Description (last modified by saste)
Summary of the ticket:
add support to EXT-X-STREAM-INF and BANDWIDTH field in the generated M3U8 output.
Here is spec from http://tools.ietf.org/html/draft-pantos-http-live-streaming-07
BANDWIDTH
The value is a decimal-integer of bits per second. It MUST be an
upper bound of the overall bitrate of each media segment (calculated
to include container overhead) that appears or will appear in the
Playlist.
Every EXT-X-STREAM-INF tag MUST include the BANDWIDTH attribute
Here is command line:
C:\ffmpeg\ffmpeg.exe -re -i "rtmp://bar/foo.flv" -y -c:v copy -c:a copy -hls_time 6 -hls_list_size 5 -hls_wrap 30 -start_number 1 "C:\Tools\Foo\stream.m3u8"

To the best of my knowledge, there is no bug: BANDWIDTH only exists within EXT-X-STREAM-INF which is optional and not written by FFmpeg.
Please reopen the ticket if you can clarify your issue.

I guess you are right, it should be a feature to write out EXT-X-STREAM-INF. Changing ticket into feature request.

- Description modified (diff)
- Keywords segment m3u8 added
- Summary changed from m3u8 file generated is not up to published specs to print EXT-X-STREAM-INF and BANDWIDTH in output M3U8
I don't see an EXT-X-STREAM-INF element in m3u8 files produced by FFmpeg - please provide your command line, your complete, uncut console output and the m3u8 file to make this a reproducible ticket.
