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. In fact, as the owner of the fluent-ffmpeg repository said in one comment, there is no need to specify a real file name for the destination when using null format. libx264 libx264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (codec h264) If you don't want to save the ffmpeg process result to a file, one thing that comes to mind is to redirect the command output to /dev/null. D = Supports direct rendering method 1 V. You can also see the encoders and decoders for each codec. 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). 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 )ĭEV.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.
