Why VLC can not play the TS streams but ffplay can play?

[del77_111]

Hi,
I developped one video server which produce MPEG4 streams. But now I must change it to produce MPEG2 TS streams and use VLC to play it. Now I have several problems as:
1> VLC can not play TS streams(just only video stream) from my video server(there is one window spanned but no video displaying). But ffplay(the player of ffmpeg project) can play the same TS stream.
2> I plugin some code into VLC(before calling ffmpeg API to decode) to save the MPEG2 frames to one AVI file. VLC can play this AVI file.

Anybody can tell me how to fix the problem?
Thanks!

If you create the TS on your own: VLC depends heavily on a correcty [well - nearly makes it, too] PCR - no PCR, no play. For all the TS players I tested with my TS files VLC is the only one with this dependency (others are: Windows Media Player, MPC, Nero ShowTime and TSPlayer from DVBViewer). In addition some players (including VLC but VLC not being the only one) are sensitive on the internal time shifts between audio and video. I found that VLC works best if the video data (according to PTS) arrives around 2/3 seconds (on 25Hz data) before the audio: 1/2 second is defintly to small for high rate DVB data and 1 second is to much. Wrong shifts can lead to no sound (normal) or no picture (bit harder to generate). [ok, to be honest: I didn't fully found the solution. On A/V TS there is a 1:20 chance that the playback from file or UDP stream starts with no sound and on A only TS moving in the file the sound disappears - in both cases pause and play reactivates the sound]

Thank you very much!
<The enviroment:>
Video server generate video stream(no audio) and packetise to TS stream and multicasting them to network. VLC as client receive them and play.

<Current problem>
1> VLC can play TS stream from my video server. But there is one prolem as:VLC continue playing TS about 10 seconds and then stop playing about 4~5 seconds,and this happen periodly. In addition, while stopping playing the following message would be shown in message window of VLC:
"late picture skipped(2235468714)"
.......
"late picture skipped(2133564625)"
"more than 5 seconds of late video->drop frame(computer too slow?)"

2> So I think the value of PTS or DTS of my TS stream is wrong. But I don't know how to caculate correct PTS and DTS?

Please help me!

Well - actually I'm working with DVB streams which have PTS and DTS so I'm not much of a help. And generating the PCR from it is neither a problem, so...

Sorry

It seems obvious you have been working on this for a while and are a bit frustrated. But I feel like I'm walking into the middle of a conversation without having all the facts. Then another user kindly tries to help with some with some technical aspects of the container that may or may not be an issue here.

If I understand this correctly, you are trying to provide a stream using MPEG-TS for the encapsulation method (container) and having problem creating the source files that will play locally using VLC? I assume this is without streaming.

In your last post you seemed to indicate progress in this area, in that you kinda, sorta have it working but it doesn't work well.

1. What is the source? Please provide format for Audio, Video and container type.

I realize you said that you were working with MPEG4 streams and must convert. But this is to broad an area to make any comment. So please be specific.

2. What is the format for Audio and video to be used with the MPEG-TS container you want to stream.

3. Regarding your last post, What is the speed of your up connection to the Internet.

4. Have you looked at Stream and Media Information, Statistics for the server and the client?

[del77_111]

1. The format of video is MPEG2. The container type is MPEG-TS.
My video server can generate MPEG2 stream directly, so we need not convert MPEG4 to MPEG2. I close audio stream because we do not need it. After generate MPEG2 video, my video server encapsulate it with MPEG-TS and RTP then stream it to LAN(the bandwidth is 10~100M bps) with multicast UDP(such as 224.112.1.44:5043).We use VLC as client to receive multicast packets,decode and render them.

2.Now VLC can play the MPEG-TS stream cantabile for a long time after I improved the calulation of PCR on my video server. But sometimes the same problem as my previous post still was existed.

Try creating a sample file in the MPEG-PS container. When you setup to stream use the transcode options to put it in the MPEG-TS container. No video or audio transcode selections are necessary. Basically this is the default for encapsulation.

You could also try Preferences, (turn on the advanced option) then Advanced check the box marked "Increase priority of the process" or "Minimize number of threads". Try one at a time on the server, specially if there many things running in the background.

I read your last post again after my post and realized you are not using VLC on the server side, only on the client side.

You Messages file still seems to indicate a timing issue. I was trying to correct this by letting VLC do the timing for the TS container. This still may be a reasonable test (using VLC for the server) to help sort out the problem areas.

I noticed this one "ffmpeg error: more than 5 seconds of late video -> dropping frame (computer too slow ?)" preceded by a long string of late pictures. This seems to indicate large breaks in the stream. Could this be LAN traffic or a router problem? I'm assuming the the clients are not to slow.

Have you tried to use VLC to play the files locally and compare the massages files?

I don't know what to make of this one "packetizer_mpeg4video warning: waiting for VOL" specially when we are discussing MPEG-2 in a TS container as the stream source. I would think it would be packetizer_mpegvideo, but I may be mistaken on this.

There are a couple of options you could try on the client side. In Preferences, Access modules, UDP/RTP try increasing the cache size. You will never make 5 seconds though. Also in Preferences, Video try unchecking the box marked "Drop late frames" Then press Save and close the player.

Hope this helps!
