[PATCH v2] Add "sar" alias to "aspect" option of video encoders
by Andrey Utkin 08 Aug '16

08 Aug '16

It is impossible to pass "aspect" parameter to encoder from ffmpeg CLI because option from lavc/options_table.h is eclipsed by option with same name in ffmpeg_opt.c, which has different meaning (DAR, not SAR). --- v2: Updated tests reference results as suggested by Michael Niedermayer. libavcodec/options_table.h | 1 + tests/ref/fate/api-mjpeg-codec-param | 2 ++ tests/ref/fate/api-png-codec-param | 2 ++ 3 files changed, 5 insertions(+) diff --git a/libavcodec/options_table.h b/libavcodec/options_table.h index d29996f..8efb889 100644 --- a/libavcodec/options_table.h +++ b/libavcodec/options_table.h @@ -254,6 +254,7 @@ static const AVOption avcodec_options[] = { {"median", NULL, 0, AV_OPT_TYPE_CONST, {.i64 = FF_PRED_MEDIAN }, INT_MIN, INT_MAX, V|E, "pred"}, #endif {"aspect", "sample aspect ratio", OFFSET(sample_aspect_ratio), AV_OPT_TYPE_RATIONAL, {.dbl = 0}, 0, 10, V|E}, +{"sar", "sample aspect ratio", OFFSET(sample_aspect_ratio), AV_OPT_TYPE_RATIONAL, {.dbl = 0}, 0, 10, V|E}, {"debug", "print specific debug info", OFFSET(debug), AV_OPT_TYPE_FLAGS, {.i64 = DEFAULT }, 0, INT_MAX, V|A|S|E|D, "debug"}, {"pict", "picture info", 0, AV_OPT_TYPE_CONST, {.i64 = FF_DEBUG_PICT_INFO }, INT_MIN, INT_MAX, V|D, "debug"}, {"rc", "rate control", 0, AV_OPT_TYPE_CONST, {.i64 = FF_DEBUG_RC }, INT_MIN, INT_MAX, V|E, "debug"}, diff --git a/tests/ref/fate/api-mjpeg-codec-param b/tests/ref/fate/api-mjpeg-codec-param index 26822fd..c67d1b1 100644 --- a/tests/ref/fate/api-mjpeg-codec-param +++ b/tests/ref/fate/api-mjpeg-codec-param @@ -62,6 +62,7 @@ stream=0, decode=0 bits_per_coded_sample=0 pred=0 aspect=180/180 + sar=180/180 debug=0x00000000 vismv=0x00000000 cmp=0 @@ -218,6 +219,7 @@ stream=0, decode=1 bits_per_coded_sample=0 pred=0 aspect=180/180 + sar=180/180 debug=0x00000000 vismv=0x00000000 cmp=0 diff --git a/tests/ref/fate/api-png-codec-param b/tests/ref/fate/api-png-codec-param index 46ac8eb..bd53441 100644 --- a/tests/ref/fate/api-png-codec-param +++ b/tests/ref/fate/api-png-codec-param @@ -62,6 +62,7 @@ stream=0, decode=0 bits_per_coded_sample=0 pred=0 aspect=2835/2835 + sar=2835/2835 debug=0x00000000 vismv=0x00000000 cmp=0 @@ -218,6 +219,7 @@ stream=0, decode=1 bits_per_coded_sample=0 pred=0 aspect=2835/2835 + sar=2835/2835 debug=0x00000000 vismv=0x00000000 cmp=0 -- 2.8.2

Changing media formats mid stream
by Roger Pack 08 Aug '16

08 Aug '16

I've run into the case today where (if we understand it correctly) you setup a directshow graph, it advertises media types, then when you "start" the graph, it actually calls through and says "here's your *real* media type". Does ffmpeg internals have any concept of or support for a "changing media type" at runtime? (any other suggestions for how to handle this if it doesn't?) Cheers! -roger-

[GSoC] BDA (DTV) Capture / tuning -- work-in-progress
by Máté Sebők 08 Aug '16

08 Aug '16

Hi, Due to various problems, it's only got this far: - can list DTV Tuners and Receiver Components (in a bit akward way) - ATSC / DVB-T /-S /-C can be selected - DTV channels can be tuned in only to frequency - only video can be recorded/recoded - only mpeg2/NTSC ( ATSC ) works now... others just hangs or crash due to video format differences between graph connection time and running the graph - there is an optional graph (grf) export The mingw64 has broken signatures for a lot of BDA / DVB components, that needs to be replaced with the attached tuner.h.

[PATCH] libavcodec/qsvdec.c: Restoring decoding functionality after unsuccessful merge from libav.
by Ivan Uskov 24 Jul '16

24 Jul '16

Hello All, After commit d30cf57a7b2097b565db02ecfffbdc9c16423d0e qsv-based decoding aborts with crash, there are many incorrect places appeared. The attached patch fixes the issues but keeps new method of the 'sync' variable allocation introduced in commit d30cf57a7b2097b565db02ecfffbdc9c16423d0e. Please review. -- Best regards, Ivan mailto:ivan.uskov@nablet.com
