* QSV: choose and re-use a "preferred" implementation instead of using ↵Rodeo2013-09-011-1/+1
| | | | | | | | | | MFX_IMPL_AUTO_ANY. This fixes a rare issue where hardware support was detected as available and used in encqsvInit, but MFXInit silently fell back to software in qsv_enc_init (still don't know what that's all about though). git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@5759 b64f7644-9d1e-0410-96f1-a4d463321fa5

* Improve management of titles and jobsjstebbins2012-11-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cleans up several several unavoidable memory leaks caused by old api. Clearly separates titles from jobs. Titles are set during scan and never modified now. Since titles are immutable, this lead to API some changes. For example, We were setting chapter names in the title from the front ends. Now these get set in the job. These new APIs allow us to start moving away from our use of title->job. Eventually, I would like to eliminate title->job completely, but the mac ui is too tightly tied to using this field to allow removing it at this time. So there is temporarily a convenience function used only by the mac ui that allows it to continue using title->job and also use the new APIs. New APIs: typedef struct hb_title_set_s hb_title_set_t; struct hb_title_set_s { hb_list_t * list_title; int feature; // Detected DVD feature title }; hb_title_set_t * hb_get_title_set( hb_handle_t * ); This is just something I added to clean up how "feature title" info is passed. hb_job_t * hb_job_init( hb_title_t * title ); Initializes a new job with default settings from the title. hb_job_t * hb_job_init_by_index( hb_handle_t *h, int title_index ); Same as hb_job_init(). For use by win Interop lib. void hb_job_reset( hb_job_t * job ); Convenience function for the MacUi. Clears audio, subtitle, and filter lists. The macui still uses title->job because it is so intricately tied to it. So I created this convenience function that it can call after adding a job. void hb_job_close( hb_job_t ** job ); Releases the job an all resources it contains. void hb_job_set_advanced_opts( hb_job_t *job, const char *advanced_opts ); Makes a copy of "advanced_opts" and stores in job. Freed by hb_job_close(). void hb_job_set_file( hb_job_t *job, const char *file ); Makes a copy of "file" and stores in job. Freed by hb_job_close(). void hb_chapter_set_title(hb_chapter_t *chapter, const char *title); Makes a copy of "title" and stores in chapter. Freed by hb_chapter_close(). Recommended usage (cli and lingui are updated to do this): job = hb_job_init( title ); // set job settings ... hb_add(h, job); hb_job_close( &job ); I have also added new APIs for managing metadata. These are used to add metadata to a job. void hb_metadata_set_name( hb_metadata_t *metadata, const char *name ); void hb_metadata_set_artist( hb_metadata_t *metadata, const char *artist ); void hb_metadata_set_composer( hb_metadata_t *metadata, const char *composer ); void hb_metadata_set_release_date( hb_metadata_t *metadata, const char *release_date ); void hb_metadata_set_comment( hb_metadata_t *metadata, const char *comment ); void hb_metadata_set_genre( hb_metadata_t *metadata, const char *genre ); void hb_metadata_set_album( hb_metadata_t *metadata, const char *album ); void hb_metadata_set_coverart( hb_metadata_t *metadata, const uint8_t *coverart, int size ); Example: job = hb_job_init( &job ); // set job settings ... hb_metadata_set_artist( job->metadata, "Danny Elfman" ); hb_add(h, job); hb_job_close( &job ); Some APIs have changed in order to avoid using title incorrectly and use the new hb_title_set_t. -void hb_autopassthru_apply_settings( hb_job_t * job, hb_title_t * title ); +void hb_autopassthru_apply_settings( hb_job_t * job ); -void hb_get_preview( hb_handle_t *, hb_title_t *, int, uint8_t * ); +void hb_get_preview( hb_handle_t *, hb_job_t *, int, uint8_t * ); hb_thread_t * hb_scan_init( hb_handle_t *, volatile int * die, const char * path, int title_index, - hb_list_t * list_title, int preview_count, + hb_title_set_t * title_set, int preview_count, int store_previews, uint64_t min_duration ); These APIs have been removed. Win Interop will need some changes. I think what I've provided will be suffecient, but let me know if it's not. -void hb_get_preview_by_index( hb_handle_t *, int, int, uint8_t * ); -void hb_set_anamorphic_size_by_index( hb_handle_t *, int, - int *output_width, int *output_height, - int *output_par_width, int *output_par_height ); git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@5058 b64f7644-9d1e-0410-96f1-a4d463321fa5

