Command syntax #57

Open FunkyGOK opened 9 years ago

FunkyGOK commented 9 years ago

I can playout with this command

./bmdplay -m 10 -C 0 -O 4 -f /Test_Clip.mov

Though I can not seem to get this one to work. I am interested in making a universal video player Thanks for any help.

avconv -vsync 1 -i /Test_Clip.mov -c:v rawvideo -pix_fmt uyvy422 -c:a pcm_s16le -ar 48000 -f nut -f_strict experimental -syncpoints none - | ./bmdplay -f pipe:0

You need to specify the playback device settings.

I am still at bit confused. Is it possible to decode a clip with avconv and then pipe it to ./bmdplay? Or is ./bmdplay only used to play back .bmdcapture clips?

Or maybe I am way off the subject, I am looking for a way to use VLC ( ffmpeg/avconv) to output to SDI.

Thanks for any help.

You can use directly VLC if you want, bmdplay, as explained in the README, works by piping avconv.
