  • How I can receive MJPEG stream via RTSP with resolution more than 1080p

    21 septembre 2018, par chuchuchu

    There is a problem :
    When I get a video stream with a resolution of 1080 and below - everything is fine.
    But if I select a stream with a resolution higher than 1080 on the camera, an error occurs.
    FFMPEG :

    [mjpeg @ 0x7f5488003e40] [IMGUTILS @ 0x7f5494acb4f0] Picture size 0x0 is invalid

    If I open a stream in the player I get a disparate image :

    [mjpeg @ 0x7fd9f8043b20] error y=91 x=16
    
[mjpeg @ 0x7fd9f8043b20] error dc

    I repeatedly recompiled and reinstalled various versions of the ffmpeg, the problem is not solved.

    I suspect that there is a restriction for video stream over 1080p, but I can not find any description or solution.
    And I found next string in rfc "RTP Payload Format for JPEG" :

    The maximum width is 2040 pixels.

    but it is dated 1998. I know for certain that this stream on the RTSP receives in the resolution I need, but I can not understand how.

    Please, tell me the way to the solution. I’m using Ubuntu 16.04 amd64.
    Perhaps there is an alternative way to receive a rtsp-stream without using a ffmpeg ?? Since all ways known to me are using ffmpeg.

  • downloaded a streaming video file from a website with ffmpeg in 1080p but i wanted to download in 720p as i have disk space limitations [on hold]

    22 octobre 2018, par C.J.

    I apologize if my language was unclear let me try to rephrase the question. I have downloaded a video from a video streaming website called "hotstar.com" with the help of ffmpeg. I extracted the m3u8 link from the site and was able to download it. The video is in 1080p video resolution which takes a lot of space. I want to download it in 720p resolution so that it would take less space. the code that i tried for it was this

    ffmpeg -i "https://hsprepack.akamaized.net/videos/hotstarint/world/kwks6/1_2/master.m3u8?hdnea=st=1540184067~exp=1540185867~acl=/*~hmac=a8945f016b594e1e2e4192ee05e2feaa5811c687d1891f69be1acc9057dd725f"
    
-c copy output.mp4

    I hope I have asked properly this time. If not do tell me what is more needed.

    I’m working on a video share service like youtube.com

    below item are important :
    1- i don’t know what quality the file have (1080p,720p,480p,360p)
    2- i don’t know what format the file have (MPEG4(mp4),flv,AVI,WMV)
    3- i have .str subtitle

    I need export with this Specification :
    1- .m3u8 output support all quality(1080p,720p,480p,360p) if input file quality support
    2- .ts files length be the best practice (2sec, 5sec, 10sec or other is better)
    3- output file support subtitle

    What is the best command(or commands) for create this output using ffmpeg ?
