One more thing I noticed testing, maybe you can take a look: rgba and
rgb0 format is not working (I used the V1 SDK), only audio frames are
received, but no apparent error is shown. On the other hand, bgr0 and
bgra formats do work. If you can't fix it then rgba and rgb0 formats
should be removed from the supported formats. Also please make the
docs in sync with the format support changes, I think it now only
mentions uyvy422.
i think it is related to:
+ /* Create receiver description */
+ recv_create_desc.color_format = NDIlib_recv_color_format_e_UYVY_RGBA;
+ recv_create_desc.bandwidth = NDIlib_recv_bandwidth_highest;
+ recv_create_desc.allow_video_fields = ctx->allow_video_fields;
i will try to check against v1 and v3 SDK...
it is not related to code above. it seems a bug in v1.
not working with v1:
ffmpeg -loop 1 -r 25 -i /usr/local/src/NDI/NDI.Image.png -vf
"format=pix_fmts=bgr0" -f libndi_newtek -y png_bgr0
ffmpeg -loop 1 -r 25 -i /usr/local/src/NDI/NDI.Image.png -vf
"format=pix_fmts=bgra" -f libndi_newtek -y png_bgra
ffmpeg -f lavfi -i "testsrc=size=1920x1080:rate=25" -vf
"format=pix_fmts=rgb0" -f libndi_newtek -y testsrc_rgb0
ffmpeg -f lavfi -i "testsrc=size=1920x1080:rate=25" -vf
"format=pix_fmts=rgba" -f libndi_newtek -y testsrc_rgba
Ok. If it works in v3, then I guess it is OK to apply as is. Let me know
when you want me to do that.
Thanks,
Marton
