Getting error "DLL load failed while importing rect : %1 is not a valid Win32 application" while importing package
17 août 2020, par Sagar DonadkarI am using cython package to call Cpp API and in my cpp code i am using ffmpeg library and able to build my code successfully using bellow command

Trying to convert an RTSP stream to a HSL file, but get a "Failed to Open Segment" error
1er juin 2021, par Alvydas JuodikisThese are the linux commands I ran on ubuntu 20.04 to convert an rtsp stream to a HLS file. I was trying to then display it onto my html webserver to run a live video but I'm stuck at an error.


ffmpeg -fflags nobuffer \
 -rtsp_transport tcp \

 -vsync 0 \

 -vcodec copy \
 -movflags frag_keyframe+empty_moov \

 -segment_list_type m3u8 \
 -segment_list_entry_prefix Home/Desktop/fmpegsolution/ \
 Home/Desktop/fmpegsolution/%3d.ts
</my>

I'm using an example from this link :
https://girishjoshi.io/post/ffmpeg-rtsp-to-hls/


I try to generate my file into a directory located in my desktop called fmpegsolution (hence the output path Home/Desktop/fmpegsolution)


The error :


When running this on terminal, the error comes out to :

[segment @ 0x558c82e11ec0] Opening 'Home/Desktop/fmpegsolution/000.ts' for writing [segment @ 0x558c82e11ec0] Failed to open segment 'Home/Desktop/fmpegsolution/000.ts' Could not write header for output file #0 (incorrect codec parameters ?): No such file or directory

My issue is related to the folder or directory but it definitely exists. I even tried creating a "%3d.ts" blank file (000.ts) but that had no effect. Could use some help. Thanks for your time.
