Reported by: diicepoo Owned by:

Analyzed by developer: no


I use release: 4.2.2 (static)

Final code will be on "Amazon AWS lambda"
Goal: use a url stream and add watermak

Link to video:
Link to Watermak:

% ./ffmpeg -i "" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4

return "Segmentation fault"

% ./ffmpeg -i "" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4

work (but not watermak )

% ./ffmpeg -i "./519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4

work (but not with stream )

Thanks you very much !
