Comskip Support Forum

Hi,

I am new to Comskip and am trying to compile on Debian 8.9. I have put in all the dependencies and build ffmpeg. Also put the dependencies and completed the configure on the Comskip.

When I run the make I get the error

mpeg2dec.c57: error: ‘CODEC_FLAG_GRAY’ undeclared (first use in this function)
if (!hardware_decode) is->video_st->codec->flags |= CODEC_FLAG_GRAY;

I know I am missing something but cant' quite figure out where or what declares this.

For the configure of Comskip I am using the command below otherwise i am just following the instructions to compile from the git hub.

PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure --bindir="$HOME/bin"

many thanks for any help

Sorry I found my own issue and resolution. I think the define CODEC_FLAG_GRAY comes from the ffmpeg, I am compiling from the git hub version which has defined AV_CODEC_FLAG_GREY

I added the lines below to mpeg2dec.c and it is compiling correctly. I am assuming that there was a change in the later versions of ffmpeg.

#ifndef CODEC_FLAG_GRAY
#define CODEC_FLAG_GRAY AV_CODEC_FLAG_GRAY
#endif

They actually made that change about 2 years ago.
