Automatic encoder selection failed for output stream #0:1

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 0:1things 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
==============================
UPDATEI 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_coderTL ;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. . .
- Streaming via RTSP or RTP in HTML5
- RTSP tunneled HTTP, FFMPEG
- How can I display an RTSP video stream in a web page ?
- Embed RTSP Stream into Browser
. . .but they’re either "incomplete" or out of date.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 :
-
scan network for axis devices and store addresses/info for future use
-
display grid of MJPEG for selected camera(s).
The initial requirements were fairly straightforward. Now, though, there are additional requirements :
-
Record RTSP stream to [seconds] long MP4 streams.
-
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.
