While waiting for the input stream to become ready, ignore all
commands except STOP. This fixes seeking errors with (remote) songs
which the decoder has already finished.
skip_symlinks() expects an UTF-8 encoded file name, but
updateDirectory() passed ent->d_name (in file system encoding) to it.
Convert it to UTF-8 first.
HTTP servers respond with "416 Requested Range Not Satisfiable" when a
client attempts to seek to the end of the file. Catch this special
case in input_curl_seek(). This fixes a glitch in the ogg vorbis
decoder plugin.
Since we are using curl_multi_info_read() / CURLMSG_DONE for detecting
end-of-response, we can remove all running_handles==0 checks. For
some reason, that has never worked correctly.
curl_multi_info_read() is the authoritative source of the
"end-of-response" information. Always set c->eof when a CURLMSG_DONE
message is received, and check the result (success/failure) after
that.
The goal is to have one structured document which is the authoritative
protocol specification. The documentation which currently resides in
the wiki will be merged.
When a global audio format is configured (setting
"audio_output_format"), decoder_data() overwrote the "length"
parameter with the size of the output buffer (result of
pcm_convert_size()). Declare a separate variable for the output
buffer length.
neaacdec.h declares all arguments as "unsigned long", but internally
expects uint32_t pointers. This triggers gcc warnings on 64 bit
architectures. To avoid that, make configure.ac detect whether we're
using Debian's corrected headers or the original libfaad headers. In
any case, pass a pointer to an uint32_t, conditionally casted to
"unsigned long*".
alloca() is not a portable function. Don't use it. Using
strncasecmp() is much more efficient anyway, because no memory needs
to be allocated and copied.
Don't send a "next song" request to the main thread when the current
song hasn't started playing yet, i.e. there are already two different
songs in the music pipe. This would erase information about the song
boundary within the music pipe, and thus triggered an assertion
failure. The bug could occur when playing very short songs which fit
into the pipe as a whole.
Fix a deadlock: when the decoder waited for buffer space, the player
could enter a deadlock situation because it waits for more chunks for
crossfading chunks. Signal the decoder before entering notify_wait().
The wavpack open function gives us an option called OPEN_STREAMING. This
provides more robust and error tolerant playback, but it automatically
disables seeking. (More exactly the wavpack lib will not return the
length information.) So, if the stream is already not seekable we can
use this option safely.
Seeking was somewhat broken in some decoder plugins because they sent
empty chunks, and never got a command. Check the decoder command
before doing anything else in decoder_data().
