#6092: FFMpeg cannot deal the http streamed file
-------------------------------------+-------------------------------------
Reporter: ChaoYugang | Type: defect
Status: new | Priority: normal

-------------------------------------+-------------------------------------
Summary of the bug:
If the http head has "Transfer-Encoding:chunked",
the ffmpeg's process_line function deal it,
then set "s->filesize=-1" and "s->chunksize=0".
This show the file is streamed,
but in http_read_header function in http.c file it does not set
"h->is_streamed = 1".
We test it should add the codes in http_read_header function before the
codes "cookie_string(s->cookie_dict, &s->cookies);":
if( h->is_streamed==0 && s->filesize==-1 ){
av_log( 0, AV_LOG_ERROR, "[%s:%d] fixed bug for
is_stream&filesize\n",__FILE__,__LINE__);
h->is_streamed = 1;
}
How to reproduce:
I am sorry I have not know how to reproduce it.
I will continue to find the reproduce method.
Or you may modify the codes in http_read_header function, add the codes:
s->filesize = -1;
s->chunksize = 0;
Then use build a new ffmpg lib,use the new lib to open a http mp4 file.
