[FFmpeg-user] ffenc_bmp encode issue

[Carlos Aguero]

Hi all,

I am trying to grab a frame and encode it as a bmp file, grayscale, 
8bits, if I use the ffenc_pgm I get a grayscale png file as expected, 
but when I use the ffenc_bmp encoder the result is a dark bmp file, any 
suggestions? or is there a problem with the bmp encoder?

*I am using this pipeline for png encode (working fine)*
gst-launch v4l2src always-copy=false chain-ipipe=true num-buffers=1 ! 
'video/x-raw-yuv, width=(int)640, height=(int)480, 
framerate=(fraction)30/1' ! ffmpegcolorspace ! 'video/x-raw-gray, 
width=(int)640, height=(int)480, framerate=(fraction)30/1, bpp=(int)8, 
depth=(int)8' ! ffenc_pgm ! filesink location=test.png

*and this one for bmp encoding (not working)*
gst-launch v4l2src always-copy=false chain-ipipe=true num-buffers=1 ! 
'video/x-raw-yuv, width=(int)640, height=(int)480, 
framerate=(fraction)30/1' ! ffmpegcolorspace ! 'video/x-raw-gray, 
width=(int)640, height=(int)480, framerate=(fraction)30/1, bpp=(int)8, 
depth=(int)8' ! ffenc_bmp ! filesink location=test.bmp
