| | | | | | | | | | | | Commit bf0d2d6030c239f91e0368a20fb2dc0705bfec99 introduced av_warn_unused_result to avfilter/formats, whose associated warnings were mostly fixed in 6aaac24d72a7da631173209841a3944fcb4a3309. This fixes the issues in avfilter/avfiltergraph. Tested with FATE. Reviewed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>

* avfilter/formats: add av_warn_unused_result to function prototypesGanesh Ajjanagadde2015-10-14
| | | | | | | | This uses the av_warn_unused_result attribute liberally to catch some forms of improper usage of functions defined in avfilter/formats.h. Reviewed-by: Nicolas George <george@nsup.org> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
* avfilter/all: propagate errors of functions from avfilter/formatsGanesh Ajjanagadde2015-10-14
| | | | | | | | | | | | | | | | | | 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.

* avfilter/delogo: Set default band to 1Jean Delvare2015-10-08
| | | | | | | | | | | | | | | | | | | | | | | | | | The original interpolation algorithm behaved poorly on the borders and did not even guarantee continuity at the borders. For this reason, a second interpolation/blending pass was required on the borders to make them seamless. However, since the interpolation algorithm was improved in June 2013, the border issues no longer exist. The new algorithm does guarantee continuity at the borders, making the second pass useless. A larger band always increases the cumulated interpolation error. In most cases it also increases the average interpolation error, even though the samples in the band are only partially interpolated. For this reason I would like to get rid of the "band" parameter. As a first step, let's change its default value from 4 to 1 and document it as deprecated. I have benchmarked this change on a combination of input sources and realistic logo areas. Lowering the band value from 4 to 1 resulted in 8 to 39 % less interpolation error per frame (or 1 to 34 % less interpolation error per luma sample.)
