I'm trying to use h264_mediacodec decoder in my Android app. The decoder is included in my ffmpeg build from master:
Enabled decoders: h264 rawvideo vp8_mediacodec vp9_mediacodec h264_mediacodec vp8 vp9 I have followed the examples, e.g., https://ffmpeg.org/doxygen/trunk/decode__video_8c_source.html and accordingly written this piece of code: if (av_jni_set_java_vm(g_ctx.javaVM, NULL) != 0) LOGW("av_jni_set_java_vm failed!"); AVCodec *av_codec; AVCodecContext *av_ctx; av_codec = avcodec_find_decoder_by_name("h264_mediacodec"); if (av_codec != NULL) LOGW("found h264_mediacodec\n"); av_ctx = avcodec_alloc_context3(av_codec); if (av_ctx != NULL) LOGW("allocated context\n"); int ret = avcodec_open2(av_ctx, av_codec, NULL); if (ret < 0) { char str[AV_ERROR_MAX_STRING_SIZE]; memset(str, 0, sizeof(str)); av_strerror(ret, str, sizeof(str)); LOGW("avcodec_open2 error: %d \"%s\"\n", ret, str); } else { LOGW("avcodec_open2 success\n"); } When it is executed, I get to log: 05-20 15:27:56.638 13664 13664 D Baresip Lib: found h264_mediacodec 05-20 15:27:56.638 13664 13664 D Baresip Lib: allocated context 05-20 15:27:56.638 13664 13664 D Baresip Lib: avcodec_open2 error: -1 "Operation not permitted" Any ideas why avcodec_open2() fails? -- Juha _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
