FFMPEG is not pushing the HLS chunks to remote server

[George Stoyanov]

Summary of the bug:
I am trying to create an HLS stream and to upload the HLS chunks and the manifest files to a remote server running NGINX using the HTTP PUT method. The script is working properly if I don't set up "-hls_segment_filename "index%04d.ts"" but when this option is present ffmpeg is not pushing the TS chunks to the remote server. On my remote server I see only the manifest files to be pushed, but not the chunks, at the same time I am seeing the chunks on the ffmpeg log:

[hls @ 0x559bceac83e0] Opening 'index0021.ts' for writing=N/A speed=1.49x
[hls @ 0x559bceac83e0] Opening 'index0022.ts' for writing=N/A speed=1.47x
[hls @ 0x559bceac83e0] Opening 'index0023.ts' for writing=N/A speed=1.47x
[hls @ 0x559bceac83e0] Opening 'index0024.ts' for writing=N/A speed=1.49x
[hls @ 0x559bceac83e0] Opening 'index0025.ts' for writing=N/A speed=1.51x

The /var/www/log/nginx/access.log on the remote machine is:

• - [28/Jun/2017:12:53:49 +0000] "PUT /vod/index.m3u8 HTTP/1.1" 204 0 "-" "Lavf/57.71.100"
• - [28/Jun/2017:12:53:52 +0000] "PUT /vod/index.m3u8 HTTP/1.1" 204 0 "-" "Lavf/57.71.100"
• - [28/Jun/2017:12:53:54 +0000] "PUT /vod/index.m3u8 HTTP/1.1" 201 0 "-" "Lavf/57.71.100"

But in the same time the index.m3u8 file looks fine and all the chunks are defined with their name:

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:6
#EXT-X-MEDIA-SEQUENCE:0

debbug log file from ffmpeg

[George Stoyanov]

I have added the debug.log file from ffmpeg. I have also noticed that the chunks are not sent to the remote machine, but rather saved on the local machine.
