Launching ffmpeg from inside my C code doesn't convert video stream from fifo

13 mai 2017, par abraxas1

(Beaglebone Black, ubuntu 16.04 linux 4.4.62-ti-r99)

I have a raw h264 feed coming into my C program (into a callback from a custom API) and then I named-piped the raw h264 to a file and this CLI command converts that file successfully.

ffmpeg -report -re -framerate 30 -y -f h264 -i orbi_0148.cam1.h264 -c:v copy -an -video_size 1920x1080 -f mp4 orbi_0148.cam1-1.mp4

I then try to launch this command from my program with the same options using execv(),

first mkfifo the fifo’s,

then launch ffmpeg (shown below) starts the streaming form the cameras to my callback function, and out to the fifos.

I close the fifos at the end of video recording, and don’t get any file created and get this output, which I don’t understand at all.
(the successful command line output follows below this output generated from execv())
thanks, any help much appreciated.
hardware has come in now and the spot light is on me.

(execv output with options -report -y -i /tmp/fifocam3.h264 -c:v copy -an -video_size 1920x1080 -f mp4 /media/sd-card/orbi_0140.cam3.mp4)

It succeeds greatly but the only thing I noticed is :

it seems to apply transcode (decode & encode again) to the output implicitely ?
