Above error is the warning or the grey frames?. a) If ffplay can play it well/correctly ffmpeg can transcode it without major issues. b) If it's the grey frames, don't know how to fix it, sorry. Some blindshoots with vlc: c1) In vlc, go to ctrl+P 'preferences', select 'all settings' (bottom left), 'input/codecs', 'video codecs', 'ffmpeg', 'error resilience' set it to 4 c2) In vlc, go to ctrl+P 'preferences', select 'all settings', 'input/codecs', 'video codecs', 'ffmpeg', 'workaround bugs', try with values 2, 16 and 18 Also, with ctrl+M and setting to 1 or 2 the verbosity level you can see what vlc is doing and why.
