Streaming RTSP-stream into file - no video data

[_eXile_]

Hi,

I try to stream a RTSP-stream into a file. However, when I play the created file, it has apparently no video data in it. As I am not that experienced with the vlc command line options, I tried to set the streaming options with the GUI:

I hit CTRL-N, checked the "RTSP" option and set the "URL" to "rtsp://c36000-o.m.core.cdn.streamfarm.net/36000zdf/ondemand/3546zdf/zdf/zdf/07/09/070905_toll_neu_f21_vh.mp4". Then I checked the "Stream/Save" option, an went into the "Settings..." dialoge.

In the settings-dialoge I checked "File" and set the "Filename" to "movie.mpeg". Under "Transcoding options" I checked "Video codec" and "Audio codec". All other settings were not changed. The resulting sout-MRL is:

Code: Select all

:sout=#transcode{vcodec=mp4v,vb=1024,scale=1,acodec=mpga,ab=192,channels=2}:duplicate{dst=std{access=file,mux=ts,dst="movie.mpeg"}}

I hit "OK" twice and waited 10 seconds until the streaming started and waited until the streaming ended. Then I opened the created movie.mpeg file normally and I can see no video output. There are no video tracks available.

The output while streaming is:

Code: Select all

I hope you can help me with getting the video data streamed into the file.

Hi,

Now I tried the command line and tried - according to the manual - these parameters:

Code: Select all

vlc -vvv rtsp://c36000-o.m.core.cdn.streamfarm.net/36000zdf/ondemand/3546zdf/zdf/zdf/07/09/070905_toll_neu_f21_vh.mp4 --sout file/ts:movie.mpeg

However, the file keeps being 0KB big, an vlc doesn't quit streaming! It simply stops one second before the end and doesn't close the stream. Can anyone else confirm this behavior with version 0.8.6c? Am I doing something wrong? The message log is still flooded with "main warning: trying to send non-dated packet to stream output!" ...

Edit:
After searching all day long, I've found a similar case at viewtopic.php?f=2&t=38877
I ask everybody who is ready is to test this with their vlc version, otherwise I will file a bug report

To test it simply run in your command line:

Code: Select all

vlc -vvv rtsp://c36000-o.m.core.cdn.streamfarm.net/36000zdf/ondemand/3546zdf/zdf/zdf/07/09/070905_toll_neu_f21_vh.mp4 --sout "#std{mux=ts,access=file,dst=movie.mpeg}"

An check the filesize of movie.mpeg.

eXile.

Hi,

OK problem resolved - VLC just doesn't support it at the moment. When trying to stream it into a file as raw data, I get the warning:

Code: Select all

access_realrtsp warning: only real/helix rtsp servers supported for now

Which means, that ... um ... at least some time this problem will be fixed

Regards,
eXile.

I'm trying to save a live stream streamed by VLC with the rtp module so every elementary stream uses a different port.

VLC displays it correctly for example with the code 'vlc http://<someip>:8080/file.sdp' but when I try to store that stream into a file I only get the audio.

After much looking around, trying to get SDP information with RTSP or HTTP protocol doesn't change anything.

Just changed the above code line to 'vlc http://<someip>:8080/file.sdp --sout="#display" and only the audio plays, no video at all and many messages line saying: "main stream output warning: trying to send non-dated packet to stream output!". So I suposed that the video packet lost the date in the transition between the RTP access module and the "stream out".

I'm going to try two other things:
* video only streaming by RTP.
* audio/video muxed in TS with only one UDP port.

Tried in Windows and streaming with multicast address.

[vice]

* Streaming only raw video with RTP by an SDP anounce, same results. It plays perfect without sending the output to the steam output module, but when I pass the stream to sout (with anyting like --sout="#display" or to a file), no video, (no audio of course, not present in this stream) and the same errors:
main stream output warning: trying to send non-dated packet to stream output!

* Streaming UDP or RTP with MPEG-TS mux to a broadcast address I get the following error:
packetizer_h264 warning: waiting for SPS/PPS (no idea what this could mean)
I only get the sound and no video so I haven't tried to stream it to a file or --sout "#display"


Next try: Try to change the codec to MPEG4 SP/ASP

[vice]

Finally the problem was the handle of VLC of the H264 codec. Streaming files encoded with MPEG-4@SP there's no problem and I can save to a file the streaming. Either RTP with differents ports or a MPEG-TS over UDP or RTP.

I think its a VLC bug because it plays normally when you DON'T activate any stream out option, the network stream was played by VLC perfectly. But, when you try to activate any stream out module (even with the display module alone with --sout="#display"), there's problems with the H264 video.

I'm going to do better tests, but aparenly event if I open this file (mp4 H264 encoded video) locally and try to stream out to a file, it doesn't save video. (Tested on a MacOS X VLC 0.8.6c).

Tried VLC version 0.8.6c in Windows. Haven't tested trunk version (future 0.9.0) so don't know if its a fixed problem.

[Martin Lindhe]

Hello all. I am experiencing the same problem, with stream input as H264 i can play back the video locally but when i try to stream this out with vlc, i get the error "main stream output warning: trying to send non-dated packet to stream output!". I tried both with VLC 0.8.6c and current VLC-svn, same problem.

Is anyone aware of a fix/workaround to this problem?

[Arateris]

I don't know if this problem has been taken in account by the development team, and since my posts in the other topic, I didn't find a solution to this problem.
This is not really the good place to ask this, but is there a way to capture the video display? (with any soft), because when we try to capture directly, it give only a black square instead of the video. I know this problem for long and why, but I didn't find a solution to it.

[vice]

I think, all is related to this:
https://trac.videolan.org/vlc/ticket/121

VLC have trouble making copies of H264 stream to process.

Just with --sout:#display you have errors.

[vice]

The above ticket is incorrect, but I don't remenber the good one.

Anyway, it's solved for the next release.

Tested with a windows build. Thanks j-b.

[vice]

The problem have been fixed for the next release!!!
Just wait a few days for the final binaries of the bugfix version 0.8.6e.

check:
http://trac.videolan.org/vlc/browser/tags/0.8.6e/NEWS

Code: Select all

Stream output: * Fixed waiting for SPS/PPS problem in H.264 packetizer

Thanks to all the developpers of VLC media player.

Now I have some sync problems with RTP streams of audio from a hardware encoder with RTP payload type 8, 10 and 11. I just ear a few initials seconds. I'll post more details in another thread.

[vice]

I'm not really sure if the H264 packetizer problem is solved.

Found a few diference between broadcast with VLC a H264 encoded file by RTP multicast and the same file served by VoD. (used TED Talks downladed files).

RTP multicast:

Code: Select all

new TEB broadcast enabled loop setup TEB input "C:\local\TED\ted_anderson_c_2002.mp4" setup TEB output #rtp{dst=224.1.1.1,sdp=sap,name=TEB}

With this latest version of VLC (the 0.8.6e) the image is shown but the video freezes for a few seconds regularly with PTS is out of range (this is the best case). Sometimes the VLC crashes trying to open the stream announced by SAP.

VoD:

Code: Select all

new TED vod enabled setup TED input "C:\local\TED\ted_anderson_c_2002.mp4"

A lot of messages "packetizer_h264 warning: waiting for SPS/PPS" and no image at all, only audio until I move the slider and the audio stops.
