Hi, I am implementing a custom decoder of qualcomm chipset into ffmpeg, have a working linux application for the same. I am able to run decoder, but its closing with aN error as show below.
Note: The output format is nv12 tiled, we have already added support for nv12 tile to yuv420p conversion in libswscale. 0001-NV12-Tile-pixel-format-support-added.patch <http://libav-users.943685.n4.nabble.com/file/n4662340/0001-NV12-Tile-pixel-format-support-added.patch> # *ffmpeg -f h264 -c:v h264_qhw -i no_mans_sky_1080p_10sec.h264 -pix_fmt nv12_tiled -s 1920x1080 -r 30 out_1080p.yuv* ffmpeg version N-80917-gc5096bc Copyright (c) 2000-2016 the FFmpeg developers built with gcc 4.9.2 (crosstool-NG linaro-1.13.1-4.9-2014.09 - Linaro GCC 4.9-2014.09) 20140904 (prerelease) configuration: --prefix=comark_SBC_ffmpeg/ --enable-shared --enable-nonfree --enable-pic --enable-gpl --enable-cross-compile --cross-prefix=arm-linux-gnueabihf- --arch=arm --target-os=linux --extra-cflags=-I../sdl/source/SDL-1.2.15/comark_SBC_SDL//include/SDL/ --extra-ldflags='-L../sdl/source/SDL-1.2.15/comark_SBC_SDL//lib/ -lSDL' libavutil 55. 28.100 / 55. 28.100 libavcodec 57. 48.101 / 57. 48.101 libavformat 57. 41.100 / 57. 41.100 libavdevice 57. 0.102 / 57. 0.102 libavfilter 6. 47.100 / 6. 47.100 libswscale 4. 1.100 / 4. 1.100 libswresample 2. 1.100 / 2. 1.100 libpostproc 54. 0.100 / 54. 0.100 Initialized Params @ 328 in init_params : width = 1920 & height = 1080 Initialized Decoder @ 680 in vdec_set_buffer_requirement : Input Buffer mincount=1 maxcount=32 actualcount=3 ,buffer_size=2097152 ,alignment=2048 @ 703 in vdec_set_buffer_requirement : Output Buffer mincount=6 maxcount=32 actualcount=10 ,buffer_size=3137536 ,alignment=8192 @ 910 in vdec_alloc_h264_mv : Entered vdec_alloc_h264_mv act_width: 1920, act_height: 1080, size: 5570560, alignment 8192 Start Decoder Buffers freed for reconfiguration @ 910 in vdec_alloc_h264_mv : Entered vdec_alloc_h264_mv act_width: 1920, act_height: 1080, size: 5570560, alignment 8192 Buffers allocated for reconfiguration *[h264 @ 0x4a260] decoding for stream 0 failed* Stop Decoder De-Initialized Decoder De-Initialized Params *[h264 @ 0x4a260] Could not find codec parameters for stream 0 (Video: h264 (High), none, 1920x1080): unspecified pixel format *Consider increasing the value for the 'analyzeduration' and 'probesize' options Input #0, h264, from 'no_mans_sky_1080p_10sec.h264': Duration: N/A, bitrate: N/A Stream #0:0: Video: h264 (High), none, 1920x1080, 12.50 fps, 25 tbr, 1200k tbn, 25 tbc File 'out_1080p.yuv' already exists.
