FFmpeg converting image sequence to video results in blank video [closed]
(1 answer)
Closed 5 years ago.
My current project involves creating a .flv using AIR (using https://github.com/zeropointnine/leelib/tree/master/src/leelib/util/flvEncoder) - which then has to be converted into an .mp4, for which we are using ffmpeg.
The .mp4 output is the correct dimensions and duration, but blank (no images). Audio is not an issue as the original output has no audio.

Any ideas?
See the informational message:
No pixel format specified, yuv444p for H.264 encoding chosen.
Use -pix_fmt yuv420p for compatibility with outdated media players.
So, add -pix_fmt yuv420p and you should be fine.

I've tried this:
"C:\Program Files\ffmpeg-4.2.1-win64-static\bin\ffmpeg" -i %1 -i %2 -b:v 1M -y -speed 2 "%~dpn1.mp4"
"C:\Program Files\ffmpeg-4.2.1-win64-static\bin\ffmpeg" -i %1 -i %2 -pix_fmt yuv420p -vcodec libx264 -async 1 -speed 2 "%~dpn1.mp4"
Always same result. The file and quality are great, but obv since its karaoke... the lyrics need to match the timing and the converted files lyrics track is always about a full second or so ahead from when I play the original in a Karaoke program. Any ideas on what settings I could play with to help with this?
Both the original and the converted have the same play length at the end though. so the mp3 track seems to be ok.
EDIT: Added cmd output
"C:\Program Files\ffmpeg-4.2.1-win64-static\bin\ffmpeg" -i "A:\25 Karaoke\English\Linkin Park - In The End [SF Karaoke].cdg" -i "A:\25 Karaoke\English\Linkin Park - In The End [SF Karaoke].mp3" -b:v 1M -y -speed 2 "LP_inTheEnd.mp4"

Codec AVOption speed () specified for output file #0 (LP_inTheEnd.mp4) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.

that's your original command (though without the windows-specific bits) adjusted with a timestamp offset of 1 on the video and zero on the audio, so that the video should delay one second but the audio should not.
I am using FFMPEG to convert an image and an audio to a video.
I am able to achieve the final video using the following command (Attaching the output of the command too) :

Here are the respected sizes of inputs and output:
inputImage.jpg : 160kb
inputAudio.mp3 : 380.3kb
output1.mp4 : 1.3MB
The size of output video is pretty large as compared to the input audio. This is my first issue.
Secondly, as you can see, this process takes ~30sec, which is too much I think.
How do I solve this two problems?
reducing the output video file size
reducing the time this process takes.
I've gone through numerous online links, including a lot of questions on this forum for the past several hours but still not able to solve this.
Tried playing with framerate but disturbs the duration of the output video.
Can someone please help here. Let me know if any other information is needed.
1 thing that helped me reduce the size of final video from 3MB to 1.2MB was to compress the image that I am using.
Both your issues are due to the same cause. FFmpeg has generated the video by repeating the image 647 times. Your output file has 647 video frames at 21 FPS. This info is displayed in your console output.
frame= 647 fps= 21 q=28.0 Lsize= 1302kB time=00:00:23.76 bitrate= 449.0kbits/s speed=0.778x
You can optimise this by one or more of the following ways
Decrease output video resolution (-s lower-resolution)
Decrease output video bitrate (-vb lower-video-bitrate)
Decrease output FPS (-r lower-frame-rate)
My source for inputs into FFmpeg is either one AVI file or a concat of many of them. Either way my resulting timelapse file has a long tail of frames that are a repeat of a single frame. It's like a very long freeze frame is resulting on the end of my output file.
I'm on an older Mac Pro so I can't update my FFmpeg. I have a laptop that has a newer version and I get the same there as well. I'm not sure if it's because my source files are AVI or not.

I've read this thread and tried to follow it:

Am I overlooking something? I'm trying to speed up the inputs into a single file to quickly review incoming security footage. How can I do this without the super long useless tail at the end?
Use
ffmpeg -i 16460021.AVI -vf framestep=15,setpts=N/30/TB -r 30 -an out.mp4
I get an output 1/15th the length of the original. When using framestep=X, setpts should be of the form N/X/TB if you wish to avoid frame duplication. Don't use fps when compressing video duration as it uses old stream duration from before compression (a bug). Skip audio, since that will result in original length.
I wanted to create an .mp4 video with a framerate of 1 fps out of 10 images. I followed https://trac.ffmpeg.org/wiki/Slideshow and got to (my images are in the folder I am running the command from and are name img000.png, img001.png, etc.)
path_to_ffmpeg\ffmpeg.exe -framerate 1 -i img%03d.png output.mp4
However only the first image is taken to the video and it only shows one image!
After trying multiple permutations of -framerate and -r options and positions of the options, I did not recieve any better results.
Does anyone know what might have gone wrong even in this simple case? Thanks.

Older versions of VLC couldn't play videos with framerates 5 or lower. Add -r 6 to correct for that. Also, you may want to add -pix_fmt yuv420p for wide playback compatibility.
This is command i have used to download from periscope by using latest youtube-dl
youtube-dl -v periscopeurl
Then i am running this command to convert it to a proper MP4
ffmpeg -i gg.mp4 -c:v libx264 -preset veryslow -crf 18 -c:a aac -b:a 192k -pix_fmt yuv420p gg2.mp4
I am using latest youtube-dl and ffmpeg
The error i am getting is shown below
So how can i fix this error? The file can not be played properly on k lite mega codec player but it can be played on vlc player however can not go to any specific time etc. so it really needs to be properly re-encoded
