## enc_avc_file
2+
3+
The enc_avc_file sample shows how to convert a raw YUV video file to a compressed H.264 video file.
4+
5+
### Command Line
6+
7+
enc_avc_file --frame <width>x<height> --rate <fps> --color <COLOR> --input <file.yuv> --output <file.h264>
8+
[--colors]
9+
[--help]
10+
11+
### Examples
12+
13+
The following command encodes a raw YUV video from `foreman_qcif.yuv` to a H.264 video in `foreman_qcif.h264`:
14+
15+
./enc_avc_file --frame 176x144 --rate 30 --color yuv420 --input ../assets/vid/foreman_qcif.yuv --output foreman_qcif.h264
16+
17+
and using default option:
18+
19+
./enc_avc_file
20+
21+
***
22+
23+
mac:~/AVBlocksSDK.macosx/lib$ ./enc_avc_file
24+
25+
Using defaults:
26+
enc_avc_file --input ../assets/vid/foreman_qcif.yuv --output foreman_qcif.h264 --rate 30 --frame 176x144 --color yuv420
27+
Transcoder open: Success
28+
Transcoder run: Success
29+
Transcoder close: Success
