Paul B Mahol	dbc7f02a72	avfilter/aeval: trim last frame's number of samples to match requested duration Fixes #6181. Signed-off-by: Paul B Mahol <onemda@gmail.com>	8 years ago
Ganesh Ajjanagadde	6aaac24d72	avfilter/all: propagate errors of functions from avfilter/formats Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM). This propagates the return values. All of these were found by using av_warn_unused_result, demonstrating its utility. Tested with FATE. I am least sure of the changes to avfilter/filtergraph, since I don't know what/how reduce_format is intended to behave and how it should react to errors. Fixes: CID 1325680, 1325679, 1325678.

Stefano Sabatini	0f0f3bd1e0	lavfi: use av_default_item_name() as filter private context logger avfilter_default_filter_name() is supposed to access an AVFilterContext struct, if used with a private struct it will cause a crash since it will access fields which are non defined in the private struct.	13 years ago
Stefano Sabatini	4d6a8a2bdb	lavfi: add avfilter_default_filter_name() The function is modelled after av_default_item_name(), and will print the name of the instance filter if defined, otherwise the name of the filter. This allows to show the instance name in the log, which is useful when debugging complex filter graphs.	13 years ago

Stefano Sabatini	4d4098da00	lavfi: drop planar/packed negotiation support The planar/packed switch and the packing_formats list is no longer required, since the planar/packed information is now stored in the sample format enum. This is technically a major API break, possibly it should be not too painful as we marked the audio filtering API as unstable.	13 years ago
