Hello,
Summary of bug:
It appears that newer versions of FFmpeg do not allow PNG files to be
specified within the -vf (video filter command).
How to reproduce:
ffmpeg -y -i big_buck_bunny_1080p_h264.mov \
-b:v 3000k -vcodec h264 -t 30 -acodec aac -strict experimental -ab 128k \
-vf "movie='sample-128.png' [wm]; [in] [wm] overlay=W-w-10:H-h-10 [out]" \
"outtest.mp4"
I was able to reproduce this with:
FFmpeg 2.4
FFmpeg 2.4.1
ffmpeg version N-40926-g303fc9b
The exact same command works when replacing the PNG file with a JPEG file.
