memory leak on the lastest version.
Hi, i am using your project to decoder video stream from drones. I found that there is a memory leak when decoding the data. Here is the code:
import socket
import h264decoder
from scanner import Scanner
import queue
from memory_profiler import profile
@profile
def _h264_decode(packet_data, decoder, queue):
frames = decoder.decode(packet_data)
for frame_data in frames:
(frame, w, h, ls) = frame_data
if frame is not None:
frame = np.fromstring(frame, dtype=np.ubyte, count=len(frame), sep='')
frame = (frame.reshape((h, ls // 3, 3)))
frame = frame[:, :w, :]
while queue.qsize() > 1:
queue.get()
queue.put(frame)
def _receive_video_thread(video_socket, decoder, queue):
pack_data = ''
print("receive video thread start....")
while True:
try:
res_string, ip = video_socket.recvfrom(2048)
pack_data += res_string.hex()
if len(res_string) != 1460:
tmp = bytes.fromhex(pack_data)
_h264_decode(tmp, decoder , queue)
pack_data = ''
except socket.error as exc:
print("Caught exception socket.error(video_thread): %s" % exc)
scanner = Scanner('192.168.1.')
scanner.find_available_tello(1)
tello_list = scanner.get_tello_info()
print(tello_list)
video_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
video_socket.setsockopt(socket.SOL_SOCKET, socket.SO_RCVBUF, 10 * 1024)
video_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
video_socket.bind(('', tello_list[0][2]))
soc = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
soc.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
soc.bind(('', tello_list[0][1]))
soc.sendto('streamon'.encode('utf-8'), (tello_list[0][0], 8889))
queue = queue.Queue()
decoder = h264decoder.H264Decoder()
_receive_video_thread(video_socket, decoder, queue)
The memory monitoring result is:
get image.

the function decode() is the cause of the memory leak. I have tried to fix it by myself, but i am not familiar with C++ and libav. Could you please tell me how to solve this problem?
Is there anyone have the example file for testing the setup?
Is there anyone who has the example file mentioned in the example code?
I just want this file to run the demo code to make sure that my setup is correct.

Thank you all,
support h264decoder for python3 and macOS
hi together,
I love your decoder since this one really works with python2 and devices like the Tello drone.
Unluckily, python2 is not supported anymore :(
your decoder is really awesome, I would love to get a current version for python3
Could some one help me. How to solve Oak-D pro camera data decoding and display

How to fix it?
how to build this lib on python3 on ubuntu?
I have follow the guide, use setup.py to build this library, and get errors" by not providing "Findpybind11.cmake" , but I have installed pybind11 in the machine..
Could you please provide the details steps of setuptools to install this library?
Install in windows
env: visual studio 2017+win10
I have successfully installed ffmpeg with vspkg
But there are some problems when installing 264decoder，it seems like vcpkg can't find pybind11.

Support for hardware accelerated video decoding
Hi, does h264decoder support hardware acceleration (opencl, cuda, vaapi). If not, is it planned to implement this feature in the future?
ImportError: No module named libh264decoder
Hi I am trying to get this code to work in conjuction with a tello drone. But when i install all your packages it says theres a problem importing the libh264decoder. Is there a way you could help me get this working?
libavcodec.so.57: Cannot open shared object file
Hi all,
I was trying out both Tello_Video & Tello_Video_With_Pose_Recognition packages in my Linux - ubuntu 16.04 LTS
At first, I installed Tello_Video with the one click install and it has successfully run, however, when i tries to install and run Tello_VIdeo_With_Pose_Recognition, it shows the following errors, and now it no longer runs again.
I have checked and I moved the 'libh264decoder.so' file into my python's site-packages file & /usr/lib/ , the above move was suggested by the internet. But still getting the error:
spark@spark:~/Downloads/Tello-Python-master/Tello_Video_With_Pose_Recognition$ python main.py

Any help will be greatly appreciated.

I'm quite confused because It seems to be a incompatible question on ffmpeg, which AV_CODEC_CAP_TRUNCATED has been removed on ffmpeg 6.0, but I'm using ffmpeg 3.4.9 and I don't know how to fix that.
