DVI IMA audio

When I play video's shot by the Casio EX-V7 the H.264 codec of VLC is doing an awesome job. But the sound is completelly messed up.
It is like stuttering all the time. Like 50% of a second it is well, the other 50% of a second it is all messed up. I use VLC 0.8.6c.

Hope support for DVI IMA audio will be added.
Because other players I use do not play H.264 as well as VLC.

Upload it in ftp://streams.videolan.org/incoming/ with a small txt file description (use the same filename except for the ext)

I agree with you, but of course there will be someone to argue as always! But I hope we will win!

Hello,
I'm facing exactly the same problem with my Casio-Videos (H.264); using Win-XP SPII, NVidea Audio V4.62, Athlon XP 2600+ . The Quicktime-Player works well, but the Processor-Usage is at the edge=100%. So I'm trying the VLC-Player, but there the sound is horrible stuttering :cry:

Luckily my Videos (made with Casio V8) in the YouTube-Mode are played without :lol: Audio-Problems!
The only difference is, that the YouTube-Sound is made with:
adpcm debug: format: samplerate:22050 Hz channels:2 bits/sample:16 blockalign:1024 samplesperblock:1016
The normal-Videos (as made with Casio V7 and/or V8) have following Samplerate:
adpcm debug: format: samplerate:44100 Hz channels:2 bits/sample:16 blockalign:1024 samplesperblock:1016

The rest of the trace is similar to both Videos (except the samplerate).

I already disabled direct-sound (as mentioned in viewtopic.php?f=2&t=8863&start=30&st=0& ... s+horrible
but the stuttering sound remains.

This error also occurs on an intel based PC, so MS-Windows or hardware dependend Sound-Driver are not guilty.
So I assume, this is really a bug within VLC! (The newest nightly build does not fix it)

Hi,

I just purchased the Casio EX-V8 digital camera and am also having the same problem as these other users. I get the same stuttering sound when playing the camera's h.264 quicktime(.mov) ultra high quality(UHQ) videos. I tested this on 3 different Windows XP SP2 computers using the latest (0.8.6e) VLC release and all show the problem. I think someone already uploaded a sample video, but one is available here:

I am going to make a $50 donation now hoping it will help encourage a developer to take a look at this issue :D
Let me know if I can provide any other information or sample files to help with resolving this.
Thanks.

Hi All,
I'm creating an application in c# which is using vlc interface in c# for getting the live streams.
Some times or other there is a application crash which says that there is some error(microsoft error window comes up) due to libffmpeg_plugin.dll file or due to ntdll.dll file and the application closes.

I just need help regarding this.
