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 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 -ignore_unknown Ignore unknown stream types -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 -copy_unknown Copy unknown stream types -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 -frame_drop_threshold frame drop threshold -async audio sync method -adrift_threshold threshold audio drift threshold -copyts copy timestamps -start_at_zero shift input timestamps to start at 0 when using copyts -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 -abort_on flags abort on the specified condition flags -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 -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 -map_metadata outfile[,metadata]:infile[,metadata] set metadata information of outfile from infile -t duration record or transcode "duration" seconds of audio/video -to time_stop record or transcode stop time -fs limit_size set the limit file size in bytes -ss time_off set the start time offset -sseof time_off set the start time offset relative to EOF -seek_timestamp enable/disable seeking by timestamp with -ss -timestamp time set the recording timestamp ('now' to set the current time) -metadata string=string add metadata -program title=string:st=number... add program with specified streams -target type specify target file type ("vcd", "svcd", "dvd", "dv" or "dv50" with optional prefixes "pal-", "ntsc-" or "film-") -apad audio pad -frames number set the number of frames to output -filter filter_graph set stream filtergraph -filter_script filename read stream filtergraph description from a file -reinit_filter reinit filtergraph on input parameter changes -discard discard -disposition disposition Advanced per-file options: -map [-]input_file_id[:stream_specifier][,sync_file_id[:stream_s set input stream mapping -map_channel file.stream.channel[:syncfile.syncstream] map an audio channel from one stream to another -map_chapters input_file_index set chapters mapping -accurate_seek enable/disable accurate seeking with -ss -itsoffset time_off set the input ts offset -itsscale scale set the input ts scale -dframes number set the number of data frames to output -re read input at native frame rate -shortest finish encoding within shortest input -copyinkf copy initial non-keyframes -copypriorss copy or discard frames before start time -tag fourcc/tag force codec tag/fourcc -q q use fixed quality scale (VBR) -qscale q use fixed quality scale (VBR) -profile profile set profile -attach filename add an attachment to the output file -dump_attachment filename extract an attachment into a file -stream_loop loop count set number of times input stream shall be looped -thread_queue_size set the maximum number of queued packets from the demuxer -autorotate automatically insert correct rotate filters -muxdelay seconds set the maximum demux-decode delay -muxpreload seconds set the initial demux-decode delay -bsf bitstream_filters A comma-separated list of bitstream filters -fpre filename set options from indicated preset file -max_muxing_queue_size packets maximum number of packets that can be buffered while waiting for all streams to initialize -dcodec codec force data codec ('copy' to copy stream) Video options: -vframes number set the number of video frames to output -r rate set frame rate (Hz value, fraction or abbreviation) -s size set frame size (WxH or abbreviation) -aspect aspect set aspect ratio (4:3, 16:9 or 1.3333, 1.7777)
