[...] While you guys are at it, there are still a couple of samples that do not work in ffplay:
http://samples.mplayerhq.hu/A-codecs/GSM/sample-gsm-8000.gsm This one cant be recognized:
[mp3 @ 0x843b514]Could not find codec parameters (Audio: mp2, 8 kb/s) sample-gsm-8000.gsm: could not find codec parameters
What format is it?
I would guess it is raw GSM. You're the GSM expert, find out :)
Ah, but to-ast or not to-ast, that is the question (I *love* bad puns!) TOAST being the file format that comes with the Berlin implementation known as libgsm. IIRC 4 'magic' bits are prepended (or is it appended?) to every block of 33 bytes minus 4 bits. I really need to know the origin. Strangely http://samples.mplayerhq.hu/A-codecs/GSM/ states this file dates back to 2002-Aug-08, I doubt that very much. Time for sherlocking my list archives...
http://samples.mplayerhq.hu/A-codecs/GSM/sample-gsm-8000.mov This one works for me:
ffmpeg -i sample-gsm-8000.mov -vn -acodec pcm_s16le sample-gsm-8000.mov.wav
produces a wav with correct sound.
Hmm, disregard this, works fine now...
That is what you get for posting a problem without upgrading then posting your command line and messages :-)
