* avformat/mp3dec: improve junk skipping heuristicwm42015-10-201-7/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 2b3e9bbfb529e6bde238aeb511b55ebe461664c8 caused problems for a certain API user: https://code.google.com/p/chromium/issues/detail?id=537725 https://code.google.com/p/chromium/issues/detail?id=542032 The problem seems rather arbitrary, because if there's junk, anything can happen. In this case, the imperfect junk skipping just caused it to read different junk, from what I can see. We can improve the accuracy of junk detection by a lot by checking if 2 consecutive frames use the same configuration. While in theory it might be completely fine for the 1st frame to have a different format than the 2nd frame, it's exceedingly unlikely, and I can't think of a legitimate use-case. This is approximately the same mpg123 does for junk skipping. The set of compared header bits is the same as the libavcodec mp3 parser uses for similar purposes.

* avformat/hls: fix segment selection regression on track changes of live streamsAnssi Hannula2015-10-151-0/+1
| | | | | | | | | | | | | | | | | Commit ad701326b43078b90 ("avformat/hls: open playlists immediately when AVDISCARD_ALL is dropped") inadvertently caused first_packet to never be cleared, causing select_cur_seq_no() to not use the specific code for live streams. In practice this means that when the user selects a different audio track during live stream (i.e. non-VOD) playback, there may be some additional delay as the code might select an incorrect segment at first, and we have to wait for video to catch audio (if too late segment was selected) or to download more following audio segments (if too early segment was selected). Fix that by restoring the zeroing of first_packet. (cherry picked from commit fd74d45d5158812675105a3b4aeb29c67b82f7e8)

* avcodec/mp3: fix skipping zeroswm42015-10-091-1/+3
| | | | | | | | | | | | | | | | | | Commits 43bc5cf9 and c5371f77 add code for skipping initial zeros in mp3 packets. This code forgot to report to the user that data was skipped at all. Since audio codecs allow partial packet decoding, the user application has to rely on the return value. It will remove the data reported as consumed by the decoder, and feed it to the decoder again. This resulted in the mp3 frame after the zero region to be decoded over and over again, until the zero region was finally skipped by the application. Fix this by including the amount of skipped bytes to the number of consumed bytes returned by the decode call. Fixes trac ticket #4890.
