Should a long Running video processing task to be done client side or server side
27 avril 2021, par Ritwiz SinhaI was creating an application in react for uploading video and using a REST API to send that to the server and store in S3. I also wanted the simple audio version of the video for some other tasks and I am confused as to what might be the better way :


- 

- Creating audio file on the fly when it is needed using node-ffmpeg package and not store it anywhere
- Start converting the video file to audio on the browser client only, and posting that to the server for storage along with the video.
- Just post the video to the server and use queue system for creating a new task for video conversion to audio and then save that to the S3 storage.
The second method seems to be saving some compute power on the server but it might be a problem if the video upload completes, audio conversion is still going on and the client disconnects.
Would appreciate some help, thanks.

Change bitrate of USB camera
12 décembre 2018, par Nick SawI use ELP USB camera with h264-codec output.
Ffmpeg-command to take the video stream :
ffmpeg -i /dev/video1 -c:v copy output.ts
As result I have a video with 4Mb bitrate - this value is too high for my task.
There is the same situation when I use GSTreamer :
gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-h264,width=1280,height=720,framerate=30/1 ! mpegtsmux ! filesink location=output.ts
I know that it’s possible to change the bitrate if we decode h264 the stream firstly and then encode it to h264 again. This operation requires too much CPU-power of my NanoPI device.
The main question is :
Is it possible to change a USB-camera’s bitrate without decoding ?Thanks in advance !

Android video encoding with fr and resolution manipulation
24 février 2017, par apSTRKI want to be able to take a video recorded with an Android device and encode it to a new Resolution and Frame Rate using my app. The purpose is to upload a much smaller version of the original video (in size), since this will be videos 30 min long or more.
So far, I’ve read of people saying FFmpeg is they way to go. However, the documentation seems to be lacking.
I have also considered using http opencv http://opencv.org/platforms/android.html
Considering I need to manipulate the video resolution and frame rate, which tool do you think can do such things better ? Are there any other technologies to consider ?
An important question is, since this will be long videos, is it reasonable to do the encoding in an android device (Consider power resources, time, etc.)
Thanks in advance !