* Use a more direct workaround for the DTS-ES XCh decoding issue.Rodeo2012-08-261-12/+0
| | | | | | | | | | The workaround committed in revision 4896 works for now, but if/when we add 6.1 encoding, we'll want to decode that discrete center surround channel. We could special-case it, but the issue would still be present under 64-bit Windows. Instead, disable the buggy assembly optimizations until they are fixed. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@4918 b64f7644-9d1e-0410-96f1-a4d463321fa5

| | | | | | | | | | | | 6.1 now, but libavcodec's assembly optimizations are buggy under Win64, causing audio distortion when canceling the matrixed Cs channel out of Ls and Rs. This can be removed when the bugs are fixed. Note: unlike before, we still present the stream as 6.0/6.1 to users; it simplfies the code and doesn't make much difference since we always downmix to at least 5.1 anyway. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@4896 b64f7644-9d1e-0410-96f1-a4d463321fa5

* libhb: Allow control of audio mix normalizationjstebbins2012-08-011-1/+2
| | | | | | | | | | | | Since switching to libavresample for audio mixing, our output volume levels have been reduced because libavresample does mix level normalization by default. This change applies a patch to libav to allow us to disable this behavior and adds a new field to hb_audio_config_t to allow the hb frontends to control this feature. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@4884 b64f7644-9d1e-0410-96f1-a4d463321fa5

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

| | | | | | | | | | When the duratation of an audio packet is not evenly divisible by the 90khz clock, we were loosing a fraction of a tick per audio packet.

* libhb: work around the lack of 6.1 support for DTS sourcesRodeo2011-09-091-0/+23
| | | | | | | | | | | | libhb doesn't support 6.1 sources and assumes they're 7.0 instead. This breaks downmixing. Libav can decode the DTS-ES 6.1 core of DTS-HD 6.1 audio tracks; tell it to not process the additional channel so that such tracks can be re-encoded correctly. See https://reviews.handbrake.fr/r/200/ for more information. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@4209 b64f7644-9d1e-0410-96f1-a4d463321fa5
* add more audio passthru optionsjstebbins2011-08-011-0/+6
| | | | | | | | | | | | | | | | | 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: fix or simplify several hacks involved with Libav supportjstebbins2011-07-271-593/+286
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For files that are demuxed by Libav, we must share the format context with the decoder iso that it can obtain the codec context for each stream. The code that did this was very convoluted and difficult to understand. It is simplified by simply passing the context in hb_title_t. Reader was closing stream files before the decoder was finished with the context. This created the need to delay the actual close and cache the context. Changed reader so it behaves more like the rest of handbrake's work objects which lets us explicitly close after the decoders are finished. Libav does some probing of the file when av_find_stream_info is called. This probing leaves the format context in a bad state for some files and causes subsequent reads or seeks to misbehave. So open 2 contexts in ffmpeg_open. One is used only for probing, and the other only for reading. decavcodec.c had 2 separate decoders for files demuxed by hb and files demuxed by Libav. They have been combined and simplified. Previously, it was not possible to decode one source audio track multiple times in order to fan it out to multiple output tracks if the file is demuxed by Libav. We were using the codec context from the format context. Since there is only one of these for each stream, we could only do one decode for each stream. Use avcodec_copy_context to make copies of the codec context and allow multiple decodes. This allows removal of a lot of special case code for Libav streams that was necessary to duplicate the output of the decoder. Patch Libav's mkv demux to fix a seek problem. This has been pushed upstreams, so the next time we update Libav, we must remove this patch. git-svn-id: svn://svn.handbrake.fr/HandBrake/trunk@4141 b64f7644-9d1e-0410-96f1-a4d463321fa5
