That's what I do and it works great for me, and many others. First, find the length of the video in the below snippet:
Seems stream 0 codec frame rate differs from container frame rate: 5994.00
(5994/1) -> 29.97 (30000/1001)
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '/Users/stu/Movies/District9.mov':
Duration: 00:02:32.20, start: 0.000000, bitrate: 9808 kb/s
Stream #0.0(eng): Video: h264, yuv420p, 1920x1056, 29.97tbr, 2997tbn, 5994tbc
Stream #0.1(eng): Audio: aac, 44100 Hz, 2 channels, s16
Stream #0.2(eng): Data: tmcd / 0x64636D74
You'll should be able to consistently and safely find Duration: hh:mm:ss.nn to determine the source video clip size. Then, for each update line (CR, no LF) you can parse the text for the current time mark it is at:
frame= 84 fps= 18 q=10.0 size= 5kB time=1.68 bitrate= 26.1kbits/s
frame= 90 fps= 17 q=10.0 size= 6kB time=1.92 bitrate= 23.8kbits/s
frame= 94 fps= 16 q=10.0 size= 232kB time=2.08 bitrate= 913.0kbits/s
Just be careful to not always expect perfect output from these status lines. They can include error messages like here:
frame= 24 fps= 24 q=-1.0 size= 0kB time=1.42 bitrate= 0.3kbits/s
frame= 41 fps= 26 q=-1.0 size= 0kB time=2.41 bitrate= 0.2kbits/s
[h264 @ 0x1013000]Cannot parallelize deblocking type 1, decoding such frames in
sequential order
frame= 49 fps= 24 q=26.0 size= 4kB time=0.28 bitrate= 118.1kbits/s
frame= 56 fps= 22 q=23.0 size= 4kB time=0.56 bitrate= 62.9kbits/s
Once you have the time, it is simple math: time / duration * 100 = % done.
ffprobe -v error -select_streams v:0 -show_entries stream=nb_frames -of default=nokey=1:noprint_wrappers=1 input.mp4
N/A. See the other methods listed below.ffprobe -v error -count_frames -select_streams v:0 -show_entries stream=nb_read_frames -of default=nokey=1:noprint_wrappers=1 input.mkv
-skip_frame nokey option to only count key frames.If you do not have ffprobe you can use ffmpeg instead:
ffmpeg -i input.mkv -map 0:v:0 -c copy -f null -
frame= near the end of the console output.-discard nokey input option (before -i) to only count key frames.Ignore the MP4/M4V/M4A/MOV edit list with the -ignore_editlist 1 input option. Default is to not ignore the edit list.
-v error This hides "info" output (version info, etc) which makes parsing easier.
-count_frames Count the number of frames per stream and report it in the corresponding stream section.
-select_streams v:0 Select only the video stream.
-show_entries stream=nb_frames or -show_entries stream=nb_read_frames Show only the entry for nb_frames or nb_read_frames.
-of default=nokey=1:noprint_wrappers=1 Set output format (aka the "writer") to default, do not print the key of each field (nokey=1), and do not print the section header and footer (noprint_wrappers=1). There are shorter alternatives such as -of csv=p=0.
The well known mediainfo tool can output the number of frames:
mediainfo --Output="Video;%FrameCount%" input.avi
For MP4/M4V/M4A files.
MP4Box from gpac can show the number of frames:
MP4Box -info input.mp4
Refer to the Media Info line in the output for the video stream in question:
Media Info: Language "Undetermined (und)" - Type "vide:avc1" - 2525 samples
In this example the video stream has 2525 frames.
For MP4/M4V/M4A/MOV files.
boxdumper is a simple tool from l-smash. It will output a large amount of information. Under the stsz sample size box section refer to sample_count for the number of frames. In this example the input has 1900 video frames:
boxdumper input.mp4
...
[stsz: Sample Size Box]
position = 342641
size = 7620
version = 0
flags = 0x000000
sample_size = 0 (variable)
sample_count = 1900
stsz atom.I use the php_ffmpeg then I can get all the times and all the frames of an movie . As belows
$input_file='/home/strone/workspace/play/CI/abc.rmvb';
$ffmpegObj = new ffmpeg_movie($input_file);
echo $ffmpegObj->getDuration();
echo $ffmpegObj->getFrameCount();
And then the detail is on the page.
try this:
ffmpeg -i "path to file" -f null /dev/null 2>&1 | grep 'frame=' | cut -f 2 -d ' '
Not all formats store their frame count or total duration - and even if they do, the file might be incomplete - so ffmpeg doesn't detect either of them accurately by default.
Instead, try seeking to the end of the file and read the time, then count the current time while you go.
Alternatively, you can try AVFormatContext->nb_index_entries or the detected duration, which should work on fine at least undamaged AVI/MOV, or the library FFMS2, which is probably too slow to bother with for a progress bar.
linux
ffmpeg -i "/home/iorigins/????????????/123.mov" -f null /dev/null
ruby
result = `ffmpeg -i #{path} -f null - 2>&1`
r = result.match("frame=([0-9]+)")
p r[1]
You can use ffprobe to get frame number with the following commands
ffprobe.exe -i video_name -print_format json -loglevel fatal -show_streams -count_frames -select_streams v
which tell to print data in json format
select_streams v will tell ffprobe to just give us video stream data and if you remove it, it will give you audio information as well
and the output will be like

