Android yuv_420_888 mp4 1080p output is graysale on some devices like S21 and green bars on S22

I am trying to make an mp4 video recoding, its not working on all android devices and I am getting grayscale recordings on S21 Android OS 12, S22 Green bars
Not sure where I went wrong, Following is all the possible code that could impact
What I am expecting is that it should work on all devices producing colored 1080p mp4 video and no green bars

Unable to upload a file through multipart form data from java as well as postman

I have been trying to upload a file from java as well as postman. But I am unable to upload. The server is giving back the response as 200 Ok. But, the file is not being uploaded.
API Details:
I have an API for uploading file as "FileExplorerController". This API has a method "upload()" to upload the files. Url to access this method is"/fileupload". The API is working fine if I upload a file through HTML UI.
But I am trying to upload using Java. I have tried using Postman as well.
I have passed the multipart form data in several ways. But unable to resolve the issue. The code is as follows.

Request body empty (?) after migrating to Endpoints Framework 2.0

I have a Java Google Endpoint as follows
#ApiMethod(
name="createShiftlist",
path="jeugdhuis/{websafeJeugdhuisKey}/shiftlists",
httpMethod="POST",
authenticators={FirebaseAuthenticator.class}
)
public void createShiftlist(User user, #Named("websafeJeugdhuisKey") String websafeJeugdhuisKey, ShiftlistForm shiftlistForm)
throws UnauthorizedException {
if (shiftlistForm.getStart() == null)
throw new IllegalArgumentException(shiftlistForm.getStart() + " " + shiftlistForm.getPartyName() + " " + shiftlistForm.getEnd());
if (user == null)
throw new UnauthorizedException("User is not logged in!");
if (!JukteUserAPI.isJeugdhuisAdmin(user, websafeJeugdhuisKey))
throw new UnauthorizedException("Logged in user is not an admin of the given Jeugdhuis.");
OfyService.ofy().save().entities(new Shiftlist[] {
new Shiftlist(
OfyService.factory().allocateId(Key.create(websafeJeugdhuisKey), Shiftlist.class).getId(),
websafeJeugdhuisKey, shiftlistForm.getPartyName(), shiftlistForm.getStart(), shiftlistForm.getEnd())
});
}
I use the following .js to call it.
var jukteapi = jukteapi || {};
var jukteKey = 'myKey';
function XHRBuilder(appId, apiName, version) {
this.root = "https://" + appId + ".appspot.com/_ah/api/" + apiName + "/" + version + "/";
this.params;
this.method;
this.endpoint;
this.authorizationToken;
this.onsucces;
this.get = function() {
this.method = 'GET';
return this;
};
this.post = function() {
this.method = 'POST';
return this;
};
this.delete = function() {
this.method = 'DELETE';
return this;
};
this.put = function() {
this.method = 'PUT';
return this;
}
this.path = function(endpointPath) {
this.endpoint = endpointPath;
return this;
};
this.authorizationToken = function(token) {
this.authorizationToken = token;
return this;
};
this.onsucces = function(func) {
this.onsucces = func;
return this;
};
this.addParam = function(paramName, paramValue) {
if (this.params === undefined)
this.params = new FormData();
this.params.append(paramName, paramValue);
return this;
};
this.send = function() {
var xhr = new XMLHttpRequest();
xhr.open(this.method, this.root + this.endpoint);
var self = this.onsucces;
xhr.onreadystatechange = function() {
if (xhr.readyState == 4 && xhr.status == 200)
self(JSON.parse(xhr.responseText));
else if (xhr.readyState == 4 && xhr.status == 204)
self();
else if (xhr.readyState == 4 && xhr.status == 400)
alert(JSON.parse(xhr.responseText).error.message);
};
xhr.setRequestHeader('Authorization', 'Bearer ' + this.authorizationToken);
if (typeof this.params !== "undefined")
for (var pair of this.params.entries()) {
console.log(pair[0]+ ', ' + pair[1]);
}
xhr.send(this.params);
};
}
jukteapi.http = function() {
return new XHRBuilder('jhjukte','jukte','v1')
}
jukteapi.createShiftlist = function(onsucces, name, start, end) {
firebase.auth().currentUser.getIdToken().then(function(idToken) {
jukteapi.http().post()
.path('jeugdhuis/' + jukteKey + '/shiftlists')
.authorizationToken(idToken)
.addParam('partyName', name)
.addParam('start', start + ':00')
.addParam('end', end + ':00')
.onsucces(onsucces)
.send();
});
}
This is the ShiftlistForm class.
package jukte.form;
import java.util.Date;
public class ShiftlistForm {
private String partyName;
private Date start;
private Date end;
#SuppressWarnings("unused")
private ShiftlistForm() {}
public ShiftlistForm(String partyName, Date start, Date end){
this.partyName = partyName;
this.start = start;
this.end = end;
}
public String getPartyName() {
return partyName;
}
public Date getStart() {
return start;
}
public Date getEnd() {
return end;
}
public void setPartyName(String partyName) {
this.partyName = partyName;
}
public void setStart(Date start) {
this.start = start;
}
public void setEnd(Date end) {
this.end = end;
}
}
The endpoint is called, but the variables in ShiftlistForm (start, end, partyName) are null. It worked perfectly before I migrated to 2.0 from 1.0. What is going on?

