The BSD grep doesn't know about \s. Moreover, checking for elf (rather
than ELF) seems to make more sense, as that's the format name, not part
of the description.
Patch suggested by geist. Thanks!
- FFMPEG handles the relationship of start time between encoded and decoded
audio data now by using the fTempPacket->dts and the
fDecodedDataBuffer->pkt_dts fields. We still have to manually keep track of
start times for consecutive audio frames though to support returning a number
of audio frames that may assembled of partial AVFrames.
- The start time of the very first audio frame data packet returned by Decode()
is now correctly calculated based on GetNextChunk() start times instead of
being always zero.
- Introduce fRawDecodedAudio that serves as a container to store properties of
the audio frames stored in fDecodedData. This prepares the population of the
fHeader structure with audio frame properties needed to allow clients of
BMediaDecoder::Decode() detect audio format changes in a later commit.
- Remove fStartTime as it is superflous now.
- The reason for compiler complaining about "INT64_C is not defined here" is
gone since the addition of the compiler flag "-D__STDC_CONSTANT_MACROS"
to the Jamfile some time ago. This flag allows C++ to use C99 math features.
- No functional change intended.
- Also change what is printed for video frames. Currently both
debug_fframe_[audio|video] are used in AVCodecDecoder only and thus are
streamlined for their usage there. For example we print the AVFrame.pkt_dts
field instead of the AVFrame.pkt field because the later one is never touched
by AVCodecDecoders usage of the FFMPEG library.
Note: AVFrame.pkt being never touched means that it always contains the value
AV_NOPTS_VALUE making it less useful for debug purposes.
The packages are the bootstrap ones, modified with the "unbootstrap"
script. Not recommended for real use, but this should make playing with
the ARM build a bit simpler.
The libsolv package somehow got lost in the process when I converted
those. Anyone with a copy of the libsolv_bootstrap packages in their
arm generated folder is welcome to "unbootstrap" and upload it.
- There are two main reasons for this refactoring:
1. Prepare using FFMPEGs functionality of audio frame start time assignment
(instead of rolling it ourself) like already done for the video path
(see _LoadNextVideoChunkIfNeededAndAssignStartTime() for reference).
2. Get rid of fChunkBufferOffset (this is a minor reason though).
- Untangle some of the conditional checks to increase readability.
- No functional change intended.
- First method is solely responsible to fill the audio output buffer with
already decoded audio frames.
Second method is solely responsible for decoding the encoded audio data and
put it in the decoded audio output buffer for further processing with the
first method.
This prepares auto detection of audio frame properties for audio formats
where the properties are contained within the encoded audio frame (e.g. MP3),
instead within the audio container format (e.g. WMA). Implementing auto
detection is scheduled for a later commit though.
- Added documentation accordingly.
- No functional change intended.
- Use name that correctly reflects the return value of avcodec_decode_video2().
- Make DO_PROFILING code path of AVCodecDecoder compile again.
- No functional change intended.
As suggested by akshay, there is no reason to do this only for control
transfers. All input transfers can have short packets and we want to
detect those and trigger the "end of transfer" code when a short packet
happens.
Fixes #11087.
- This makes the video output looks more visual appealing. Without bilinear
filtering you would see aliasing artifacts all over the place. Now it looks
more harmonic.
- This get rids of the complain "'UINT64_C' was not declared in this scope" and
allows us to remove the (now superflous) declaration of UINT64_C.
- No functional change intended.
- This should fix the bug where video files that played well before the recent
changes to the FFMPEG Plugin didn't play anymore. Now we apply the essential
video container properties (that were passed by with Setup()) to the
AVCodecContext. Some video formats simply store those properties in the
container only (e.g. AVI, WMV) and not in the video frames itself
(e.g. MPEG2).
Tested with several files from samples.ffmpeg.org and from the FATE suite of
FFMPEG.
* Restore missing definitions of std::nothrow and mynothrow that are
required for the debug build.
* Additionally, cleanup function overrides provided by kernel_cpp,
such that any exceptions in kernel, bootloader or runtime_loader will
trigger a panic.
Same fix as hrev42151 for usb_serial:
When determining the bit to be set for RTS/DTR there was a missing comparison
to op which would've caused a wrong line state to be set.
* The given void pointers are pointers to the actual list items, which
are pointers themselves, so there was an indirection missing
* Fix inverted sort order
This could have caused spurious crashes related to initialization of
the locale kit, most notably this was responsible for triggering a
crashing bug in the plaintext add-on that caused the x86 image
not being able to boot.
I will continue with trying to find the actual crash, too.
