Hi

yesterdays merge brought in some ABI issues

first is libav adding a "buffersink" libavfilter/buffersink.c which seems based on a old version of our buffersink vs. our libavfilter/sink_buffer.c

second is that libav introduced our avfilter_get_audio_buffer_ref_from_arrays() with different API ive added that temporary under a new name to be able to finish the merge quickly

can someone (nicolas? stefano?) maybe look into a technical solution/ workaround to this? maybe a configure switch so that the user can decide at compile time if he needs to be compatible to the debian ABI

maybe someone could speak with libav about these issues. It really seems becoming a bit ridiculous that they copy our code and slightly change API while keeping the function names just to break compatibility daemon404 interrested in trying ?

also setting the sink pixfmt has changed in the merge, the new libav way seems a complicated mess (needs more lines of code for user apps and is structurally more complex as it needs an additional filter). Any comments here ? should we just change it back or come up with another system that somehow merges the ideas? Maybe it could make sense to have a char* based pixfmt list, that is in relation to the user setting it as command line option in some case?

PS: i would have written that yesterday but my internet connection died yesterday and just started working again now ...

The bravest are surely those who have the clearest vision of what is before them, glory and danger alike, and yet notwithstanding go out to meet it. -- Thucydides -------------- next part -------------- A non-text attachment was scrubbed...
