hw_base_encode : make recon_frames_ref optional
30 août 2024, par Lynnehw_base_encode : make recon_frames_ref optional
Vulkan supports some stupidly odd hardware, that unfortunately,
most modern GPUs happen to be.
The DPB images for encoders may be required to be preallocated
all at once, and rather than be individual frames, be layers of
a single frame.As the hw_base_encode code is written with the thought that either
the driver or the device itself supports sane image allocation,
Vulkan does not leave us with this option.So, in the case that the hardware does not support individual
frames to be used as DPBs, make the DBP frames context optional,
and let the subsystem manage this. -
Why is the audio recording on Chrome missing duration
16 août 2019, par Ivan SedelkinI’m sending some user created audio to a server which later passes it to googles speech to text api for transcription. Everything works perfectly on firefox but when I try it on Chrome it doesn’t work. I then installed FFmpeg to check if the metadata somehow changed for the file on chrome and noticed that the duration on the file is tagged "N/A". This does not happen on firefox.
This is the audio recorded from Chrome
Input #0, matroska,webm, from 'PATH_TO_FILE':
Metadata:
encoder : Chrome
Duration: N/A, start: 0.000000, bitrate: N/A
Stream #0:0(eng): Audio: opus, 48000 Hz, mono, fltp (default)This is the audio recorded from Firefox
Input #0, ogg, from 'PATH_TO_FILE':
Duration: 00:00:01.26, start: 0.000000, bitrate: 53 kb/s
Stream #0:0: Audio: opus, 48000 Hz, mono, fltp
Metadata:
ENCODER : Mozilla68.0The audio itself is recorded using the mediarecorder-api where the blob is later converted to base64-url and sent to my server.
This is the code that I use to record the audio :
navigator.mediaDevices
.getUserMedia(
// constraints - only audio needed for this app
{
audio: true
}
)
// Success callback
.then(function(stream) {
console.log(navigator.mediaDevices.getSupportedConstraints());
var mediaRecorder = new MediaRecorder(stream, { sampleRate: 44100 });
var chunks = [];
$(".rec-button")
.mousedown(function() {
console.log("rec start");
$(".rec-button i").addClass("recStart");
mediaRecorder.start();
console.log(mediaRecorder.state);
console.log("recorder started");
})
.mouseup(function() {
console.log("rec end");
$(".rec-button i").removeClass("recStart");
mediaRecorder.stop();
mediaRecorder.ondataavailable = function(e) {
chunks.push(e.data);
var blob = new Blob(chunks, { type: "audio/ogg; codecs=opus" });
var player = document.getElementById("player");
player.src = URL.createObjectURL(blob);
chunks = [];
var reader = new window.FileReader();
reader.readAsDataURL(blob);
reader.onloadend = function() {
var base64 = reader.result;
var audioArr = {
audio: base64
};
$.ajax({
url: "http://localhost:4242/api/1.0/post",
type: "POST",
contentType: "application/json",
dataType: "json",
data: JSON.stringify(audioArr),
success: function(response) {
console.log(response);
},
error: function(err) {
console.log(err);
}
});
};
console.log(mediaRecorder.state);
console.log("recorder stopped");
};
});
})
// Error callback
.catch(function(err) {
console.log("The following getUserMedia error occured: " + err);
});My goal is that the audio file recorded from chrome has a duration so that the google api can transcribe it. If you guys have any way of overcoming this problem I would be grateful

JW Player can't play mp4 video downloaded from youtube
20 janvier 2015, par kheyaI have doenloaded am mp4 video using IE Realplayer plugin from youtube.
https://www.youtube.com/watch?v=e3a80c5Ar3YI have a test site on my local machine where I have HTML5 JW Player.
I download the video and then play locally using realplay to see if it plays.
I notice that not all mp4 downloads from youtube plays in Realplayer.
The ones that play in Realplayer also play in JW Player on local website.
But the mp4 files that don’t play in Realplayer also don’t play in JW player.This is the error I get in the player :
the video playback was aborted due to a corruption problem or because the video used features your browser didnot support mylocalsite/xyz.mp4 undefinedI tested IE, FF, Chrome. It works nowhere.
Here is my jw player setup and html :
<video src="mylocalsite/test.mp4" type="video/mp4" poster="mylocalsite/test.jpg" width="640" height="360"></video>
player setup :
var modes = '';
var swfPath = '/content/jw/player.swf';
if (navigator.userAgent.toLowerCase().match(/(android)/) || navigator.userAgent.toLowerCase().match(/(chrom)/)) {
modes = [{ type: 'flash', src: swfPath }, { type: "html5"}];
} else {
modes = [{ type: 'html5' }, { type: 'flash', src: swfPath }, { type: "download"}];
}
jwplayer('container').setup({
