avformat/movenc : write the mdcv atom by default
28 mars 2020, par Michael Bradshawavformat/movenc : write the mdcv atom by default
The mdcv atom isn't in ISO/IEC 14496-12:2015 but it is expected to be
added soon. See :
http://ffmpeg.org/pipermail/ffmpeg-devel/2020-April/259529.htmlThe mdcv atom is already parsed in FFmpeg in mov.c.

React Electron ffmpeg-extract-frames build error
28 mars 2020, par taylorallen0913I am using the npm module ffmpeg-extract-frames for splitting video frames. It works completely fine when I am testing the module in a vanilla node environment. However, when I import the module in my Electron React desktop app component, it gives me a error when building.
This is how I am importing it :
const extractFrames = require("ffmpeg-extract-frames");This is the error I am getting when building in my React Electron component :

FFMPEG Merge Multiple Videos : No Audio Source for one of them
28 mars 2020, par Coach RoebuckI’ve written a node.js script to merge multiple video files into a single file. I’ve encountered a scenario in which no audio is provided for one of the input video files.
I first executed ffprobe so that I can access what I’ll refer to as the "video file spec". In this scenario, I created a basic module to help me better understand my problem :
Evaluation from all processes: [
{
fileName: 'input-0.mp4',
isVideoAvailable: true,
isAudioAvailable: false,
width: 1920,
height: 1080,
sampleRateAspectRatio: '1/1',
audioVolume: 1,
duration: '13.140000'
},
{
fileName: 'input-1.mp4',
isVideoAvailable: true,
isAudioAvailable: true,
width: 1920,
height: 1080,
sampleRateAspectRatio: '1/1',
audioVolume: 1,
duration: '17.160000'
},
{
fileName: 'input-2.mp4',
isVideoAvailable: true,
isAudioAvailable: true,
width: 1920,
height: 1080,
sampleRateAspectRatio: '1/1',
audioVolume: 1,
duration: '20.280000'
},
{
fileName: 'input-3.mp4',
isVideoAvailable: true,
isAudioAvailable: true,
width: 1920,
height: 1080,
sampleRateAspectRatio: '1/1',
audioVolume: 1,
duration: '19.020000'
},
{
fileName: 'input-4.mp4',
isVideoAvailable: true,
isAudioAvailable: true,
width: 1920,
height: 1080,
sampleRateAspectRatio: '1/1',
audioVolume: 1,
duration: '9.480000'
}
]This next block of code are the parameters that I’ve actually hard-coded in this case. The screen resolution and aspect ratio are manually set, as I discovered differing settings with each video I have been processing. These parameters allow FFMPEG to execute successfully under normal circumstances :
let ffmpegParameters = [
'-i',
'input-0.mp4',
'-i',
'input-1.mp4',
'-i',
'input-2.mp4',
'-i',
'input-3.mp4',
'-i',
'input-4.mp4',
'-f',
'lavfi',
'-t',
'0.1',
'-i',
'anullsrc',
'-filter_complex',
'[0:v]scale=1920:1080,setsar=1/1[v0];[0:a]volume=1.0[a0];[1:v]scale=1920:1080,setsar=1/1[v1];[1:a]volume=1.0[a1];[2:v]scale=1920:1080,setsar=1/1[v2];[2:a]volume=1.0[a2];[3:v]scale=1920:1080,setsar=1/1[v3];[3:a]volume=1.0[a3];[4:v]scale=1920:1080,setsar=1/1[v4];[4:a]volume=1.0[a4];[v0][a0][v1][a1][v2][a2][v3][a3][v4][a4]concat=n=5:v=1:a=1[v][a]',
'-map',
'[v]',
'-map',
'[a]',
'-c:v',
'libx264',
'-vsync',
'2',
'output.mp4'
]A comment from a different thread suggested to supply a dummy audio in cases such as mine. I’ve added that to no prevail :
'-f',
'lavfi',
'-t',
'0.1',
'-i',
'anullsrc',I do not know how to adjust the complex filter to account for my situation of the first video containing no audio. I’ve included the entire log below :
