when i am running this code libffmpeg.so is not building.
secondly error is coming : /home/samo/Downloads/android-ndk-r10e/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-ld : ,noexecstack : unknown -z option

Can someone explain me the two lines after ’make install’. What are those two lines doing. I dont know the scripting so pls elaborate what d and -z terms doing. Thanx

How to stack several videos using ffmpeg ?

13 juillet 2019, par John
I have four cameras that are recording videos and wand to stack all videos into one video file. The final video must be a 2x2 grid.

THE HARD PART is that sometimes cameras are not recording simultaneously.

Here you can see one situation of how cameras are recording :
```
Camera 1 timeline: |recording....................................|

Camera 2 timeline: |stopped....|recording........................|

Camera 3 timeline: |recording.........|stopped....|recording.....|

Camera 4 timeline: |recording..................|stopped..........|
```
Explanation :
- Camera 1 is recording all time.
- Camera 2 is starting recording later.
- Camera 3 is recording, then stopped a period of time, then again recording.
- Camera 4 is recording a period of time, then stopped.
In the final video I want to synchronize each video by timestamps.

If a camera is stopped a period of time then at its position must be a black portion.

How can I do this ?

Streaming trouble, ffmpeg unable to find a suitable output format

9 octobre 2018, par Michael Munyanyi

FFMPEG for some odd reason won’t allow me to output a stream, it’s odd because I have two computers available and one, which had low CPU was having trouble decoding but the stream worked, so I switched my network cables and I have tried transcoding with the same command and it will not output a stream.

My command reads

ffmpeg -i udp://@xxx.x.x.xx.xxxx -f mpegts udp://@xxx.x.x.xx.xxxx

I also tried

ffmpeg -i udp://@xxx.x.x.xx.xxxx udp://@xxx.x.x.xx.xxxx

The error reads

[NULL @ 000001c95eeb2600] Unable to find a suitable output format for udp://@xxx.x.x.xx.xxxx'

udp://@xxx.x.x.xx.xxxx: Invalid argument"
