ffmpeg - how to add duration to mjpeg or how to make mjpeg faster -

-

I have an IP-Cam MJPEG that I have created and it has a total of 240 frames

encoded sauce ffmpeg.exe -framerate 25 -ic: \% 06d.jpg \ -s 1920x1080 -qscale 1 -vcodec mjpeg -r 25c: \ result.mjpg -y

now I want to make my life the result by mjpeg player. Mjpg 

  My problem 1. I can not find the time of play time or duration of mjpeg 2. The game is slow then there is another movie player so I want to sync it play it faster   
 Ffprobe results  
  input # 0, mjpeg, 'result.mjpg' below: Duration: N / A, bitrate: N / A stream # 0: 0: Video: mjpeg, yuvj444p (PC, bt470bg), 1920x1080, 25 TBR, 1200K TBN, 25 TBC   
 results below -show_frame  
 < Code> [frame] media_type = video key_frame = 1 pkt_pts = 720000 pkt_pts_time = 0.600000 pkt_dts = 720000 pkt_dts_time = 0.600000 Srwottm_ifort_taimstmp = 720000 Srwottm_afort_timstmp_taim = 0.600000 pkt_duration = 48000 pkt_duration_time = 0.040000 pkt_pos = 4731406 pkt_size = 313,289 width = 1920 height = 1080 pix_fmt = yuvj444p sample_aspect_ratio = 333: 320 pict_type = I coded_picture_number = 0 Show_picture_number = 0 interlaced_frame = 0 top_field_first = 0 repeat_pict = 0 [/ frame]   
 ffprobe show I have period there: n / a, bitrate: n / a  
 How do I determine the duration and bitrate is there any encode-option I Have to set up?  
 When I interpret the mjpeg as below  
 I can not find the duration of 0 only  
  AVFormatContext * pfc; Int rate; PFC = avformat_alloc_context (); Ret = avformat_open_input (& amp; PFC, filename, zero, zero); If (rate end lie; 0) {// failed} Ret = avformat_find_stream_info (PFC, Nouvel); If (rate at lieutenant; 0) {// fail} printf ("duration% ld", pFC-> duration); & Lt; ----- Only 0    
 
 
 I changed option from SWS_BICUBIC to SWS_FAST_BILINEAR It seems and my question has been 2  
  Fixed ent sws_flags = SWS_BICUBIC; Structures swinstex * img_convert_ctx; Img_convert_ctx = sws_getcontext (pVCtx-> width, pvtx-> height, pvtx-> pix_fmt, pVCtx-> width, pvtx-> height, pixelformat :: PIX_FMT_BGR24, sws_flags, NULL, NULL, NULL) Static Ent sws_flags = SWS_FAST_BILINEAR; Structures swinstex * img_convert_ctx; Img_convert_ctx = sws_getContext (pVCtx- & gt; width, pVCtx-> height, pVCtx-> pix_fmt, pVCtx-> width, pVCtx-> height, PixelFormat :: PIX_FMT_BGR24, sws_flags, zero, zero, Zero);

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

Matlab: Transfer variable from GUI to Base Workspace and new Variables (Static Workspace, Script, Creating new Variables) -

-
I am developing a GUI for the current script, which expects some straight values ​​in the base workspace. The GUI will move users' values ​​to the base-workspace and then the script will start and close itself immediately. It sounds very easy and has values ​​that run with Essenin and Evelyn, but I work for days with the problem that if the script takes the values ​​of my post, then I get a message: Try to add var_name View MATLAB programming for static workspace details, see restrictions on assigning at variables. What's the problem? The GUI is closed and the script will use the base-workspace without restriction. How can this be done? The script is untouchable (not mine) and this base expects variables in the workspace, so the GUI is moving the value in the workspace and nothing else. A stable workspace is not required Workspaces will be free of any restrictions. To summarize: I want to delete "Static" in the "static workspace" Specifies the...
