Hyper fast Audio and Video encoder usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}... Getting help: -h -- print basic options -h long -- print more options -h full -- print all options (including all format and codec specific options, very long) -h type=name -- print all options for the named decoder/encoder/demuxer/muxer/filter See man ffmpeg for detailed description of the options. Print help / information / capabilities: -L show license -h topic show help -? topic show help -help topic show help --help topic show help -version show version -buildconf show build configuration -formats show available formats -devices show available devices -codecs show available codecs -decoders show available decoders -encoders show available encoders -bsfs show available bit stream filters -protocols show available protocols -filters show available filters -pix_fmts show available pixel formats -layouts show standard channel layouts -sample_fmts show available audio sample formats -colors show available color names -sources device list sources of the input device -sinks device list sinks of the output device -hwaccels show available HW acceleration methods Global

info -intra deprecated use -g 1 -sameq Removed -same_quant Removed -deinterlace this option is deprecated, use the yadif filter instead -psnr calculate PSNR of compressed frames -vstats dump video coding statistics to file -vstats_file file dump video coding statistics to file -qphist show QP histogram -hwaccel_lax_profile_check attempt to decode anyway if HW accelerated decoder's supported profiles do not exactly match the stream -vc channel deprecated, use -channel -tvstd standard deprecated, use -standard -isync this option is deprecated and does nothing -override_ffserver override the options from ffserver -sdp_file file specify a file in which to print sdp information Per-file main options: -f fmt force format -c codec codec name -codec codec codec name -pre preset preset name
