Sorry, I lied.

The color format COLOR_TI_FormatYUV420PackedSemiPlanar may work with a
input width which can be divided exactly by 4.

The original problem is:
a) In generating caps of encoder's sink_pad,
COLOR_TI_FormatYUV420PackedSemiPlanar is mapped to
GST_VIDEO_FORMAT_NV12 by gst_amc_color_format_to_video_format.

b) In set_format() GST_VIDEO_FORMAT_NV12 is mapped back to
COLOR_FormatYUV420SemiPlanar by gst_amc_video_format_to_color_format.

c) The value of COLOR_FormatYUV420SemiPlanar is 21, which is not
recognized by media codec configuration routine.


You may modify gstamc.c:

static const struct
{
  gint color_format;
  GstVideoFormat video_format;
} color_format_mapping_table[] = {
  {
  COLOR_FormatYUV420Planar, GST_VIDEO_FORMAT_I420}, {
  COLOR_FormatYUV420SemiPlanar, GST_VIDEO_FORMAT_NV12}, {
  COLOR_TI_FormatYUV420PackedSemiPlanar, GST_VIDEO_FORMAT_NV12}, {
  COLOR_TI_FormatYUV420PackedSemiPlanarInterlaced, GST_VIDEO_FORMAT_NV12}, {
  COLOR_QCOM_FormatYUV420SemiPlanar, GST_VIDEO_FORMAT_NV12}, {
  COLOR_QCOM_FormatYUV420PackedSemiPlanar64x32Tile2m8ka, GST_VIDEO_FORMAT_NV12}
};

Move COLOR_TI_FormatYUV420PackedSemiPlanar up to make it as the first
mapping to GST_VIDEO_FORMAT_NV12.

Then let's see whether it works.
