I am using this to get the start time of the video and audio:
ffprobe -show_entries stream=start_time -i https://www.website.com/video.mp4
And the response I get is:

How can I get only the second stream, which is the audio, and without all the extra info?
So the response would just be:
start_time=9.892993
ffprobe -loglevel quiet -select_streams a -show_entries stream=start_time -of csv=p=0 -i input
Should extract the start_time for audio streams, without extra text.
Selecting specific stream is possible by replacing the -select_streams a by -select_streams N where N is the stream index (starting at 0)

I have an mp4 video (of a lecture) containing two streams, video and audio. I wanted an introduction for it (title slide of the presentation that accompanied it), so I made an mp4 out of the intro image via ffmpeg -framerate 30 -i lec01_title.jpg -t 3 -c:v libx264 -pix_fmt yuvj420p -vf "scale=1920:1080" lec01_title.mp4 -f lavfi -i anullsrc -c:a aac. When I try to concat the files using the demuxer, it doesn't work. First, I try to verify that the properties (encoding, etc.) of the two videos are the same.
If I run ffmpeg -i lec01.mp4, I get:

I tried to verify that the properties of the two videos match via ffprobe -select_streams a:0 -show_entries stream=codec_name,channels -of default=nw=1:nk=1 -v 0 lec01.mp4 and ffprobe -select_streams v:0 -show_entries stream=codec_name,width,height,r_frame_rate,pix_fmt -of default=nw=1:nk=1 -v 0 lec01.mp4, and they do. The first command gives me
aac
2
and the second command gives me
h264
1920
1080
yuvj420p
30/1
for both videos.
Now, if I have a file called lec01.txt containing:
file 'lec01_title.mp4'
file 'lec01.mp4'
when I run ffmpeg -f concat -i lec01.txt -c copy output.mp4, the resulting video is of length 04:44:04 (four hours, when my two input videos were 3 seconds and 45:24 minutes respectively), and it only shows the title slide for that entire duration.
Furthermore, when I run this concat command, I get the following message repeated many times: [mp4 # 0x7f82b9013b80] Non-monotonous DTS in output stream 0:1; previous: 133290, current: 133120; changing to 133291. This may result in incorrect timestamps in the output file.
I'm missing something. When I look up this error, it seems to be something related to the decoding time stamps (DTS) or presentation time stamps. Anyone know what I'm doing wrong and how to fix? Thank you for your help!
Edit:
It appears to work if I re-encode via ffmpeg -i lec01_title.mp4 -i lec01.mp4 -filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa]" -map "[outv]" -map "[outa]" output.mp4, but I'd like to avoid doing this since I have tons of videos I need to do this for.
How can i fix this ;( help me....
it works well if i tpye only "'ffmpeg -i ' + video_path + ' -q:v 2 -f image2 ' + frame_path + '\image_%6d.jpg'" on prompt with specific path name.
but it doesn't work in .py (i used code in .py-> os.system('ffmpeg -i ' + video_path + ' -q:v 2 -f image2 ' + frame_path + '\image_%6d.jpg')

Make use of helpful (& more secure) built-in packages/functions:
from os import path
import subprocess as sp
sp.run(['ffmpeg','-i', video_path,
'-q:v','2','-f','image2',
path.join(frame_path,'image_%6d.jpg')])
I suspect your call went nuts because of unescaped backslashes in the file paths. subprocess.run essentially avoids that nastiness from making a system call.
I uses the following command that can extract the mpeg4 raw video fileļ¼
ffmpeg -i D:\mp4v-mp4\test\360.mov -vcodec copy -an -f rawvideo D:\mp4v-mp4\test\360CmdSplit_std.dat
but how can I convert the rawvideo file back to a playable mp4 file.
I have tried the follow cmd, but failed:
ffmpeg -y -f m4v -i D:\mp4v-mp4\test\360CmdSplit_std1.dat -vcodec copy D:\mp4v-mp4\test\tmp360.mp4
the first cmd(extract the raw mp4v video) is success,logs:

output terminal says:
Invalid file index 1 in filtergraph description fps=25,scale=800:600:flags=lanczos[x],[x][1:v]paletteuse.
You forgot a second -i before palette.png.
Each input requires its own -i option.
Am trying to add text on video using ffmpeg. Everything works well if there is no spacing in the words. Here is my code
$text = "Robert Tamunoemi";
$cmd = 'ffmpeg -i '.$videoPath.' -vcodec libx264 -f mp4 -vf drawtext="fontfile=fonts/futura-normal.ttf:text="'.$text.'":fontcolor=black#1.0:fontsize=14:x=00: y=40" -preset medium videos/birds.mp4';
shell_exec($cmd.' 2> log.txt');
Here is the output from ffmpeg log
