In gmerlin_avdecoder I have backwards compatibility functions,
which were easy enough to implement.
The gmerlin plugin API itself changes a lot. But in my opinion it's worth
it because the stuff becomes much simpler. As an example, the old audio
filter API had 4 functions like:
void (*connect_input_port)(void * priv, bg_read_audio_func_t func,
void * data,
int stream, int port);
void (*set_input_format)(void * priv, gavl_audio_format_t * format, int
port);
void (*get_output_format)(void * priv, gavl_audio_format_t * format);
bg_read_audio_func_t read_audio;
Which is replaced in the new API by one single function:
gavl_audio_source_t * (*connect)(void * priv, gavl_audio_source_t *,
const gavl_audio_options_t * opt);
with the side effect, that you no longer need to convert the samples to
a format required by the filter as this is done implicitly.
You can easily build a chain of arbitrary modules (e.g. filters of whatever)
by doing a sequence like:
gavl_audio_source_t * src = get_primary_source();
src = connect_module_1(module1, src);
src = connect_module_2(module2, src);
if(use_module_3)
src = connect_module_3(module3, src);
