HI.

I'm trying to decode h.264 raw stream without PPS SPS.

For encoding parameters, some extradata is being delivered from another session.

But while trying to add extradata bytes manually, the script returns the error below.

line 392, in initialize_ffmpeg_video
av_codec_ctx.extradata = extradata
File "av/codec/context.pyx", line 103, in av.codec.context.CodecContext.extradata.set
AttributeError: 'av.bytesource.ByteSource' object has no attribute 'size'

this code block in av/codec/context.pyx causes the issue.

I have changed the line that is allocating extradata_size to

self.ptr.extradata_size = len(data)

then, it works.

in bytesource.pyx, there is no attribute 'size' for bytesource object.

The original commit from issue #287 by @adavoudi includes the working code.
(commit 51a7385 on 25 Feb)

   def __set__(self, data):
       buffer_size = len(data)
       cdef ByteSource source = bytesource(data)
       self.ptr.extradata =  <uint8_t *>malloc(buffer_size * sizeof(uint8_t))
       self.ptr.extradata_size = buffer_size
       memcpy(self.ptr.extradata, source.ptr, buffer_size)

but it has been changed in merged commit 4b01b63 on 23 Mar.

please check it out.

Thanks.
