Default stream selection does not work with HLS output

[Neal McConnell]

OS: CentOS 6.3 64-bit
Build: ffmpeg version N-49571-gb5f544a
Type: Burek static build, 64-bit, 20130204
Obtained from: ​http://ffmpeg.gusari.org/static/64bit/

I am attempting to encode from file(mainly MP4) to HTTP Live Streaming(HLS) compatible streams.

According to the FFmpeg documentation, ​http://ffmpeg.org/ffmpeg.html#Stream-selection:

By default ffmpeg includes only one stream of each type (video, audio, subtitle) present in the input files and adds them to each output file. It picks the "best" of each based upon the following criteria; for video it is the stream with the highest resolution, for audio the stream with the most channels, for subtitle it’s the first subtitle stream. In the case where several streams of the same type rate equally, the lowest numbered stream is chosen.
I should not have to map audio and videos streams when outputting to HLS.

I obtained a source file, so I could enter this report, from:

​http://www.wowzamedia.com/_h264/bigbuckbunny_1500.mp4

The problem I encountered is when attempting to encode to HLS, without mapping audio and video streams, a message appears:

Output file #0 does not contain any stream

If I set the output to mpegts or MP4, I receive no such message, and encode completes normally, which means that auto stream selection functioned as described in the documentation for those outputs.

Here is the exact command used:

./ffmpeg.20130204 -report -i ./source_media/bigbuckbunny_1500.mp4 -frames:v 480 -c:v libx264 -crf 25 -profile:v baseline -g 48 -sc_threshold 0 -flags +cgop -c:a aac -strict -2 -b:a 112k -f ssegment -segment_time 10 -segment_format mpegts "hls_%02d.ts"

Here is the report:

This issue remains.
I used a Burek 64-bit Linux static build for 2013.06.14.
Automatic stream selection of input streams does not work when the output is HLS.
It still says "Output file #0 does not contain any stream"

I think there was some confusion over what this bug report is about. It's about auto selecting(mapping) input, not output.

iam pretty sure it was fixed but maybe it broke again
