【carrierwave+ffmpeg】can't upload the video with sound
10 avril 2020, par ken akitaI want to make "Fake Instagram" Rails application.
then I made the uploader and I can upload the video(mp4), but no sound.
I can listen to the sound on my desktop but can't on my application, like this image, speakers not working.
enter image description here



Code is here. I guess something wrong with image_uploader.rb or show.html.erb.
Note that first I made the ImageUploader to upload image, then I want to add video posting system to upload video. Both uploading done, but video without sound.
Really thank you for your advise !



*image_uploader.rb
require 'streamio-ffmpeg'

class ImageUploader < CarrierWave::Uploader::Base
 include CarrierWave::MiniMagick
 process resize_to_fit: [230, 183]

 storage :file

 def store_dir
 "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
 end

 version :thumb do
 process resize_to_fit: [230, 183]
 end
 version :screenshot do
 process :screenshot
 def full_filename (for_file = model.logo.file)
 "screenshot.jpg"
 end
 end

 def screenshot
 tmpfile = File.join(File.dirname(current_path), "tmpfile")

 File.rename(current_path, tmpfile)

 movie = FFMPEG::Movie.new(tmpfile)
 movie.screenshot(current_path + ".jpg", {resolution: '230x183' }, preserve_aspect_ratio: :width)
 File.rename(current_path + ".jpg", current_path)

 File.delete(tmpfile)
 end

GStreamer : How to set "stream-number" pad property of mpegtsmux element ? [closed]
8 novembre 2024, par TishSergAccroding to
gst-inspect-1.0 mpegtsmux, mpegtsmux's sink pads have writablestream-numberproperty :

...
Pad Templates:
 SINK template: 'sink_%d'
 Availability: On request
 Capabilities:
 ...
 Type: GstBaseTsMuxPad
 Pad Properties:
 ...

 stream-number : stream number
 flags: readable, writable
 Integer. Range: 0 - 31 Default: 0


But when I try to set it, GStreamer says there's no such property. The following listing shows I can run multi-stream pipeline without setting that property, but when I add that property it doesn't work.

I even updated GStreamer, but still no luck. I tried that because I found news saying there were updates regarding that property :


397 ### MPEG-TS improvements
 398 
 399 - mpegtsdemux gained support for
 400 - segment seeking for seamless non-flushing looping, and
 401 - synchronous KLV
 402 - mpegtsmux now
 403 - allows attaching PCR to non-PES streams
 404 - allows setting of the PES stream number for AAC audio and AVC video streams via a new “stream-number” property on the
 405 muxer sink pads. Currently, the PES stream number is hard-coded to zero for these stream types.


The syntax seems correct (pad_name::pad_prop_name on the element). I ran out of ideas about what I'm doing wrong with that property.


Broader context :


I want to set that property because I want an exact sequence of streams I mixing.


When I feed
mpegtsmuxwith two video streams and one audio stream (from capture devices) without specifying the stream numbers I get them muxed in a random sequence (checking it usingffprobe). Sometimes they are in the desired sequence, but sometimes they aren't. The worst case is when the audio stream is the first stream in the file, so video players get mad when trying to play such.tsfile. I have to remux such files using-mapkey offfmpeg. If I could set exact stream indices inmpegtsmux(not to be confused with stream PID) I could avoid analyzing actual stream layout and remuxing.

Example of the real layout of the streams (
ffprobeoutput) :

Input #0, mpegts, from '████████████████████████████████████████':
 Duration: 00:20:09.64, start: 3870.816656, bitrate: 6390 kb/s
 Program 1
 Stream #0:2[0x41]: Video: h264 (Baseline) (HDMV / 0x564D4448), yuvj420p(pc, bt709, progressive), 1920x1080, 30 fps, 30 tbr, 90k tbn
 Stream #0:1[0x4b]: Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, mono, fltp, 130 kb/s
 Program 2
 Stream #0:0[0x42]: Video: h264 (High) (HDMV / 0x564D4448), yuv420p(progressive), 720x576, 25 fps, 25 tbr, 90k tbn


You can see 3 streams :


- 

- FullHD video with PID 0x41 (defined by me as
mpegtsmux0.sink_65) has index 2 while I want it to be 0 - PAL video with PID 0x42 (defined by me as
mpegtsmux0.sink_66) has index 0 while I want it to be 1 - Audio with PID 0x4b (defined by me as
mpegtsmux0.sink_75) has index 1 while I want it to be 2
