I have this working…meaning, it starts, but rapidly fails after a few moments. Here’s my current command line: bmdcapture -C 0 -m 14 -V 3 -A 2 -F nut -f pipe:1 | avconv -y -i - -copytb -c:v libx264 -c:a aac -ar 44100 -strict experimental -s 640x360 -b:a 160k /pub/video/"$SHOW"_$TIME.mp4 -f flv -c:v libx264 -c:a aac -ar 22050 -strict experimental -s 384x216 -b:a 64k rtmp://live.mysite.com/myapp/video But it fails after some moments with this error: Stopping Capture 22 q=28.0 q=31.0 size= 5138kB time=62.48 bitrate= 673.6kbits/s Failed to update header with correct duration.0kB time=62.96 bitrate= 672.7kbits/s [flv @ 0x248b7c0] Failed to update header with correct file size. Any clues as to what this is?
