#Ffmpeg concat vorbis encoder error fullcmp : Full pel motion estimation compare function. bufsize : Set rate control buffer size ( in bits ). b_strategy : Strategy to choose between I/P/B-frames ( 0 = off / 1 = on ). bf : Set number of B-frames ( supported for MPEG-1, MPEG-2 and MPEG-4 ). b : Set video bitrate in bit/s ( default = 200k ). async 1 is a special case where only the start of the audio stream is corrected without any later correction. The parameter is the maximum samples per second by which the audio is changed. Audio will be stretched or squeezed to match the timestamps. ar : Set audio sampling frequency in Hz ( default = 44100 Hz ). Pcm_s16le : Uncompressed 16-bit PCM Audio ab : Set audio bitrate in bit/s ( default = 64k ). Each occurrence is then applied to the next input or output file. Therefore, order is important and you can have the same option on the command line multiple times. Note : As a general rule, options are applied to the next specified file. #Ffmpeg concat vorbis encoder error pro$ ffmpeg -i normal_export.mkv -i normal_export_Audio_1.mkv -map 0:0 -map 1:1 -c:v copy -c:a copy normal_export_final.O D10 into QuickTime ( for Final Cut Pro import )įfmpeg ].
