Problems playing RTP-streams (mjpeg, h264)

Hey,

I would like to play rtp-streams, mjpeg and h264 coded. I'm streaming from localhost using vlc. Receiving and playing with ffplay is working flawless. The error messages with mjpeg are:

"Decode video failed. undecoded: 2/2"
[FFmpeg:mjpeg] Found EOI before any SOF, ignoring
[FFmpeg:mjpeg] No JPEG data found in image
"[VideoDecoderFFmpegBase] Invalid data found when processing input"
...

The stream is playing anyway.

And with h264:

FFmpeg:sdp] RTP: missed 1080 packets
[FFmpeg:sdp] max delay reached. need to consume packet
[FFmpeg:sdp] RTP: missed 14 packets
[FFmpeg:sdp] max delay reached. need to consume packet
[FFmpeg:sdp] RTP: missed 3 packets

The stream is playing for one or two seconds, then these errors start to show up.

It may be a single or different issues, I don't know.

How to reproduce: VLC-Server: Media -> Stream -> add h.264-File -> Stream -> 3xnext -> paste the following strings into the textbox. for MJPEG (reencodes h264 to mjpeg): :sout=#transcode{vcodec=MJPG,vb=6000,acodec=none}:rtp{dst=127.0.0.1,port=5004} :sout-keep for h264 (just sends out): :sout=#transcode{acodec=none}:rtp{dst=127.0.0.1,port=5004} :sout-keep

on the player side I'm using the sdp-files as follows: mjpeg:

c=IN IP4 127.0.0.1
m=video 5004 RTP/AVP 26 
a=rtpmap:26 JPEG/90000

h264:

c=IN IP4 127.0.0.1
m=video 5004 RTP/AVP 96 
a=rtpmap:96 H264/90000

Code:

OpenGLWidgetRenderer* openGLrenderer = new OpenGLWidgetRenderer(this);
this->m_player = new AVPlayer(this);
this->m_vo = new VideoOutput(openGLrenderer->id(),this);
this->m_player->setRenderer(this->m_vo);
QVariantHash opt;
// probably since ffmpeg 3.x:
opt["protocol_whitelist"] = "file,udp,rtp";
this->m_player->setOptionsForFormat(opt);
this->setCentralWidget(this->m_vo->widget());
this->m_player->play("/home/devel/video_samples/test_mjpeg.sdp");

Playing the same file from disk is working fine with both QtAV and ffplay. I'm using QtAV edc59c87bcec46f03642becffa1026481edc5109 and ffmpeg 3.1.2 with Kubuntu 16.04.

Any ideas?
