Video stops part way in quicktime playback, audio continues

[dcam]

Hi,

VLC media player 0.8.6a and previous for windows, running on XP SP2 doesn't play back many of my Quicktime files successfully.

It starts playing them, but the video stops part way through, though the audio continues playing.

The same files play ok with the Apple Quicktime player.

Here's a sample file that you can use to reproduce the problem:

Any ideas?

The error I'm seeing occurs when the URL I mentioned is fully downloaded to a local file.

My email flipped around is: pastornet.net.au@david

It might help if you go to: Preferences > Video (check the "Advanced options" box at the bottom-right corner of the preferences menu) and check the box for "Drop late frames" and also, going down one more tad: Video > Output modules, change the output to "DirectX video output" and see if this improves anything.

Iif all of the files you have are JPEG formats in a MOV container, they are not supported by VLC. However MJPEG is supported.

"Drop late frames" was already checked.
Setting the output to "DirectX video output" didn't make any change in behaviour.

The file plays, it is just that when playing with VLC media player, the video playback stops part way through.

Under View/Stream and Media Info it says:

Stream 0:
Codec: jpg
Language:
Type: Video
Resolution 640x480
Display resolution: 640x480
Frame rate: 30.000000

Stream 1:
Codec: araw
Language:
Type: Audio
Channels: 1
Sample rate: 8000 Hz
Bits per sample: 8
Bitrate: 64kb/s

jpg = JPEG which is not supported. I'm not sure what part of unsupported you don't understand?

MJPEG is supported again in VLC 0.8.6 while it went through a brief period of problems in 0.8.5

Mplayer plays this file just fine.

Actually, some other software I have reports this below as the stream detail, which seems to indicate M-JPEG.

I have a similar problem to dcam with a mov file of NON-jpg formats. The media info says the codec is rpza. The video usually doesn't play at all, although a few times I thought I cought a glimpse it going super-fast all the way to the end (it's only 20secs so it's hard to catch). I download it to my HD too. See it at http://sealevel.jpl.nasa.gov/gallery/ti ... riolis.mov.

As above, "drop frames" was checked, and changing to DirectX didn't make a difference.

@dcam This may be why MPlayer plays the MOV and VLC doesn't:

using unscaled yuv420p -> bgr24 special converter

@sailor.nir Your URL doesn't work.

[sailor.nir]

You're right. Sorry about that. Here's another try:

Supported Formats

The container is supported the format is not.

I have a Panasonic-Lumix FX01 making videos with Quick Time Motion JPEG format.
With VLC V0.8.6b the video freezes after some seconds and the audio doesn't work.

I get a lot of information in the logfile like this:

ffmpeg warning: cannot decode one frame (35136 bytes)
ffmpeg warning: Subsampling in JPEG-LS is not supported.
(mjpeg@00B5C600)

With crtl-i I get codec:jpeg, but in manual of the Panasonic it is Motion JPEG.
In this forum I saw that mjpeg ist supported?

By the way, with VLC V0.8.4 the Video and audio works perfect.

thanks in advance

It could easily be a version problem with FFmpeg.

It appears this has been changed again for VLC 0.9.0

[feichth]

thanks for your quick reply.
Does this mean, that version 0.9.0 will soon be published?

No! But nightly builds are available for testing.

[feichth]

ok thanks, I tested the "vlc-0.9.0-svn-20070520-0138-win32.exe" and it works fine but the "vlc-0.9.0-svn-20070521-0000-win32.exe" which I have testet first, didn't run anyway.

I have almost exactly the same problem with 0.8.6c - .MOV files from a Panasonic Lumix camera; same errors in the log. The only difference for me is that the audio works fine, while the video freezes mid-way through (plays for many seconds, though).

I downloaded and installed 0.8.4a, and it works FINE.
