![]() output like in your example (although your command line ffmpeg wasn't doing that). If you want multiple outputs, you can add more. You can add multiple input or output options in one line using an array of options, the fluent ffmpeg github will also point you to some javascript code that works as shortcuts for some of these commands, although I still find it easier to use command line syntax. outputOptions()īasically, anything before -i is considered an input option, and anything between the input and output file is considered an output option. ![]() To estimate percentage, fluent-ffmpeg has to guess what the total output duration will be, and uses the first input added to the command to do so. Any result greater than 35dB would be acceptable for most streaming use cases. ![]() Adds the psnr flag so that we can get the transcode's peak signal-to-noise ratio. / encoding is complete, so callback or move on at this point Note that percent can be (very) inaccurate, as the only progress information fluent-ffmpeg gets from ffmpeg is the total number of frames written (and the corresponding duration). Using fluent-ffmpeg to quickly create an MP4->WebM transcode with VP8 video. / do stuff with progress data if you want Try this: var ffmpeg = require('fluent-ffmpeg') ![]() Output both per-frame SSIM data during encoding and average SSIM at the end of encoding to stdout. The -r command sets the output frame rate (1) and image2 is an image file muxer that is used to write video frames to image files.FFmpeg for Android, iOS and tvOS. ffmpeg -i foo.mov -c:v libxvid -pass 1 -an -f rawvideo -y /dev/null. You redirect the output to a file: ffprobe -showframes -of compactp0 -f lavfi 'movietest.mp4,selectgt(scene,0.3)' > output.txt 2>&1 If you want separate files for stdout and stderr you can do.You've probably figured this out by now, but I'll answer anyway. ffmpeg is a very fast video and audio converter that can also grab from a live audio/video source. ![]()
