  • Automatic encoder selection failed for output stream #0:1

    I’m trying to use ffmpeg for edit some videos on android...
    It is working fine but if I try to use drawtext i get error

    the command is :

    path/ffmpeg -y -i /path/asd.mp4 -map 0 -segment_time 15 -f segment -c:v libx264 -preset veryfast -crf 30 -vf "drawtext=text='test message ':fontfile=/path/arial.ttf:box=1:boxborderw=30:boxcolor=0xE86F67@0.7:fix_bounds=true:fontcolor=0x2A363B:fontsize=32:x=0:y=h" -r 30 -force_key_frames expr:gte(t,n_forced*15) -an /path/temp%03d.mp4

    and the error is :

 Automatic encoder selection failed for output stream #0:1. Default encoder for format segment (codec none) is probably disabled. Please choose an encoder manually.
    
 Error selecting an encoder for stream 0:1

    things to considere :
    1. I’ve checked 3 times all the paths are valid
    2. I’ve tested the same command on ffmpeg 4.0 on windows and it works [with the same video]
    3. If I remove the drawtext filter it works fine...

    I tought it ffmpeg was built without drawtext or with some error so i spent 10 days in order to build it bymyself and guarantee every dependency is ok... but at end i got the same error

    does anyone have any idea please

    ==============================
    UPDATE

    I keep testing and if I remove the quotes from the filter and use a text without spacing it works

    ex :
    drawtext=text='test_message':fontfile=/path/arial.ttf:box=1:boxborderw=30:boxcolor=0xE86F67@0.7:fix_bounds=true:fontcolor=0x2A363B:fontsize=32:x=0:y=h

    so I believe there is something related to how android is escapes quotes and simple quotes because i compiled ffmpeg with same parameters and it runs on ubuntu with spaces at the text (just need to use simple quotes)

    does anyone know about it ?

  • How do I convert RTSP stream for iOS browser viewing

    27 juin 2018, par humble_coder

    TL ;DR

    I need to convert full RTSP (A/V) stream from Axis IP cameras to be viewed in a fully-contained/not-full-screen div in an iOS browser. Think : "Youtube live stream as viewed from iOS browser". I’ve seen several links that hint at the issue. . .

    . . .but they’re either "incomplete" or out of date.

    The solution must be local and remain behind site firewall (so no external services).

    MORE DETAIL

    I’m currently writing a custom "Axis IP Camera Manager" Vue/Laravel web app for a client. The initial requirements were very simple :

    1. scan network for axis devices and store addresses/info for future use

    2. display grid of MJPEG for selected camera(s).

    The initial requirements were fairly straightforward. Now, though, there are additional requirements :

    1. Record RTSP stream to [seconds] long MP4 streams.

    2. Convert an RTSP stream from AXIS IP CAMERA to something viewable in both desktop and mobile browsers with full A/V.

    I’ve successfully managed #3 by using ffmpeg to capture and store the stream to MP4. However, I’m no video aficionado, and the nature of #4 is still a bit fuzzy to me. Per my understanding I can’t watch RTSP streams in a browser in iOS, but I also can’t stream an "in-process" MP4 over HTTP. I’ve seen references to several items such as Red5, Live555, Wowza, ffserver (discontinued ?), etc. but I’m completely unfamiliar with them. In the short term, I’m looking for a quick "live" conversion solution. In the long term, I’m interested in a deeper understanding of the issue(s) at hand. Any current info/expertise/links/manuals would be appreciated.
