when trying to record mp4 H264 i got this : System.IO.IOException: Pipe is broken !!

[adamtigerking]

its happen everytime i hit record , the software wait like a 2 seconds then pop this error to me and stop recording :

System.IO.IOException: Pipe is broken.

[MathewSachin]

Seems like NVENC is not supported on your system.
Do you have an NVIDIA graphic card? If not, use the x264 mp4 encoder.
If yes, please provide its model number so i can check if it supports NVENC.

[adamtigerking]

i have ATI radeon HD 4350 video Card , so the H264 only work with NVIDIA cards ?

[MathewSachin]

No, use the first encoder in the list using x264 encoding. It is H.264.

[adamtigerking]

- yet another error when using x264 :

System.IO.IOException: Insufficient system resources exist to complete the requested service.

Please provide your system specifications: CPU & RAM.

It seems to me that Captura is unable to capture at the specified fps on your system.

[MathewSachin]

Please try using the MF writer in latest Beta release. It is a hardware based H.264 encoder and performs better than when using with FFmpeg.
