gstreamer play video in android #4

Closed Larryyuan2015 closed 6 months ago

Larryyuan2015 commented 6 months ago

Hi fengjiongmax，

I put test.mp4 in the android equipment. It was ok to play the video by other gstreamer appwith the same pipeline on same android equiment. and I modified the native_binding.c file like below in this flutter project. but there was no image to come out. Could you help to check the issue? Thank you very much!

//m FFI_PLUGIN_EXPORT void setup_pipeline(void) { // Setup pipeline gchar *pipeline_description = g_strdup("filesrc location=/sdcard/test.mp4 ! qtdemux ! h264parse ! avdec_h264 ! autovideosink"); data->pipeline = gst_parse_launch(pipeline_description, NULL); g_free(pipeline_description);

if (!data->pipeline) {
    g_printerr("Pipeline could not be created.\n");
    return;
}

// Set pipeline state
gst_element_set_state(data->pipeline, GST_STATE_READY);

// Get overlay interface
data->overlay = gst_bin_get_by_interface(GST_BIN(data->pipeline), GST_TYPE_VIDEO_OVERLAY);

}

I'm not sure, did you add permission to access files to the android app? https://stackoverflow.com/questions/1992953/file-operations-in-android-ndk And please put logs in following format:

MatteoGigerSR commented 6 months ago

You are using new elements in your pipeline like avdec_h264 which belongs to the libav plugin. Did you include this new plugin? If not you will not get an image but it will compile and run with no error.

I included the plugin "libav" in CMAKE and added it to gst_plugin_init_android but then you get a bunch of unreferenced symbol errors to av functions:

 ld: error: undefined symbol: av_malloc
[        ]   >>> referenced by gstavutils.c:454

[        ]   >>> referenced 7 more times
[        ]   ld: error: undefined symbol: av_codec_iterate

and linking the library gstlibav doesn't help either

MatteoGigerSR commented 6 months ago

I managed to get raw video streaming over udp working but this is not very ideal... Unfortunately decodebin produces no output for me. Do you have any experience with decoding on android @fengjiongmax ?

fengjiongmax commented 6 months ago

@MatteoGigerSR I have some experience on audio, but I have not tried video before, can you create a sample repo so I can check on that?

MatteoGigerSR commented 6 months ago

Thanks, that would be amazing. I can create a repo tomorrow but if you manage to get the gstreamer plugin libav working that would already be amazing. Libav provides software decoding you will have to link the libraries avformat avcodec avutil but at this point I run in to a compile time relocation error (can't provide output right now but I will do so once I can). The 2nd option is hardware decoding. There is a gstreamer plugin called androidmedia but I can't find any documentation on it (only info: https://stackoverflow.com/questions/74607854/androidmedia-plugin-pad-templates) I also tried decodebin element which should select optimal decoding for you but there I get no video whatsoever.

Larryyuan2015 commented 6 months ago

@fengjiongmax I tried the below permissions in AndroidManifest.xml, There is still the same issue. As @MatteoGigerSR said, it can compile and run with no error but there is no image, I don't know how to output the log as you want. I just use adb logcat to catch the app related log as the information on https://github.com/fengjiongmax/fltgst/issues/4#issuecomment-2014739223

@MatteoGigerSR

Could you share the sample about playing raw video streaming over udp？Many thanks！

I managed to get raw video streaming over udp working but this is not very ideal... Unfortunately decodebin produces no output for me. Do you have any experience with decoding on android @fengjiongmax ?

MatteoGigerSR commented 6 months ago

use this as your pipeline in the app instead (make sure you include all plugins necessary for the elements otherwise you will see no error and no video)

data->pipeline = gst_parse_launch(
        "udpsrc port=5000 caps=application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264 ! rtph264depay ! decodebin ! videoconvert ! autovideosink",
        NULL);

for sending you can use: gst-launch-1.0 videotestsrc ! rtpvrawpay ! udpsink host="insert_correct_ip_here" port=5000

fengjiongmax commented 6 months ago

Now I remember, in the Android emulator, when listening to a port, it will only listen to localhost or 127.0.0.1, so if the IP you use is your LAN IP, the stream may not reach your Android emulator.

I have a solution for this for an app I built, which combines http://www.brokestream.com/udp_redirect.html, and a shell script, and I have pushed it to the repo: https://github.com/fengjiongmax/fltgst-portforward

You can check the read me for how to use it.