}
2. you can use
ffprobe -v error -show_format -show_streams video_name
which will give you stream data, if you want selected information like frame rate, use the following command
ffprobe -v error -select_streams v:0 -show_entries stream=avg_frame_rate -of default=noprint_wrappers=1:nokey=1 video_name
which give a number base on your video information, the problem is when you use this method, its possible you get a N/A as output.

Sorry for the necro answer, but maybe will need this (as I didn't found a solution for recent ffmpeg releases.
With ffmpeg 3.3.4 I found one can find with the following:
ffprobe -i video.mp4 -show_streams -hide_banner | grep "nb_frames"
At the end it will output frame count. It worked for me on videos with audio. It gives twice a "nb_frames" line, though, but the first line was the actual frame count on the videos I tested.
Try something like:
ffmpeg -i "path to file" -f null /dev/null
It writes the frame number to stderr, so you can retrieve the last frame from this.
The only accurate I've been able to do this is the following:
ffprobe -i my_video.mp4 -show_frames 2>&1|grep -c '^\[FRAME'
To make sure this works with video:
ffprobe -i my_video.mp4 -show_frames 2>&1 | grep -c media_type=video
to build on stu's answer. here's how i found the frame rate for a video from my mobile phone. i ran the following command for a while. i let the frame count get up to about ~ 10,000 before i got impatient and hit ^C:
$ ffmpeg -i 2013-07-07\ 12.00.59.mp4 -f null /dev/null 2>&1

then, i grabbed two pieces of information from that line which starts with "frame=", the frame count, 7989, and the time, 00:04:26.30. You first need to convert the time into seconds and then divide the number of frames by seconds to get "frames per second". "frames per second" is your frame rate.
$ bc -l
0*60*60 + 4*60 + 26.3
266.3
7989/(4*60+26.3)

the framerate for my video is 30 fps.

In Unix, this works like a charm:
ffmpeg -i 00000.avi -vcodec copy -acodec copy -f null /dev/null 2>&1 \
| grep 'frame=' | cut -f 2 -d ' '
Since my comment got a few upvotes, I figured I'd leave it as an answer:
ffmpeg -i 00000.avi -map 0:v:0 -c copy -f null -y /dev/null 2>&1 | grep -Eo 'frame= *[0-9]+ *' | grep -Eo '[0-9]+' | tail -1
This should be fast, since no encoding is being performed. ffmpeg will just demux the file and read (decode) the first video stream as quickly as possible. The first grep command will grab the text that shows the frame. The second grep command will grab just the number from that. The tail command will just show the final line (final frame count).
