FFmpeg with --enable-omx --enable-omx-rpi
« on: June 20, 2018, 04:43:49 AM »
Hi,
I'm trying to build FFMpeg with omx support.
However i keep running into that issue when i try to compile :

Code: [Select]
./configure: line 1: pr: not found
./configure: line 1: pr: not found
./configure: line 1: pr: not found
./configure: line 1: pr: not found
./configure: line 1: pr: not found
./configure: line 1: pr: not found
./configure: line 1: pr: not found
./configure: line 1: pr: not found

I've tested all the versions :
3.1.3 (that is in tc repo)
3.4.1
3.4.2

All the same issue.
I think i'm missing something.
Any hint ?

Use the apps gui to find which extension provides pr - from memory it’s coreutils

Now i'm facing an odd issue:

Code: [Select]
CC      libavcodec/omx.o
libavcodec/omx.c: In function 'omx_encode_init':
libavcodec/omx.c:689:34: error: 'OMX_BUFFERFLAG_CODECCONFIG' undeclared (first use in this function); did you mean 'OMX_BUFFERFLAG_DECODEONLY'?
             if (buffer->nFlags & OMX_BUFFERFLAG_CODECCONFIG) {
                                  ^~~~~~~~~~~~~~~~~~~~~~~~~~
                                  OMX_BUFFERFLAG_DECODEONLY

                              OMX_BUFFERFLAG_DECODEONLY
make: *** [ffbuild/common.mak:60: libavcodec/omx.o] Error 1

Someone has any good idea ? :D
