FFMPEG, the penultimate image from the .txt file doesn't show in the video
25 octobre 2019, par ArmKhI’m trying to create a video from the images using
ffmeg
. Actually, the creating of the video works but there is a small problem. I have a text file with the names of the images (paths) which I’m using in the video. The file looks like thisfile 'image1.jpg'
file 'image2.jpg'
file 'image3.jpg'
file 'image4.jpg'
file 'image5.jpg'And the ffmeg command is following
ffmpeg -y -r 1/5 -f concat -safe 0 -i imagenames.txt -i some_audio.mp3 -c:v libx264 -vf fps=30 -pix_fmt yuv420p -t 30 output.mp4
This video should keep the frame on every image for 5 seconds. But the problem is the penultimate image
( image4 in this case )
is not being shown in the video. So, it keeps onimage3
10 seconds and moves toimage5
So, the video in seconds looks like this
[image1] -> [image2] -> [image3] -> [image4] -> [image5]
5sec 5sec 10sec 0sec 5secAnd the problem is not with the
image4
exactly. In case of swappingimage3
andimage4
, the video will skipimage3
[image1] -> [image2] -> [image4] -> [image3] -> [image5]
5sec 5sec 10sec 0sec 5secHope you’ll have any suggestions to fix this issue

ffprobe does not show packet size of a mpeg transport stream as 188 bytes
16 octobre 2015, par CompNetI created a transport stream from a
H.264
encoded file using the followingffmpeg
command :ffmpeg -i encoded.mp4 -c copy -map 0 -vbsf h264_mp4toannexb mpegts sample.ts
Now I want to check the frames and packets within the transport stream. I used
ffprobe -show_frames
which shows the frame details for audio and video frames. But I’m confused about the
pkt_size
field. Is it the actual frame size of each elementary stream of audio and video (I/B/P frames) ?Also, when I run
ffprobe -show_packets
is it supposed to give each packet details in the transport stream ? Because the
size
field of each packet is not 188 bytes, rather it is same as thepkt_size
I got with-show_frames
.Could someone please explain why the size in
-show_packets
of transport stream is not 188 bytes ? Did I do anything wrong while multiplexingmp4
toTS
?
