* libstagefright: Use 3gp4 ftyp box when AMR audio is presentLeena Winterrowd2015-10-061-0/+3
| | | | | | | | | | | mp42 boxes do not support the 'damr' box type whereas 3gp4 boxes explicitly support it. Using mp42 makes clips with AMR incompliant with mpeg4 standards and unplayable by many media players. To ensure interoperability, use a 3gp4 box if the recorded clip contains AMR audio.

| | | | | | | MediaPlayerService can't open files (it needs an already opened file descriptor), so these were just wasting space. Change-Id: I323044a6c1814a7bff952ed71b5c7792df2abf03

* MediaMuxer prefer not to use the MPEG4Writer in real time recording mode.ztenghui2013-04-151-0/+8
| | | | | | | | By default, MPEG4Write will keep running in real time recording mode. bug:8598944 Change-Id: Idf7fbd4e0feb7763660a74279ba8817b79098aaf
* Make limitations of MPEG4Writer explicitJames Dong2013-03-141-0/+6
| | | | | | | | | | | | | | o No more than 2 tracks will be supported o No more than one video and/or one audio tracks will be supported o Only take video and/or audio track (for instance, no text tracks) o If there is no track before start() is called, bail out. At the same time, make sure the errors from addSource() report to addTrack(), not to start(). Bug: 7991013 Change-Id: I1ca35aaeb75b5448d75ed2c6c10dd12ecea720ab
* Store correct time stamps in recorded mp4 filesJohannes Carlsson2012-07-301-0/+2
| | | | | | | | | | | | | | According to the specification (ISO_IEC_14496-12_2008 page 17, 19 and 21) the time is "in seconds since midnight, Jan. 1, 1904, in UTC time" which is not the same as Unix epoch time. This is already correctly handled in MPEG4Extractor.cpp when reading files. The specification also supports 64 bit timestamps which would make it a bit more future proof, but unfortunately it seems like support for this in players are poor (tested both Windows media player and Quicktime player).

* Don't call virtual functions in destructors for the writer classesJames Dong2012-02-021-1/+2
| | | | | | | Have not found any concrete bugs related to these calls yet, but we should avoid calling virtual functions in destructors, regardless. Change-Id: I2d47b79d3fb2d29f418619bee83aa147d232a5d4

* Rotation supportJames Dong2010-11-091-0/+1
| | | | | | | | | | | | | | - We only support 0, 90, 180, and 270 degree clockwise rotation - Some players are known to ignore composition matrix in the MP4 file, although this is part of the MP4 file standard. Both QT and YT are supporting the rotation The original patch (65a73f4e8c79d05c0d9001b660325748d4ecf37b) was not merged. The only change I made is to reuse the same kKeyRotation in MetaData.h; and thus do not neeed to use kKeyRotationDegree. Change-Id: Ib328716d4842201c4adf57e4ddfe1f1ac1ae4d8a
* File writer size estimation improvementJames Dong2010-10-191-0/+1
| | | | | | | | | | | | | | o Do not count the reserved space for moov if the meta data size is small o Do not count the extra 1KB disturbing small file estimation. o Reduce the default minimum reserved space from 4 KB to 3 KB. o Estimate the moov size based on both duration AND file size limit is set and set it to the smaller estimated value. low risk change bug - 3111983 Change-Id: I6ac2adb979d8cc12d6b4f1813d000c989add0199
* Fixed an issue where the reserved free space in the file writer was larger ↵James Dong2010-10-041-0/+1
| | | | | | | | | | | | | | | than intended The problem was that even though user does not explicitly request the max file size limit via MediaRecorder.setMaxFileSize(), the file writer sets an implicit file size limit if 32-bit file offset is used on user's behalf. The reserved free space is estimated based on the file size, if the file size limit is set by the user. The fix is to add an extra bool to tell the difference between an explit requested file size and an implicit file limit and use that to set the estimated moov box size accordingly. Change-Id: I731aca6c7833aa764ed7b905edb77721577471b3
* Remove unused/debugging code from MP4 file writerJames Dong2010-09-031-0/+5
| | | | | | o also makes nal length in the recorded file modifiable at runtime Change-Id: I731b4dde7070d8d9628b36b523a5b2c011c7c2cf
* Better file size estimateJames Dong2010-09-021-0/+1
| | | | | | | | | When the recorded file becomes large, the metadata size can no longer be ignored. This makes it possible to save the recorded file when the storage becomes almost full at the end of the recording session. Change-Id: Ief038080f825c9946ce550949c03e914aec1e31a
* Calculate audio media drift time from AudioSourceJames Dong2010-09-011-1/+1
| | | | | | | | | | | | | | | | | | | The problem was that the time to receive an output buffer from an audio encoder is different because the encoder does not need to read from the source for all output buffers. This leads to large fluctuation in terms of wall clock duration between two neighboring audio sample outputs from the audio encoder. As a result, the media time for the video track after adjustment using the drifting changes wildly sometimes. This patch addresses this issue by only updating the media drift time when an audio source input buffer is read. the wall clock for the audio track is also calculated at the same time when the input audio buffer is read at AudioSource. bug - 2959800 Change-Id: I3174aa182f744784b540f0a7198524d4eee8bd7b

