T Ok Mp4
We have a recurring issue where some of our webinar delegates have reported that they can't hear our shared videos. In all cases, we've been told the live webinar audio is ok, but some attendees lose the sound as soon as we play the uploaded MP4 video. They can see the recording ok but don't hear any audio. For the majority these recordings play ok, but it's a poor experience for the others.

The people who can not hear the audio part of the video are probably people who are using the telephone for the audio part of the webinar. The videos you play back during a webinar always use the computer speakers, if there are any.
The other issue could be a non-standard mp4 video format. Since this video does not play back the same way as regular webinar audio, you might find that some computers/devices do not decode the mp4 as well as others. We have had lots of discussions here about converting your mp4 videos to a standard format that will play back on most platforms.
Thanks @Chris Droessler. In some instances, attendees have connected using the phone but not all. Do you have any recommendations for how the MP4 is produced which might avoid this issue? We use Camtasia so there are various options for encoding but I'm not sure if these would address this issue? Many thanks.
If the issue was with the recordings I think it would affect all of the attendees, not just some of them. The audio for shared videos is played through the attendees computer using its default audio settings. It is possible that these specific attendees default audio out device was muted or unavailable.
When you upload a MP4 video and play it (everyone's computer automatically plays it through the computer speakers. So if you're in an open office everyone will hear the webcast. If you plug-in your headset you can no longer hear the sound of the video because you have to manually change how you hear it. We don't want to tell 300 people on a line how they can hear the video.
That is really more of an individual attendee computer issue. When an attendee connects a headset to their computer either by USB or a traditional 1/8 jack, their computer should automatically switch to using that audio output.
For example, on my personal Windows 10 PC, I was an attendee in a webinar and dialed into the audio using my telephone. The organizer played a YouTube video using the video share feature and the audio played through my PC speakers. When I connected my USB headset the video audio switched to the headset and the GoToWebinar software gave me the option of switching from telephone to computer audio for the webinar. When I disconnected the USB headset the video audio went back to my PC speakers until I plugged in my regular headphones with a 1/8 jack, at which point the audio was then playing through those headphones.
In My Videos folder a large majority of the clips have .FLV suffix and play OK. Some of the downloaded videos have the VLC cone displayed and are labled mp4, , and when the thumbnail is pressed the little VLC control box comes up like it is going to play, but it doesn't. I believe all the downloads play through RealPlayer and when attempting to play a just downloaded video an error message (with no details) comes up on the RealPlayer page. I show a folder for Applian FLV and Media Player on the Desktop, not sure where it came from or what it does, but think it was with the last RealPlayer update.
I hope I have explained this clearly enough and with enough detail. And like I said, some videos labled as having the mp4 format play just fine from the download. And all the videos in question played OK on YouTube and appeared to download OK, but simply won't play off the downloaded file. Not a big problem, just keeps me being able to download and store some music I like to frequently listen to.
I got busy with some other things and haven't had time to install Quicktime. How would I associate those mp4 files with it. And will Quicktime change any preferences or settings on the clips that play OK...like Flv. Avi, Wmv, etc. Is there any way to control how a clip downloads, like off of You Tube. As I said previously, many of these mp4 clips play just fine.
When I try to upload a mp4 file it automatically redirect me (although I'm not sure it's a redirection) to the form, unfilled and no error message, even if I comment the lines in case of upload failure not to load the view again or if the rest of the form is uncorrect (it should not attempt to upload the video and load the form pre-filled).Whereas for example, if I put the wrong type of file, I can see the error message ('The filetype you are attempting to upload is not allowed' for example), or if the form is wrong I can see the error of the form.Finally, I must add that I modified php.ini to authorize such big files, and that I did pretty much the same thing with a form for pictures (jpg,jpeg,png...) which works perfectly but also redirect me to an unfilled form if I try to upload a .mp4 file.Edit: I just downloaded an flv video to try, and it uploaded perfectly fine, but its size was less than 8mb (default config), and a 40mb flv file had the same problem as the mp4 file, although I changed my config in php.ini for 100mb

TikTok is the newest promising frontier in video content marketing. As of early 2019, it was the third-most-downloaded app globally, growing to 500 million users in its first year. The platform is also becoming a great place for businesses to grow.
TikTok is a more fun, informal, and relaxed social media platform than many of its predecessors, and that means you can get away with more spontaneity in your videos. Read here on when the best time is to post TikTok videos.
The first thing to consider is length. At first, TikTok videos could only be up to 15 seconds long, but the company recently extended the limit to 60 seconds when you string 4 15-second segments together.
One issue that seems more common lately is Firefox's Tracking Protection feature. When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature: Tracking Protection web link
Consider playing MP4 files in a different media player that supports the format. The best choice could be a free and open-source VLC Media Player. It is known to play almost any video file type without any issue. The media player is compatible with Windows 11.
Other than VLC, you can try Movies & TV app, DivX Player, KMPlayer, 5K Player, RealPlayer, QuickTime, etc. These media players support 5K 1080p HD/ UHD MP4 video files and are compatible with Windows 11 and Windows 10.
I'm downloading a video file ... mpeg, avi - being one of the popular formats. Now, if I am downloading it, and the download breaks in the middle of the uhm ... download, then, for example, Windows Media Player will give out some error and refuse to play it (although the file is, let's say, 98% complete). But, players like KMPlayer, or MediaPlayer Classic will play it up until that point (as the matter of fact, they can play it while it is being downloaded as well).
So, I'm interested, ... without using any means of download (download managers and alike) to secure the file is completely downloaded, how can one verify whether the video file is downloaded whole, and that it is complete ?
You can use a feature in ffmpeg video converter: if you will specify it to recode video to nothing it will just read input file and report any errors that will appear. This is a very fast process because video frames are just being read, checked and silently dropped.
You will get a full error log with some generic information about file ffmpeg will output, so this will probably require your attention, through filters can be written to perform batch check of similar files.
I liked idea of using ffmpeg -f null above, but I'd actually like to automate process of using that output. In particular, common scenario I have with my music video collection is that I have few clips which have same resolution, and I'd like to diff verification logs for those files to remove ones broken the most. 041b061a72
