Hi, I hit the same problem, which is that synfig is passing options to ffmpeg which ffmpeg doesn't understand, namely -loop -hq -title blah.
Probably a previous version of ffmpeg understood these options, but the latest one appears not to. The proper fix is therefore to update synfig to use the correct options for ffmpeg. In the meantime, I wrote a python script called ffmpeg which you could keep somewhere on your path ahead of /usr/bin. It simply strips out the bogus options and invokes the real ffmpeg. Yes I know it's a bit of a dodgy solution, but needs must ... cheers, Simon
#!/usr/bin/python # ffmpeg - a work-around for synfig to filter out the bogus arguments that # get passed in when rendering import os import sys original_args = sys.argv new_args = [] #print original_args while len(original_args) > 0: arg = original_args.pop(0) if arg == "-loop" or arg == "-hq": pass elif arg == "-title": original_args.pop(0) else: new_args.append(arg) #print new_args os.execv("/usr/bin/ffmpeg", new_args)
