YUV input through FIFO is failing
Posted: 13 Feb 2015 23:16
Trying to input live YUV data through a FIFO into VLC. For testing I have YUV data in a file 'TEST.yuv', if I play this in VLC, it works. If I try to send it through a FIFO 'out.yuv', it fails. The relevant log portion is:
My relevant steps are:
mkfifo out.yuv
cat TEST.yuv > out.yuv
vlc --demux rawvideo --rawvid-fps 30 --rawvid-width 1920 --rawvid-height 1080 --rawvid-chroma I420 out.yuv
If I also cat the FIFO (to keep it alive), VLC does play the file, but it is garbled... so it seems like its something with the initial synchronization.
