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.m4aAfter 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

Getting this error for specific videos tried adding crf 0/22 but couldn't work through
I am not familiar with FFmpeg and its usage
Suggestion would be helpful
Thank you !

ffmpeg - when cutting video, last frame is green [on hold]
4 juillet 2016, par Mister FreshIn a php web app, the user can upload a video and cut it in samples. Php launches a shell command with shell_exec() to start ffmpeg and cut the video.
It works except that the last frame shows a green splash in the cut sample.
Server is on linux. In dev environment (mac) with latest ffmpeg, the problem cannot be reproduced.
Command is the following :
ffmpeg -i /var/www/user_dir/web/projects/127472/cuts/1146 -ss 00:00:45 -t 15 -vcodec libx264 -s 640x360 -strict experimental -v quiet -y /var/www/user_dir/web/projects/127472/cuts/sample1954_small.mp4Console output :
