RE : headers missing via rtpmp4vpay and rtpmp4vdepay

Hello Neel,

I guess your pipeline is something as follows
filesrc ! rtpmp4vpay ! rtpmp4depay ! filesink

Can you try the following pipeline
filesrc ! mpeg4videoparse ! rtpmp4vpay ! rtpmp4depay ! filesink
and see if you still face the problem ?

Regards,
Arnab

Hi.

I used the appsrc to write to a file via filesink, and the video was perfect but if I used the appsrc, rtpmp4vpay, rtpmp4vdepay, filesink to write to a file, then the MPEG4 headers were missing from the file. I used a hex editor to manually insert the headers and then the file was perfect. So, where is the problem? Is there a bug in the rtpmp4vpay/rtpmp4vdepay or am I doing something wrong with handling the buffers? I don't think that there is a problem in the handling of buffers on my side as the direct writing to a file worked perfectly.

Can someone help me out?? I am unable to transmit the video via UDP/RTSP and play it as the headers are missing and hence the VLC does not decode it (I have a problem with RTSP transmission via gst-rtsp-server too. I had posted it on the mailing list yesterday).

Thanks in advance.

Regards,
Neel.

Hello Folks,
                I am using rtpsend plugin for one of my application and I observed that there is a memory leak in the application. When I investigated the rtpsend plugin, I found that there is no dispose/finalize function implemented for the same. Is it not required? If it is required, then how do I implement it? Can it be the cause of memory leak?

Aniruddha

RE : headers missing via rtpmp4vpay and rtpmp4vdepay

Hi Arnab,

I checked out what you said, but it doesn’t work yet. The headers are still missing. After inserting the headers manually, using the hex editor, the file works successfully. The only difference noticed is that the VLC streams the file but give me warnings and does not display the video.

The actual pipelines are

appsrc is-live=true name=source caps=" video/mpeg, mpegversion=(int)4, framerate=(fraction)1001/30000, width=(int)1280, height=(int)720" ! mpeg4videoparse ! rtpmp4vpay pt=96 name=pay0 ! rtpmp4vdepay ! filesink location=/opt/rtp.m4v

appsrc is-live=true name=source caps=" video/mpeg, mpegversion=(int)4, framerate=(fraction)1001/30000, width=(int)1280, height=(int)720" ! filesink location=/opt/rtp.m4v

I am getting custom application buffers, hence I am using appsrc, to feed to the pipeline. My final aim is to transmit the data using gst-rtsp-server. So, I want to check out that this is a bug or not. If it is so, I would be unable to transmit the data using gst-rtsp-server.

Thanks for your help.

Regards,

Neel.

Hi,
did you solve the problem of rtpmp4vpay & rtpmp4vdepay?
I checked the problems that you explained . I'm using a DM 355 EVM board.

Any suggestions will be appreciated...

Thank for all.

Regards.

Lorenzo