I believe you may want to try setting your Content-Type header to application/json.

Primefaces wizard. How to return js function tab for onnext

I use Primefaces 3.5. And try to call js function in onnext handler of <p:wizard/>.
I want that onnext return on tab on specific tab after validation result ob current tab. My validation function
function validateManageOtherTournaments(wizard, validationTab, lang) {
var currentTabId = validationTab;
if (currentTabId != 'competitionId') {
return wizard.next();
}
var seasonVal = document.getElementById('manageTournament:name_season_input').value;
var dateFromVal = document.getElementById('manageTournament:dateFrom_input').value;
var dateToVal = document.getElementById('manageTournament:dateTo_input').value;
/*var compNameVal = document.getElementById('manageTournament:title_input').value;*/
var isValidName = validateFieldsInOtherTournament('manageTournament', ['title'], lang);
if (isValidName) {
if (validRuContentT) {
var filledBothDate = (dateFromVal != "" && dateToVal != "");
var isEmptySeason = ("" != String(seasonVal));
if ( filledBothDate || isEmptySeason) {
return wizard.next();
}
}
}
return "competitionId"; // currentTab
}
I use code js wizard. But it still doesn't work.(
//UPDATED
I try to do something like this
function validateManageOtherTournaments(wizard, validationTab, lang) {
/*var wizardElement = document.getElementById('wiz');*/
var currentTabId = validationTab;
if (currentTabId != 'competitionId') {
var currentStepIndex = wizard.getStepIndex(wizard.getState().currentStep),
stepIndexToGo = currentStepIndex + 1;
var stepIdToGo = wizard.cfg.steps[stepIndexToGo];
return wizard.loadStep(stepIdToGo, stepIndexToGo, false); // next
}
var seasonVal = document.getElementById('manageTournament:name_season_input').value;
var dateFromVal = document.getElementById('manageTournament:dateFrom_input').value;
var dateToVal = document.getElementById('manageTournament:dateTo_input').value;
/*var compNameVal = document.getElementById('manageTournament:title_input').value;*/
var isValidName = validateFieldsInOtherTournament('manageTournament', ['title'], lang);
if (isValidName) {
if (validRuContentT) {
var filledBothDate = (dateFromVal != "" && dateToVal != "");
var isEmptySeason = ("" != String(seasonVal));
if ( filledBothDate || isEmptySeason) {
var currentStepIndex = wizard.getStepIndex(wizard.getState().currentStep),
stepIndexToGo = currentStepIndex + 1;
var stepIdToGo = wizard.cfg.steps[stepIndexToGo];
return wizard.loadStep(stepIdToGo, stepIndexToGo, false); // next
}
}
}
var currentStepIndex = wizard.getStepIndex(this.getState().currentStep),
stepIndexToGo = currentStepIndex;
var stepIdToGo = wizard.cfg.steps[stepIndexToGo];
return wizard.loadStep(stepIdToGo, stepIndexToGo, false); //competitionId
}
How I can return in onnext function tab of wizard?

I did something like this:
public String onFlowProcess(FlowEvent event)
{
if (!event.getOldStep().equals("competitionId"))
{
return event.getNewStep();
}
if (validationPassed())
{
return event.getNewStep();
}
else
{
return event.getOldStep();
}
}
private boolean validationPassed()
{
// do your validation here.
// return true if validation passed
}
Then in my wizard: flowListener="#{myBean.onFlowProcess}"