Larryyuan2015 commented 6 months ago

@MatteoGigerSR Could you help to provide the CMakelist.txt with all related plugins list? Thank you very much!

I'm assuming your saying that to @Larryyuan2015 's issue. I'm not using Android Emulator I'm using my real phone. I don't think my issue is related to networking as streaming raw video works fine.

@Larryyuan2015 Here's my plugin list make sure to register and declare them as shown in @fengjiongmax 's video LIST(APPEND GST_PLUGINS coreelements coretracers adder app audioconvert audiorate audiotestsrc videotestsrc videorate videofilter videoconvertscale videoparsersbad udp gio autodetect opensles ipcpipeline opengl playback rtp rawparse androidmedia)

also link the required libs here's my list LIST(APPEND LINK_LIBS intl ffi iconv gmodule-2.0 pcre2-8 gstbase-1.0 gstaudio-1.0 gstvideo-1.0 gstgl-1.0 gstcontroller-1.0 gstpbutils-1.0 gsttag-1.0 gstrtp-1.0 gstnet-1.0 png16 graphene-1.0 jpeg orc-0.4 gstapp-1.0 gio-2.0 android log z OpenSLES EGL GLESv2 gstcodecparsers-1.0 gstphotography-1.0)

fengjiongmax commented 6 months ago

@MatteoGigerSR I got the app compiles but did not try if it the pipeline works. replace your 

  LIST(APPEND LINK_LIBS intl ffi iconv gmodule-2.0 pcre2-8 gstbase-1.0 gstaudio-1.0 gstvideo-1.0 gstgl-1.0 gstcontroller-1.0 png16 graphene-1.0 jpeg orc-0.4 gstapp-1.0 gio-2.0 android log z OpenSLES EGL GLESv2 avutil avcodec avformat)

with 

  LIST(APPEND LINK_LIBS intl ffi iconv gmodule-2.0 pcre2-8 gstbase-1.0 gstaudio-1.0 gstvideo-1.0 gstgl-1.0 gstcontroller-1.0 png16 graphene-1.0 jpeg orc-0.4 gstapp-1.0 gio-2.0 android log z OpenSLES EGL GLESv2 avutil avcodec avformat gstpbutils-1.0 avfilter swresample bz2 gsttag-1.0)

  SET(CMAKE_C_FLAGS " -Wl,-Bsymbolic ")

Hope it works!

MatteoGigerSR commented 6 months ago

Thanks a lot for looking into this! Can you run the app? I can compile now as well but now it crashes on start for me.

fengjiongmax commented 6 months ago

Sorry, I didn't check beforehand, replace with this instead:


  LIST(APPEND LINK_LIBS intl ffi iconv gmodule-2.0 pcre2-8 gstbase-1.0 gstaudio-1.0 gstvideo-1.0 gstgl-1.0 gstcontroller-1.0 png16 graphene-1.0 jpeg orc-0.4 gstapp-1.0 gio-2.0 android log z OpenSLES EGL GLESv2 avutil avcodec avformat gstpbutils-1.0 avfilter swresample bz2 gsttag-1.0)

MatteoGigerSR commented 6 months ago

Amazing thanks! I now have software decoding working.

@fengjiongmax @MatteoGigerSR It is OK for build apk. Thanks for your help. I used your CMakeLists.txt with the following GST_PLUGINS. LIST(APPEND GST_PLUGINS coreelements coretracers adder app audioconvert audiorate audiotestsrc videotestsrc videorate videofilter videoconvertscale videoparsersbad udp gio autodetect opensles ipcpipeline opengl playback rtp rawparse androidmedia libav)

but there is no image to test below two pipelines. 1. filesrc location=/sdcard/test.mp4 ! qtdemux ! h264parse ! avdec_h264 ! autovideosink 2. udpsrc port=5000 caps='application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264' ! rtph264depay ! decodebin ! videoconvert ! autovideosink

there is a same error from log of device. Do you have any experience with this?

fengjiongmax commented 6 months ago

How do you create the pipeline and the elements? I suggest you use gst_element_factory_make to create the elements individually, and then do a null check so that elements are created. If you did use gst_element_factory_make to create elements, then please create an example repository so that I can check on that. @Larryyuan2015

Larryyuan2015 commented 6 months ago

Hi fengjiongmax，

I used the following method to create the pipeline.

