Hi. When I try to compile the following line of code
av_channel_layout_copy(&c->ch_layout,
&(AVChannelLayout)AV_CHANNEL_LAYOUT_STEREO);
taken from mux.c example I obtain the error:
/home/denis/Cpp/ffmpeg-6.0/libavutil/channel_layout.h:362: *error: taking
address of rvalue [-fpermissive]*
../../ffmpeg-6.0/libavutil/channel_layout.h:362:5: error: taking address of
rvalue [-fpermissive]
362 | { .order = AV_CHANNEL_ORDER_NATIVE, .nb_channels = (nb), .u = {
.mask = (m) }}
|
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../../ffmpeg-6.0/libavutil/channel_layout.h:369:45: note: in expansion of macro
‘AV_CHANNEL_LAYOUT_MASK’
369 | #define AV_CHANNEL_LAYOUT_STEREO AV_CHANNEL_LAYOUT_MASK(2,
AV_CH_LAYOUT_STEREO)

../ffmpegTest/main.cpp:157:65: note: in expansion of macro
‘AV_CHANNEL_LAYOUT_STEREO’
157 | av_channel_layout_copy(&c->ch_layout,
&(AVChannelLayout)AV_CHANNEL_LAYOUT_STEREO);
|
^~~~~~~~~~~~~~~~~~~~~~~~
How can I translate it to work in Windows, Linux and Mac?
Something like this?
AVChannelLayout a= AV_CHANNEL_LAYOUT_STEREO;
av_channel_layout_copy(&c->ch_layout, &a);
