This will return all options and parameters when encoding with this encode method. To view more details on an encoder ffmpeg -h encoder=libx264 Libx264 encoder only supports video (V) also provided is the codec. D = Supports direct rendering method 1 V. Frame-type options: g Keyframe interval, also known as GOP length.FFmpeg developer superdump has implemented x264 presets to FFmpeg. ![]() Additionally the x264opts and x264-params private options allows one to pass a list of keyvalue tuples as accepted by the libx264 x264paramparse function. You can also see the encoders and decoders for each codec. This guide maps most of libx264's options to FFmpeg's options along with detailed descriptions by x264 developer DarkShikari. Many libx264 encoder options are mapped to FFmpeg global codec options, while unique encoder options are provided through private options. Looking at two popular codecs returned, h264 has DEV.LS whilst h265 has DEV.L meaning h265 is missing Lossless compression ability (In this version). 2 Answers Sorted by: 3 Is there not any error message when you configure ffmpeg Or you can command ffmpeg, and show the configuration like configuration: -enable-shared -enable-libx264 -enable-libx265 -enable-gpl -enable-nonfree Maybe you can try install x264 from source. hevc H.265 / HEVC (High Efficiency Video Coding) (decoders: hevc hevc_qsv hevc_cuvid ) (encoders: libx265 nvenc_hevc hevc_amf hevc_nvenc hevc_qsv ) S = Lossless compression DEV.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders: h264 h264_qsv h264_cuvid ) (encoders: libx264 libx264rgb h264_amf h264_nvenc h264_qsv nvenc nvenc_h264 )ÄEV.L. To list all codecs in FFmpeg simply do ffmpeg -codecs ![]() Think putting many frames and audio together and playing them back or when you skip ahead providing the right data. A codec is the logic to encoding or decoding a media stream, there are many different types with popular ones being H.264, HEVC ( H.265) and MPEG-4.Ĭodecs are different to containers like MP4, MKV and MOV because a codec manages the bitrate, resolution and frames whilst the container organizes and returns the data as sequence.
