Add server options to send raw H.264 without using the client

[rom1v]

This is useful to use the scrcpy-server alone (without the client) just to get the raw H.264 stream:

adb push scrcpy-server /data/local/tmp/scrcpy-server.jar
adb forward tcp:1234 localabstract:scrcpy
adb shell CLASSPATH=/data/local/tmp/scrcpy-server.jar \
    app_process / com.genymobile.scrcpy.Server 1.22 \
    raw_video_stream=true tunnel_forward=true control=false

As soon as a client connects via TCP to localhost:1234, it will receive the raw H.264 stream.

For example, it can be played with VLC (but with a lot of delay due to buffering):

vlc --demux h264 tcp://localhost:1234

Can windows support this?

[rom1v]

Yes, it's platform-independent.

[elf-world]

But VLC didn't respond when I used it on windows.

[elf-world]

It cannot be played due to the firewall. It has been solved now. But how to set the frame rate and code rate of the original H.264 video stream?

[rom1v]

The H.264 has no fixed framerate: a new frame is produced whenever the device screen surface "changes".

To play it with VLC, see https://code.videolan.org/rom1v/vlc/-/merge_requests/20

@rom1v thank u for this, but I'm trying to get the server.jar file, I think I have to update the gradle file to build a jar file, I tried but I couldn't find the right way to do it? I'm new to gradle, do you have any idea how I can get the server.jar file by building the source code?

[rom1v]

adb push . \scrcpy-server /data/local/tmp/scrcpy-server

You put an extra space between . and \.

You can also add cleanup=false to avoid removing the server on the device.

Thanks, this is really a low mistake due to my oversight. That's why I deleted my reply. Thank you very much for your reply.

after running the last command on adb it returns "Aborted" after about 2 seconds
im running the command in 1 line:
adb shell CLASSPATH=/data/local/tmp/scrcpy-server.jar app_process com.genymobile.scrcpy.Server 1.22 raw_video_stream=true tunnel_forward=true control=false

my scrcpy-server is the one from the current scrcpy-win64-v2.1.zip
any idea whats the problem?

[rom1v]

Read https://github.com/Genymobile/scrcpy/blob/master/doc/develop.md#protocol

[JJLo1]

ah, ok i broke it by accidently deleting the forward slash between app_process and com.genymobile...
ty for quick answer though
Edit: your documentation says adb push scrcpy-server-v2.1 /data/local/tmp/scrcpy-server-manual.jar even thought i have not seen scrcpy-server file with appended version number yet (neither in downloaded variants nor after building myself)

@rom1v , I tried the commandlines , on my side i couldnt get the adb commandline to work, this gives me : aborted as a result (the phone is able to stream the camera otherwise.. the concept of scrcpy streaming directly some h264 is promising and opens a lot of possibilities of recycling old phones as cameras over tcpip (looking at you frigate and go2rtc), but for this to happen, we would need something easy to just enable the stream while the phone is starting. would it be easy to have a dead simple user interface on the apk/jar scrcpy-server sideloaded ? (unsure if the scrcpy is a jar file or an APK..).
