Lauri Kasanen	46c5693ea3	swscale/output: Altivec-optimize yuv2plane1_8 ./ffmpeg_g -f rawvideo -pix_fmt rgb24 -s hd1080 -i /dev/zero -pix_fmt yuv420p \ -f null -vframes 100 -v error -nostats - 1158 UNITS in planar1, 65528 runs, 8 skips -cpuflags 0 19082 UNITS in planar1, 65533 runs, 3 skips 16.48 speedup ratio. On x86, SSE2 is ~7. Curiously, the Power C version takes as many cycles as the x86 SSE2 version, yikes it's fast. Note that this function uses VSX instructions, but is not marked so. This is because several existing functions also make that mistake. I'll submit a patch moving them once this is reviewed.

Andrey Semashev	fa08345e88	lavf/dashenc: Fix segment duration overflow on fine time bases. When stream time bases are very fine grained (e.g. nanoseconds), 32-bit segment duration may overflow for even for rather small segment duration (about 4 seconds long). Therefore we use 64-bit values for segment duration.	6 years ago
Andreas Rheinhardt	e895b800fe	cbs_h2645: Avoid memcpy when splitting fragment Now memcpy is avoided for NAL units that don't contain 0x03 escape characters. Improves performance of cbs_h2645_fragment_add_nals from 36940 decicycles to 6364 decicycles based on 8 runs with a 5.1 Mb/s H.264 sample (262144 runs each).

Andrey Semashev	281a21ed50	lavf/dashenc: Add support for format-specific file extensions. The file name template options now support a new "$ext$" placeholder, which is replaced with a filename extension specific for the selected file format. This is useful for the new "auto" format mode, when different streams may use different file formats, and it is not possible to specify the correct file name extension exactly. Resolves warnings in the log about webm segments not having webm extensions.	6 years ago
Andrey Semashev	322e53f8ae	lavf/dashenc: Add DASH segment type auto and make it the default This commit restores the ability to create DASH streams with codecs that require different containers that was lost after commit `2efdbf7367`. It adds a new "auto" value for the dash_segment_type option and makes it the default. When in this mode, the segment format will be chosen based on the codec used in the stream: webm for Vorbis, Opus, VP8 or VP9, mp4 otherwise.	6 years ago
