Use mmpeg to encode AUDIO+IMAGE into a VIDEO for YouTube
12 June 2014, by pabloszI need to generate a video containing a single image throughout the duration of the audio comming from an audio file. This video should be compatible with the parameters supported by YouTube.
I’m using ffmpeg.
I was trying various configurations explained right here and in other forums but not all have worked well.
I’m currently using these settings:
ffmpeg -i a.mp3 -loop 1 -i a.jpg -vcodec libx264 -preset slow -crf 20 -threads 0 -acodec copy -shortest a.mkv
Where a.mp3 containing audio, a.jpg contains the image and a.mkv is the name of the resulting video.
Using these parameters a.mkv works well on YouTube and can be played with Media Player Classic; but KMPlayer only recognizes the audio, showing a blank image as background.
My questions are two:
1 - There is something wrong that causes KMPlayer to fail?
2 - Is there any configuration that can deliver the video faster, of course losing some compression?Muchas gracias!

FFmpeg live stream to Youtube with Raspberry Pi & USB Camera — What command to use for better quality?
4 August 2023, by qwet142I am currently streaming to Youtube live with the following command:


ffmpeg -re -f s16le -i /dev/zero -f v4l2 -thread_queue_size 512 -codec:v mjpeg -s 1920x1080 -i /dev/video0 -c:v libx264 -preset ultrafast -acodec aac -b:v 3500k -g 30 -f flv rtmp://a.rtmp.youtube.com/live2/key


The frame rate is great, and the speed is 1x. However, the quality is very poor, improved only slightly after increasing the bitrate to 3000k. Changing the resolution doesn't help, and using veryfast makes things worse. How can I fix the quality?


Note: there is no audio and this is a USB camera.

Convert youtube video files with ffmpeg to a format that can be playable on ios devices
26 December 2018, by AminI’ve created a
telegram robot
that downloads YouTube files and sends them to the user. Since most of our users useios
devices, Our first priority isios
.
Videos files play onWindows
andAndroid
but not broadcast onios
.
I convert format with ffmpeg after download from youtube:ffmpeg -i input.mp4 -strict -2 -vcodec mpeg4 output.mp4
But in addition to prolonging the processing time, the file size increases and eventually the file will not run again in
ios
.
