hls uses wrong path separator in DELETE method

[Peter Holliday]

Summary of the bug:

When uploading hls segmented video to a web server, the PUT/POST commands are correct but the DELETE method uses a backslash '\' character instead of a forward slash '/' character before the filename.

ffmpeg Command (Win x64):

.\ffmpeg.exe -re -i "Test.mp4" -c:v libx264 -f hls -force_key_frames "expr:gte(t,n_forced*1)" -hls_time 2 -hls_list_size 3 -hls_delete_threshold 2 -hls_allow_cache 1 -hls_segment_type mpegts -hls_flags independent_segments+delete_segments -method PUT ​http://localhost:5251/hls/out.m3u8

Log from RHEL server (Apache 2.4):
tail -f /var/log/httpd/access.log

I have not tried Linux ffmpeg executable, but it appears the Win version is using a windows file separator instead of the conventional forward slash for http.

Same problem. Did you find the issue?

[Peter Holliday]

Haven”t gone through the ffmpeg code (don”t have the time). I wrote my own middleware to intercept the request and fix the problem on my side.

I'm getting the same issue; I have tested in Linux and Mac and its only happening in the Windows version.
