mjpeg video streaming issue..

[Ravi-Teja-konda]

Hello everyone,

I am using openAVnu-master repo and i built the repo with the below flags:

AVB_FEATURE_ENDPOINT ?= 1 -- (SRP Enabled) IGB_LAUNCHTIME_ENABLED ?= 0 AVB_FEATURE_GSTREAMER ?= 1 -- (Gstreamer Enabled) PLATFORM_TOOLCHAIN ?= generic -- (Generic Platform)

I've tested mpeg2ts video streaming with SRP and MAAP enabled .it worked fine but with 2 seconds delay. But when i Started running mjpeg and also h264 video streaming talker is opening the camera and sending the data but on listener side it is not receiving the AVTP packets. i tested pipelining gstreamer data to a file just to check the size of file if it receives any packets but it has not worked..

Below is the log of mpeg_listener..

Any comments would be a grate help.

Thank you, Ravi Teja.

Hi Ravi, Change the interface name in endpoint.ini to the one that you are using.

Hello JXter,

Thank you for the reply, I've tried setting interface name in endpoint.ini but no result.

Are you still getting this error, ERROR: Error in INI file: endpoint.ini, line 4 Setting the value in endpoint.ini in bin directory will solve this error temporary; or if you want a permanent solution, change it in endpoint.ini in endpoint directory and compile the pipeline again.

Hello JXter,

ERROR: Error in INI file: endpoint.ini, line 4 got resolved , but the video displaying issue for mjpeg is not yet resolved..

[JXter]

Can you share the new logs. I don't see any other error in the shared logs.

[Ravi-Teja-konda]

Hello JXter,

Thank you for the quick response. The log shows no error but I'm missing the packets which are sent from the talker. it is like [INFO: RX a0:36:9f:25:36:40/1, Totals: calls=70, frames=0, lost=18446744073709551615, bytes=0 ] listener detects the domain class and attaches to the talker stream and runs the gstreamer pipeline with no error but it is unable to get the AVTP Packets from the talker ..

I've checked talker by pcap it is sending the AVTP packets..
