If I wanted to play a video stream over the network but the video and audio are separated into two different URLs, can I use FFMPEG to stream merge those two sources? Because waiting for FFMPEG to merge both files into a single local file will probably take sometime which wouldn't be nice for the user experience.

I am trying to covert a video to h.264 format. I can save the new video to a normal directory but saving the new video to a Windows temp file fails. However I can manage to save a snapshot image from the video into Windows temp folder without problem. I cannot figure out what is the problem?

When extracting Audio streams using ffmpeg from containers such as MP4, how does ffmpeg increase bitrate, if it is higher than the source bitrate?
An example might be ffmpeg -i video.mp4 -f mp3 -ab 256000 -vn music.mp3. What does ffmpeg do if the incoming bitrate is 128k? Does it interpolate or default to 128k on the output music.mp3? I know this seems like not a so-called "programming question" but ffmpeg forum says it is going out of business and no one will reply to posts (...)

CMake cannot find FFmpeg even though everything is right setup. I used vcpkg to install ffmpeg
I can't find any information to setup ffmpeg with CMake. I'm on Windows 10 with Visual Studio.
Get findFFMPEG and put in ffmpeg folder but doesn't solve the issue. change the folder name to
FFMPEG capital letters but still doesn't solve the issue.
I get this error:
