iOS crashes on _flutterFFmpeg.execute(_command) #220

Closed frankyvij closed 4 years ago

frankyvij commented 4 years ago

Description Application crashes both on the simulator and physical device as soon as the execute function is called.

I am running the following command: ffmpeg command: -i "/Users/shauryanvij/Library/Developer/CoreSimulator/Devices/27F7D20F-A571-4F80-9BE1-61B4A0B3096B/data/Containers/Data/Application/0DA9559D-13F1-4178-AFA8-DFCF20928B92/tmp/trim.9AFA2179-C6CC-4E26-9CC7-91F81A23A4FC.MOV" -ss 0:00:00.000000 -t 0:00:15.000000 -c:v libx264 -crf 19 -level 3.1 -preset slow -tune film -filter:v scale=trunc(oh*a/2)2:480 -sws_flags lanczos -c:a copy "/Users/shauryanvij/Library/Developer/CoreSimulator/Devices/27F7D20F-A571-4F80-9BE1-61B4A0B3096B/data/Containers/Data/Application/0DA9559D-13F1-4178-AFA8-DFCF20928B92/Documents/Trimmer/trim_trimmed:Oct27,2020-15:57:18.mp4"

I have tried to simplify the command above, but it still crashes. ffmpeg command: -i "/Users/shauryanvij/Library/Developer/CoreSimulator/Devices/27F7D20F-A571-4F80-9BE1-61B4A0B3096B/data/Containers/Data/Application/0DA9559D-13F1-4178-AFA8-DFCF20928B92/tmp/trim.9AFA2179-C6CC-4E26-9CC7-91F81A23A4FC.MOV" -ss 0:00:00.000000 -t 0:00:15.000000 -c:v copy -c:a copy "/Users/shauryanvij/Library/Developer/CoreSimulator/Devices/27F7D20F-A571-4F80-9BE1-61B4A0B3096B/data/Containers/Data/Application/0DA9559D-13F1-4178-AFA8-DFCF20928B92/Documents/Trimmer/trim_trimmed:Oct27,2020-15:57:18.mp4"

Expected behavior Application should not crash, and FFMpeg should encode the video properly.

Current behavior Application is crashing.

Also, please note that the code implemented works perfectly fine in Android.

Can you please run your app in Xcode and show us where it crashes exactly.

I am so sorry! The issue was caused by another package that would generate the thumbnail. I have fixed the problem. I will now close the issue! Thank you.
