ffmpeg complex filter - multiple crops on black background
31 octobre 2017, par Kevin O'HaraWe are attempting to process a video file by cropping it into several pieces and arranging it on a black background which is exactly 1920x1080. The following command runs but it never completes and we have to kill the process.
Is there something wrong with how we’re trying to do this ?
ffmpeg -i in.mov -y -filter_complex "\
color=s=1920x1080:c=black[bg];\
[0:v]crop=w=1920:h=ih:x=0:y=0[crop1];\
[0:v]crop=w=iw-1920:h=ih:x=1920:y=0[crop2];\
[bg][crop1]overlay=x=0:y=0[out1];\
[out1][crop2]overlay=x=0:y=h[final]" \
-map [final] out.mov -
FFmpeg and Android encoding issue
4 décembre 2012, par bruxI compiled ffmpeg for Android. The executable works from the device terminal and I can do normal video operations. I am trying to join 2 mpeg files captured using the camera at the command line on the device.
First I Capture 2 videos using the camera and save to sdcard, one.mpeg and two.mpeg. Then I do :
ffmpeg -i one.mpeg onenew.mpeg
ffmpeg -i twompg.mpeg twonew.mpeg(if i dont do the above 2 commands then it doesnt work at all)
cat onenew.mpeg twonew.mpeg > joined.mpeg
ffmpeg -i joined.mpeg -acodec copy -vcodec copy final.mpegThe output (final.mpeg) doesnt play on the device but if i copy to my linux desktop it opens up and plays fine. I tested final.mpeg on a 2.3.3 device and a 2.3.6 device.
Anyone know why the device would fail to play the video file ?
UPDATE
My friend tested the video on a device running 3.0, the default player never played the video however 'moboplayer' did, I need it to play on the default player though. -
How to combine audio and output with python
27 octobre 2023, par Jojo MomoThis question was asked a few times a couple of years ago, but none of the solutions seem to work.


This code creates a video
output.mp4
which is the same asvideo.mp4
, but it doesn't have any sound fromaudio.mp3
even whenvideo.mp4
has sound in the first place.

import moviepy.editor as mp

audio = mp.AudioFileClip("audio_output/audio.mp3")
video1 = mp.VideoFileClip("video.mp4")
final = video1.set_audio(audio)

final.write_videofile("output.mp4")



If anyone knows of alternative methods without using moviepy please let me know ! (Or if you know why this isn't working)
