  • ffmpeg transcoding stop after few seconds

    9 avril 2018, par Salem F

    Hi i’m trying to do this over week now with no success ,
    What’s i’m trying to do is transcoding video from live streaming source and downscale it with FFmpeg , but every time I start transcoding it broadcasting fro 11 Sec and stop . here last command I tried

     ffmpeg  -re  -i 'http://source.com/1034.ts' -preset ultrafast http://localhost:2052/feed1.ffm

    I tried to download the .ts file with IDM and it finish downloading the file on the exact 12 Sec that FFmpeg stop trans coding on it .

    does that means that FFmpeg download that file as one segment and not continued reading the source video As what video players does usually . BTW I tried with source with VLC player and it didn’t stop playing the the same source video .

    Edit :- I decide to pass FFmpeg command via FFserver config file ffserver.conf

    Launch ffmpeg -i 'http://source.com/1.ts' -copyinkf -codec copy  

    The stream works fine for a while but after testing couple sources I notice it’s struggle to trans-coding HD videos .

    I guess the issue with my VPS KVM server being very limited CPU and RAM ( 128MB only ) ! Since I tried using ultrafast preset but din’t solve the issue , another thing , I notice when I enable AVOptionVideo crf setting on ffserver.conf trans-coding runs bit smoothly without frame-rate dropping .
    Las my server uses Xeon L5520 CPU which is outdated CPU specially I gout 1/4 power of V single core (if they count HT it will be 1/8 of the real core ) :(

  • Jquery auto-refresh stop refreshing after 10seconds

    11 février 2016, par Mick Jack

    I have this JQuery script to auto refresh every 2seconds after a video is uploaded and retrieve the estimated time needed to process the video with ffmpeg

    However my refresh script stop refreshing after 10-15seconds. i traced the problem to the session_start() ; when i remove this session_start() ; my refresh script work perfectly. what could be the cause and solution here ?

  • How to start and stop saving video frames according to a trigger with OpenCV VideoWriter

    11 août 2021, par Jacob nighFor

    I am building an app that records frames from IP camera through RTSP.

    &#xA;&#xA;

    My engine is in charge to save a video in mp4 with Opencv VideoWriter working well.&#xA;What I am looking for is to create a startRecord and a stopRecord class method that will respectively start and stop recording according to a trigger (it could be an argument that I pass to the thread).&#xA;Is anyone know what the best way to do that kind of stuff ?

    &#xA;&#xA;

    Here is my class :

    &#xA;&#xA;

    from threading import Thread&#xA;import cv2&#xA;import time&#xA;import multiprocessing&#xA;import threading&#xA;class RTSPVideoWriterObject(object):&#xA;    def __init__(self, src=0):&#xA;        # Create a VideoCapture object&#xA;        self.capture = cv2.VideoCapture(src)&#xA;&#xA;        # Start the thread to read frames from the video stream&#xA;        self.thread = Thread(target=self.update, args=())&#xA;        self.thread.daemon = True&#xA;        self.thread.start()&#xA;&#xA;    def update(self):&#xA;        # Read the next frame from the stream in a different thread&#xA;        while True:&#xA;            if self.capture.isOpened():&#xA;                (self.status, self.frame) = self.capture.read()&#xA;&#xA;    def endRecord(self):&#xA;        self.capture.release()&#xA;        self.output_video.release()&#xA;        exit(1)&#xA;&#xA;    def startRecord(self,endRec):&#xA;&#xA;        self.frame_width = int(self.capture.get(3))&#xA;        self.frame_height = int(self.capture.get(4))&#xA;        self.codec = cv2.VideoWriter_fourcc(*&#x27;mp4v&#x27;)&#xA;        self.output_video = cv2.VideoWriter(&#x27;fileOutput.mp4&#x27;, self.codec, 30, (self.frame_width, self.frame_height))&#xA;        while True:          &#xA;            try:&#xA;                self.output_video.write(self.frame)&#xA;                if endRec:&#xA;                    self.endRecord()&#xA;            except AttributeError:&#xA;                pass&#xA;&#xA;&#xA;&#xA;&#xA;if __name__ == &#x27;__main__&#x27;:&#xA;&#xA;    rtsp_stream_link = &#x27;rtsp://foo:192.5545....&#x27;&#xA;    video_stream_widget = RTSPVideoWriterObject(rtsp_stream_link)&#xA;&#xA;    stop_threads = False&#xA;    t1 = threading.Thread(target = video_stream_widget.startRecord, args =[stop_threads]) &#xA;    t1.start() &#xA;    time.sleep(15)&#xA;    stop_threads = True&#xA;&#xA;

    &#xA;&#xA;

    As you can see in the main I reading frames and store them in a separate thread. Then I am starting to record (record method is with an infinite loop so blocking) and then after 15 sec, I am trying to pass a 'stop_record' argument to stop recording properly.

    &#xA;&#xA;

    A part of the code comes from Storing RTSP stream as video file with OpenCV VideoWriter

    &#xA;&#xA;

    Is someone have an idea ?&#xA;I read a lot that OpenCV can be very tricky for multithreading

    &#xA;&#xA;

    N.
