I want to obtain a different raw video for each frame of an MP4 file.
My instruction works in an old version of ffmpeg but not in the new one.
In the mp4 file there are 137 frames. It is checked. The versions are installed on different machines.
Versions 2.8.15:
$ ffmpeg -i ./video.mp4 -vf fps=30 -vframes 137 -vcodec rawvideo -s '1920x1080' -pix_fmt gray -threads 0 frame%08d.raw

In the latest version, I expect 137 files but the amount is 136.
The old version did not have support for edit lists. Technically, some frames are not meant for presentation but only as reference, but since you want all frames, use
ffmpeg -ignore_editlist 1 -i ./video.mp4 -vsync 0 -c:v rawvideo -s '1920x1080' -pix_fmt gray frame%08d.raw

I recorded a RTSP stream(4K) via VLC for about an hour and something odd happened.
The file size is 6.6 GB, but the video length is only 12 minutes long.
When I play it on VLC, the progress bar reaches the end, but the video still plays continuously.
Add to that, its FPS is 213, although playing speed is 30 FPS.
I tried below commands, but couldn't fix the issue.
$ ffmpeg -i <INPUT.mp4> -filter:v fps=fps=30 <OUTPUT.mp4>
// Only returns a 12 minutes long video
$ ffmpeg -vsync drop -i <INPUT.mp4> -map 0:v -vcodec copy output.mp4
// Crashes immediately

Although I couldn't restore the full file due to corrupted frames, I want to share the progress.
MP4Box supports changing the framerate without re-encoding
$ MP4Box -single 1 -raw 1 <INPUT_MP4_FILE>
It will return two files, <INPUT_MP4_FILE>_track1.mp4 and <INPUT_MP4_FILE>_track1.h264.
<INPUT_MP4_FILE>_track1.mp4 is a file with the correct fps and duration.
For my video, the file stops at 54:17 (the total length is 1:23:17),and I believe it's due to corrupted frames.
Reference
From what I gather, using ffmpeg to fully decode a video should give me an accurate duration. If I use:
ffmpeg -i my_vid.mov -f null -
for a particular video, I get an output of:
...
frame= 901 fps=0.0 q=-0.0 Lsize=N/A time=00:00:30.52 bitrate=N/A speed= 247x
...
But when I run the following command to extract a frame near the end, it fails:
ffmpeg -i my_vid.mov -ss 00:00:30.450 -q:v 2 -vframes 1 test_frame.jpg
outputs:
Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)
Backing up to 00:00:30.000 with the ffmpeg command does get me a frame, however, and any time before that works as expected also. It seems like I should be able to get frames up to 00:00:30.520, though. What could be wrong here? Am I misreading the duration output?
Here is the full output I get from the frame extraction command:
> ffmpeg -ss 00:00:30.450 -i file_example_MOV_640_800kB.mov -q:v 2 -vframes 1 test_frame.jpg

With an output seek, FFmpeg waits for the first keyframe after the seek point to start emitting frames.
Use an input seek,
ffmpeg -ss 00:00:30.450 -i my_vid.mov -q:v 2 -vframes 1 test_frame.jpg
To get the very last frame from a MOV/MP4 more generically, use
ffmpeg -sseof -3 -i my_vid.mov -q:v 2 -update 1 test_frame.jpg
When I try cutting a video, it outputs an empty stream (262 byte video with 0s duration). Would appreciate any insight, thanks.
Command used:
ffmpeg -i /path/to/long/video.mp4 -ss 37.69 -t 4.96 -c copy /path/to/short/video.mp4
However, when I the following (more inaccurate) command, it outputs a video. This video also has some problems, as the last frame is repeated several times, making the video one second longer (with a frozen image for one second).
ffmpeg -ss 37.69 -i /path/to/long/video.mp4 -t 4.96 -c copy /path/to/short/video.mp4

Two issues:
3.4 is old. Update to a recent build before doing anything else. For Linux you can download or compile.
Cuts are not guaranteed to be accurate when using stream copy mode (-c copy) with H.264 and other similar formats because it will need to include all of the other frames necessary to decode the segment. So either cut on keyframes or re-encode by removing -c copy.
When I extract all frames from a video, FFmpeg lose one frame. I tried multiple options, like adding more parameters to the function, but none of them worked.

I have a problem with ffmpeg,I try to add a png files over a video i found how to add just I want this png file have some opacity
I tryed this line
ffmpeg -n -i video.mp4 -i logo.png -filter_complex "setsar=sar=1;blend=all_mode='overlay':all_opacity=0.7" -movflags +faststart tmb/video.mp4
with this line ffmpeg return this error
