ivtv streams for direct input to dvdauthor, audio but no video
|
|
My goal is to create a DVD of a church service as painlessly as possible.
I am running a P4 with debian 6.0,
Linux version 2.6.26-2-686 (Debian 2.6.26-26lenny1)
dvdauthor-0.6.1.8 (which claims to have the ivtv patch applied)
I have tried patching dvdauthor-0.6.1.1 with the same results, tried version
0.7 as well
I can create the DVD, but a DVD player plays the audio but no video,
xine. vlc, mplayer all work with the raw DVD, and mpeg files, I can fix the
issue if I pass the video through ffmpeg -target ntsc-dvd,
here is the script I am using for testing
record.sh
--------------------------------------------------------------------------------
#v4l2-ctl --set-input=1
#v4l2-ctl --set-fmt-video=width=720,height=480 --set-standard=ntsc
#v4l2-ctl
--set-ctrl=stream_type=3,audio_layer_ii_bitrate=11,video_bitrate=12000000,video_peak_bitrate=14000000
#v4l2-ctl --set-ctrl=stream_vbi_format=1
v4l2-ctl -i 1
v4l2-ctl -s ntsc
v4l2-ctl -c stream_type=3
v4l2-ctl -c insert_navigation_packets=0
v4l2-ctl -c stream_vbi_format=0
v4l2-ctl -c video_aspect=1
#v4l2-ctl -c video_bitrate=2750000
v4l2-ctl -c video_bitrate=5000000
v4l2-ctl -c video_peak_bitrate=7000000
v4l2-ctl -c video_gop_size=15
v4l2-ctl -c video_b_frames=2
v4l2-ctl -c video_gop_closure=1
v4l2-ctl -c audio_sampling_frequency=1
v4l2-ctl -c audio_encoding_layer=1
#v4l2-ctl -c audio_layer_ii_bitrate=11
v4l2-ctl -c audio_layer_ii_bitrate=10
v4l2-ctl -c audio_stereo_mode=0
v4l2-ctl -c audio_emphasis=0
v4l2-ctl -c audio_crc=0
rm ivtv.mpg
rm DVD/* -Rf
sleep 2;
cp /dev/video0 ivtv.mpg &
pid=$(ps ax | grep "cp /dev/video0" | grep -v ' grep ' | awk '{print $1}')
## This works but requires a faster machine
#ffmpeg -i /dev/video0 -target ntsc-dvd ivtv.mpg &
#pid=$(ps ax | grep "ffmpeg -i /dev/video0" | grep -v ' grep ' | awk '{print
$1}')
echo "Creating 60 second video on the pid $pid";
sleep 360;
kill -9 $pid;
## this command will fix video with ffmepg
#ffmpeg -i video0.mpg -target ntsc-dvd ivtv.mpg
dvdauthor -o DVD -x dvd.xml
growisofs -Z /dev/sr0 --dvd-video --dvd-compat DVD
------------------------------------------------------------------------------------------------------
