* All muxers (mp4, webm and ogg) are affected
* solve some checkstyle's errors (building was blocked)
Mp4FromDashWriter:
* drop "writing application"
* drop "handler name"
OggFromWebMWriter:
* drop "writing application" for OPUS and VORBIS header
WebMWriter:
* Drop "Muxing application"
* Drop "Writing application"
* read "SeekPreRoll" from the source track (if available)
* use the longest track duration as segment duration, instead of the video track duration
* do not hardcode the "Cue" reserved space behavior
* do not hardcode the "EBML Void" element, unreported issue. The size was not properly calculated
* rewrite the key-frame picking
* remove writeInt(), writeFloat() and writeShort() methods, use inline code
* set "SeekPreRoll" and "CodecDelays" values on output tracks (if available)
* rewrite the "Cluster" maker
* rewrite the code of how "Cluster" sizes are written
Fix encode() method (the reason of this commit/pull-request):
* Use the unsigned shift operator instead of dividing the value, due precession lost
* migrate few annotations to androidx
* mission recovery: better error handling (except StreamExtractor.getErrorMessage() method always returns an error)
* post-processing: more detailed progress
[file specific changes]
DownloadMission.java
* remove redundant/boilerplate code (again)
* make few variables volatile
* better file "length" approximation
* use "done" variable to count the amount of bytes downloaded (simplify percent calc in UI code)
Postprocessing.java
* if case of error use "ERROR_POSTPROCESSING" instead of "ERROR_UNKNOWN_EXCEPTION"
* simplify source stream init
DownloadManager.java
* move all "service message sending" code to DownloadMission
* remove not implemented method "notifyUserPendingDownloads()" also his unused strings
DownloadManagerService.java
* use START_STICKY instead of START_NOT_STICKY
* simplify addMissionEventListener()/removeMissionEventListener() methods (always are called from the main thread)
Deleter.java
* better method definition
MissionAdapter.java
* better method definition
* code cleanup
* the UI is now refreshed every 750ms
* simplify download progress calculation
* indicates if the download is actually recovering
* smooth download speed measure
* show estimated remain time
MainFragment.java:
* check if viewPager is null (issued by "Apply changes" feature of Android Studio)
* OggFromWebMWriter: rewrite (again), reduce iterations over the input. Works as-is (video streams are not supported)
* WebMReader: use int for SimpleBlock.dataSize instead of long
* Download Recovery: allow recovering uninitialized downloads
* check range-requests using HEAD method instead of GET
* DownloadRunnableFallback: add workaround for 32kB/s issue, unknown issue origin, wont fix
* reporting downloads errors now include the source url with the selected quality and format
* correct calculation of "co64" box and usage of 64bits offsets
* generate one chunk for audio streams like ffmpeg does, attempt to fix cut-off audio
* misc. cleanup
* reduce the number of iterations over the output file (less seeking)
* fix audio samples with size of 255 do not handled correctly in the segment table (allows writing audio streams with 70kbps and 160kbps bitrate)
* add support for VORBIS codec metadata
* write packets based on the timestamp
