Thomas Mundt	73ce8162f3	avfilter/vf_scale: set proper out frame color range Prevents that following scalers in the filter chain will do unintentional color range conversions. Fixes Ticket #5096 Signed-off-by: Thomas Mundt <loudmax@yahoo.de> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 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.

Christophe Gisquet	552faecf4b	vf_scale: conditionally override chroma position 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>	9 years ago
