On iOS, adding a watermark image with a .png suffix via overlay will fail.

On the iOS platform, adding a watermark image with a .png suffix through overlay will fail, and ffmpeg will prompt a decoding error: [png @ 0x1364d8b70] inflate returned error -3
Error while decoding stream #2:0: Generic error in an external library

The command line I used is as follows: ffmpeg -loop 1 -framerate 25 -i 0.jpg -i 0.mp3 -i labelImage.png -filter_complex "[0:v][2:v] overlay=x=0:y=0:shortest=1 [v]" -map "[v]" -map 1:a -c:v libx264 -c:a aac -pix_fmt yuv420p -t 6 output.mp4

The added watermark can be displayed normally on the macOS side, but not on the iOS platform. Is there any solution?
