* avfilter/scale: refactor common code for scaling height/width expressionsAman Gupta2017-02-02
| | | | | | | Implements support for height/width expressions in vf_scale_vaapi, by refactoring common code into a new libavfilter/scale.c Signed-off-by: Mark Thompson <sw@jkqxz.net>

* vf_scale: Detecting changes of incoming frame properties and dinamically ↵Bela Bodecs2016-01-20
| | | | | | | | | | | | | | | | | | | | | | | | evaluate width and height expressions Currently scale filter accepts expressions in its width and height parameters but evaluates them only once at init and replaces them with their actual values. Later on, if any parameter of incoming frames changes - ie those were used in the original size expressions - then they new values will not have any affect for width and heigth values. They remain the same. This patch makes possible that width and height expressions be evaluated frame-by-frame basis if width/height/sar/format properties of incoming frame would change. To retain the current behaviour and not to break any earlier app, a new config parameter has been introduced. Its name is "eval" and it has two distinct values: "init" and "frame". The default value is "init". This feature is very usefull in case of DVBT mpeg-ts streams where SAR may change time-by-time from 4/3 to 16/9 and vica-versa and the size remains the same and you want to create a variable sized output with 1/1 SAR.

* 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.

* vf_scale: conditionally override chroma positionChristophe Gisquet2015-09-23
| | | | | | | | | | For yuv420p, the chroma position is unilaterally overriden, even if ffmpeg's command-line explicitly set it. To fix this, override only if the value is the default one. Regression since 1515bfb3. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