* Make MediaWriter stop and pause return errors if necessaryJames Dong2010-08-191-2/+2
| | | | | | | | | | | o Make the API consistent with SF framework, which the MediaSource provides a return status for stop o Also, helps to convey errors that occurred right when a premature stop() is called, leading to a potentially mal-formed output file. Change-Id: I52a932345f38570fdf8ea04d67d73dd94ccd30ef
* Use audio clock as the reference media clockJames Dong2010-08-131-0/+6
| | | | | | | | | | | | o Only do this for realtime applications o Adjust other track clock based on audio clock o Assume other track uses wall clock as the media clock o Use some heuristics to reduce the size of stts box by 2/3. - also o Remove one unused key from MetaData.h Change-Id: Ib9432842627b61795b533508158c25258a527332
* File writer has a designated writer thread nowJames Dong2010-08-021-0/+41
| | | | | | | | + This reduces the file I/O block time for audio/video track processing - Since the file writer is buffering some output samples, the memory usage would go up, depending on how many output samples are buffered. Change-Id: I780cc5b26f4b53a5efbd643fcf9505dfc19cd4cd
* Progress status notificationJames Dong2010-07-201-0/+1
| | | | | | - Keep track of per-track progress Change-Id: Ibd36f0e8c78581928c8aa2f5e23c5e7e0615c2cc
* Support user-supplied timescales for authoringJames Dong2010-07-141-0/+2

* Provide progress status report during authoringJames Dong2010-06-251-1/+1
| | | | | | | | | - Track either the number of A/V frames authored, or the time elapsed - Track the completion of the authoring - Add multiple camera support for authoring by accepting a camera id parameter - Set file type based on the OUTPUT_FORMAT requested Change-Id: I0f9d31b3b7a8fa43eb53f572410fb0ebd4fa0bb7
* Enable passing parameters to the MediaWriter at runtime (at start() call).James Dong2010-06-251-1/+2
| | | | | | | | | | - estimate the moov box size for mp4 file writer based on the file size/duration limit and target bit rate. - can switch to use 64 bit file offset at runtime rebased Change-Id: Ibbe1f57e91ab2605820d5d96e8048d11e5559c53
* Fixed some meta data issues in the recorded mp4 fileJames Dong2010-06-231-0/+1
| | | | | | | | | | | | | | - Mainly correcting the location of stbl box which should be a child of minf box. This resolved the issue where the mis-muxed encoded file could not be played by QT/VLC. - Enabled the the recorded tracks by setting the flags to 0x07 by default - Allows for encoding either 32-bit or 64-bit offsets. By default encoding 32-bit offsets to reduce the metadata overhead - Fixed a edts box issue where an empty elst box was used at the end Change-Id: I570621a26714a81dc9400271aa5d3a07b483172f
* Single track optimizationJames Dong2010-06-221-0/+1
| | | | | | | | We don't need to do interleave when the total number of tracks to be recorded is one. Metadata-wise, we only need to have one chunk in chunk offset table, and a single entry in the stsc table. Change-Id: I46f0e4b3860620311e7a91b68a9067acaa137bb2
