[FFmpeg-devel] Questions on adding a FATE test for the HLS muxer

[Raento Mika]

Hiy'all

As suggested by Michael, I'm trying to add a FATE test for the new
single_file option to the HLS muxer.

I have something working, but I'm not sure what's the best way to do this.
The wiki page is not very complete.

The HLS muxer produces a number of .ts files (well, one for the
single_file case) and a m3u8 file. The m3u8 is output several times during
the muxing.

The existing tests I found all use a single output, passing '-' as the
output filename to ffmpeg. Doing this generates a file that looks like

<ts contents for first segment><first m3u8 contents><ts contents for
second segment><second m3u8 contents>...

checking this against a reference file will indeed verify the whole
output, but is not very readable. Should I do this? And if so, how do I
add a new reference file to FATE.

The new fate .mak I have looks like

FATE_SAMPLES_AVCONV-$(call ALLYES, AAC_DECODER MPEG4_DECODER HLS_MUXER) +=
fate-hls-byterange 
                   
                   
                   
                   
fate-hls-byterange: CMD = ffmpeg -i $(SAMPLES)aac/al04_44.mp4 -f hls
-hls_flags single_file -c copy -
                   
fate-hls-byterange: REF = $(SAMPLES)hls/byterange
                   
                   

Does the config list look reasonable? I have a hard time verifying that
it's exhaustive without trying out a lot of different ./configure flags.

BR,

   Mika
