Hi Mark
I never managed to use the internal H264 encoder properly.
I export with a yuv4mpeg pipe
Here is the script I am using
#/bin/bash
file=$1.264
mkfifo stream.y4m
x264 --sar 1:1 -m 6 --me umh -b 4 --bitrate 24000 --threads 4 -o $file
stream.y4m &
sleep 0.5
cat /dev/stdin > stream.y4m
rm stream.y4m
That will give you the 264 video
You can export the sound to AC3
Then mux the lot with MP4 tools
#!/bin/bash
fps=$1
IFS=$(echo -e "\n\r\t")
for nom in $(ls *.264) ; do
echo "Traitement de ${nom}"
MP4Box -add "${nom}" -flat -add "$(basename ${nom} .264).ac3"
-fps "$fps" "$(basename ${nom} .264).mp4"
done
The fps is here for me to work on different frame rate as I am scanning
films.
Cheers
E.
