[FFmpeg-user] FFMPEG 3.2.2 - "could not find codec parameters"

[Caio Cesar Moreira]

Hi,

I'm trying to dump video frames from a TS file but for some reason ffmpeg
is failing.

Command used: ffmpeg -i playlist.m3u8 -vcodec -r 1 "output_%04d.png"
-loglevel 99

m3u8 content:

#EXTM3U

#EXT-X-VERSION:3

#EXT-X-TARGETDURATION:5

#EXT-X-MEDIA-SEQUENCE:160983

#EXT-X-PROGRAM-DATE-TIME:2016-12-17 13:08:01+00:00

#EXT-X-KEY:METHOD=AES-128,URI="key.bin"

#EXTINF:5.0000,

myfile.ts

#EXT-X-ENDLIST

myfile.ts and key.bin are in the same folder as the m3u8 file.

I tried an older version of FFMPEG (3.1.5) and I get another error message
for the same command line, which is: Output file #0 does not contain any
stream.

Any idea of what's going on?
Thanks in advance!
