The VideoLAN Forums

First of all, dcreeron, thank you very much for your investigation! It really helped me but I would like to add some more information for those who will face this bug in future. I have noticed it is enough to disable Advanced Text Services then enabled it again and reboot. So you don't need to keep ...

I'm trying to record 352*288 MPEG4 stream from LAN-camera using VLC 1.0.3. But I have to use low bitrate (128kbit/s) and this causes problems. MP4V codec displays a lot of artifacts, h264 records well but desynchrones audio. h264 is fixed in VLC 1.1 but I can't use it at the moment. Are there any ot...

I already use audio-sync in my command line...

I'm trying to record LAN-camera video using the following command line: vlc "rtsp://10.101.220.40/mpeg4/media.amp" :sout=#transcode{fps=25,vcodec=h264,vb=128,acodec=mp3,ab=24,audio-sync}:duplicate{dst=display,dst=std{access=file,mux=mp4,dst="C:\1.avi"}} It works property in VLC 1...

I am recording low-bitrate video from LAN-camera and get file with 8-9 fps but my customers need 25. Is there any way to achieve higher fps (I think even faking will be okay).

I'm using libvlc at my C# application. It first records a stream from a camera and then tries to playback it. Recording is made okay but VLC crashes my application when I try to start playbacking. I tried to switch logging on but it didn't show anything. Is there any way to find out why VLC is crash...

libvlc_media_get_duration return -1. But if I play the file using VlcPlayer it's duration is shown okay. Is there any way to get file duration without playing it?

I'm recording RTSP stream using VLC and sometimes audio is lost. It is played for several seconds and then is becomes lost.

I really have no idea who's bug it is: RTSP source (LAN-camera) or VLC. Could it be VLC?

How can I reproduce "Keep original video" (during converting) behaviour using command line?

My application records video using several segments. So one player instance record the stream, than it is stopped and some time later a new player is created for recording. Sometimes my application is hanged. I think the reason is VLC deadlock. Are there any nuances to prevent VLC deadlock when seve...

I'm recording video from LAN-camera that streams mpeg4 file. I set "keep original video" at encoding settings but as result I get very heavy file. Does "keep original video" feature work anonther way comparing to what I expect?

I'm using libvlc 1.0.3 at my application and sometimes (really I can't figure out the reason) my application is handed. The only reason for that I can see is some deadlock in libvlc. Is this behaviour known? Are there any improvements in this way in 1.0.5?

When I pause ts files in VLC and change trackbar's position, trackbar is moved a bit by VLC (so it chooses other position). As I understand, it is ts-specific behaviour. How can I implement it using libvlc (now I have problems positioning ts-file).

I see a degraded picture for ts muxer at my libvlc based application: http://disk.tom.ru/k4krn87/1/9c2eb/Image.JPG
VLC doesn't have such an effect. Is there any special option for this?

VLC playbacks MPEG-TS files, but doesn't compute it's length. Is it unreal to get file length if position is computed well?

I have upgraded my application from using VlcMediaPlayer to VlcMediaListPlayer and I am very dissapointed how unstable it is. Firstly, VlcMediaListPlayer's Pause method works as Pause/Resume (so you need to track player's state at your application level). Secondly, sometimes (when one item was playe...

Ultraseamus, I use two events (don't remember their full names) for handling network problems:
1. Error: It is raised if vlc can't connect to the source at recording start
2. Ended: It is raised if there is no signal for more than rtp-timeout seconds

No timing... But can't we compute the length?

When I record using TS muxer, the video length and fps are equal to zero. Inspite of this problem VLC plays such video. But I can't play it using libvlc: for example, PositionChanged event is not raised.

It would be very convenient to get EndReaching (or something like that) event and cancel media unloading. When I get EndReached event, I can't prevent media unloading and continue working with this media. Are there any plans on supporting such a feature?

Please copy the content of VLC folder to your startup folder. If it help, it will localize the problem.

And what .NET binding/wrapper do you use?

I'm recording video from LAN-camera using VLC. But I need to be sure my file will be readable even if computer or VLC is crashed. Is it possible? What muxer should I use? If it is not possible, is there any way to restore a file that was not correctly finished because of crash?

Are there any news about this feature?

Helkaraxe, try to change your muxer to mp4. Muxer is set at InternalObjects folder (don't remember project and class).

What are the advantages/disadvantages of both players?
