I am trying to convert a raw video captured using a Logitech USB Cam(YUYV) to mp4 using avconv. I have tried the below to do so:
avconv -i out.raw -c copy output.mp4
avconv -i out.raw -vcodec copy -acodec copy output.mp4
but I get an error as shown below.
root@beaglebone:~/BBB_CV/boneCV# avconv -i out.raw -c copy output.mp4
avconv version 11.9-6:11.9-1~deb8u1, Copyright (c) 2000-2017 the Libav developersbuilt on Apr 23 2017 23:00:54 with gcc 4.9.2 (Debian 4.9.2-10)
out.raw: Invalid data found when processing input
I have checked here, but did not find any relevant examples for the above purpose.
Edit: Added more details--
I tried doing the below by adding the infile options as suggested:
root@beaglebone:~/BBB_CV/boneCV# avconv -s 640x480 -framerate 30 -pix_fmt yuyv422 -f rawvideo -i out.raw -c copy output.mp4
This got me rid of the previous error and some new ones popped up as shown below.

Since the input is raw, avconv doesn't know input properties. It needs to register those into the MOOV box of the MP4 it creates. So, before -i out.raw, you need to specify -s WxH -framerate N -pix_fmt P where the values should be substituted in. YUYV will usually be yuyv422.
