scream L4S run error about scream

[jacobt21]

Hi,

1. Did you

Modify scripts/ecn_env.sh

ECN_ENABLED=1
Make sure that MY_GST_INSTALL points to the correct install directory.

2 Please modify sender.sh
killall -9 scream_sender
+which gst-inspect-1.0
+gst-inspect-1.0 gstscream
+gst-inspect-1.0 x264enc
$SCREAM_TARGET_DIR/scream_sender --verbose
3. Run sender.sh.

[xiaoshuyu6]

I have executed the modified send.sh script as per your instructions. However, I still encounter an error. The operating system I am currently using is Ubuntu 20.04 with kernel version 5.15.0-88-generic. Do you recommend changing the operating system for testing purposes?

[jacobt21]

Hi, You are not using gstreamer that you’ve built and installed in your local directory: Plugin Details: Name x264 Description libx264-based H264 plugins Filename /lib/x86_64-linux-gnu/gstreamer-1.0/libgstx264.so Version 1.16.2 If you did, gst-inspect would point you to libgstx264.so that you’ve built. In command meson setup --prefix=/path/to/install/prefix What’s your /path/to/install/prefix? What’s your MY_GST_INSTALL ?

Hello, I might not have specified the installation path during setup, and it's possible that the default path was used. The command I executed was 'meson setup builddir'.

Currently, after running 'gst-inspect-1.0', the output on my system is as follows:

Do I need to reinstall? If so, what path should I specify for the installation?

[jacobt21]

Hi, I think there is meson command to set install dir. The install dir can be in any place , for example gstreamer/install. BTW, gst-inspect gstscream will always fail unless you set correct env vars. https://github.com/EricssonResearch/scream/blob/0b451ff3ff0f648a9607abcc013f47e06f5e2e64/gstscream/scripts/sender.sh#L8 Thanks * Jacob From: xiaoshuyu6 ***@***.***> Sent: Monday, November 27, 2023 12:02 AM To: EricssonResearch/scream ***@***.***> Cc: Jacob Teplitsky ***@***.***>; Comment ***@***.***> Subject: Re: [EricssonResearch/scream] scream L4S run error (Issue #58) Hello, I might not have specified the installation path during setup, and it's possible that the default path was used.

Hello, I've followed your instructions and successfully reinstalled the program. Now, MY_GST_INSTAL is set to $SCRIPT_DIR/... /... /... /gstreamer/install.

When I executed . /script/receiver.sh, it worked fine and produced the output: "screamrx/imp.rs ecn-enabled."

However, when I run . /script/sender.sh, it still throws an error. Here's the content of the output file for your reference.

I also used gst-inspect-1.0 x264enc and successfully located it as follows:

Hello, I've followed your instructions and added the sender.sh script, which includes the commands gst-inspect-1.0 x264enc and gst-inspect-1.0 avdec_h264.

Below is the output from the sender side.
send4.log

According to the results, avdec_h264 should be present, but x264enc is not.

[jacobt21]

Hi, Do you have file libgstx264.so in your build dir and install dir. If not check build/meson-logs/meson-log.txt to see if x264enc is disabled.

Thank you for your guidance. I've checked, and unfortunately, I couldn't find the libgstx264.so file in both the build directory and the install directory. Additionally, upon inspecting the meson-log.txt file in the build/meson-logs directory, it appears that x264enc is disabled.

Is there a specific step or configuration that I might have missed in enabling x264enc during the build process?

In addition, I would like to provide another piece of information. When I disable L4S by setting ECN_ENABLED=0 in ecn_env.sh and run sender.sh, the program output is normal, and I can detect x264enc.

I am wondering if the issue might be related to the version of GStreamer that I installed. I used the following repository: https://gitlab.freedesktop.org/samhurst/gstreamer/-/tree/ecn, specifically the ecn branch.

I did not use the command patch -p1 < <2717.patch. I'm unsure if this might be a problem.

It appears to me that the changes introduced by the patch and the code in the ecn branch are consistent. However, I'm not entirely certain if my understanding is accurate.

I performed the installation using the following commands:
meson setup --prefix=/path/to/install/prefix builddir
meson compile -C builddir
meson install -C builddir

Your insights or suggestions on any potential issues would be greatly appreciated.

[jacobt21]

Hi, Try meson setup --reconfigure -Dgst-plugins-ugly:x264=enabled -Dgpl=enabled <build_dir> --prefix=<your_install_dir> You might as well enable x265 and if your server has Nvidia GPU, nvcodec.
