The rgtc1u_block function places the single channel value in every channel except the alpha channel The pixel format you have chosen is one which disregards the alpha channel The output of this alpha-only decoder should be in the alpha channel of a pixel format which carries alpha. Probably other channels should have zero values. > On 23 Sep 2017, at 20:52, Martin Vignali <martin.vign...@gmail.com> wrote: > > Sorry, i made a mistake in the previous patchs > > Correct patchs in attach > > Martin > <0001-libavformat-add-mov-dataformat-tag-for-HapAlphaOnly-.patch><0002-libavcodec-hapdec-add-support-HapAlphaOnly.patch>_______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > http://ffmpeg.org/mailman/listinfo/ffmpeg-devel _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
