Note that MP4 is usually encoded with different audio codecs like WMA, LPCM, DTS-HD, MP3, AAC, AC-3, Opus, etc. If you play the video with media player apps that do not have a supported audio codec, it may pose an 'MP4 no sound' problem. This means that functions like sound may be affected. If your MP4 media file doesn't have the right codec associated with it, this could affect the media file's function. You should know the major reasons why MP4 files usually have this problem to figure out which of the factors apply to your case. An MP4 video without sound is a video that goes mute when you open it, even though the video might be playing. What does 'MP4 no sound' mean? As the statement implies, an MP4 file that has refused to play audio when you play the video file is said to have 'no sound.' This means that the MP4 file has not been able to synchronize the video and audio so that both will play and at the same time. Part 1: Overview of MP4 No Sound Problems 1.

Using that resource wantonly can seriously inconvenience or, at worse, put lives at risk. Whether itвЂ™s double checking for bugs or treating your users with respect, itвЂ™s important to remember that a mobile deviceвЂ™s battery is a finite resource. For what itвЂ™s worth, IвЂ™ve heard that thisВ was, as stated, a bug. Either way, attention was brought to it and itвЂ™s fixed now. IвЂ™m not gonna pass any judgments here - bugs happen all of the time and itвЂ™s not fun to get pilloried over a simple mistake. If you donвЂ™t believe him, it was a thing Facebook was doing to make their app work a way they wanted it to but Apple didnвЂ™t and they got caught. So if you believe Grant, this is a simple bug.

A popular storage companyВ used it at one point to keep their app open to grab new photos to upload (before it switched to using вЂknown locationsвЂ™ to wake the app up).ДЄnd IвЂ™m aware of a bunch of other devs that have used the trick in one fashion or another to get their apps to do something Apple didnвЂ™t want them doing - things likeВ leaving an app open constantly in the background to pre-load content or advertising, to upload or download files or the news feed or more auto-playing videos. Our fixes will solve this audio issue and remove background audio completely.ДЇor context, using background audio (via the VoIP calling entitlement) to keep an app awake is an old standard in the app kludge world. The app isnвЂ™t actually doing anything while awake in the background, but it does use more battery simply by being awake. This is similar to when you close a music app and want to keep listening to the music while you do other things, except in this case it was unintentional and nothing kept playing. If you leave the Facebook app after watching a video, the audio session sometimes stays open as if the app was playing audio silently. The second issue is with how we manage audio sessions. The version released today has some improvements that should start making this better. This repeated processing causes our app to use more battery than intended. A CPU spin is like a child in a car asking, вЂњAre we there yet? Are we there yet? Are we there yet?вЂќwith the question not resulting in any progress to reaching the destination. The first issue we found was a вЂњCPU spinвЂќ in our network code. Grant says this was unintentional, and that it was not being used to keep the app alive - yet it did as a byproduct of the bug. The other issue, that Facebook was running a silent audio stream in the background, is also called out.

That fix came today in an update to Facebook that should be available on your iOS device (though you wouldnвЂ™t know it from their release notes).

Grant says that the battery issues were caused by a series of bugs including one that ate up extra CPU cycles, causing Facebook to use up more of your iPhone battery than it should.ДЄfter a post by Circa co-founder Matt GalliganВ and followups by Federico ViticciВ and Nick Heer caused some eyeballs to hit the issue, Facebook told us that it was looking into the problem and that it would put out a fix soon.

Facebook engineering manager Ari Grant has posted an explanation for the recent issues with the app gorging itself on power.
