 With this sample: bunny_bad_convert_to_BGRA.mkv (13 MB)

 http://sms.pangolin.com/temp/bunny_bad_convert_to_BGRA.mkv

 sws_scale either doesn't do the conversion or the converted pixels are all
 zero. sws_scale returns success.

 This file was previously named bunny_rgb_crash.mkv and you already have
 that. The crash and color ordering problems with this file have been
 fixed.

 This is the last version that did the conversion to PIX_FMT_BGRA correctly
 that I know of. Note: this version had a color ordering problem with this
 file but the conversion to PIX_FMT_BGRA worked.

 So the code for this file has gone thru some changes that fixed the
 important stuff and broke this conversion. The version tested where the
 conversion fails is:
