gb a4d201aaf9 Drop excessive threading that over-complicates synchronisation. 
MPEG-2 & H.264 videos now play but there are other problems (timestamps).
 2010-09-20 12:55:42 +02:00
gb 4c7c0307c4 0.2.0. 2010-09-20 12:55:41 +02:00
gb 49f8bad478 Move VA context reset to AVCodecContext.get_context() as the 
surface sizes can change.
 2010-09-20 12:55:41 +02:00
gb ee000a357b Fix gst_vaapi_display_has_{decoder,encoder}() to check for the entrypoint too. 2010-09-20 12:55:41 +02:00
gb 1b76d72b98 Add GST_VAAPI_ENTRYPOINT_SLICE_ENCODE. 2010-09-20 12:55:41 +02:00
gb 800faf9ea7 Document H.264 / AVC1 format case better. 2010-09-20 12:55:41 +02:00

gb e7c9845374 Complete initialization of the GstVaapiVideoBuffer. Some frames start to show up. 2010-09-20 12:55:41 +02:00
gb 73b50487f3 Add missing GstBaseSink::buffer_alloc() override. i.e. make sure 
to allocate a GstVaapiVideoBuffer instead of a plain GstBuffer
from the peer pad.
 2010-09-20 12:55:41 +02:00
gb f1fc4b52c5 Export gst_vaapi_video_buffer_new(). 2010-09-20 12:55:41 +02:00
gb 8c17e2f99d Fix gst_vaapi_profile_get_caps() to include the "profile" field. 2010-09-20 12:55:41 +02:00
gb 875352c12d Fix comment. 2010-09-20 12:55:41 +02:00

gb 5d1eb8ce89 Add gst_vaapi_decoder_pause(). 2010-09-20 12:55:41 +02:00
gb 2356ceb0d9 Use a GstTask with start/stop semantics for the decoder thread. 2010-09-20 12:55:41 +02:00
gb 5f5ed724dd Drop extraneous var. 2010-09-20 12:55:41 +02:00
gb a1fddf8bcc Add support for GstVaapiSurfaceProxy to GstVaapiVideoBuffer. 2010-09-20 12:55:41 +02:00
gb 0596777703 Fix gst_vaapi_decoder_get_surface() status. 2010-09-20 12:55:41 +02:00
gb bda32435c2 Try to set correct timestamps to the decoded surface proxy. 2010-09-20 12:55:41 +02:00
gb a14711b935 Add timestamps to GstVaapiSurfaceProxy. 2010-09-20 12:55:41 +02:00
gb 7a3934d01d Fix GstVaapiDecoder::destroy(): GASyncQueue is not a GObject, likewise for GstBuffer. 2010-09-20 12:55:41 +02:00
gb 6a3b05dbca Fix destructor, av_parser_close() does destroy the struct already, unliker avcodec_close()... 2010-09-20 12:55:41 +02:00
gb 4350de601b Prefer profile from codec-data if any was found there. 2010-09-20 12:55:40 +02:00
gb 1f4e67503c Improve heuristics to find the best profile. Use the highest one if no 
explicit match on "profile" field.
 2010-09-20 12:55:40 +02:00
gb 1c48fa3a23 Make sure gst_vaapi_decoder_get_surface() gets unblocked on error. 2010-09-20 12:55:40 +02:00
gb 1def875b95 Fix VC-1 codec initialization, it really needs an extradata buffer. 2010-09-20 12:55:40 +02:00
gb 61ae27d84c Split decoder creation with actual resources allocation 
and codec setup (probe). This fixes a memory leak (avctx, pctx)
on destroy and most interestingly makes it possible to
detect unsupported codecs.
 2010-09-20 12:55:40 +02:00
gb ff193a22b9 Move gst_vaapi_decoder_ffmpeg_create() call to object constructor. 2010-09-20 12:55:37 +02:00
gb 89c094d659 Add "codec-data" property for additional codec data. 
e.g. VC-1 sequence headers for elementary streams.
 2010-09-20 12:55:32 +02:00
gb 664542fe2e Cosmetics (weird indentation). 2010-09-20 12:55:32 +02:00
gb 42248445f2 Cosmetics (extraneous variable, debug message). 2010-09-20 12:55:32 +02:00
gb 86afcbb024 Fix check for VA-API enabled FFmpeg. 2010-09-20 12:55:32 +02:00
gb cc28cdbd60 - Add PTS and framerate information. 
- Simplify parsing with an AVCodeParserContext.
 2010-09-20 12:55:32 +02:00
gb 29f1784dd7 Add more error codes. Fix documentation. 2010-09-20 12:55:32 +02:00
gb eddf6b0d6c Fix gst_vaapi_profile_get_codec(). 
Improve gst_vaapi_profile_from_caps() for H.264 & caps with "codec-data".
 2010-09-20 12:55:32 +02:00
gb d7e4bca05b Handle user end-of-streams. Add gst_vaapi_decoder_{start,stop}() helpers. 2010-09-20 12:55:32 +02:00
gb 68101c13b3 Drop useless End-of-Sequence marker. 2010-09-20 12:55:32 +02:00
gb 0d7164c96c Flush stream only if avcodec_decode_video() read something. 
Otherwise, we might still have to seek into the stream.
i.e. keep the data longer.
 2010-09-20 12:55:32 +02:00
gb da3948bdeb Use a recursive mutex so that a single thread can lock 
several times. This fixes decoding of MPEG-2 and H.264
because those created a GstVaapiContext later through
avcodec_decode_video() that was a protected call.
 2010-09-20 12:55:32 +02:00
gb edef951fb2 Regenerate correct clips. 2010-09-20 12:55:32 +02:00
gb 62358dce92 Add decoder demos. Use -c (mpeg2|h264|vc1) to select the codec. 
XXX: only VC-1 decoding works at this time because of awful
bugs left in GstVaapiDecoderFfmpeg et al.
 2010-09-20 12:55:23 +02:00
gb a203d19a35 Add initial (multithreaded) decoder based on FFmpeg. 
There are tons of bugs left:
- Decoder API not nice enough with error conditions
- FFmpeg parser is sometimes broken
- Packets queue can be lost
 2010-04-23 16:05:58 +00:00
gb 5fb146c298 Add surface proxy that holds a reference to the parent surface 
and that returns the surface to that context on destruction.
 2010-04-23 16:00:50 +00:00
gb ecf60d2284 Add VA context abstraction. 2010-04-23 15:59:31 +00:00
gb 6cb6c387e9 Fix VA profiles definitions for gst_vaapi_profile_get_codec() to work. 2010-04-23 10:58:19 +00:00
gb b0493e729c Add a means to cap the number of objects allocated in the pool. 2010-04-21 15:03:31 +00:00
