I'm trying to use ffmpeg on Synology NAS with DSM 6.2 to create waveform of my mp4 files. 



ffmpeg -i aaa.mp4 -lavfi showwavespic=split_channels=1:s=1024x800 waveform.png



[NULL @ 0x24271e0] Unable to find a suitable output format for 'waveform.png' waveform.png: Invalid argument


but 



ffmpeg -i aaa.mp4 -lavfi showwavespic=split_channels=1:s=1024x800 waveform.avi


working well and I can see wave while playing waveform.avi
