}Problem with above code is that it rotates a video to left by 90 degree.
Snapshot of video given as input to above program
Snapshot of output video. It is rotated by 90 degree to left.

- Source video is taken from iphone and is of .mov format.
- Output video is being stored in .mp4 file.Can anyone please tell me why it is rotating video by 90 degree ?

Speeding up/slowing down video ffmpeg
4 avril 2021, par BahaaIddin Al SharqawiI want to change video speed using ffmpeg framework. I used this command for that :



ffmpeg -y -i /storage/extSdCard/Video/1.avi -filter_complex [0:v]fps=50.0, setpts=0.5*PTS[v];[0:a]atempo=2.0[a] -map [v] -map [a] -preset ultrafast /storage/emulated/0/VID-20170716-VidRotate1.mp4


How can I guess the duration of the resulting video after slowing down or speeding up video ?



This is my whole log in console :



ffmpeg -y -i /storage/extSdCard/Video/1.avi -filter_complex [0:v]fps=50.0, setpts=0.5*PTS[v];[0:a]atempo=2.0[a] -map [v] -map [a] -preset ultrafast /storage/emulated/0/VID-20170716-VidRotate1.mp4

FFMpeg is slow on Android [duplicate]
28 juin 2017, par Oleg FilimonovThis question already has an answer here :
I’m using this library : https://github.com/WritingMinds/ffmpeg-android
Executing this command :
ffmpeg -y -i video.mp4 -ignore_loop 0 -i overlay.gif -filter_complex `
>> "[0][1]overlay=x=mod((1080/4 + sin(t)*1080/4)\,1920):y=mod(t*300\,1080):shortest=1[res];`
>> [res][1]overlay=x=mod((200*1 + 1080/4 - sin(2*t)*1080/4)\,1920):y=mod(100 + t*300\,1080):shortest=1[res];`
>> [res][1]overlay=x=mod((200*2 + 1080/4 - sin(-90 + t/2)*1080/4)\,1920):y=mod(150 + t*250\,1080):shortest=1[res];`
>> [res][1]overlay=x=mod((200*3 + 1080/4 - sin(90 + 3*t)*1080/4)\,1920):y=mod(200 + t*100\,1080):shortest=1[res];`
>> [res][1]overlay=x=mod((200*4 + 1080/4 - sin(180 + t)*1080/4)\,1920):y=mod(t*250\,1080):shortest=1[res];`
>> [res][1]overlay=x=mod((200*5 + 1080/4 - sin(-180 + t)*1080/4)\,1920):y=mod(t*100\,1080):shortest=1[res];`
>> [res][1]overlay=x=mod((200*6 + 1080/4 - sin(2*t)*1080/4)\,1920):y=100 + mod(100 + t*300\,1080):shortest=1[res]`
>> " -map "[res]" -preset ultrafast out.mp4(Basically add a bunch of animated overlays to the video)
On PC this command takes about a second to execute (render speed is about 278 fps). But on Android device with Snapdragon 821 it takes about 10 seconds (about 30 fps).
The curious thing is that whenever command is executing on PC, CPU load is around 90%, but on Android it’s less than 1% (see screenshot : initial spike is UI stuff plus loading binaries, afterwards ffmpeg was executing until 10 second mark)
I tried executing the same command, but writing to /dev/null
instead of the file :ffmpeg -y -i video.mp4 -ignore_loop 0 -i overlay.gif -filter_complex `
>> "[0][1]overlay=x=mod((1080/4 + sin(t)*1080/4)\,1920):y=mod(t*300\,1080):shortest=1[res];`
>> [res][1]overlay=x=mod((200*1 + 1080/4 - sin(2*t)*1080/4)\,1920):y=mod(100 + t*300\,1080):shortest=1[res];`
>> [res][1]overlay=x=mod((200*2 + 1080/4 - sin(-90 + t/2)*1080/4)\,1920):y=mod(150 + t*250\,1080):shortest=1[res];`
>> [res][1]overlay=x=mod((200*3 + 1080/4 - sin(90 + 3*t)*1080/4)\,1920):y=mod(200 + t*100\,1080):shortest=1[res];`

>> [res][1]overlay=x=mod((200*6 + 1080/4 - sin(2*t)*1080/4)\,1920):y=100 + mod(100 + t*300\,1080):shortest=1[res]`
>> " -map "[res]" -preset ultrafast -f null /dev/nullThis reduced time by 3 seconds.
I also tried replacing gif overlay with png overlay, but speed didn’t improve significantly.
Here’s log of the command execution on Android :
