Hello Akmal,

I have faced issues with capabilities of x264enc and muxer.
I would suggest you to remove avimux and dump encoder output to a file.

gst_parse_launch("autovideosrc ! video/x-raw,width=640,height=480,framerate=30/1 ! 

tee name=tsplit ! x264enc qp-min=18 !filesink location=output.mp4 

and output.mp4 should be playable using ffmpeg / vlc player  

Worth a try or you can even change avimux with other options flvmux.

Cheers,

Kiran

Hello everyone,

I'm currently coding on Visual Studio 2017 on Windows 10 to create a program using gst_parse_launch to save a webcam video with filesink. The pipeline is as follow :

gst_parse_launch("autovideosrc ! video/x-raw,width=640,height=480,framerate=30/1 ! 

tee name=tsplit ! x264enc qp-min=18 ! h264parse ! avimux ! 

filesink location=output.mp4 tsplit. ! 

queue ! matroskamux ! queue leaky=2 ! 

tcpserversink host=192.168.1.203 port=7001", NULL);

I've encountered a problem where I couldn't read/play a video output file created by the program written on C++ and by lauching ffprobe.exe to this file, I have no information at all bout the file. However, if I launch the same pipeline on command prompt and on Windows PowerShell, the video output file could be read perfectly and by lauching ffprobe.exe to this file, I have all the informations about this file. 

I hope someone can help me with this. Thanks in advance !
