 Summary of the bug:
 How to reproduce:
 {{{
 ffmpeg -i input.ts -c copy -f hls -master_pl_name master.m3u8
 -var_stream_map "v:0,a:0" "vs_%v/playlist.m3u8"
 }}}

 input.ts is attached.
 This has been tested on ffmpeg compiled on 2018-09-05.


 What is wrong:
 FFmpeg fails to read the bitrate of the input.ts and thus fails to write
 the master.m3u8

 The code below is what controls this error.

 {{{
        if (!bandwidth) {
            av_log(NULL, AV_LOG_WARNING,
                    "Bandwidth info not available, set audio and video
 bitrates\n");
           return;
        }

 }}}


 My thoughts is that the proper way would not to return if bandwidth is not
 available but simply write the playlist without the bandwidth information
 since it was not available.
