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)------------------------------Print help / information / capabilities:-L :- show license-h :- topic show help-? :- topic show help-help :- topic show help-version :- show version-buildconf :- show build configuration-formats :- show available formats-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------------------------------Global options (affect whole program instead of just one file):
-loglevel :- loglevel set logging level-v loglevel :- set logging level-report :- generate a report-max_alloc bytes :- set maximum size of a single allocated block-y :- overwrite output files-n :- never overwrite output files-stats :- print progress report during encoding-max_error_rate :- ratio of errors (0.0: no errors, 1.0: 100% error maximum error rate
-bits_per_raw_sample :- number set the number of bits per raw sample-vol :- volume change audio volume (256=normal)Advanced global options:-cpuflags flags force specific cpu flags -hide_banner hide_banner do not show program banner -benchmark add timings for benchmarking -benchmark_all add timings for each task -progress url write program-readable progress information -stdin enable or disable interaction on standard input -timelimit limit set max runtime in seconds -dump dump each input packet -hex when dumping packets, also dump the payload -vsync video sync method -async audio sync method -adrift_threshold threshold audio drift threshold -copyts copy timestamps -copytb mode copy input stream time base when stream copying -dts_delta_threshold threshold timestamp discontinuity delta threshold -dts_error_threshold threshold timestamp error delta threshold -xerror error exit on error -filter_complex graph_description create a complex filtergraph -lavfi graph_description create a complex filtergraph -filter_complex_script filename read complex filtergraph description from a file -debug_ts print timestamp debugging info -intra deprecated use -g 1 -vdt n discard threshold -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 -dc precision intra_dc_precision -qphist show QP histogram -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