FFI_PLUGIN_EXPORT void setup_pipeline(void) { // Setup pipeline gchar pipeline_description = g_strdup("filesrc location=/sdcard/test.mp4 ! qtdemux ! h264parse ! avdec_h264 ! autovideosink"); //gchar pipeline_description = g_strdup("udpsrc port=5000 caps='application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264' ! rtph264depay ! decodebin ! videoconvert ! autovideosink");

data->pipeline = gst_parse_launch(pipeline_description, NULL);
g_free(pipeline_description);

if (!data->pipeline) {
    g_printerr("Pipeline could not be created.\n");
    return;
}

// Set pipeline state
gst_element_set_state(data->pipeline, GST_STATE_READY);

// Get overlay interface
data->overlay = gst_bin_get_by_interface(GST_BIN(data->pipeline), GST_TYPE_VIDEO_OVERLAY);

}

then I changed the method like the below as your suggestion.

FFI_PLUGIN_EXPORT void setup_pipeline(void) { // Setup pipeline GstElement filesrc, qtdemux, h264parse, avdec_h264, *autovideosink;

filesrc = gst_element_factory_make("filesrc", NULL);
qtdemux = gst_element_factory_make("qtdemux", NULL);
h264parse = gst_element_factory_make("h264parse", NULL);
avdec_h264 = gst_element_factory_make("avdec_h264", NULL);
autovideosink = gst_element_factory_make("autovideosink", NULL);

// Check if elements are created successfully
if (!filesrc || !qtdemux || !h264parse || !avdec_h264 || !autovideosink) {
    g_printerr("Failed to create elements. Exiting.\n");
    // Clean up
    if (filesrc) gst_object_unref(filesrc);
    if (qtdemux) gst_object_unref(qtdemux);
    if (h264parse) gst_object_unref(h264parse);
    if (avdec_h264) gst_object_unref(avdec_h264);
    if (autovideosink) gst_object_unref(autovideosink);
    return;
}

// Set the location for filesrc
g_object_set(G_OBJECT(filesrc), "location", "/sdcard/test.mp4", NULL);

// Create the pipeline
data->pipeline = gst_pipeline_new("test-pipeline");
if (!data->pipeline) {
    g_printerr("Pipeline could not be created.\n");
    return;
}

// Add elements to the pipeline
gst_bin_add_many(GST_BIN(data->pipeline), filesrc, qtdemux, h264parse, avdec_h264, autovideosink, NULL);

// Link the elements
if (!gst_element_link_many(filesrc, qtdemux, h264parse, avdec_h264, autovideosink, NULL)) {
    g_printerr("Failed to link elements. Exiting.\n");
    gst_object_unref(data->pipeline);
    return;
}

// Set pipeline state
gst_element_set_state(data->pipeline, GST_STATE_READY);

// Get overlay interface
data->overlay = gst_bin_get_by_interface(GST_BIN(data->pipeline), GST_TYPE_VIDEO_OVERLAY);

}

fengjiongmax commented 6 months ago

Great, were the elements created successfully? or you can open the Android folder in fltgst and put a breakpoint at the null check line and see if all those elements are created.

Larryyuan2015 commented 6 months ago

@fengjiongmax As your suggestion，I set a breakpoint and debug the code with android Emulator Pixel 4a API 31，and these variables output the information as below. there is NULL for qtdemux element and it fails to create the pipeline . 

filesrc = gst_element_factory_make("filesrc", NULL);
qtdemux = gst_element_factory_make("qtdemux", NULL);
h264parse = gst_element_factory_make("h264parse", NULL);
avdec_h264 = gst_element_factory_make("avdec_h264", NULL);
autovideosink = gst_element_factory_make("autovideosink", NULL);

filesrc: 0x7a2ed0812420 qtdemux: 0x0(NULL) h264parse: 0x7a2e807e30f0 avdec_h264: 0x7a2e308b4f80 autovideosink: 0x7a2ea0824040

Then I added the plugin isomp4 again like this.

Then you need to add gstriff-1.0 to LINK_LIBS, then the app should build.

@fengjiongmax Thanks very much . After add gstriff-1.0, it works and it can play the video. Thanks again for your kindly help.
