How to do multiple input with streamio-ffmpeg ?
12 août 2020, par YozuuI would like to recreate this ffmpeg line (which works well) in my rails app :


ffmpeg -i 1.mp4 -i 2.mp4 -filter_complex '[0] [1] afir=dry=10:wet=10' output.wav



So here is my config :


module EncodingConstants
 PROCESSED_DEFAULTS = {
 resolution: '500x400',
 video_codec: 'libx264',
 constant_rate_factor: '30',
 frame_rate: '25',
 audio_codec: 'aac',
 audio_bitrate: '128k',
 audio_sample_rate: '48000',
 progress: :processing_progress
 }.freeze

 AUDIO_EFFECTS = {
 multi_effect: %w[-i /home/yozuu/2.mp4 -filter_complex [0] [1] afir=dry=10:wet=10]
 }.freeze



So Sidekiq send this back to me :

.....

Unknown decoder 'libx264'

Errors: no output file created. 




I don't understand why because for me the command line ffmpeg seems correct.
Anyone have a idea ?
Thank you.

FFmpeg weird codec id for wav_pcm
1er février 2021, par phongelegobSo, I want to convert a lot of 32 bit .wav files into 24 bit .wav ones because i want to import them into Omnisphere, a virtual synth. I tried to convert them all with FFmpeg but Omnisphere doesn't support them. I then tested some things and Omnisphere seems to support the audio exported from Edison, which is FL Studio audio editing and recording tool. As I don't want to export them all individually, i wanted to know if there's any way to fix this in FFmpeg or in another audio converter. Here are the test files and what they output in MediaInfo : https://www.mediafire.com/file/l6lojwswsaq9fly/audiotest+wav.zip/file

Convert set of PNGs into rawvideo .raw FFMPEG
13 août 2020, par WireRecently, I have been trying to modify the boot animation of a little robot. It is a .raw file and it contains every RGB565 frame one after the other. I have been able to get all of the frames using


ffmpeg -f rawvideo -pixel_format rgb565 -video_size 184x96 -framerate 10 -i "boot_anim.raw" -r 1/1 boot_anim%02d.png


But if I try to repack it with


ffmpeg -i boot_anim%02d.png -f rawvideo -pix_fmt rgb565 -framerate 10 -video_size 184x96 -r 1/1 "boot_anim.raw"


it only puts in the first two frames and nothing else. I have also tried libx264 and putting in vcodecs manually. Same result. I'm new to ffmpeg and Linux overall.


Here is the full output :
