Dear community,
I am doing a video processing project with opencv and I have to read and write video/audio streams with ffmpeg. I found the ffmpeg-output-example useful, but I had a tough time to update it (I don't know the code is not updated while some parts of the code is deprecated!). I have uploaded my working code in: https://github.com/falahati1987/video/blob/master/ffmpeg-example.cpp
When I run the code, I get the following error:
[libx264 @ 0xee2400] broken ffmpeg default settings detected [libx264 @ 0xee2400] use an encoding preset (e.g. -vpre medium) [libx264 @ 0xee2400] preset usage: -vpre <speed> -vpre <profile> [libx264 @ 0xee2400] speed presets are listed in x264 --help [libx264 @ 0xee2400] profile is optional; x264 defaults to high
My sample video specifications is :
Output #0, mov, to '/home/dfalahati/Videos/melissa.MOV': Stream #0:0: Video: h264, yuv420p, 352x288, q=2-31, 400 kb/s, 25 tbc Stream #0:1: Audio: aac, 44100 Hz, 2 channels, 64 kb/s
And I am using ffmpeg 2.8.11 on Ubuntu 16.04. I have not compiled ffmpeg from source.
can anybody help me?
Wrong mailing list. ffmpeg-user is questions involving the FFmpeg cli tools (ffmpeg, ffplay, ffprobe, ffserver). Usage questions involving the FFmpeg libraries should be asked at libav-user. That being said, you are using the 2.8 branch but apparently you are using code and Doxygen from the 0.6 branch. I believe output-example.c was renamed to doc/examples/muxing.c. If you have more questions please ask at libav-user.
