I'm trying to convert a VideoCD MPEG to MP4 using:
FFMPEG 5.1

I'm getting:

The same command using FFMPEG 4.1 works fine.

So, I'm using this code to compress my *mp4 file. I need to get lower quality and decrease bitrate:
ffmpeg -i input.mp4 -c:v libx264 output.mp4
The problem is: the last frame of footage is dropped after ffmpeg compression.
Screenshot is here: screenshot_ffmpeg_drop frame
I tried to use full preferences I need, but the problem is the same.
ffmpeg -i input.mp4 -c:v libx264 -vf scale=1280:720 -preset fast -crf 29 -r 25 -c:a copy output.mp4
logfile during ffmpeg encoding:

Use
ffmpeg -ignore_editlist 1 -i input.mp4 ... output.mp4
So I want to try and use the ffmpeg MAP command to do the following:
Merge audio and jpg
Concatenate mp4 to end
Still.jpg
audio.mp3 -> video.mp4 = output.mp4
Right now I have
/home/admin/ffmpeg/ffmpeg -i still.jpg -i audio.mp3 render1.mp4
But I want to also go ahead and add on the video.mp4 as well. I tried reading the map function but I'm so confused as to how you know how many streams a file has, etc
Heres the output of the command....note I have different file names

The resulting video runs about 18s, but seems to contain only the first frame. Changing the framerate will still end up with ~18s and only the first frame.
My expectation was: Every image would be used for one frame and the higher the framerate the shorter the video. And of course: The video should contain all images.
Is my expectation wrong? Or what could be the cause for my problem?
My command is mainly based on: https://libav.org/avconv.html#toc-image2-1
I would much rather like to delete the question.
When converting the input frames from tif (which were not accepted by avconv) to jpg, I must have hosed them up. All 447 images were actually a copy of the first one. That explains the video issues, which were no issues really.

page.open(url, function(){
setInterval(function(){
page.render('/dev/stdout');
if( frames == 0 ){
phantom.exit();
}
frames--;
}, 100);
});
Then I run this command, taken from the link above:
$ phantomjs test.js |ffmpeg -c:v png -f image2pipe -r 10 -sameq -i - -y test.mp4
Including -sameq causes an error in ffmpeg, so I took it out and ran:
$ phantomjs test.js |ffmpeg -c:v png -f image2pipe -r 10 -i - -y test.mp4
I get the following output from ffmpeg:

The output test.mp4 file is a blank 10 second video - just a black screen. From what i can tell, I am getting a pipe:: Input/output error from ffmpeg.
I am pretty new to ffmpeg and I have tried changing some parameters and video codecs in the ffmpeg call, but have not found a solution yet. Can anyone advise?
I got this to work by adding -pix_fmt yuv420p to the command:
$ phantomjs test.js | ffmpeg -y -c:v png -f image2pipe -r 10 -i - -c:v libx264 -pix_fmt yuv420p -movflags +faststart test.mp4
Otherwise the output will use a chroma subsampling type (yuv444p in this case) that is not compatible with "dumb" players like QuickTime which require yuv420p – YUV color space with 4:2:0 chroma subsampling.
Adding -movflags +faststart as an input option will allow the video to begin playing by the viewer before it is completely downloaded. Useful if the video will be viewed in a browser.
Default encoding settings for libx264 will be used in this example resulting in H.264 video. See the FFmpeg and x264 Encoding Guide for more information on controlling quality and encoding speed.
I'm using user1690179's command but the mp4 is corrupted.
I'm able to fix it with
./ffmpeg -i test.mp4 -c copy repaired.mp4
Maybe that's because of the pipe:: Input/output error?
Maybe phantomjs doesn't end gracefully?
i don't know much about phantomjs but if you plan on using regular node.js with ffmpeg and request/spawn i have done something similar. It incorporates the use of request to pipe in images for the snapshot url and ffmpeg through spawn for the mjpeg
ffmpeg jpeg stream to webm only creates a file .webm with 1 frame (snapshot) or empty .webm file (mjpeg)
I was having trouble with making webm files from jpeg snapshot and mjpeg stream.. but the answer provided took care of it.
I hope someone finds it useful as this question is pretty old... and perhaps this method is better at serving the task.
I am trying to convert a flv video to mp4 using a264, but the result video has a out of sync audio/video. The audio seems ok but the video seems slow and therefore out of sync with the audio.
Here is the command I am running:
/opt/local/bin/ffmpeg -i complaint.flv -f mp4 -vcodec libx264 -acodec aac -copyts -strict experimental -fpre /opt/local/share/ffmpeg/libx264-lossless_slow.ffpreset -ab 44k -threads 0 -crf 23 complaint.mp4
And the output:
Desktop /opt/local/bin/ffmpeg -i complaint.flv -f mp4 -vcodec libx264 -acodec aac -copyts -strict experimental -fpre /opt/local/share/ffmpeg/libx264-lossless_slow.ffpreset -ab 44k -threads 0 -crf 23 complaint.mp4

Is there something I'm missing to make sure the video and audio line up perfectly?
For those who may be trying this, I was better of recording flash in h264 right away, instead of using yuv420p for audio codec. That worked like a charm. Adding the flag -async 1 also helped.
Update: Check out this bit from the ffmpeg documentation (http://ffmpeg.org/ffmpeg.html):
-async: Audio sync method. "Stretches/squeezes" the audio stream to match the timestamps, the parameter is the maximum samples per second by which the audio is changed. -async 1 is a special case where only the start of the audio stream is corrected without any later correction. This option has been deprecated. Use the aresample audio filter instead.
You can read about the aresample filter here: http://ffmpeg.org/trac/ffmpeg/wiki/FilteringGuide
