What Video and Audio Formats Does Facebook Messenger Support?

It will accept uploads in any format and codec that FFmpeg can process, which is pretty much anything except AVI files with non-standard encodings. It converts whatever is uploaded to MPEG-4 h.264 baseline at a standard resolution and bitrate, and that's what it stores and distributes.

Download HitFilm Express - Free editing and VFX software - fxhome.com It does a range of output renders to match all forms of social media and you can create projects in any format, even that dreaded Vertivision so liked by IGram . ..Do not worry about FLV. What Adobe phasing out SWF and FLV means for video translation If you have a weird and momentary need to use it, then there are plenty of free on-line file converters to choose from. But, as the article says, there are now better compression formats available

3. Make terminal alias, to group video and audio setting changes, for using a/v receiver

I would possibly write a short bash script to include both. You have to know your displays' and sinks' names prior to writing it.To see your displays use xrandr -q command, to find your sinks use pacmd list-sinks commandThe scriptNow as you run the script, pressing 1 will make the desired changes and 2 will reset them. Run the script with its path or add it to $PATH environment variable. It's possible to create aliases too. Hope this was even close to the solution you wanted.NOTE changing the output sink via command line may only take effect if stream target device reading is disabled. It can be done by editing the corresponding line in /etc/pulse/default.pa to:

I have heard it called a "Buffering Bar" on many occasions. Dave is right though in saying that it will vary from person to person

7. How do I transfer folders video audio programs etc. from my laptop to my desktop and vice versa?

Once you do connect a dual end USB cable, look under "My Network" in Windows Explorer (NOT "My Computer"). If the other computer appears in "Computers near me", then you should be able to transfer files back and forth with a click-and-drag. I can not say for sure it will work, but it wo not hurt to try. And below, I tell you this last in case you do not have or can not afford one; few things are as annoying as jerks telling you to spend money you do not have. A USB 2.0 flash RAM device will also do the trick; you can even use your MP3 player if it connects through a USB cable. If you can afford a flash RAM device, they are worth the money (about US$20); mine is only 128MB, and it's still more than I usually need. .
