Yeah, this is just great. Flash being so popular, this definitely helps
Python's popularity as a real server plateform alternative for such
applications.

Again, congrats with the project !

Hi,

I tried to use this version for the wiidiaplayer today, and ran into a small problem. After I strip the header from an RTMP packet, I'm left with a concatnation of an unknown number of amf-encoded variables. It seems that pyamf.decode expects the encoded stream to be a single encoded list (hence the yield of each element of the initial call to Decoder.readElement()).

I got it working fine now by changing the pyamf.decode function to:

    decoder = _get_decoder_class(encoding)(stream, context)
   
    while True:
        try:
            yield decoder.readElement()
        except exceptions.EOFError:
            break

My AMF packet looks like this:

"\x02\x00\x07connect\x00?\xf0\x00\x00\x00\x00\x00\x00\x03\x00\x03app\x02\x00\x00\x00\x08flashVer\x02\x00\x0cLNX 9,0,31,0\x00\x06swfUrl\x02\x00&http://localhost:8080/wiidiaplayer.swf\x00\x05tcUrl\x02\x00\x10rtmp://localhost\x00\x04fpad\x01\x00\x00\x0baudioCodecs\x00@\x838\x00\x00\x00\x00\x00\x00\x0bvideoCodecs\x00@_\x00\x00\x00\x00\x00\x00\x00\rvideoFunction\x00?\xf0\x00\x00\x00\x00\x00\x00\x00\x07pageUrl\x02\x00' http://localhost:8080/wiidiaplayer.html\x00\x00\t"

It should decode to 3 variables:
connect
1.0
{'videoCodecs': 124.0, 'audioCodecs': 615.0, 'flashVer': u'LNX 9,0,31,0', 'app': u'', 'swfUrl': u' http://localhost:8080/wiidiaplayer.swf', 'videoFunction': 1.0, 'pageUrl': u'http://localhost:8080/wiidiaplayer.html', 'fpad': False, 'tcUrl': u'rtmp://localhost'}


Perhaps I'm missing something and there is another way to do this?

Hi Reinoud,

pyamf.encode and pyamf.decode were slightly misguided, but r626 changes that. Continue to use decode as you were, it should give you better results now.

I took inspiration from your code change for the actual fix, thanks!

Thanks Nick,

r627 works fine in my code, I use it for both encoding and decoding now.

I'm still tracking a bug that occurs when I unpause the stream after a real long time (hours). This problem was present in the very early version of PyAMF, and still persists. Then again, perhaps the parsing of the RTMP packet may just be failing and not producing an error.

I added some more debugging statements to my application, hopefully I can show you the packet it crashes on tomorrow.

Hi Reinoud,

pyamf.encode and pyamf.decode were slightly misguided, but r626 changes that. Continue to use decode as you were, it should give you better results now.

I took inspiration from your code change for the actual fix, thanks!

Hi,

I tried to use this version for the wiidiaplayer today, and ran into a small problem. After I strip the header from an RTMP packet, I'm left with a concatnation of an unknown number of amf-encoded variables. It seems that pyamf.decode expects the encoded stream to be a single encoded list (hence the yield of each element of the initial call to Decoder.readElement()).

I got it working fine now by changing the pyamf.decode function to:

    decoder = _get_decoder_class(encoding)(stream, context)
   
    while True:
        try:
            yield decoder.readElement()
        except exceptions.EOFError:
            break

My AMF packet looks like this:

"\x02\x00\x07connect\x00?\xf0\x00\x00\x00\x00\x00\x00\x03\x00\x03app\x02\x00\x00\x00\x08flashVer\x02\x00\x0cLNX 9,0,31,0\x00\x06swfUrl\x02\x00&http://localhost:8080/wiidiaplayer.swf\x00\x05tcUrl\x02\x00\x10rtmp://localhost\x00\x04fpad\x01\x00\x00\x0baudioCodecs\x00@\x838\x00\x00\x00\x00\x00\x00\x0bvideoCodecs\x00@_\x00\x00\x00\x00\x00\x00\x00\rvideoFunction\x00?\xf0\x00\x00\x00\x00\x00\x00\x00\x07pageUrl\x02\x00' http://localhost:8080/wiidiaplayer.html\x00\x00\t"

It should decode to 3 variables:
connect
1.0
{'videoCodecs': 124.0, 'audioCodecs': 615.0, 'flashVer': u'LNX 9,0,31,0', 'app': u'', 'swfUrl': u' http://localhost:8080/wiidiaplayer.swf', 'videoFunction': 1.0, 'pageUrl': u' http://localhost:8080/wiidiaplayer.html', 'fpad': False, 'tcUrl': u'rtmp://localhost'}

It seems the flash player doing a strange call after a long pause, which the RTMP parser parses incorrectly (or rather: it looks like the call is being parsed correctly but the data just doesn't make sense....). So it's not PyAMFs fault.

In case someone is interested (I'm crossposting to rtmpy), this is the call I receive:

0x0000  88 ff ff ff 02 1e 44 73   02 00 05 70 61 75 73 65         . . . . . . D s   . . . p a u s e
0x0010  00 00 00 00 00 00 00 00   00 05 01 00 00 40 a2 12         . . . . . . . .   . . . . . @ . .
0x0020  00 00 00 00 00                                            . . . . .

Which I decode as 4-byte header, channel_id=8, timestamp =16777215, and the rest is AMF packet (of size 29 since the last call had size 29). It would be decoded correctly if we had an 8-byte-header, channel_id is correct, timestamp should be something like 39600 (11 hours), size should indeed be 29, and kind 20, so I had expected the following header:

48 00 9a b0 00 00 1d 14

Until I solve this, no long pauses I guess :)
