Convert png images to HEVC with alpha video via ffmpeg [closed]
6 mai 2024, par foxhableI am trying to create a video from a sequence of png images in the HEVC with alpha codec via ffmpeg.


After the command


ffmpeg -i a%d.png -r 30 -c:v hevc_videotoolbox -allow_sw 1 -alpha_quality 1 -vtag hvc1 ffmpeg-hevc.mov



I get a video with a transparent background that opens in QuickTime, but not Safari.


Info about this video via ffprobe :


ffprobe .\ffmpeg-hevc.mov
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '.\ffmpeg-hevc.mov':

I compared this to a video that has a transparent background and works in Safari and QuickTime


ffprobe movie-hevc.mov

The only thing I noticed is the encoder. In the working version this is HEVC but in my Lavc61.5.103 hevc_videotoolbox.


The question is, is it possible to create a video with a native HEVC codec via ffmpeg ?

Building my JAVA parameter array for FFMPEG
29 janvier 2016, par user3541092FFmpeg Version : N-63893-gc69defd Copyright (c) 2000-2014 the FFmpeg developers
built on Jul 16 2014 05:38:01 with gcc 4.6 (Debian 4.6.3-1)Machine : Amazon Linux t2.micro (free tier)
Sample File : sample_iTunes.mov
Sample File URL : https://support.apple.com/en-us/HT201549I’m trying to replicate the following FFmpeg command, using a string array and then pass this array into the Runtime.getRuntime().exec().
ffmpeg -i file:/var/local/ffmpegtest/media_input/sample_iTunes.mov -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand="mp42" -b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler="Stereo" /var/local/ffmpegtest/media_output/sample_iTunes.mp4 -y
NOTE : This works when I pass the full command, as a single string into Runtime.getRuntime().exec().
String _cmd = "ffmpeg -i %s -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand=\"mp42\" "
+ "-b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler=\"Stereo\" %s -y";
String _ffmpegCommand = String.format(_cmd, _inputFile, _outPutFile);
p = Runtime.getRuntime().exec(_ffmpegCommand);
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}I started out with just a basic parameter list. As I add add each additional parameter, I re-build the JAR file and upload it to my EC2 instance to test for any errors.
The following string array works :
try
{
String[] _params = {"ffmpeg",
"-i",
String.format("%s", _inputFile),
"-pix_fmt",
"yuv420p",
"-c:v",
"libx264",
String.format("%s", _outPutFile),
"-y"};
p = Runtime.getRuntime().exec(_params);
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}
}
catch (Exception e) {
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}
}However, when I continue to build the array with additional parameters, I begin to experience problems (lets add -vtag mp42) :
try
{
String[] _params = {"ffmpeg",
"-i",
String.format("%s", _inputFile),
"-pix_fmt",
"yuv420p",
"-c:v",
"libx264",
"-vtag", // <---- New
"mp42", // <--- New
String.format("%s", _outPutFile),
"-y"};
p = Runtime.getRuntime().exec(_params);
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}
}
catch (Exception e) {
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}
