FfmpegDecoderPlugin: av_seek_frame not returning #909

Closed geneticdrift closed 4 years ago

geneticdrift commented 4 years ago

Bug report

Describe the bug

When starting MPD with state state: play and time: xxxx.xx when the current track is a stream without a duration (av_stream.duration = 0x8000000000000000 (AV_NOPTS_VALUE)), the call to av_seek_frame in FfmpegDecode never returns or fails (depending on the value of time: xxxx.xx).

It looks like the bug is in ffmpeg, but may be MPD can work around it somehow, perhaps not try to seek if the stream has no duration?

Expected Behavior

MPD start playing the stream either where is left off or restart it if seeking failed.

Actual Behavior

MPD is not responsive as ffmpeg keeps seeking the stream for unknown time (waited minutes). It seem that small values of time (time: < 5) result in decoder error, but larger vaues e.g. 60 keep seeking for a long time.

It is reproducible with this state file (this state file was result of playing the stream then pausing and terminating MPD after it wrote the state file):

sw_volume: 15
audio_device_state:1:ALSA dmixer
state: play
current: 0
time: 135.00
random: 0
repeat: 0
single: 0
consume: 0
crossfade: 1
mixrampdb: 0.000000
mixrampdelay: -1.000000
playlist_begin

song_end
playlist_end

The second stream is working (change current to 1) but it takes different code path and it has a duration while the first does not have a duration.
