I am trying to add fp32 tiff reading via ffmpeg for cinelerra-gg. we have this routine:
convert_ctx = sws_getCachedContext(convert_ctx, ip->width, ip->height, pix_fmt, frame->get_w(), frame->get_h(), ofmt, SWS_POINT, NULL, NULL, NULL); if( !convert_ctx ) { fprintf(stderr, "FFVideoConvert::convert_picture_frame:" " sws_getCachedContext() failed\n"); fprintf(stderr, "pix_fmt %s \n", av_get_pix_fmt_name(pix_fmt)); fprintf(stderr, "output format %s \n", av_get_pix_fmt_name(ofmt)); return -1; } so for rgbaf32 tiff it prints: FFMPEG::open_decoder: some stream have bad times: /data/data/com.termux/files/home/test_color.tif FFMPEG::open_decoder: some stream have bad times: /data/data/com.termux/files/home/test_color.tif FFVideoConvert::convert_picture_frame: sws_getCachedContext() failed pix_fmt rgbf32le output format rgbaf32le FFVideoConvert::convert_picture_frame: sws_getCachedContext() failed pix_fmt rgbf32le output format rgbf32le for rgba-float pipeline, or FFVideoConvert::convert_picture_frame: sws_getCachedContext() failed pix_fmt rgbf32le output format rgba for rgba-8 pipeline. tiff images from https://github.com/imageio/imageio/files/7697625/TestImages_float32_Photoshop.zip our ffmpeg.C http://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blob;f=cinelerra-5.1/cinelerra/ffmpeg.C;h=e95cc87e6da6f8c835a199db8ea445d9696a8190;hb=HEAD I just added mappings to case BC_RGBA_FLOAT: return AV_PIX_FMT_RGBAF32LE; and from libavcodec case AV_PIX_FMT_RGBAF32LE: return BC_RGBA_FLOAT; did I miss something in setup parameters for this format?
