How to split a mp4 file into multiple .m4s chunks with one init.mp4 file
29 novembre 2018, par JAVA CoderI am trying to split one audio.mp4 into multiple chunks(each of 10 seconds) with file format of .m4s or .mpd and one init.mp4 .
1>I have successfully made chunks of 10 secs with one m3u8 file by this command-
ffmpeg -i song.mp3 -c:a aac -b:a 64k -vn -hls_time 10 -hls_list_size 0 abc.m3u8
2>Tried this command also
MP4Box -dash 10000 -frag 1000 -rap -segment-name myDash -subsegs-per-sidx 5 -url-template test.mp4
But not able to make .m4s chunks with one init.mp4.

ffmpeg converting JPG slideshow to MKV
17 décembre 2018, par pholI am trying to convert a set of jpg files to a slideshow with varying durations using ffconcat
output.txt contents :
ffconcat version 1.0
file slide_0001.jpg
duration 0.163
file slide_0002.jpg
duration 0.533
file slide_0003.jpg
duration 1.067
file slide_0004.jpg
duration 0.533
file slide_0005.jpg
etc.FFmpeg command :
ffmpeg -i output.txt output.mkv
I also tried :
ffmpeg -i output.txt -c:v copy output.mkv
However, when converting, the colours of the images become skewed.
White becomes pink / purple and dark green becomes light green.
The same happens when choosing different codecs and containers.
Is there a way to solve this ?EDIT :
I performed the same conversion again. I attached the log output as requested.
However, in the meantime I have figured out that converting without ffconcat duration and then altering timecodes with mp4fpsmod is more efficient in terms of storage (3 vs 40 MB) and gives less issues in different players. The result is nonetheless the same : colours are still wrong, both on my workstation (Ubuntu 18.04) and laptop (macOS Mojave).I tried to alter things with
pix_fmt
and-vf format
as can be seen in the second log output. This did not solve the problem.Background info :
The input jpg files are from a lecture recording made with MediaSite, which has both a video stream for the room as well as this slideshow stream for the slides.Example of input :
Example of output :

ffmpeg converting JPG slideshow to H264
22 décembre 2018, par pholI am trying to convert a set of jpg files to a slideshow with varying durations using ffconcat
output.txt contents :
ffconcat version 1.0
file slide_0001.jpg
duration 0.163
file slide_0002.jpg
duration 0.533
file slide_0003.jpg
duration 1.067
file slide_0004.jpg
duration 0.533
file slide_0005.jpg
etc.FFmpeg command :
ffmpeg -i output.txt output.mkv
I also tried :
ffmpeg -i output.txt -c:v copy output.mkv
However, when converting, the colours of the images become skewed.
White becomes pink / purple and dark green becomes light green.
The same happens when choosing different codecs and containers.
Is there a way to solve this ?EDIT :
I performed the same conversion again. I attached the log output as requested.
However, in the meantime I have figured out that converting without ffconcat duration and then altering timecodes with mp4fpsmod is more efficient in terms of storage (3 vs 40 MB) and gives less issues in different players. The result is nonetheless the same : colours are still wrong, both on my workstation (Ubuntu 18.04) and laptop (macOS Mojave).I tried to alter things with
pix_fmt
and-vf format
