* Replace invaled timestamp flag "-1" with AV_NOPTSjstebbins2014-01-261-4/+4
| | | | | | | | | -1 is not a good value as a flag for invalid timestamps. There are cases where small negative timestamps are useful. So this eliminates a potential ambiguity. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@6001 b64f7644-9d1e-0410-96f1-a4d463321fa5

* Merging-in the OpenCL Scaling code from the OpenCL branch to trunk. sr552013-09-211-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | Patch originally by the Multicoreware Inc team, followed by improvements and fixes by Micheal Wootton from AMD Inc, OpenCL: This patch implements Bicubic Scaling in OpenCL. Note that HandBrake currently uses Lanczos so the performance difference appears to be much more significant. We may offer an option of BiCubic in software later. Bicubic scaling may appear a bit sharper than the equivalent Lanczos encode and may increase file size a bit. Quality may be better or worse depending on the scaling and content and personal preference towards sharpness. When comparing performance with a custom HandBrake build that runs Software Bicubic to OpenCL Bicubic, performance increase is about 5~7% on average on a modern GPU. Hardware Decode via DXVA: We also have optional DXVA decoding which may come in useful for slower/lower end systems that have a capable GPU. This is only available on input sources that use the libav decode path. Most GPU hardware for decoding is designed for playback, so if you are running on a high end CPU, it will bottleneck the encode process. Requires OpenCL 1.1 or later supporting GPU. Front end changes and testing framework are not included in this patch. This will be resolved later. Patch will be revised further before the UI is implemented. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@5792 b64f7644-9d1e-0410-96f1-a4d463321fa5

| | | | | | | | | | | | | | doing it wrong in some cases. This means Dolby Pro Logic II is now only available for sources with at least L, R, C, Ls, Rs channels (as well as any additional channels), due to some libdca limitations. This will eventually go away when we use our own downmixing for all sources. Further cleanup to follow. Also cleans up usage of audio->config.in.flags (was audio->config.flags.*). git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@4705 b64f7644-9d1e-0410-96f1-a4d463321fa5
* libhb: fix problem with incorrect addition of audio silencejstebbins2012-05-011-0/+2
| | | | | | | | | | | | sync needs the precise duration of a frame of audio and has no way to compute it for passthru audio. So add a duration member to hb_buffer_t and set it in the audio decoders. This should eventually supersede hb_buffer_t member "stop" since it provides redundant information. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@4618 b64f7644-9d1e-0410-96f1-a4d463321fa5
* Rework filter pipelinejstebbins2012-03-271-6/+6
| | | | | | | | | | | | | | | | | | | | This patch enhances the filter objects. The 2 key improvements are: 1. A filter can change the image dimensions as frames pass through it. 2. A filter can output more than one frame. In addition, I have: Moved cropping & scalling into a filter object Added 90 degree rotation to the rotate filter Moved subtitle burn-in rendering to a filter object. Moved VFR/CFR handling into a framerate shaping filter object. Removed render.c since all it's responsibilities got moved to filters. Improves VOBSUB and SSA subtitle handling. Allows subtitle animations. SSA karaoke support. My apologies in advance if anything breaks ;) git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@4546 b64f7644-9d1e-0410-96f1-a4d463321fa5
* add more audio passthru optionsjstebbins2011-08-011-0/+1
| | | | | | | | | | | | | | | | | adds aac and mp3 passthru for mp4 and mkv containers adds dts and dtshd for mp4 container (mkv already had it) Note: The only player known (to me) to support dts(hd) in mp4 is ff/avplay In LinGui there is a new option to limit which passthru codecs will be used by the "Auto Passthru" audio codec options. The CLI already has this ability with "--audio_copy-mask" which is use in conjunction with the "copy" audio codec option. Also corrects some A/V sync issues when video frames are dropped due to a gap detected in the audio. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@4149 b64f7644-9d1e-0410-96f1-a4d463321fa5
* libhb: generalize channel remapping between decoders and encodersjstebbins2011-06-121-0/+3
| | | | | | | | Decoders set the channel map of their output in hb_audio_config_t. Encoders use this information to remap while encoding. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@4052 b64f7644-9d1e-0410-96f1-a4d463321fa5
* Change internal audio representation rangejstebbins2011-04-081-1/+1
| | | | | | | | | | | ...from float [-32768...32767] to float [-1.0...1.0] Using the range [-1.0..1.0] requires fewer translations of the range for our various encoders and decoders. This also gets rid of a hacky translation from float to int to float in decavcodec audio decoding. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@3908 b64f7644-9d1e-0410-96f1-a4d463321fa5

For the moment, presets and interfaces still assume a default of 1, but the notion is to move to having 0 as the default, in the hope it will be louder/clearer. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@2119 b64f7644-9d1e-0410-96f1-a4d463321fa5
* - validate frame sync the way the standard suggests (via checking the frame ↵van2008-12-041-96/+164
| | | | | | | | | | | | crc) rather than looking at multiple frames. This should reduce the probability of mis-identifying random junk as AC-3 to less than 1 in 2^32. - check the crc on every frame so we don't let corrupted data into the decoder. - interpret the PTS as per the standard (it's the time of the first frame that starts in the packet, not the time of the first byte of the packet). Incorrect interpretation was resulting in an average 15ms timing error (worse case 31ms). - do all the PTS calculations in doubles so we don't get round-off error that will desync the audio & video with 44.1KHz audio sources (these can't appear on DVDs but do show up in avi/mkv/... files). - don't rely on the container to give us large enough frame fragments to validate the sync (some containers split audio frames into really small pieces). Instead use the 8K of unused space in the esconfig of the audio object as an accumulation buffer. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@2002 b64f7644-9d1e-0410-96f1-a4d463321fa5
