    "format = (string)S16LE, "
    "rate=(int){ 8000, 11025, 12000, 16000, 22050, 24000, 32000, 44100, 48000 }, "
    "channels = (int){1,2};"

2.mp3：
GST_STATIC_CAPS(
    "audio/mpeg, "
    "mpegversion = (int)1"
    "layer = (int) [ 1, 3 ], "
    "rate = (int) { 8000, 11025, 12000, 16000, 22050, 24000, 32000, 44100, 48000 }, "
    "channels = (int){1,2};"
)

3.audio-AAC:
GST_STATIC_CAPS(
    "audio/mpeg, "
    "mpegversion = (int)4, "
Or  "mpegversion = (int) { 2, 4 }, "
    "framed = (bool) false, "
    "format = (string)S16LE, "
    "rate = (int) { 8000, 11025, 22050, 44100, 48000, 96000 }, "
    "channels = (int){1,2};"
)

4.audio-alaw（g711a,pcma）:
GST_STATIC_CAPS(
    "audio/x-alaw, "
    "rate = (int) 8000, "
    "channels = (int) 1;"
)

5.audio-mulaw（g711u,pcmu）:
GST_STATIC_CAPS(
    "audio/x-mulaw, "
    "rate = (int) 8000, "
    "channels = (int) 1;"
)

6.video裸流：
GST_STATIC_CAPS(
    "video/x-raw, "
    "format=(string){ Y444, Y42B, I420, YV12, NV12 }, "
    "width = (int) [128,4096], "
    "height = (int) [128,2160], "
    "framerate = (fraction) [ 15, 60 ] ;"
)

7.video-h264:
GST_STATIC_CAPS(
    "video/x-h264, "
    "width = (int) [128,4096], "
    "height = (int) [128,2160], "
    "profile=(string){ high-4:4:4, high-4:2:2, high-10, high, main, baseline, constrained-baseline, high-4:4:4-intra, high-4:2:2-intra, high-10-intra }, "
    "stream-format = byte-stream, "
    "framerate = (fraction) [ 15, 60 ] ;"
)

8.video-h265:
GST_STATIC_CAPS(
    "video/x-h265, "
    "width = (int) [128,4096], "
    "height = (int) [128,2160], "
    "profile=(string){ high-4:4:4, high-4:2:2, high-10, high, main, baseline, constrained-baseline, high-4:4:4-intra, high-4:2:2-intra, high-10-intra }, "
