* Fixed an issue where the reserved free space in the file writer was larger ↵James Dong2010-10-041-2/+14
| | | | | | | | | | | | | | | 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.

* Better file size estimateJames Dong2010-09-021-34/+103
| | | | | | | | | 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 Dong2010-09-011-20/+9
| | | | | | | | | | | | | | | | | | | 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 Dong2010-08-191-19/+50
| | | | | | | | | | | 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
* Change the default time scale for audio/video track during recordingJames Dong2010-08-161-8/+51
| | | | | | | | | | | and reduce rounding errors in calculating the sample duration - Default time scale for tracks other than audio is set to 90000. - Audio track by default uses the audio sampling rate as the time scale. - Default movie time scale remains to be 1000. - The default time scale values will be overwritten by a user-supplied value if exits.

| | | | | | | | | | | | 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

| | | | | | | | | | - Also o do not use the hard-coded profile and levels.

* File writer has a designated writer thread nowJames Dong2010-08-021-49/+215
| | | | | | | | + 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

* Eliminate the linear cost associated with mSampleSizes.size()James Dong2010-07-281-9/+15
| | | | | | | | | | | | | | - The linear cost associated with mSampleSizes.size() call causes the CPU load to increase overtime as more and more audio/video samples are recorded. - Other Lists used in the MP4 file writer may have similar issues, but the size() call is not made for each output audio/video output sample, or the size of the list is bounded (not linear to the total number of audio/video output samples). As for now, we can live with the small cost (tested with 30 minutes long recording). Change-Id: I23bd93ea4256cb0be0c1649760e39e6809eb4946
* Reduce memory usage by the MP4 file writerJames Dong2010-07-281-42/+44

* Interleave the audio and video by defaultJames Dong2010-07-281-2/+2

* Fixed some meta data issues in the recorded mp4 fileJames Dong2010-06-231-31/+68
| | | | | | | | | | | | | | - 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 Dong2010-06-221-1/+19

| | | | | | | | | | | | | | 1. Avoid copying the input recording frames to the encoder via OMX interface for TI video encoder This is a missing change for part one which help reduces the CPU load. 2. Release output buffers as early as possible. This is a little bit helpful, but not critical. TODO: We should save the underlying pointers allocated by the OMX component before we replace them and restore them before we call OMX_FreeBuffer()!
