posted (under the CC BY-SA 4.0 license) as a comment by Gyan to the question Convert videos from .264 to .265 (HEVC) with ffmpeg.
Run this command for x265 convertation:
ffmpeg -i input.mp4 -c:v libx265 -vtag hvc1 output.mp4
Convert 4k to 1080 (no change in codec)
ffmpeg -i input4kvid.mp4 -vf scale=1920:1080 -c:a copy output1080vid.mp4
Convert h.264 to h.265 (no change in resolution)
ffmpeg -i input.mp4 -c:v libx265 -vtag hvc1 -c:a copy output.mp4
Convert 4k(h.264) to 1080(h.265)
Downscaling + Change in compression codec
ffmpeg -i input.mp4 -c:v libx265 -vtag hvc1 -vf scale=1920:1080 -crf 20 -c:a copy output.mp4
Options Explained
-i input file name or file path
-c:v libx265 -vtag hvc1 selecting compression. Default is libx264
-vf scale=1920:1080 specifying output resolution
-c:a copy copy audio as it is without any compression
-preset slow ask compression algorithm to take more time & look for more areas for compression. Default is medium. Other options are faster, fast, medium, slow, slower
-crf 20 Compression quality
-crf 0 high-quality, low compression, large file
-crf 23 default
-crf 51 low-quality, high compression, small file
-vtag hvc1 use codec hvc1 (a.k.a. HEVC or h.265) during conversion.
If -vtag isn't specified (like in the first snippet), it will then use the codec used in the src file.
If you have NVIDIA GPU, you can use hevc_nvenc for the encoder parameter which should be faster than a CPU encoder.
ffmpeg -i input.mp4 -c:v hevc_nvenc -rc vbr_hq -cq 18 -b:v 0k -2pass 0 output.mp4
However, note that hardware encoded files aren't as optimized as CPU encoded
for mobile phone users it's better to use the scale of 1080*1920.
ffmpeg -i input4kvid.mp4 -vf scale=1080:1920 -c:a copy output1080vid.mp4
I am using this code to apply watermark on linux server;
-i input.mp4 logo.png -filter_complex 'overlay=main_w-overlay_w-10:main_h-overlay_h-10' output.mp4
so ended-up with this error;
Please use -b:a or -b:v, -b is ambiguous
Cannot find a matching stream for unlabeled input pad 1 on filter Parsed_overlay_0
Full error;

Your image isn't presented as an input so ffmpeg treats it as the first output, and output.mp4 as the 2nd output. The filter_complex only sees the video as an input.
Start your command like this
ffmpeg -i input.mp4 -i logo.png
I use this simple script to convert video to images using ffmpeg, but frame rate is fixed, how can I determine it automatically?
FRAME_RATE="30"
SEPARATOR='/'
VIDEO_PATH=$1
VIDEO_BASE_DIR=`dirname $1`
FRAMES_DIR=$VIDEO_BASE_DIR$SEPARATOR"Frames"
rm -rf $FRAMES_DIR
mkdir $FRAMES_DIR
#Convert video to images
./ffmpeg -r $FRAME_RATE -i $VIDEO_PATH $FRAMES_DIR$SEPARATOR"image%d.png"
UPDATE:
By ffprobe I checked that my 1st video frame rate is 30.
Also results are the same (339 frames are produced) even I reduce frame rate, so -r option doesn't work or work in some other way?
These command give the same result:
./ffmpeg -r 10 -i $VIDEO_PATH $FRAMES_DIR$SEPARATOR"image%d"$EXTENSION
./ffmpeg -r 30 -i $VIDEO_PATH $FRAMES_DIR$SEPARATOR"image%d"$EXTENSION
./ffmpeg -i $VIDEO_PATH $FRAMES_DIR$SEPARATOR"image%d"$EXTENSION

ffprobe -show_streams "video" 2>&1 | \
grep fps | \
awk '{split($0,a,"fps")}END{print a[1]}' | \
awk '{print $NF}'
Some time ago I wrote an article about generating ffmpeg previews from videos which is maybe similar to what you're trying to do. I had to count total number of frames in a video:
See https://www.binpress.com/tutorial/how-to-generate-video-previews-with-ffmpeg/138
What about
./ffmpeg -i input_file 2>&1 | sed -n "s/.*, \(.*\) tbr.*/\1/p"
ON windows 10,
ffmpeg -i <input video file>
The last portion will show fps info. Please check the line beginning with "Stream...."
The following video file is encoded in 60 fps .
