FFMpeg Combine wav and avi to mp4
15 avril 2016, par krisphI am trying to combine a wav file and a avi in to a single mp4.
I can do this with the following via php :
$command = 'start /B convertvid\bin\ffmpeg -nostdin -i Temp\\temp.avi -i Temp\\temp.wav -y -filter:v scale=1920:-1 -c:v libx264 -preset ultrafast -movflags faststart -crf 31 -c:a libvo_aacenc -b:a 64k Temp\\output.mp4';However it takes an age to complete and i need to speed it up, i was just wondering is there anything that could be done to optimize the commands to make it faster ?
I have tried the command using just the command line and it still takes ages...
C:\inetpub\wwwroot\Update\>convertvid\bin\ffmpeg -i Temp\temp.
avi -i Temp\temp.wav -y -c:v libx264 -preset ultrafast -movflags faststart -crf
31 -c:a libvo_aacenc -b:a 64k Temp\testhis.mp4

Converting RGB to YUV, + ffmpeg
10 juillet 2012, par TheSHEEEPI am trying the following to record a live video from my Flash/AIR application :
- I take a "screenshot" (BitmapData from stage) each frame.
-
I convert each pixel to yuv format like this (V2) :
var file :File = new File(_appUrl + "/creation/output.raw");
var fs :FileStream = new FileStream();
fs.open(file, FileMode.WRITE);
var finalY :ByteArray = new ByteArray();
var finalU :ByteArray = new ByteArray();
var finalV :ByteArray = new ByteArray();
var rect :Rectangle = new Rectangle(0, 0, 600, 700);
var pixels :ByteArray;
var pixel :uint;
var r :uint;
var g :uint;
var b :uint;
_screenBuffer = _screenBuffer.reverse();
while (_screenBuffer.length > 0)
{
pixels = BitmapData(_screenBuffer.pop()).getPixels(rect);
pixels.position = 0;
// Convert and save each pixel
for (var x:int = 0; x < 600; x++)
{
for (var y:int = 0; y < 700; y++)
{
// Convert to yuv
pixel = pixels.readUnsignedInt();
r = pixel >> 16 & 0xff;
g = pixel >> 8 & 0xff;
b = pixel & 0xff;
// Y' is written for each pixel
finalY.writeByte(0.257 * r + 0.504 * g + 0.098 * b + 128);
// U and V are written once per 2x2 pixel block
if (x % 2 == 0 && y % 2 == 0)
{
finalU.writeByte(-0.148 * r - 0.291 * g + 0.439 * b + 128);
finalV.writeByte(0.439 * r - 0.368 * g - 0.071 * b + 128);
}
}
}
}
// Write the converted bytes to the file
finalY.position = 0;
finalU.position = 0;
finalV.position = 0;
fs.writeBytes(finalY, 0, finalY.length);
fs.writeBytes(finalU, 0, finalU.length);
fs.writeBytes(finalV, 0, finalV.length);
fs.close(); -
I use the following line of ffmpeg to convert the raw file to a video :
ffmpeg -r 30 -pix_fmt yuv420p -s 600x700 -vcodec rawvideo -f rawvideo -i output.raw -y test.mp4
A video is created, but it is simply a mess, barely resembling what was recorded. I know that the capturing process works, as I have tried the same BitmapData "screenshots" with the SimpleFlvWriter.
So, either something is wrong with my conversion or with the ffmpeg line, but I have no idea.
This is what ffmpeg outputs when creating the video, maybe it can help someone :

Here is a zip that contains one of the frames and the video output. What should be visible is a green smiling pear, without any artifacts. Remember the size is 600x700 and the format yuv420. Best to view such raw image files with irfanview, IMO. Don't mind the noise, its from pushing against my microphone ;)

Encode videos to send with WhatsApp
28 avril 2017, par piegamesI have a series of PNG images of a video I rendered and now I want so send it via WhatsApp. I used to encode my videos with the command from this answer, but apparently the videos can only be played from WhatsApp web ; on the phone I still get an error message. How do I convert them so that they can also be played on phone ?
