RecordRTC only recording stop after 1min
2 novembre 2015, par Mick JackI am using RecordRTC to record a webcam stream and using ffmpeg to convert the output into .mp4 recording of 1min video is fine and the browser merge both the audio and video into a single .mp4 however recording that is longer than 1min will encounter this error.
My Sample Code
function setupNewBroadcastButtonClickHandler() {
document.getElementById('broadcast-name').disabled = true;
document.getElementById('setup-new-broadcast').disabled = true;
//document.getElementById('save-video').disabled = true;
captureUserMedia(function() {
var shared = 'video';
broadcastUI.createRoom({
roomName: (document.getElementById('broadcast-name') || {}).value || 'Anonymous',
isAudio: shared === 'audio'
});
});
hideUnnecessaryStuff();
}
var audioRecorder, videoRecorder, videoURL, connectionStream;

//document.getElementById('start-recording').disabled = false;
document.getElementById('stop-recording').disabled = false;
//document.getElementById('save-video').disabled = false;
//document.getElementById('start-recording').onclick = function() {
this.disabled = true;
audioRecorder = RecordRTC(stream, {
recorderType: StereoAudioRecorder,
bufferSize: 16384, // mandatory: if 720p output is forced. otherwise: optional
width: 1280, // optional---- to get 720p output
height: 720
});
videoRecorder = RecordRTC(stream, {
type: 'video',
frameInterval: 90
});
videoRecorder.initRecorder(function() {
audioRecorder.initRecorder(function() {
audioRecorder.startRecording();
videoRecorder.startRecording();
});
});
//};
document.getElementById('stop-recording').onclick = function() {
this.disabled = true;

classes.jar not getting generated in .aar file
20 septembre 2016, par vasanthI am using Android Studio AI-141.216xxx.
I generated a .aar file from FFMPEG module/library from this project :
https://github.com/WritingMinds/ffmpeg-android-javaI then tried to import a .aar locally into a module in some other application.
imports were failing.
But, when I checked in the ’generated’ folder,
I see that classes.jar is empty.Would you know why this is happening ? Any pointer is highly appreciated.
Thanks in advance. -
Trimming of videos using FFMPEG [on hold]
14 décembre 2015, par Praveen RawatI have downloaded video trimming code from github from this https://github.com/uday-rayala/video-trimmer
It’s working perfectly for the first time, but when I try to run it for the second time the code crashes without any exception then again when I try to run it for the 3rd time after the crash it works ! Does any one have any idea for this kind of behaviour ?
I am also developing an application which has one module of trimming videos. I would really appreciate it, if any one could help me .this question asked , but cant understand what i have to done . Please sort out this.
