convert mp4 to m4a using ffmpeg in android
30 novembre 2017, par abdulrahmanI’m trying to add the ability to compress video files in my project. However, I tried to extract the Audio from the original video file using FFMPEG Library before compressing it. The command line was
-i video.mp4 -c:a aac -b:a 160k target.m4a
After the encoding was done I noticed that the output is still a video file but with a difference in the size. This brought two questions to me and I would like to know their answers.
1 - can the ".m4a" file be considered as a video file ?
2 - can I use this command line to compress video files ?
Best regards

Changing the video file attribute without modifying it ffmpeg
9 décembre 2017, par JoeSkurczysynI am using a ffmpeg script to change the creation date of the file (access to the file) in the meta tag, parameter : creation_time. It’s just that the script that I use modifies the entire video file and change the normal parameter, not only that changes the parameters of the file, it still takes several hours.
How to improve it ?
