ffmpeg: trsfer a h264 video to a series of jpg failed - encoding

me and a partner are trying to transfer a h264 video to a series of images using ffmpeg with the following command line:
ffmpeg -i input.h264 -qscale:v 2 output_%03d.jpg
The input.h264 can be played perfectly on vlc, but the images generated by ffmpeg are just all black. The message in the console are below:

However, this command works perfectly fine on random h264 videoes on the internet, so I guess there may be something wrong with our h264 video, but the weird thing is that it can be played by vlc player just fine...
Any idea what the problem can be? Any help will be appreciated!


The beginning of your file seems to be broken. How was it generated? Try
ffplay -flags output_corrupt input.h264

ffmpeg seems to output a video with a wrong codec?

I´m using ffmpeg with flutter and I create a video from a lot of images. The problem: ffmpeg seems to not create a video with a right codec or something else.... please check my description below for concrete informations.
First the code parts:
Creating video from images
-r $settings_fps -i $tempPath/img%04d.jpg -vcodec libx264 -y -an -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -shortest $tempPath/$videoFileName.mp4
Adding audio to the created video
-i ${finalSong.path} -i $videoPath -c:a aac -shortest $tempPath/$newVideoFileName.mp4
This is my video output from console on creating this video:

flutter: Speichern mit GallerySaver nicht erfolgreich
In general the created video works, but: If i try to save it as video with flutter gallery_saver to the device, this video will not saved. Other videos for example works well. But not the created with ffmpeg.
Can you find any reason for this in the ffmpeg output log? Thank you!

Videos for web playback usually require chroma sampling to be 4:2:0. FFmpeg, by default, will try to preserve the source sampling scheme, so your output is 4:2:2 (see yuvj422p in the output stream).
Use for step 1,
-r $settings_fps -i $tempPath/img%04d.jpg -vcodec libx264 -y -an -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -pix_fmt yuv420p $tempPath/$videoFileName.mp4
And in step 2, avoid re-encoding video
-i ${finalSong.path} -i $videoPath -c:v copy -c:a aac -shortest $tempPath/$newVideoFileName.mp4

Why are these two IMAP Search results different from one another?

I'm using imaplib, and trying to fetch emails with a certain subject header value.
My code:
res, tmp = self.mail.uid('search', None, 'HEADER Subject "SUBJECT_HERE"')
print(tmp)
print(res)
print("test 2 goes:")
rr, tt = self.mail.search(None, 'HEADER Subject "SUBJECT_HERE"')
print(tt)
print(rr)

I thought that those two commands result in the same results.
But as shown above, those two fetch different emails.
What is the difference??

One (SEARCH) returns message sequence numbers (MSN), which are numbered from 1 to N and change as messages are added and deleted. A message that is number 5 now could be number 4 tomorrow if you delete a message before it.
The other (UID SEARCH) returns UIDs, which do not change as messages are deleted. They're two completely different set of identifiers. A message with UID 5 will remain UID 5 until it is deleted it (or moved, etc.).
The UID will never reused in that incarnation of a folder. If the folder is deleted and recreated, or the mail server is rebuilt, the folder's UIDVALIDITY should change so you can detect that your cache is no longer valid.

!dumpheap -min for strings does not work as expected [duplicate]

The documentation said it's used for limit the size of the output object, but based on my test, it's not what I expected:
0:000> !dumpheap -mt 000007fee12406a8 -max 400 -min 399
Address MT Size
000000000d1dc1f8 000007fee12406a8 936
000000000d62bed8 000007fee12406a8 1016
000000000d630d00 000007fee12406a8 984
000000000d633aa8 000007fee12406a8 984
000000000d65f368 000007fee12406a8 952
000000000d685ff0 000007fee12406a8 952
000000000d6b2150 000007fee12406a8 952
So how to understand the -min and -max options?

WinDbg's default number format is hexadecimal. 0x400 is 1024 and 0x399 is 921, that explains the output. If you want decimal numbers, use the 0n prefix, e.g. 0n400 and 0n399.

Connecting points in qqplot in MATLAB

I am trying to plot a qqplot graph for different data samples. I am able to draw it for individual data samples. How can I draw a qqplot graph for multiple data samples? Also, I want to connect all the points with a line and color for each data set to differentiate them. How can I achieve this in MATLAB?
I am getting the output as below:
I am trying to get the output in the below format(qqlplot for 4 samples).
I am loading the data from csv file into matlab.
Next, drawing the graph using the function qqplot(1mb);
