Hi all,
my problem is solved now. See my findings below.
I fixed the sound by running this command:
ffmpeg -i DSCN0798.MOV -b 45M -s 1920x1080 -vcodec dnxhd -acodec libfaac
-ab 127K Video1.MOV
By the way:
During my analysis I noticed that the ffmpeg command is being substituted
by the avconv commad, it seems the arguments I used to ffmpeg are
compatible to avconv.
The important command arguments are "-acodec libfaac -ab 127K".
Without the "-ab 127K" the converting stopped after 1 sec and gave the
errors
"[libfaac @ 0x971fd60] libfaac doesn't support this output format!"
and
"Error while opening encoder for output stream #0.1 - maybe incorrect
parameters such as bit_rate, rate, width or height".
I chose the "127K" bit rate because I saw the same rate in the original
video file.
You can see the details of a video file by applying just the "-i <input
file>" to avconv,
like on the following lines:
avconv -i DSCN0798.MOV
avconv version 0.8.3-4:0.8.3-0ubuntu0.12.04.1+codecs1, Copyright (c)

At least one output file must be specified
In above line "Stream #0.1(eng): Audio: aac, 48000 Hz, stereo, s16, 127
kb/s"
you can see the bit rate of "127 kb/s".
I had played with some encoders I found capable of encoding audio like
"mp3" and "mp3ac" but, surprisingly, they were not known to ffmpeg/avconv
although the appear in the list of support codecs. You can see the codecs
in the output of "avconv -codecs".
Sound is working now in cinelerra and I will start editing my videos in the
next days.
Thanks very much to all who helped.

Betreff: Fwd: Re: [CinCV] CinCV 2.2: No sound in playback
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,

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.

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
