YUV input through FIFO is failing

[jdwiegman]

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:

Code: Select all

[0x7f31400009b8] main input debug: creating access 'file' location='MYPATH/out.yuv', path='MYPATH/out.yuv' [0x7f31380010f8] main access debug: looking for access module matching "file": 25 candidates [0x7f31380010f8] filesystem access debug: opening file `MYPATH/out.yuv' [0x7f31380010f8] main access debug: using access module "filesystem" [0x7f3138001248] main stream debug: Using stream method for AStream* [0x7f3138001248] main stream debug: starting pre-buffering [0x7f3138001248] main stream error: cannot pre fill buffer [0x7f31380010f8] main access debug: removing module "filesystem" [0x7f31400009b8] main input warning: cannot create a stream_t from access

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.
