Hello,
I converted the original 30fps video with this command:
ffmpeg -i DSCN0798.MOV -b 45M -s 1920x1080 -vcodec dnxhd -acodec pcm_s16le
Video1.MOV
The file size grew from 86 MB to 280 MB.
I can load it into cinelerra but when I play it back there still is no sound
and after 8-10 secs cinelerra crashes.
The qtinfo command applied to the new video shows the following output.
qtinfo Video1.MOV
Type: Quicktime
1 audio tracks.
2 channels, 16 bits, sample rate 48000, length 2306048 samples, compressor

I restarted cinelerra from the command line ( I used a desktop icon of the
Unity desktop to start it before ) to check for hints to the problem:

Above line starting with "AudioALSA" looks bad to me.
Does it worry somebody else, too?
I then tried another video I had created with a different camera,
it is in AVI format with these details:
qtinfo SN850545.AVI
Type: AVI
1 audio tracks.
1 channels, 8 bits, sample rate 11025, length 885560 samples, wav_id 0x07.
Sample format: 16 bit signed.
Channel setup: Not available
Language: eng
supported.
1 video tracks.
640x480, depth 24
rate 30.000300 [1000000:33333] not constant
length 2401 frames
compressor MJPG.
Native colormodel: YUV 4:2:2 planar (jpeg)
Interlace mode: None (Progressive)
No timecodes available
supported.
0 text tracks.
This video play back fine in cinelerra, including sound!
So I must assume the coding of the video I tried first is problematic.
I hope to be able to convert it into something useful for cinelerra.
We will see.
I will keep you informed of the progress.

Betreff: Re: [CinCV] CinCV 2.2: No sound in playback
Einar,
my Alsa device in Cinelerra playback preferences is called "default".
When I drop down the list of devices I also see "HDA Intel #0" and "HDA Intel
#1".
The syslog entries I posted on IRC seem to refer to another problem.
My $HOME is below /home ( "echo $HOME" = "/home/andre" ).
I am trying to play videos in cinelerra which I created with my camera,
they are 1920x1080.
Here is the output of "qtinfo DSCN0798.MOV"
Type: Quicktime
1 audio tracks.
2 channels, 16 bits, sample rate 48000, length 2306048 samples, compressor
mp4a.
Sample format: Floating point.
Channel setup: Front Left, Front Right
Language: eng
supported.
1 video tracks.
1920x1080, depth 24
rate 29.970030 [30000:1001] constant
length 1440 frames
compressor avc1.
Native colormodel: YUV 4:2:0 planar (jpeg)
Interlace mode: None (Progressive)
No timecodes available
supported.
0 text tracks.
I will try to convert them following the information at
http://www.g-raffa.eu/Cinelerra/HOWTO/get_media_ready.html
and will post the results here.
Thanks.
Andre
