You can try to following below command. $ ffmpeg -f image2 -i image%d.jpg imagestovideo.mpg Convert mp4 to webm i flag signifies input (the video file) and map 0:a picks up the available audio streams -codec flag copies the picked up audio stream (without re-encoding. $ ffmpeg -i video.flv image%d.jpg Convert Images into a Video ffmpeg -i sourcevideo.mp4 -i sourceaudio.wav -acodec copy -vcodec copy. Ls * | perl -ne 'print "file $_"' | ffmpeg -f concat -i -c copy merged.mp4 Split a Video into Images To replace audio in a video without having to re-encode the video you can use a. You can get the list of supported formats with:Ĭonvert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:įfmpeg -i input.wav -ac 1 -ab 64000 -ar 22050 output.mp3Ĭonvert any MP3 file to WAV 16khz mono 16bit:įfmpeg -i 111.mp3 -acodec pcm_s16le -ac 1 -ar 16000 out.wavĬonvert any MP3 file to WAV 20khz mono 16bit for ADDAC WAV Player:įfmpeg -i 111.mp3 -acodec pcm_s16le -ac 1 -ar 22050 out.wavįor i in *.mp3 do ffmpeg -i "$i" -acodec pcm_s16le -ac 1 -ar 22050 "$.mp3" done Merge Multiple Videosįile names in folder, if they contain spaces, must be properly escaped Another way we can impact quality is to adjust the frame rate of the video using the -r option: ffmpeg-i input.webm -c:a copy -c:v vp9 -r 30 output. Minimal example: transcode from MP3 to WMA: This will copy the audio (-c:a copy) from input.webm and convert the video to a VP9 codec (-c:v vp9) with a bit rate of 1M/s (-b:v), all bundled up in a Matroska container (output.mkv). The last param is the name of the output. The third option i.e -ab 192000 tells ffmpeg that we want the output to be encoded at 192Kbps and -vn tells ffmpeg that we dont want video. The second option -f mp3 tells ffmpeg that the ouput is in mp3 format.
