Rico Tzschichholz, thank you very much, you are absolutely correct. There was OpenCV 3.3 installed on my system, it remained after update from 16.04 to 18.04 with all its 16.04 dependencies. I removed OpenCV 3.3 and everything got fixed. Thanks a lot for help. The issue is fixed and may be closed.

I use gstreamer and libopencv_videoio in my project. System is Ubuntu 18.04.5 The problem is that versions of libx264 get mixed due to implicit linking. Libraries are linked like this: gstreamer -> x264enc -> libx264-152 libopencv_videoio -> libavcodec-ffmpeg.so.56 -> libx264-148 Both opencv-based code and gstreamer-based code works well if used separately. At the top of backtrace I see: Thread 13 (Thread 0x7f28e2066700 (LWP 26012)): #0 0x00007f290181c853 in x264_add8x8_idct_avx2.skip_prologue () at /usr/lib/x86_64-linux-gnu/libx264.so.152 //!!!! 152 #1 0x00007f2927a93f55 in x264_nal_encode () at /usr/lib/x86_64-linux-gnu/libx264.so.148 //!!!! 148 #2 0x00007f2927af866c in () at /usr/lib/x86_64-linux-gnu/libx264.so.148 #3 0x00007f2927b0143b in x264_encoder_headers () at /usr/lib/x86_64-linux-gnu/libx264.so.148 If I use objdump I can find x264_add8x8_idct_avx2.skip_prologue in both libx264-148 and libx264-152 Here is example code which fails (C++ needed): int main (int argc, char *argv[]) { App *app = &s_app; GError *error = NULL; GstBus *bus; GstCaps *caps; gst_init (&argc, &argv); auto cap = cv::VideoCapture("videoplayback.mp4"); cv::Mat f; cap.read(f); cv::imshow("f", f); GST_DEBUG_CATEGORY_INIT (appsrc_pipeline_debug, "appsrc-pipeline", 0, "appsrc pipeline example"); app->loop = g_main_loop_new (NULL, TRUE); app->timer = g_timer_new(); app->pipeline = gst_parse_launch(R"(filesrc location=videoplayback.mp4 ! decodebin ! videoconvert ! x264enc byte-stream=true threads=1 tune=zerolatency bitrate=4000000 key- int-max=50 option-string="force-cfr=1" ! video/x-h264,profile=baseline,stream-format="byte-stream" ! h264parse ! mpegtsmux ! hlssink location="/tmp/data%06d.ts" max-files=100 playlist-length=10 playlist-location="/tmp/kek" target-duration=10 playlist-root=".")", NULL); g_assert (app->pipeline); bus = gst_pipeline_get_bus (GST_PIPELINE (app->pipeline)); g_assert(bus); gst_bus_add_watch (bus, (GstBusFunc) bus_message, app); caps = gst_caps_new_simple ("video/x-raw-rgb", "bpp",G_TYPE_INT,8, "depth",G_TYPE_INT,8, "width", G_TYPE_INT, 640, "height", G_TYPE_INT, 480, NULL); gst_element_set_state (app->pipeline, GST_STATE_PLAYING); g_main_loop_run (app->loop); GST_DEBUG ("stopping"); gst_element_set_state (app->pipeline, GST_STATE_NULL); gst_object_unref (bus); g_main_loop_unref (app->loop); return 0; } How can I solve this?
