Unsplitting two video files with ffmpeg [duplicate]
2 septembre 2016, par exebookThis question is an exact duplicate of :
I cannot find a better word for this, because I searched for "combine", "join", "merge", "concat" and each time I get the information on how to get two videos into one so that the resulting file will play first video and then continues to the second one. I, on the other hand, need them to play simultaneously in the resulting video, so that first file goes to the left, and the second one to the right. It is a video chat recording of two person web cameras that need to get into one file to play at once. How to do that with ffmpeg ?

Tips for encoding a live stream to IIS Media Services (or Azure Live Media Services) with FFMPEG ?
6 mars 2014, par user3104748We're trying to encode assets, either live or static, in a live stream to IIS Media Services using ffmpeg. Can anyone provide pointers for exactly what kinds of parameters we should be using and setting ?
As part of our test, just to see if we can get things to work, we have a standard plain-old MP4 video static asset that we're trying to stream to the server. It seems to work on the client side, but when we try to view the video on the receiving end, we get nothing.
Here's an example of the command we're using, where gg.mp4 is the static MP4 video (obviously (hostname) is the name of our host and not the actual word in parenthesis :)...
ffmpeg -y -re -i gg.mp4 -movflags isml+frag_keyframe -f ismv -threads 0 -c:a libvo_aacenc -ac 2 -b:a 64k -c:v libx264 -preset fast -profile:v baseline -g 48 -keyint_min 48 -map 0:v -b:v:0 477k -s:v:0 368x152 -map 0:v -b:v:1 331k -s:v:1 288x120 -map 0:v -b:v:2 230k -s:v:2 224x92 -map 0:a:0 http://(hostname)/ingest.isml/Streams(video)

How to use ffmpeg with h.265 (or h.264) coded ?
8 mai 2015, par randomuser1Normally I start recording the camera image with the command :
ffmpeg -y -f vfwcap -r 25 -i 0 OUT.mp4
but I’m not sure which coded do I use in here (I’m just beginning my adventure with ffmpeg), however I found on this webpage this command :
ffmpeg -i INPUT -c:a copy -x265-params crf=25 OUT.mov
But when I run it - I get the following error :
INPUT: No such file or directory"
I changed the INPUT word above also to
0
, so the command isffmpeg -i 0 -c:a copy -x265-params crf=25 OUT.mov
,
but error stays similar (0: no such file or directory
).
How can I grab the camera image and save it to a file while using the H.265 ?
